PNG غير مضغوط ويعمل جيدًا لمعظم سيناريوهات الويب وسطح المكتب. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +إذا كنت بحاجة إلى تنسيق مختلف، استبدل `Png` بالقيمة المطلوبة من التعداد. يمكن تضمين الملف المحفوظ مباشرةً في HTML أو PDFs أو طباعته على الملصقات. + +## إنشاء باركود بصفوف مخصصة + +أحيانًا يكون التخطيط المكدس مطلوبًا بعدد محدد من الصفوف بدلاً من الأعمدة. نفس الفئة `BarcodeGenerator` تُظهر خاصية `Rows` لهذا الغرض. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**لماذا الصفوف مهمة:** +عندما يكون الباركود المكدس أطول من عرضه، تحدد خاصية `Rows` عدد الشرائح الأفقية التي يُقسم إليها الرمز. ضبط `Rows = 3` يُنشئ باركودًا مكدسًا بثلاثة صفوف، وهو مفيد لعروض الملصقات الضيقة. + +### ضبط صفوف الباركود ديناميكيًا + +يمكنك حساب عدد الصفوف في وقت التشغيل بناءً على بيانات الإدخال: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +هذه المرونة تتيح لك **ضبط صفوف الباركود** دون الحاجة إلى إعادة تجميع التطبيق. + +## مثال كامل من البداية إلى النهاية + +فيما يلي برنامج واحد يُنشئ كلًا من باركود بأربعة أعمدة وباركود بثلاثة صفوف، موضحًا كيفية ت coexistence التكوينين. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**الناتج المتوقع:** +ظهر ملفان PNG في دليل العمل الخاص بالتطبيق: + +* `DatabarCols4.png` – باركود DataBar Expanded Stacked بأربعة أعمدة عمودية. +* `DatabarRows3.png` – نفس الرمز مُرتب في ثلاثة صفوف أفقية. + +يمكن فتح الصورتين في أي عارض صور أو تضمينهما في عنصر واجهة مستخدم. + +--- + +## أسئلة شائعة وحالات خاصة + +| السؤال | الجواب | +|----------|--------| +| *هل يمكنني استخدام رموز باركود مختلفة؟* | نعم. استبدل `EncodeTypes.DatabarExpandedStacked` بقيمة `EncodeTypes` أخرى (مثل `EncodeTypes.QR`)، لكن خاصيتي `Columns` و `Rows` خاصة بعائلات DataBar. | +| *ماذا لو تجاوز نص البيانات الحد الأقصى للطول؟* | تدعم رموز DataBar Expanded Stacked ما يصل إلى 61 حرفًا رقميًا. تجاوز هذا الحد يُطلق استثناء `ArgumentException`. تحقق من صحة الإدخال قبل تمريره إلى المُولد. | +| *هل يجب إغلاق `BarcodeGenerator`؟* | `BarcodeGenerator` يُطبق الواجهة `IDisposable`. في خدمة طويلة التشغيل، غلفه بكتلة `using` أو استدعِ `Dispose()` يدويًا لتحرير الموارد الأصلية. | +| *هل يمكنني إنشاء SVG بدلاً من PNG؟* | بالتأكيد. استخدم `BarCodeImageFormat.Svg` في طريقة `Save`. | +| *هل المكتبة متوافقة مع .NET Core؟* | Aspose.BarCode for .NET يدعم .NET Core 3.1، .NET 5، .NET 6 وما بعده. لا تحتاج إلى تعديل الكود. | + +--- + +## الخلاصة + +أنت الآن تعرف كيف **تنشئ باركود DataBar بأربعة أعمدة** في C# باستخدام Aspose.BarCode، وكيفية تعديل التخطيط بالصفوف، وكيفية تصدير النتيجة بتنسيق **صورة باركود** ملائم. يُظهر المثال الكامل كلًا من التكوينات القائمة على الأعمدة والصفوف، مما يمنحك أساسًا قويًا لأي سيناريو طباعة ملصقات أو مسح ضوئي عبر الهاتف المحمول. + +**الخطوات التالية** + +* جرّب أحمال بيانات مختلفة وتحقق من توافقها مع الماسحات. +* استكشف خيارات تنسيق إضافية مثل ألوان المقدمة/الخلفية (`generator.Parameters.Barcode.Color`). +* دمج الباركود مع رسومات أخرى باستخدام واجهة `Graphics` لتصميم ملصقات مخصص. + +لا تتردد في تعديل الكود لمشاريع ASP.NET Core أو Windows Forms أو Xamarin—Aspose.BarCode يعمل عبر جميع منصات .NET. برمجة سعيدة!

+``` + +*小贴士：* 始终使用支持 DataBar 系列的扫描仪测试生成的条形码，因为仅凭视觉外观并不能保证可读性。 + +### 保存条形码图像 + +`BarCodeImageFormat` 枚举提供了多种选项（`Png`、`Jpeg`、`Bmp`、`Gif`、`Tiff`）。PNG 为无损格式，适用于大多数 Web 和桌面场景。 + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +如果需要其他格式，只需将 `Png` 替换为相应的枚举值。保存的文件可以直接嵌入 HTML、PDF，或打印到标签上。 + +## 使用自定义行数创建条形码 + +有时需要在特定行数而非列数的堆叠布局。相同的 `BarcodeGenerator` 类提供了 `Rows` 属性来实现此目的。 + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**行数的重要性：** +当堆叠条形码的高度大于宽度时，`Rows` 属性决定符号被划分为多少水平切片。将 `Rows = 3` 设置为三行堆叠条形码，适用于标签宽度较窄的情况。 + +### 动态设置条形码行数 + +您可以根据输入数据在运行时计算行数： + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +这种灵活性让您 **设置条形码行数** 而无需重新编译应用程序。 + +## 完整端到端示例 + +下面的单个程序同时生成 4 列条形码和 3 行条形码，演示两种配置如何共存。 + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long");

+Directory.CreateDirectory(outputFolder); +``` + +> **为什么？** 以编程方式创建文件夹可确保即使在全新机器上，后续的 `Save` 调用也能成功。 + +### 步骤 2：实例化条形码生成器 + +对于 DataBar Omnidirectional 条形码，传入 `EncodeTypes.DatabarOmniDirectional` 和 GS1‑128 数据字符串。 + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **注意：** `BarcodeGenerator` 对象是可复用的；您可以在保存之间更改其参数，以**从相同数据创建多个条形码**。 + +### 步骤 3：设置通用条形码参数 + +最常见的视觉调节是 X‑dimension（模块宽度）和条码高度。两者均以像素为单位。 + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **为什么要设置 X‑dimension？** 较小的 X‑dimension 能产生更高的分辨率，这在图像需要打印或在高 DPI 屏幕上显示时尤为重要。 + +### 步骤 4：保存第一张条形码图像 + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +文件 `DatabarBarHeight30Pixels.png` 现在包含一个高度为 30 像素的 DataBar Omnidirectional 条形码。 + +### 步骤 5：调整条形码高度像素 + +更改高度不需要新的 `BarcodeGenerator` 实例，只需修改参数即可。 + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### 步骤 6：保存第二张条形码图像 + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +现在您拥有两个 PNG 文件，具有不同的**条形码高度像素**，演示了创建**条形码图像**变体是多么简单。 + +## 动态设置条形码高度像素 + +通常您需要一系列高度匹配 UI 元素或打印标签的条形码。下面的辅助方法抽象了高度的更改： + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +现在您可以调用 `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` 在一行代码中**创建高度为 45 像素的条形码图像**。 + +## 在循环中创建多个条形码 + +当您拥有一组产品标识符时，`foreach` 循环可以消除重复代码。此示例展示了如何从 GTIN 数组**创建多个条形码**。 + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +该循环生成三个 PNG 文件，每个文件都有不同的 **条形码高度像素** 值。由于 `SaveBarcodeWithHeight` 辅助方法封装了高度的更改，主循环保持简洁且专注于数据。 + +### 预期输出 + +运行完整示例后，`Barcodes` 文件夹包含： + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +打开任意 PNG 文件，都能看到清晰的 DataBar Omnidirectional 条形码，可被标准移动应用扫描。 + +## 常见陷阱与专业提示 + +| 问题 | 为什么会发生 | 如何避免 | +|------|--------------|----------| +| **错误的 EncodeTypes** | 对 DataBar 使用 1D 类型会生成不可读的图像。 | 始终为 GS1‑128 负载选择 `EncodeTypes.DatabarOmniDirectional`（或其他 DataBar 变体）。 | +| **X‑dimension 不足** | 非常低的 X‑dimension 可能导致细条在低分辨率显示器上消失。 | 在屏幕显示时保持 `XDimension.Pixels` ≥ 2；打印时提高到 3‑4。 | +| **文件路径错误** | 相对路径可能解析到意外的目录。 | 使用 `Path.Combine` 和 `Environment.CurrentDirectory` 构建绝对路径。 | +| **覆盖图像** | 在循环中重复使用相同文件名会覆盖之前的结果。 | 在文件名中加入唯一标识符（例如 GTIN 或时间戳）。 | +| **缺少 NuGet 包** | 代码可以编译，但运行时抛出 `FileNotFoundException`。 | 确认已安装 `Aspose.BarCode` 并在项目中引用它。 | + +## 完整工作示例 + +下面是完整的程序，您可以复制到控制台应用程序中。它包括所有步骤、辅助方法和错误处理。 + +```csharp +using System;

Provedeme vás generováním DataBar Expanded Stacked čárového kódu, nastavením čtyř sloupců a uložením výsledku jako PNG obrázku. + +V tomto průvodci se naučíte: + +* Inicializovat `BarcodeGenerator` pro symbol **DataBar Expanded Stacked**. +* Nastavit počet sloupců na 4 (hlavní požadavek). +* Upravit počet řádků, pokud potřebujete uspořádání ve třech řadách. +* Exportovat čárový kód jako PNG pomocí odpovídajícího **barcode image format**. + +Stačí vám knihovna Aspose.BarCode for .NET (verze 23.10 nebo novější) a vývojové prostředí .NET 6+ jako Visual Studio 2022. Žádné další závislosti nejsou potřeba. + +--- + +## Jak vytvořit 4‑sloupcový databar čárový kód + +Prvním krokem je vytvořit instanci `BarcodeGenerator`, která cílí na symbologii **DataBar Expanded Stacked**. Tato třída zapouzdřuje všechny možnosti vykreslování, takže přepínání mezi rozvržením podle sloupců a řádků je jednoduché. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Proč to funguje:** +`EncodeTypes.DatabarExpandedStacked` říká Aspose.BarCode, aby vytvořil vrstvenou verzi rodiny DataBar. Vlastnost `DataBar.Columns` určuje, kolik vertikálních modulů čárový kód zabírá. Nastavením na 4 splníte požadavek **vytvořit 4‑sloupcový databar čárový kód**. Nakonec `Save` zapíše vizuální reprezentaci na disk pomocí **barcode image format** `Png`. + +### Konfigurace sloupců DataBar Expanded Stacked + +Pokud potřebujete jiný počet sloupců, jednoduše změňte celé číslo přiřazené k `Columns`. Vlastnost akceptuje hodnoty od 1 do 4 pro variantu expanded stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro tip:* Vždy otestujte vygenerovaný čárový kód skenerem, který podporuje rodinu DataBar, protože samotný vzhled nezaručuje čitelnost. + +### Uložení obrázku čárového kódu + +Výčtová hodnota `BarCodeImageFormat` poskytuje několik možností (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG je bezztrátový a dobře funguje ve většině webových i desktopových scénářů. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Pokud potřebujete jiný formát, nahraďte `Png` požadovanou hodnotou výčtu. Uložený soubor lze přímo vložit do HTML, PDF nebo vytisknout na štítky. + +## Vytvoření čárového kódu s vlastním počtem řádků + +Někdy je potřeba vrstvené rozvržení s konkrétním počtem řádků místo sloupců. Stejná třída `BarcodeGenerator` nabízí vlastnost `Rows` pro tento účel. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Proč jsou řádky důležité:** +Když je vrstvený čárový kód vyšší než široký, vlastnost `Rows` určuje, na kolik horizontálních částí je symbol rozdělen. Nastavením `Rows = 3` vytvoříte třířádkový vrstvený čárový kód, což je užitečné pro úzké štítky. + +### Dynamické nastavení řádků čárového kódu + +Počet řádků můžete vypočítat za běhu na základě vstupních dat: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Tato flexibilita vám umožní **nastavit řádky čárového kódu** bez nutnosti překladu aplikace. + +## Kompletní end‑to‑end příklad + +Níže je kompletní program, který generuje jak 4‑sloupcový čárový kód, tak 3‑řádkový čárový kód, a ukazuje, jak obě konfigurace koexistují. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Očekávaný výstup:** +Ve výchozím adresáři aplikace se objeví dva PNG soubory: + +* `DatabarCols4.png` – DataBar Expanded Stacked čárový kód se čtyřmi vertikálními sloupci. +* `DatabarRows3.png` – stejná symbologie uspořádaná ve třech horizontálních řádcích. + +Oba obrázky lze otevřít v libovolném prohlížeči obrázků nebo vložit do UI komponenty. + +--- + +## Často kladené otázky a okrajové případy + +| Otázka | Odpověď | +|----------|--------| +| *Mohu použít jinou symbologii čárového kódu?* | Ano. Nahraďte `EncodeTypes.DatabarExpandedStacked` jinou hodnotou `EncodeTypes` (např. `EncodeTypes.QR`), ale vlastnosti `Columns` a `Rows` jsou specifické pro rodiny DataBar. | +| *Co když řetězec dat překročí maximální délku?* | Symbologie DataBar Expanded Stacked podporuje až 61 číselných znaků. Překročení tohoto limitu vyvolá `ArgumentException`. Ověřte vstup před přiřazením do generátoru. | +| *Musím uvolnit prostředky `BarcodeGenerator`?* | `BarcodeGenerator` implementuje `IDisposable`. V dlouho běžící službě jej obalte do bloku `using` nebo zavolejte `Dispose()` ručně, aby se uvolnily nativní zdroje. | +| *Mohu generovat SVG místo PNG?* | Rozhodně. Použijte `BarCodeImageFormat.Svg` v metodě `Save`. | +| *Je knihovna kompatibilní s .NET Core?* | Aspose.BarCode for .NET podporuje .NET Core 3.1, .NET 5, .NET 6 a novější. Žádné změny kódu nejsou potřeba. | + +--- + +## Závěr + +Nyní víte, jak **vytvořit 4‑sloupcový databar čárový kód** v C# pomocí Aspose.BarCode, jak upravit rozvržení pomocí řádků a jak exportovat výsledek v praktickém **barcode image format**. Kompletní příklad ukazuje jak konfiguraci založenou na sloupcích, tak na řádcích, což vám poskytuje pevný základ pro jakýkoli scénář tisku štítků nebo mobilního skenování. + +**Další kroky** + +* Experimentujte s různými datovými náklady a ověřujte kompatibilitu se skenery. +* Prozkoumejte další možnosti stylování, jako jsou barvy popředí/pozadí (`generator.Parameters.Barcode.Color`). +* Kombinujte čárový kód s další grafikou pomocí API `Graphics` pro vlastní návrhy štítků. + +Neváhejte přizpůsobit kód pro projekty ASP.NET Core, Windows Forms nebo Xamarin — Aspose.BarCode funguje na všech .NET platformách.

Zapouzdřuje typ kódování, datový řetězec a všechny parametry vykreslování. + +### Krok 1: Definujte výstupní složku + +Vyberte složku, do které budou ukládány vygenerované PNG soubory. Použití absolutní cesty zabraňuje neočekávaným problémům s oprávněními. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Proč?** Vytvoření složky programově zajišťuje, že následné volání `Save` uspěje i na novém počítači. + +### Krok 2: Vytvořte instanci generátoru čárových kódů + +Pro čárový kód DataBar Omnidirectional předávejte `EncodeTypes.DatabarOmniDirectional` a datový řetězec GS1‑128. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Poznámka:** Objekt `BarcodeGenerator` je znovupoužitelný; můžete mezi ukládáním měnit jeho parametry a **vytvořit více čárových kódů** ze stejných dat. + +### Krok 3: Nastavte společné parametry čárového kódu + +Nejčastější vizuální úpravy jsou X‑dimenze (šířka modulu) a výška čárového kódu. Obě jsou vyjádřeny v pixelech. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Proč nastavit X‑dimenzi?** Menší X‑dimenze poskytuje vyšší rozlišení, což je důležité, když bude obrázek tištěn nebo zobrazen na obrazovkách s vysokým DPI. + +### Krok 4: Uložte první obrázek čárového kódu + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Soubor `DatabarBarHeight30Pixels.png` nyní obsahuje DataBar Omnidirectional čárový kód vysoký 30 pixelů. + +### Krok 5: Upravit výšku čárového kódu v pixelech + +Změna výšky nevyžaduje novou instanci `BarcodeGenerator` — stačí upravit parametr. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Krok 6: Uložte druhý obrázek čárového kódu + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Nyní máte dva PNG soubory s různou **výškou čárového kódu v pixelech**, což ukazuje, jak snadno lze vytvořit různé **obrázky čárových kódů**. + +## Dynamické nastavení výšky čárového kódu v pixelech + +Často potřebujete sérii čárových kódů s výškami, které odpovídají UI prvkům nebo tištěným štítkům. Následující pomocná metoda abstrahuje změnu výšky: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Nyní můžete zavolat `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` a **vytvořit obrázek čárového kódu** s výškou 45 pixelů v jediném řádku. + +## Vytváření více čárových kódů ve smyčce + +Když máte kolekci identifikátorů produktů, smyčka `foreach` eliminuje opakovaný kód.

Er zijn geen extra afhankelijkheden vereist. + +--- + +## Hoe maak je een 4‑kolom databar barcode + +De eerste stap is het maken van een `BarcodeGenerator`‑instantie die zich richt op de **DataBar Expanded Stacked** symbologie. Deze klasse omvat alle renderopties, waardoor het eenvoudig is om te schakelen tussen kolom‑gebaseerde en rij‑gebaseerde lay-outs. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Waarom dit werkt:** +`EncodeTypes.DatabarExpandedStacked` vertelt Aspose.BarCode om de gestapelde versie van de DataBar‑familie te produceren. De eigenschap `DataBar.Columns` bepaalt hoeveel verticale modules de barcode inneemt. Het instellen op 4 voldoet aan de vereiste om een **4‑kolom databar barcode** te **maken**. Ten slotte schrijft `Save` de visuele weergave naar schijf met het **barcode image format** `Png`. + +### Configureer DataBar Expanded Stacked kolommen + +Als je een ander aantal kolommen nodig hebt, wijzig dan eenvoudig het gehele getal dat aan `Columns` is toegewezen. De eigenschap accepteert waarden van 1 tot 4 voor de expanded stacked variant. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro tip:* Test de gegenereerde barcode altijd met een scanner die de DataBar‑familie ondersteunt, omdat alleen de visuele weergave geen leesbaarheid garandeert. + +### Sla de barcode‑afbeelding op + +De `BarCodeImageFormat`‑enumeratie biedt verschillende opties (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG is verliesvrij en werkt goed voor de meeste web‑ en desktopscenario's. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Als je een ander formaat nodig hebt, vervang dan `Png` door de gewenste enum‑waarde. Het opgeslagen bestand kan direct in HTML, PDF's of op etiketten worden ingevoegd. + +## Maak een barcode met aangepaste rijen + +Soms is een gestapelde lay-out vereist met een specifiek aantal rijen in plaats van kolommen. Dezelfde `BarcodeGenerator`‑klasse biedt een `Rows`‑eigenschap voor dit doel. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Waarom rijen belangrijk zijn:** +Wanneer de gestapelde barcode hoger is dan breed, bepaalt de `Rows`‑eigenschap in hoeveel horizontale segmenten het symbool wordt verdeeld. Het instellen van `Rows = 3` creëert een drie‑rij gestapelde barcode, wat nuttig is voor smalle etiketbreedtes. + +### Stel barcode‑rijen dynamisch in + +Je kunt het aantal rijen tijdens runtime berekenen op basis van invoergegevens: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Deze flexibiliteit stelt je in staat om **barcode‑rijen in te stellen** zonder de applicatie opnieuw te compileren. + +## Volledig end‑to‑end voorbeeld + +Hieronder staat een enkel programma dat zowel een 4‑kolom barcode als een 3‑rij barcode genereert, en laat zien hoe de twee configuraties naast elkaar bestaan. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Verwachte output:** +Twee PNG‑bestanden verschijnen in de werkmap van de applicatie: + +* `DatabarCols4.png` – een DataBar Expanded Stacked barcode met vier verticale kolommen. +* `DatabarRows3.png` – dezelfde symbologie gerangschikt in drie horizontale rijen. + +Beide afbeeldingen kunnen worden geopend in elke afbeeldingsviewer of ingebed in een UI‑controle. + +--- + +## Veelgestelde vragen en randgevallen + +| Vraag | Antwoord | +|----------|--------| +| *Kan ik een andere barcode‑symbologie gebruiken?* | Ja. Vervang `EncodeTypes.DatabarExpandedStacked` door een andere `EncodeTypes`‑waarde (bijv. `EncodeTypes.QR`), maar de `Columns`‑ en `Rows`‑eigenschappen zijn specifiek voor DataBar‑families. | +| *Wat gebeurt er als de gegevensreeks de maximale lengte overschrijdt?* | De DataBar Expanded Stacked symbologie ondersteunt tot 61 numerieke tekens. Het overschrijden van deze limiet veroorzaakt een `ArgumentException`. Valideer de invoer voordat je deze aan de generator toewijst. | +| *Moet ik de `BarcodeGenerator` vrijgeven?* | `BarcodeGenerator` implementeert `IDisposable`. In een langdurige service, wikkel het in een `using`‑blok of roep `Dispose()` handmatig aan om native resources vrij te geven. | +| *Kan ik SVG genereren in plaats van PNG?* | Absoluut.

Deze omvat het coderings‑type, de gegevensreeks en alle weergave‑parameters. + +### Stap 1: Definieer de uitvoermap + +Kies een map waarin de gegenereerde PNG‑bestanden worden opgeslagen. Het gebruik van een absoluut pad voorkomt verrassingen met rechten. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Waarom?** Het programmatically aanmaken van de map garandeert dat de daaropvolgende `Save`‑aanroepen slagen, zelfs op een nieuwe machine. + +### Stap 2: Instantieer de barcode‑generator + +Voor een DataBar Omnidirectional‑barcode, geef `EncodeTypes.DatabarOmniDirectional` en de GS1‑128‑gegevensreeks door. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Opmerking:** Het `BarcodeGenerator`‑object is herbruikbaar; je kunt de parameters tussen opslagen wijzigen om **meerdere barcodes** uit dezelfde gegevens te **maken**. + +### Stap 3: Stel algemene barcode‑parameters in + +De meest voorkomende visuele aanpassingen zijn de X‑dimensie (module‑breedte) en de balkhoogte. Beide worden uitgedrukt in pixels. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Waarom X‑dimensie instellen?** Een kleinere X‑dimensie levert een hogere resolutie op, wat belangrijk is wanneer de afbeelding wordt afgedrukt of weergegeven op schermen met hoge DPI. + +### Stap 4: Sla de eerste barcode‑afbeelding op + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Het bestand `DatabarBarHeight30Pixels.png` bevat nu een DataBar Omnidirectional‑barcode van 30 pixels hoog. + +### Stap 5: Pas de barcode‑hoogte in pixels aan + +Het wijzigen van de hoogte vereist geen nieuwe `BarcodeGenerator`‑instantie—pas gewoon de parameter aan. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Stap 6: Sla de tweede barcode‑afbeelding op + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Nu heb je twee PNG‑bestanden met verschillende **barcode‑hoogte in pixels**, wat laat zien hoe eenvoudig het is om **barcode‑afbeeldingen** te variëren. + +## Barcode‑hoogte in pixels dynamisch instellen + +Vaak heb je een reeks barcodes nodig met hoogtes die passen bij UI‑elementen of afgedrukte labels. De volgende hulpfunctie abstraheert de hoogte‑aanpassing: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Je kunt nu `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` aanroepen om een **barcode‑afbeelding** met een hoogte van 45 pixels in één regel te **maken**. + +## Meerdere barcodes maken in een lus + +Wanneer je een verzameling product‑identifiers hebt, verwijdert een `foreach`‑lus repetitieve code. Dit voorbeeld laat zien hoe je **meerdere barcodes** uit een array van GTIN‑s kunt **maken**. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +De lus produceert drie PNG‑bestanden, elk met een verschillende **barcode‑hoogte in pixels**. Omdat de `SaveBarcodeWithHeight`‑helper de hoogte‑wijziging encapsuleert, blijft de hoofd‑lus overzichtelijk en gericht op de data. + +### Verwachte output + +Na het uitvoeren van het volledige voorbeeld bevat de map `Barcodes`: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Het openen van een PNG toont een scherpe DataBar Omnidirectional‑barcode die kan worden gescand met standaard mobiele apps. + +## Veelvoorkomende valkuilen en pro‑tips + +| Probleem | Waarom het gebeurt | Hoe te vermijden | +|----------|--------------------|------------------| +| **Verkeerde EncodeTypes** | Het gebruik van een 1D‑type voor een DataBar levert een onleesbare afbeelding op. | Kies altijd `EncodeTypes.DatabarOmniDirectional` (of een andere DataBar‑variant) voor GS1‑128‑payloads. | +| **Onvoldoende X‑dimensie** | Een zeer lage X‑dimensie kan dunne balken laten verdwijnen op monitoren met lage resolutie. | Houd `XDimension.Pixels` ≥ 2 voor schermweergave; verhoog naar 3‑4 voor afdrukken. | +| **Bestandspad‑fouten** | Relatieve paden kunnen naar onverwachte mappen verwijzen. | Gebruik `Path.Combine` en `Environment.CurrentDirectory` om absolute paden te bouwen. | +| **Afbeeldingen overschrijven** | Het hergebruiken van dezelfde bestandsnaam in een lus overschrijft eerdere resultaten. | Voeg unieke identifiers (bijv.

Je vindt daar twee PNG‑bestanden: + +* **DatabarAspectRatio15.png** – een compacte barcode geschikt voor labels met beperkte hoogte. +* **DatabarAspectRatio30.png** – een hogere barcode die door veel scanners betrouwbaarder van een afstand wordt gelezen. + +Beide afbeeldingen zijn klaar om in PDF‑bestanden te worden ingebed, afgedrukt op kassabonnen, of verzonden naar een mobiele app. + +## Stap 4: Breid de oplossing uit om een willekeurig aantal barcodes te genereren + +Het patroon hierboven schaalt eenvoudig: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – De lus iterereert over een array van beeldverhoudingen en maakt voor elke waarde een aparte **barcode‑afbeelding**. +* Pas de `EncodeTypes` of de te coderen string aan om QR‑codes, Code 128, of andere symbologieën te produceren zonder de omliggende logica te wijzigen. + +## Praktische tips en veelvoorkomende valkuilen + +| Tip | Explanation | +|-----|-------------| +| **Reuse the same generator** | Het opnieuw initialiseren van `BarcodeGenerator` voor elke afbeelding voegt onnodige overhead toe. Het wijzigen van parameters tussen `Save`‑aanroepen is sneller en gebruikt minder geheugen. | +| **Validate the output folder** | Roep altijd `Directory.CreateDirectory` aan vóór het opslaan; anders gooit `Save` een `DirectoryNotFoundException`. | +| **Choose an appropriate X‑dimension** | Zeer lage pixelwaarden (bijv. 1) kunnen de barcode onleesbaar maken op schermen met lage resolutie. Waarden van 2–3 werken goed voor de meeste printers. | +| **Mind the encoding** | GS1 DataBar verwacht een leidende `(01)` voor GTIN. Als je de haakjes weglaten, kan de bibliotheek een ongeldige barcode genereren. | +| **Test with a real scanner** | Visuele inspectie is niet voldoende. Test de PNG‑bestanden met de daadwerkelijke scanner‑hardware die je wilt gebruiken. | + +## Verwachte output (visuele beschrijving) + +*Beide PNG‑bestanden tonen een donker‑op‑licht DataBar Stacked Omnidirectional barcode. De versie met beeldverhouding 15 is korter, terwijl de versie met beeldverhouding 30 ongeveer twee keer zo hoog is.* + +Als je de afbeeldingen in een document embedt, renderen ze scherp omdat we `XDimension.Pixels = 2` hebben ingesteld. + +## Conclusie + +Je weet nu hoe je **barcode‑afbeeldingen** kunt maken met een **C# barcode generator**, en je kunt **meerdere barcodes genereren** door de beeldverhouding of een andere parameter aan te passen. Het volledige, uitvoerbare voorbeeld toont best practices zoals het hergebruiken van de generator‑instantie, het afhandelen van output‑mappen, en het verifiëren van bestandscreatie. + +Vervolgens kun je het volgende verkennen: + +* Toevoegen van aangepaste kleuren met `generator.Parameters.Barcode.Color` (secundair trefwoord: **c# barcode generator**) +* Exporteren naar andere formaten zoals JPEG of SVG (`BarCodeImageFormat.Jpeg`, `BarCodeImageFormat.Svg`) +* Integreren van de barcode‑creatie‑logica in een Web API om afbeeldingen op aanvraag te leveren (secundair trefwoord + +## Wat moet je hierna leren? + +De volgende tutorials behandelen nauw verwante onderwerpen die voortbouwen op de technieken die in deze gids worden getoond.

We'll walk through generating a DataBar Expanded Stacked barcode, configuring four columns, and saving the result as a PNG image. + +In this guide you will learn how to: + +* Initialise the `BarcodeGenerator` for a **DataBar Expanded Stacked** symbol. +* Set the column count to 4 (the primary requirement). +* Adjust the row count when you need a stacked layout with three rows. +* Export the barcode as a PNG using the appropriate **barcode image format**. + +You only need the Aspose.BarCode for .NET library (version 23.10 or later) and a .NET 6+ development environment such as Visual Studio 2022. No additional dependencies are required. + +--- + +## How to create 4‑column databar barcode + +The first step is to create a `BarcodeGenerator` instance that targets the **DataBar Expanded Stacked** symbology. This class encapsulates all rendering options, making it straightforward to switch between column‑based and row‑based layouts. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Why this works:** +`EncodeTypes.DatabarExpandedStacked` tells Aspose.BarCode to produce the stacked version of the DataBar family. The `DataBar.Columns` property controls how many vertical modules the barcode occupies. Setting it to 4 matches the requirement to **create 4‑column databar barcode**. Finally, `Save` writes the visual representation to disk using the **barcode image format** `Png`. + +### Configure DataBar Expanded Stacked columns + +If you need a different column count, simply change the integer assigned to `Columns`. The property accepts values from 1 to 4 for the expanded stacked variant. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro tip:* Always test the generated barcode with a scanner that supports the DataBar family, because visual appearance alone does not guarantee readability. + +### Save the barcode image + +The `BarCodeImageFormat` enumeration provides several options (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG is loss‑less and works well for most web and desktop scenarios. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +If you need a different format, replace `Png` with the desired enum value. The saved file can be embedded directly into HTML, PDFs, or printed on labels. + +## Create a barcode with custom rows + +Sometimes a stacked layout is required with a specific number of rows instead of columns. The same `BarcodeGenerator` class exposes a `Rows` property for this purpose. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Why rows matter:** +When the stacked barcode is taller than it is wide, the `Rows` property determines how many horizontal slices the symbol is divided into. Setting `Rows = 3` creates a three‑row stacked barcode, which is useful for narrow label widths. + +### Set barcode rows dynamically + +You can compute the row count at runtime based on input data: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +This flexibility lets you **set barcode rows** without recompiling the application. + +## Full end‑to‑end example + +Below is a single program that generates both a 4‑column barcode and a 3‑row barcode, demonstrating how the two configurations coexist. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Expected output:** +Two PNG files appear in the application’s working directory: + +* `DatabarCols4.png` – a DataBar Expanded Stacked barcode with four vertical columns. +* `DatabarRows3.png` – the same symbology arranged in three horizontal rows. + +Both images can be opened in any image viewer or embedded in a UI control. + +--- + +## Common questions and edge cases + +| Question | Answer | +|----------|--------| +| *Can I use a different barcode symbology?* | Yes. Replace `EncodeTypes.DatabarExpandedStacked` with another `EncodeTypes` value (e.g., `EncodeTypes.QR`), but the `Columns` and `Rows` properties are specific to DataBar families. | +| *What if the data string exceeds the maximum length?* | The DataBar Expanded Stacked symbology supports up to 61 numeric characters. Exceeding this limit throws an `ArgumentException`. Validate the input before assigning it to the generator. | +| *Do I need to dispose the `BarcodeGenerator`?* | `BarcodeGenerator` implements `IDisposable`. In a long‑running service, wrap it in a `using` block or call `Dispose()` manually to free native resources. | +| *Can I generate SVG instead of PNG?* | Absolutely. Use `BarCodeImageFormat.Svg` in the `Save` method. | +| *Is the library compatible with .NET Core?* | Aspose.BarCode for .NET supports .NET Core 3.1, .NET 5, .NET 6, and later. No code changes are required. | + +--- + +## Conclusion + +You now know how to **create 4‑column databar barcode** in C# using Aspose.BarCode, how to adjust the layout with rows, and how to export the result in a convenient **barcode image format**. The complete example shows both column‑based and row‑based configurations, giving you a solid foundation for any label‑printing or mobile‑scanning scenario. + +**Next steps** + +* Experiment with different data payloads and verify scanner compatibility. +* Explore additional styling options such as foreground/background colors (`generator.Parameters.Barcode.Color`). +* Combine the barcode with other graphics using the `Graphics` API for custom label designs. + +Feel free to adapt the code for ASP.NET Core, Windows Forms, or Xamarin projects—Aspose.BarCode works across all .NET platforms. Happy coding! + + +## What Should You Learn Next? + + +The following tutorials cover closely related topics that build on the techniques demonstrated in this guide.

you exactly **how to generate barcode** using the Aspose.BarCode library. You’ll see how to control the **barcode height pixels**, save the image, and produce **multiple barcodes** without duplicating code. + +The tutorial covers everything from installing the package to customizing dimensions, so you can copy‑paste a ready‑to‑run example into your project today. + +## Prerequisites + +Before you start, make sure you have: + +* .NET 6.0 SDK or later installed +* Visual Studio 2022 (or any C# IDE) +* NuGet package `Aspose.BarCode` – install with + +```bash +dotnet add package Aspose.BarCode +``` + +No additional dependencies are required. + +## How to generate barcode image with BarcodeGenerator C# + +The core class for creating a barcode image is `BarcodeGenerator`. It encapsulates the encoding type, the data string, and all rendering parameters. + +### Step 1: Define the output folder + +Choose a folder where the generated PNG files will be stored. Using an absolute path avoids permission surprises. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Why?** Creating the folder programmatically guarantees that the subsequent `Save` calls succeed even on a fresh machine. + +### Step 2: Instantiate the barcode generator + +For a DataBar Omnidirectional barcode, pass `EncodeTypes.DatabarOmniDirectional` and the GS1‑128 data string. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Note:** The `BarcodeGenerator` object is reusable; you can change its parameters between saves to **create multiple barcodes** from the same data. + +### Step 3: Set common barcode parameters + +The most common visual tweaks are the X‑dimension (module width) and the bar height. Both are expressed in pixels. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Why set X‑dimension?** A smaller X‑dimension yields higher resolution, which is important when the image will be printed or displayed on high‑DPI screens. + +### Step 4: Save the first barcode image + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +The file `DatabarBarHeight30Pixels.png` now contains a 30‑pixel‑high DataBar Omnidirectional barcode. + +### Step 5: Adjust the barcode height pixels + +Changing the height does not require a new `BarcodeGenerator` instance—just modify the parameter. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Step 6: Save the second barcode image + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Now you have two PNG files with different **barcode height pixels**, demonstrating how easy it is to **create barcode image** variations. + +## Setting barcode height pixels dynamically + +Often you need a series of barcodes with heights that match UI elements or printed labels. The following helper method abstracts the height change: + +```csharp +///

+/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +You can now call `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` to **create barcode image** with a 45‑pixel height in a single line. + +## Creating multiple barcodes in a loop + +When you have a collection of product identifiers, a `foreach` loop eliminates repetitive code. This example shows how to **create multiple barcodes** from an array of GTINs. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +The loop produces three PNG files, each with a distinct **barcode height pixels** value. Because the `SaveBarcodeWithHeight` helper encapsulates the height change, the main loop stays clean and focused on data. + +### Expected output + +After running the full sample, the `Barcodes` folder contains: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Opening any PNG shows a crisp DataBar Omnidirectional barcode that can be scanned by standard mobile apps. + +## Common pitfalls and pro tips + +| Issue | Why it happens | How to avoid it | +|-------|----------------|-----------------| +| **Wrong EncodeTypes** | Using a 1D type for a DataBar will produce an unreadable image. | Always pick `EncodeTypes.DatabarOmniDirectional` (or another DataBar variant) for GS1‑128 payloads. | +| **Insufficient X‑dimension** | Very low X‑dimension can make thin bars disappear on low‑resolution monitors. | Keep `XDimension.Pixels` ≥ 2 for screen display; increase to 3‑4 for printing. | +| **File path errors** | Relative paths may resolve to unexpected directories. | Use `Path.Combine` and `Environment.CurrentDirectory` to build absolute paths. | +| **Overwriting images** | Re‑using the same file name in a loop overwrites previous results. | Include unique identifiers (e.g., GTIN or timestamp) in the file name. | +| **Missing NuGet package** | Code compiles but throws `FileNotFoundException` at runtime. | Verify `Aspose.BarCode` is installed and the project references it. | + +## Full working example + +Below is the complete program you can copy into a console application. It includes all steps, helper methods, and error handling. + +```csharp +using System; +using System.IO; +using Aspose.BarCode.Generation; + +class Program +{ + static void Main() + { + // Prepare output folder + string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); + Directory.CreateDirectory(outputFolder); + + // ---------- Single barcode with two heights ---------- + var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); + + barcode.Parameters.Barcode.XDimension.Pixels = 2; + barcode.Parameters.Barcode.BarHeight.Pixels = 30; + barcode.Save(Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"), + BarCodeImageFormat.Png); + + barcode.Parameters.Barcode.BarHeight.Pixels = 60; + barcode.Save(Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"), + BarCodeImageFormat.Png); + + // ---------- Helper for dynamic heights ---------- + void SaveBarcodeWithHeight(BarcodeGenerator gen, int heightPx, string fileName) + { + gen.Parameters.Barcode.BarHeight.Pixels = heightPx; + gen.Save(fileName, BarCodeImageFormat.Png); + } + + // ---------- Multiple barcodes ---------- + string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; + int[] heights = { 30, 45, 60 }; + + for (int i = 0; i < gtins.Length; i++) + { + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + gen.Parameters.Barcode.XDimension.Pixels = 2; + + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); + } + + Console.WriteLine($"Barcode images created in: {outputFolder}"); + } +} +``` + +Running this program + + +## What Should You Learn Next? + + +The following tutorials cover closely related topics that build on the techniques demonstrated in this guide.

You will learn to generate multiple barcodes, change the aspect ratio, and save each image as a PNG file. + +Generating barcode images is a common task when building inventory systems, point‑of‑sale terminals, or shipping labels. By the end of this tutorial you will have two ready‑to‑use PNG files that demonstrate different aspect ratios, and you will understand how to extend the approach to any number of barcodes. + +## Prerequisites + +Before you start, make sure you have: + +* .NET 6.0 SDK or later installed +* Visual Studio 2022 (or any IDE that supports C#) +* A reference to a barcode library that supports DataBar Stacked Omnidirectional (for example, **Aspose.BarCode for .NET**). The code snippets use the Aspose API, but the concepts apply to any library with similar properties. + +You do not need a separate database or web server—this is a plain console application. + +## Step 1: Set up the console project + +Create a new console project and add the barcode library via NuGet. + +```bash +dotnet new console -n BarcodeDemo +cd BarcodeDemo +dotnet add package Aspose.BarCode +``` + +The `dotnet add package` command pulls the latest stable version of **Aspose.BarCode**, which provides the `BarcodeGenerator` class used later. + +## Step 2: Write the full program + +Open *Program.cs* and replace its content with the complete example below. The program creates a **barcode image**, changes the aspect ratio, and saves two PNG files. + +```csharp +using System; +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +namespace BarcodeDemo +{ + class Program + { + static void Main() + { + // ----------------------------------------------------------------- + // 1️⃣ Create a DataBar Stacked Omnidirectional generator with sample data + // ----------------------------------------------------------------- + // The EncodeTypes enum tells the generator which barcode symbology to use. + // Here we use DataBar Stacked Omnidirectional (GS1 DataBar) and encode + // a sample GTIN (01) followed by a 14‑digit numeric string. + var generator = new BarcodeGenerator( + EncodeTypes.DatabarStackedOmniDirectional, + "(01)12345678901231"); + + // ----------------------------------------------------------------- + // 2️⃣ Configure common parameters (pixel size and X‑dimension) + // ----------------------------------------------------------------- + // XDimension.Pixels controls the width of the smallest bar in the image. + // A value of 2 gives a clear, high‑resolution output without increasing file size. + generator.Parameters.Barcode.XDimension.Pixels = 2; + + // ----------------------------------------------------------------- + // 3️⃣ Set the first aspect ratio (15) and save the image + // ----------------------------------------------------------------- + // AspectRatio influences the height of the barcode relative to its width. + // An aspect ratio of 15 is typical for compact labels. + generator.Parameters.Barcode.DataBar.AspectRatio = 15; + + string outputFolder = "BarcodeOutputs/"; + System.IO.Directory.CreateDirectory(outputFolder); // Ensure folder exists + + string file15 = $"{outputFolder}DatabarAspectRatio15.png"; + generator.Save(file15, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 15 → {file15}"); + + // ----------------------------------------------------------------- + // 4️⃣ Change the aspect ratio to 30 and save a second image + // ----------------------------------------------------------------- + // A larger aspect ratio (e.g., 30) produces a taller barcode, useful for + // scanning devices that expect more vertical space. + generator.Parameters.Barcode.DataBar.AspectRatio = 30; + + string file30 = $"{outputFolder}DatabarAspectRatio30.png"; + generator.Save(file30, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 30 → {file30}"); + + // ----------------------------------------------------------------- + // 5️⃣ Verify that both files exist + // ----------------------------------------------------------------- + Console.WriteLine("\nVerification:"); + Console.WriteLine($"File 15 exists: {System.IO.File.Exists(file15)}"); + Console.WriteLine($"File 30 exists: {System.IO.File.Exists(file30)}"); + } + } +} +``` + +### Why each part matters + +* **Create barcode image** – The `BarcodeGenerator` constructor initializes the object with the desired symbology and data. +* **c# barcode generator** – The `Parameters` property gives you full control over rendering options; setting `XDimension.Pixels` ensures each bar is crisp on screen. +* **generate multiple barcodes** – By changing `DataBar.AspectRatio` between saves, the same generator instance produces two distinct images without recreating the object, which is more efficient. + +## Step 3: Run the program and view the results + +Execute the application: + +```bash +dotnet run +``` + +You should see console output similar to: + +``` +Saved barcode with aspect ratio 15 → BarcodeOutputs/DatabarAspectRatio15.png +Saved barcode with aspect ratio 30 → BarcodeOutputs/DatabarAspectRatio30.png + +Verification: +File 15 exists: True +File 30 exists: True +``` + +Open the `BarcodeOutputs` folder. You will find two PNG files: + +* **DatabarAspectRatio15.png** – a compact barcode suitable for limited‑height labels. +* **DatabarAspectRatio30.png** – a taller barcode that many scanners read more reliably from a distance. + +Both images are ready to be embedded in PDFs, printed on receipts, or sent to a mobile app. + +## Step 4: Extend the solution to generate any number of barcodes + +The pattern shown above easily scales: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – The loop iterates over an array of aspect ratios, creating a distinct **barcode image** for each value. +* Adjust the `EncodeTypes` or the encoded string to produce QR codes, Code 128, or other symbologies without changing the surrounding logic. + +## Practical tips and common pitfalls + +| Tip | Explanation | +|-----|-------------| +| **Reuse the same generator** | Re‑initializing `BarcodeGenerator` for every image adds unnecessary overhead. Changing parameters between `Save` calls is faster and uses less memory. | +| **Validate the output folder** | Always call `Directory.CreateDirectory` before saving; otherwise `Save` throws a `DirectoryNotFoundException`. | +| **Choose an appropriate X‑dimension** | Very low pixel values (e.g., 1) can make the barcode unreadable on low‑resolution screens. Values of 2–3 work well for most printers. | +| **Mind the encoding** | GS1 DataBar expects a leading `(01)` for GTIN. If you omit the parentheses, the library may generate an invalid barcode. | +| **Test with a real scanner** | Visual inspection is not enough. Test the PNG files with the actual scanner hardware you plan to use. | + +## Expected output (visual description) + +*Both PNG files display a dark‑on‑light DataBar Stacked Omnidirectional barcode. The version with aspect ratio 15 is shorter, while the version with aspect ratio 30 is roughly twice as tall.* + +If you embed the images in a document, they will render sharply because we set `XDimension.Pixels = 2`. + +## Conclusion + +You now know how to **create barcode image** files using a **C# barcode generator**, and you can **generate multiple barcodes** by adjusting the aspect ratio or any other parameter. The complete, runnable example demonstrates best practices such as reusing the generator instance, handling output directories, and verifying file creation. + +Next, you might explore: + +* Adding custom colors with `generator.Parameters.Barcode.Color` (secondary keyword: **c# barcode generator**) +* Exporting to other formats like JPEG or SVG (`BarCodeImageFormat.Jpeg`, `BarCodeImageFormat.Svg`) +* Integrating the barcode creation logic into a Web API to serve images on demand (secondary keyword + + +## What Should You Learn Next? + + +The following tutorials cover closely related topics that build on the techniques demonstrated in this guide. Each resource includes complete working code examples with step-by-step explanations to help you master additional API features and explore alternative implementation approaches in your own projects.

Nous parcourrons la génération d’un code‑barres DataBar Expanded Stacked, la configuration de quatre colonnes et l’enregistrement du résultat sous forme d’image PNG. + +Dans ce guide, vous apprendrez à : + +* Initialiser le `BarcodeGenerator` pour un symbole **DataBar Expanded Stacked**. +* Définir le nombre de colonnes à 4 (l’exigence principale). +* Ajuster le nombre de lignes lorsque vous avez besoin d’une disposition empilée avec trois lignes. +* Exporter le code‑barres au format PNG en utilisant le **format d’image de code‑barres** approprié. + +Vous avez seulement besoin de la bibliothèque Aspose.BarCode for .NET (version 23.10 ou ultérieure) et d’un environnement de développement .NET 6+ tel que Visual Studio 2022. Aucune dépendance supplémentaire n’est requise. + +--- + +## Comment créer un code‑barres databar à 4 colonnes + +La première étape consiste à créer une instance de `BarcodeGenerator` qui cible la symbologie **DataBar Expanded Stacked**. Cette classe encapsule toutes les options de rendu, ce qui facilite le passage entre les dispositions basées sur les colonnes et celles basées sur les lignes. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Pourquoi cela fonctionne :** +`EncodeTypes.DatabarExpandedStacked` indique à Aspose.BarCode de produire la version empilée de la famille DataBar. La propriété `DataBar.Columns` contrôle le nombre de modules verticaux occupés par le code‑barres. La définir à 4 correspond à l’exigence de **créer un code‑barres databar à 4 colonnes**. Enfin, `Save` écrit la représentation visuelle sur le disque en utilisant le **format d’image de code‑barres** `Png`. + +### Configurer les colonnes du DataBar Expanded Stacked + +Si vous avez besoin d’un nombre de colonnes différent, modifiez simplement l’entier attribué à `Columns`. La propriété accepte des valeurs de 1 à 4 pour la variante expanded stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Astuce :* Testez toujours le code‑barres généré avec un lecteur qui prend en charge la famille DataBar, car l’apparence visuelle seule ne garantit pas la lisibilité. + +### Enregistrer l’image du code‑barres + +L’énumération `BarCodeImageFormat` propose plusieurs options (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG est sans perte et fonctionne bien pour la plupart des scénarios web et desktop. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Si vous avez besoin d’un format différent, remplacez `Png` par la valeur d’énumération souhaitée. Le fichier enregistré peut être intégré directement dans du HTML, des PDF, ou imprimé sur des étiquettes. + +## Créer un code‑barres avec des lignes personnalisées + +Parfois, une disposition empilée nécessite un nombre spécifique de lignes au lieu de colonnes. La même classe `BarcodeGenerator` expose une propriété `Rows` à cet effet. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Pourquoi les lignes comptent :** +Lorsque le code‑barres empilé est plus haut que large, la propriété `Rows` détermine en combien de tranches horizontales le symbole est divisé. Définir `Rows = 3` crée un code‑barres empilé à trois lignes, ce qui est utile pour des largeurs d’étiquette étroites. + +### Définir les lignes du code‑barres dynamiquement + +Vous pouvez calculer le nombre de lignes à l’exécution en fonction des données d’entrée : + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Cette flexibilité vous permet de **définir les lignes du code‑barres** sans recompilation de l’application. + +## Exemple complet de bout en bout + +Voici un programme unique qui génère à la fois un code‑barres à 4 colonnes et un code‑barres à 3 lignes, démontrant comment les deux configurations coexistent. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Résultat attendu :** +Deux fichiers PNG apparaissent dans le répertoire de travail de l’application : + +* `DatabarCols4.png` – un code‑barres DataBar Expanded Stacked avec quatre colonnes verticales. +* `DatabarRows3.png` – la même symbologie disposée en trois lignes horizontales. + +Les deux images peuvent être ouvertes avec n’importe quel visualiseur d’images ou intégrées dans un contrôle UI. + +--- + +## Questions fréquentes et cas particuliers + +| Question | Réponse | +|----------|--------| +| *Puis‑je utiliser une symbologie de code‑barres différente ?* | Oui. Remplacez `EncodeTypes.DatabarExpandedStacked` par une autre valeur `EncodeTypes` (par ex., `EncodeTypes.QR`), mais les propriétés `Columns` et `Rows` sont spécifiques aux familles DataBar. | +| *Que se passe-t-il si la chaîne de données dépasse la longueur maximale ?* | La symbologie DataBar Expanded Stacked prend en charge jusqu’à 61 caractères numériques. Dépasser cette limite génère une `ArgumentException`. Validez l’entrée avant de l’attribuer au générateur. | +| *Dois‑je disposer du `BarcodeGenerator` ?* | `BarcodeGenerator` implémente `IDisposable`. Dans un service de longue durée, encapsulez‑le dans un bloc `using` ou appelez `Dispose()` manuellement pour libérer les ressources natives. | +| *Puis‑je générer du SVG au lieu de PNG ?* | Absolument. Utilisez `BarCodeImageFormat.Svg` dans la méthode `Save`. | +| *La bibliothèque est‑elle compatible avec .NET Core ?* | Aspose.BarCode for .NET prend en charge .NET Core 3.1, .NET 5, .NET 6 et les versions ultérieures. Aucun changement de code n’est nécessaire. | + +--- + +## Conclusion + +Vous savez maintenant comment **créer un code‑barres databar à 4 colonnes** en C# avec Aspose.BarCode, comment ajuster la disposition avec des lignes, et comment exporter le résultat dans un **format d’image de code‑barres** pratique. L’exemple complet montre les configurations basées sur les colonnes et sur les lignes, vous offrant une base solide pour tout scénario d’impression d’étiquettes ou de numérisation mobile. + +**Prochaines étapes** + +* Expérimentez avec différents contenus de données et vérifiez la compatibilité du lecteur. +* Explorez des options de style supplémentaires telles que les couleurs de premier plan/arrière‑plan (`generator.Parameters.Barcode.Color`). +* Combinez le code‑barres avec d’autres graphiques en utilisant l’API `Graphics` pour des conceptions d’étiquettes personnalisées. + +N’hésitez pas à adapter le code pour des projets ASP.NET Core, Windows Forms ou Xamarin—Aspose.BarCode fonctionne sur toutes les plateformes .NET.

Les deux sont exprimés en pixels. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Pourquoi définir la X‑dimension ?** Une X‑dimension plus petite donne une résolution plus élevée, ce qui est important lorsque l'image sera imprimée ou affichée sur des écrans à haute densité de pixels (DPI). + +### Étape 4 : Enregistrer la première image de code-barres + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Le fichier `DatabarBarHeight30Pixels.png` contient maintenant un code-barres DataBar Omnidirectional de 30 pixels de hauteur. + +### Étape 5 : Ajuster la hauteur du code-barres en pixels + +Modifier la hauteur ne nécessite pas une nouvelle instance de `BarcodeGenerator` — il suffit de modifier le paramètre. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Étape 6 : Enregistrer la deuxième image de code-barres + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Vous avez maintenant deux fichiers PNG avec des **pixels de hauteur de code-barres** différents, démontrant la facilité de créer des variantes d'**image de code-barres**. + +## Définir dynamiquement les pixels de hauteur du code-barres + +Souvent, vous avez besoin d'une série de codes-barres avec des hauteurs correspondant aux éléments d'interface ou aux étiquettes imprimées. La méthode d'assistance suivante abstrait le changement de hauteur : + +```csharp +///

+/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Vous pouvez maintenant appeler `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` pour **créer une image de code-barres** avec une hauteur de 45 pixels en une seule ligne. + +## Créer plusieurs codes-barres dans une boucle + +Lorsque vous avez une collection d'identifiants de produits, une boucle `foreach` élimine le code répétitif. Cet exemple montre comment **créer plusieurs codes-barres** à partir d'un tableau de GTIN. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +La boucle génère trois fichiers PNG, chacun avec une valeur distincte de **pixels de hauteur du code-barres**. Comme la fonction d'assistance `SaveBarcodeWithHeight` encapsule le changement de hauteur, la boucle principale reste propre et centrée sur les données. + +### Résultat attendu + +Après avoir exécuté l'exemple complet, le dossier `Barcodes` contient : + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Ouvrir n'importe quel PNG montre un code-barres DataBar Omnidirectional net qui peut être scanné par des applications mobiles standard. + +## Pièges courants et astuces pro + +| Problème | Pourquoi cela se produit | Comment l'éviter | +|----------|--------------------------|------------------| +| **EncodeTypes incorrects** | Utiliser un type 1D pour un DataBar produira une image illisible. | Toujours choisir `EncodeTypes.DatabarOmniDirectional` (ou une autre variante DataBar) pour les charges utiles GS1‑128. | +| **X‑dimension insuffisante** | Une X‑dimension très faible peut faire disparaître les barres fines sur des moniteurs à faible résolution. | Conservez `XDimension.Pixels` ≥ 2 pour l'affichage à l'écran ; augmentez à 3‑4 pour l'impression. | +| **Erreurs de chemin de fichier** | Les chemins relatifs peuvent se résoudre vers des répertoires inattendus. | Utilisez `Path.Combine` et `Environment.CurrentDirectory` pour construire des chemins absolus. | +| **Écrasement d'images** | Réutiliser le même nom de fichier dans une boucle écrase les résultats précédents. | Incluez des identifiants uniques (par ex., GTIN ou horodatage) dans le nom de fichier. | +| **Package NuGet manquant** | Le code compile mais lève une `FileNotFoundException` à l'exécution. | Vérifiez que `Aspose.BarCode` est installé et que le projet le référence. | + +## Exemple complet fonctionnel + +Voici le programme complet que vous pouvez copier dans une application console.

Le programme crée une **image de code-barres**, modifie le rapport d'aspect et enregistre deux fichiers PNG. + +```csharp +using System; +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +namespace BarcodeDemo +{ + class Program + { + static void Main() + { + // ----------------------------------------------------------------- + // 1️⃣ Create a DataBar Stacked Omnidirectional generator with sample data + // ----------------------------------------------------------------- + // The EncodeTypes enum tells the generator which barcode symbology to use. + // Here we use DataBar Stacked Omnidirectional (GS1 DataBar) and encode + // a sample GTIN (01) followed by a 14‑digit numeric string. + var generator = new BarcodeGenerator( + EncodeTypes.DatabarStackedOmniDirectional, + "(01)12345678901231"); + + // ----------------------------------------------------------------- + // 2️⃣ Configure common parameters (pixel size and X‑dimension) + // ----------------------------------------------------------------- + // XDimension.Pixels controls the width of the smallest bar in the image. + // A value of 2 gives a clear, high‑resolution output without increasing file size. + generator.Parameters.Barcode.XDimension.Pixels = 2; + + // ----------------------------------------------------------------- + // 3️⃣ Set the first aspect ratio (15) and save the image + // ----------------------------------------------------------------- + // AspectRatio influences the height of the barcode relative to its width. + // An aspect ratio of 15 is typical for compact labels. + generator.Parameters.Barcode.DataBar.AspectRatio = 15; + + string outputFolder = "BarcodeOutputs/"; + System.IO.Directory.CreateDirectory(outputFolder); // Ensure folder exists + + string file15 = $"{outputFolder}DatabarAspectRatio15.png"; + generator.Save(file15, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 15 → {file15}"); + + // ----------------------------------------------------------------- + // 4️⃣ Change the aspect ratio to 30 and save a second image + // ----------------------------------------------------------------- + // A larger aspect ratio (e.g., 30) produces a taller barcode, useful for + // scanning devices that expect more vertical space. + generator.Parameters.Barcode.DataBar.AspectRatio = 30; + + string file30 = $"{outputFolder}DatabarAspectRatio30.png"; + generator.Save(file30, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 30 → {file30}"); + + // ----------------------------------------------------------------- + // 5️⃣ Verify that both files exist + // ----------------------------------------------------------------- + Console.WriteLine("\nVerification:"); + Console.WriteLine($"File 15 exists: {System.IO.File.Exists(file15)}"); + Console.WriteLine($"File 30 exists: {System.IO.File.Exists(file30)}"); + } + } +} +``` + +### Pourquoi chaque partie est importante + +* **Créer une image de code-barres** – Le constructeur `BarcodeGenerator` initialise l'objet avec la symbologie et les données souhaitées. +* **c# barcode generator** – La propriété `Parameters` vous donne un contrôle total sur les options de rendu ; définir `XDimension.Pixels` garantit que chaque barre est nette à l'écran. +* **generate multiple barcodes** – En modifiant `DataBar.AspectRatio` entre les sauvegardes, la même instance du générateur produit deux images distinctes sans recréer l'objet, ce qui est plus efficace. + +## Étape 3 : Exécuter le programme et voir les résultats + +Exécutez l'application : + +```bash +dotnet run +``` + +Vous devriez voir une sortie console similaire à : + +``` +Saved barcode with aspect ratio 15 → BarcodeOutputs/DatabarAspectRatio15.png +Saved barcode with aspect ratio 30 → BarcodeOutputs/DatabarAspectRatio30.png + +Verification: +File 15 exists: True +File 30 exists: True +``` + +Ouvrez le dossier `BarcodeOutputs`. Vous y trouverez deux fichiers PNG : + +* **DatabarAspectRatio15.png** – un code-barres compact adapté aux étiquettes de hauteur limitée. +* **DatabarAspectRatio30.png** – un code-barres plus haut que de nombreux lecteurs lisent plus fiable à distance. + +Les deux images sont prêtes à être intégrées dans des PDF, imprimées sur des reçus ou envoyées à une application mobile. + +## Étape 4 : Étendre la solution pour générer n'importe quel nombre de codes-barres + +Le modèle présenté ci‑dessus s'adapte facilement : + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – La boucle parcourt un tableau de rapports d'aspect, créant une **image de code-barres** distincte pour chaque valeur. +* Ajustez les `EncodeTypes` ou la chaîne encodée pour produire des QR codes, Code 128 ou d'autres symbologies sans modifier la logique environnante. + +## Conseils pratiques et pièges courants + +| Conseil | Explication | +|-----|-------------| +| **Réutiliser le même générateur** | Ré‑initialiser `BarcodeGenerator` pour chaque image ajoute une surcharge inutile. Modifier les paramètres entre les appels `Save` est plus rapide et utilise moins de mémoire. | +| **Valider le dossier de sortie** | Appelez toujours `Directory.CreateDirectory` avant d'enregistrer ; sinon `Save` lève une `DirectoryNotFoundException`. | +| **Choisir une X‑dimension appropriée** | Des valeurs de pixels très faibles (par ex., 1) peuvent rendre le code-barres illisible sur des écrans basse résolution. Des valeurs de 2–3 fonctionnent bien pour la plupart des imprimantes. | +| **Faire attention à l'encodage** | GS1 DataBar attend un préfixe `(01)` pour le GTIN. Si vous omettez les parenthèses, la bibliothèque peut générer un code-barres invalide. | +| **Tester avec un vrai scanner** | L'inspection visuelle ne suffit pas. Testez les fichiers PNG avec le matériel de scanner réel que vous prévoyez d'utiliser. | + +## Résultat attendu (description visuelle) + +*Les deux fichiers PNG affichent un code-barres DataBar Stacked Omnidirectional sombre sur fond clair. La version avec un rapport d'aspect 15 est plus courte, tandis que celle avec un rapport d'aspect 30 est approximativement deux fois plus haute.* + +Si vous intégrez les images dans un document, elles s'afficheront nettes car nous avons défini `XDimension.Pixels = 2`. + +## Conclusion + +Vous savez maintenant comment **créer des fichiers d'image de code-barres** en utilisant un **générateur de code-barres C#**, et vous pouvez **générer plusieurs codes-barres** en ajustant le rapport d'aspect ou tout autre paramètre. L'exemple complet et exécutable montre les meilleures pratiques telles que la réutilisation de l'instance du générateur, la gestion des dossiers de sortie et la vérification de la création des fichiers. + +Ensuite, vous pourriez explorer : + +* Ajouter des couleurs personnalisées avec `generator.Parameters.Barcode.Color` (mot‑clé secondaire : **c# barcode generator**) +* Exporter vers d'autres formats comme JPEG ou SVG (`BarCodeImageFormat.Jpeg`, `BarCodeImageFormat.Svg`) +* Intégrer la logique de création de code-barres dans une Web API pour fournir des images à la demande (mot‑clé secondaire + +## Que devriez‑vous apprendre ensuite ? + +Les tutoriels suivants couvrent des sujets étroitement liés qui s'appuient sur les techniques démontrées dans ce guide.

Wir führen Sie durch die Erzeugung eines DataBar Expanded Stacked‑Barcodes, die Konfiguration von vier Spalten und das Speichern des Ergebnisses als PNG‑Bild. + +In diesem Leitfaden lernen Sie, wie Sie: + +* Initialisieren Sie den `BarcodeGenerator` für ein **DataBar Expanded Stacked**‑Symbol. +* Setzen Sie die Spaltenanzahl auf 4 (die Hauptanforderung). +* Passen Sie die Zeilenanzahl an, wenn Sie ein gestapeltes Layout mit drei Zeilen benötigen. +* Exportieren Sie den Barcode als PNG unter Verwendung des entsprechenden **barcode image format**. + +Sie benötigen lediglich die Aspose.BarCode for .NET‑Bibliothek (Version 23.10 oder höher) und eine .NET 6+ Entwicklungsumgebung wie Visual Studio 2022. Keine zusätzlichen Abhängigkeiten sind erforderlich. + +--- + +## So erstellen Sie einen 4‑Spalten‑Databar‑Barcode + +Der erste Schritt besteht darin, eine `BarcodeGenerator`‑Instanz zu erstellen, die die **DataBar Expanded Stacked**‑Symbolik anvisiert. Diese Klasse kapselt alle Rendering‑Optionen und ermöglicht ein einfaches Umschalten zwischen spalten‑basierten und zeilen‑basierten Layouts. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Warum das funktioniert:** +`EncodeTypes.DatabarExpandedStacked` weist Aspose.BarCode an, die gestapelte Version der DataBar‑Familie zu erzeugen. Die Eigenschaft `DataBar.Columns` steuert, wie viele vertikale Module der Barcode einnimmt. Das Setzen auf 4 entspricht der Anforderung, **einen 4‑Spalten‑Databar‑Barcode zu erstellen**. Schließlich schreibt `Save` die visuelle Darstellung mit dem **barcode image format** `Png` auf die Festplatte. + +### DataBar Expanded Stacked‑Spalten konfigurieren + +Wenn Sie eine andere Spaltenanzahl benötigen, ändern Sie einfach die dem `Columns`‑Parameter zugewiesene Ganzzahl. Die Eigenschaft akzeptiert Werte von 1 bis 4 für die erweiterte gestapelte Variante. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro Tipp:* Testen Sie den erzeugten Barcode stets mit einem Scanner, der die DataBar‑Familie unterstützt, da das reine Aussehen keine Lesbarkeit garantiert. + +### Barcode‑Bild speichern + +Die Aufzählung `BarCodeImageFormat` bietet mehrere Optionen (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG ist verlustfrei und eignet sich gut für die meisten Web‑ und Desktop‑Szenarien. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Wenn Sie ein anderes Format benötigen, ersetzen Sie `Png` durch den gewünschten Enum‑Wert. Die gespeicherte Datei kann direkt in HTML, PDFs eingebettet oder auf Etiketten gedruckt werden. + +## Barcode mit benutzerdefinierten Zeilen erstellen + +Manchmal ist ein gestapeltes Layout mit einer bestimmten Anzahl von Zeilen anstelle von Spalten erforderlich. Die gleiche `BarcodeGenerator`‑Klasse stellt dafür die Eigenschaft `Rows` bereit. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Warum Zeilen wichtig sind:** +Wenn der gestapelte Barcode höher als breit ist, bestimmt die Eigenschaft `Rows`, in wie viele horizontale Abschnitte das Symbol unterteilt wird. Das Setzen von `Rows = 3` erzeugt einen dreizeiligen gestapelten Barcode, was bei schmalen Etikettenbreiten nützlich ist. + +### Barcode‑Zeilen dynamisch festlegen + +Sie können die Zeilenanzahl zur Laufzeit basierend auf Eingabedaten berechnen: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Diese Flexibilität ermöglicht es Ihnen, **Barcode‑Zeilen festzulegen**, ohne die Anwendung neu zu kompilieren. + +## Vollständiges End‑to‑End‑Beispiel + +Unten finden Sie ein einzelnes Programm, das sowohl einen 4‑Spalten‑Barcode als auch einen 3‑Zeilen‑Barcode erzeugt und zeigt, wie die beiden Konfigurationen koexistieren. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Erwartete Ausgabe:** +Zwei PNG‑Dateien erscheinen im Arbeitsverzeichnis der Anwendung: + +* `DatabarCols4.png` – ein DataBar Expanded Stacked‑Barcode mit vier vertikalen Spalten. +* `DatabarRows3.png` – dieselbe Symbolik, angeordnet in drei horizontalen Zeilen. + +Beide Bilder können in jedem Bildbetrachter geöffnet oder in ein UI‑Steuerelement eingebettet werden. + +--- + +## Häufige Fragen und Sonderfälle + +| Frage | Antwort | +|----------|--------| +| *Kann ich eine andere Barcode‑Symbologie verwenden?* | Ja. Ersetzen Sie `EncodeTypes.DatabarExpandedStacked` durch einen anderen `EncodeTypes`‑Wert (z. B. `EncodeTypes.QR`), aber die Eigenschaften `Columns` und `Rows` sind spezifisch für DataBar‑Familien. | +| *Was passiert, wenn die Datenzeichenkette die maximale Länge überschreitet?* | Die DataBar Expanded Stacked‑Symbolik unterstützt bis zu 61 numerische Zeichen. Überschreitet man dieses Limit, wird eine `ArgumentException` ausgelöst. Validieren Sie die Eingabe, bevor Sie sie dem Generator zuweisen. | +| *Muss ich den `BarcodeGenerator` entsorgen?* | `BarcodeGenerator` implementiert `IDisposable`. In einem langlaufenden Service sollten Sie ihn in einem `using`‑Block einbetten oder `Dispose()` manuell aufrufen, um native Ressourcen freizugeben. | +| *Kann ich SVG anstelle von PNG erzeugen?* | Absolut. Verwenden Sie `BarCodeImageFormat.Svg` in der `Save`‑Methode. | +| *Ist die Bibliothek mit .NET Core kompatibel?* | Aspose.BarCode for .NET unterstützt .NET Core 3.1, .NET 5, .NET 6 und neuere Versionen. Es sind keine Code‑Änderungen erforderlich. | + +## Fazit + +Sie wissen jetzt, wie Sie **einen 4‑Spalten‑Databar‑Barcode** in C# mit Aspose.BarCode erstellen, das Layout mit Zeilen anpassen und das Ergebnis in einem praktischen **barcode image format** exportieren. Das vollständige Beispiel zeigt sowohl spalten‑basierte als auch zeilen‑basierte Konfigurationen und bietet Ihnen eine solide Grundlage für jedes Etikett‑Druck‑ oder Mobile‑Scanning‑Szenario. + +**Nächste Schritte** + +* Experimentieren Sie mit verschiedenen Datenpayloads und überprüfen Sie die Scanner‑Kompatibilität. +* Erkunden Sie zusätzliche Styling‑Optionen wie Vorder‑/Hintergrundfarben (`generator.Parameters.Barcode.Color`). +* Kombinieren Sie den Barcode mit anderen Grafiken über die `Graphics`‑API für benutzerdefinierte Etikettendesigns. + +Passen Sie den Code gern für ASP.NET Core, Windows Forms oder Xamarin‑Projekte an – Aspose.BarCode funktioniert auf allen .NET‑Plattformen. Viel Spaß beim Coden! + +## Was sollten Sie als Nächstes lernen? + +Die folgenden Tutorials behandeln eng verwandte Themen, die auf den in diesem Leitfaden gezeigten Techniken aufbauen.

Sie sehen, wie Sie die **Barcode‑Höhe in Pixeln** steuern, das Bild speichern und **mehrere Barcodes** erzeugen, ohne Code zu duplizieren. + +Das Tutorial deckt alles ab, von der Installation des Pakets bis zur Anpassung der Abmessungen, sodass Sie noch heute ein einsatzbereites Beispiel in Ihr Projekt kopieren‑und‑einfügen können. + +## Voraussetzungen + +Bevor Sie beginnen, stellen Sie sicher, dass Sie Folgendes haben: + +* .NET 6.0 SDK oder neuer installiert +* Visual Studio 2022 (oder jede C#‑IDE) +* NuGet‑Paket `Aspose.BarCode` – Installation mit + +```bash +dotnet add package Aspose.BarCode +``` + +Weitere Abhängigkeiten sind nicht erforderlich. + +## Wie man ein Barcode‑Bild mit BarcodeGenerator C# erzeugt + +Die Kernklasse zum Erstellen eines Barcode‑Bildes ist `BarcodeGenerator`. Sie kapselt den Codierungstyp, den Daten‑String und alle Rendering‑Parameter. + +### Schritt 1: Ausgabeverzeichnis festlegen + +Wählen Sie einen Ordner, in dem die erzeugten PNG‑Dateien gespeichert werden. Ein absoluter Pfad verhindert Überraschungen bei Berechtigungen. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Warum?** Das programmgesteuerte Anlegen des Ordners garantiert, dass die nachfolgenden `Save`‑Aufrufe selbst auf einem frischen Rechner erfolgreich sind. + +### Schritt 2: Barcode‑Generator instanziieren + +Für einen DataBar Omnidirectional‑Barcode übergeben Sie `EncodeTypes.DatabarOmniDirectional` und den GS1‑128‑Daten‑String. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Hinweis:** Das `BarcodeGenerator`‑Objekt ist wiederverwendbar; Sie können seine Parameter zwischen den Saves ändern, um **mehrere Barcodes** aus denselben Daten zu **erstellen**. + +### Schritt 3: Gemeinsame Barcode‑Parameter setzen + +Die häufigsten visuellen Anpassungen sind die X‑Dimension (Modulbreite) und die Balkenhöhe. Beide werden in Pixeln angegeben. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Warum X‑Dimension setzen?** Eine kleinere X‑Dimension liefert höhere Auflösung, was wichtig ist, wenn das Bild gedruckt oder auf hochauflösenden Bildschirmen angezeigt wird. + +### Schritt 4: Erstes Barcode‑Bild speichern + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Die Datei `DatabarBarHeight30Pixels.png` enthält nun einen 30‑Pixel‑hohen DataBar Omnidirectional‑Barcode. + +### Schritt 5: Barcode‑Höhe in Pixeln anpassen + +Die Höhe zu ändern erfordert keine neue `BarcodeGenerator`‑Instanz – passen Sie einfach den Parameter an. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Schritt 6: Zweites Barcode‑Bild speichern + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Jetzt haben Sie zwei PNG‑Dateien mit unterschiedlichen **Barcode‑Höhen in Pixeln**, was zeigt, wie einfach es ist, **Barcode‑Bilder** zu variieren. + +## Barcode‑Höhe in Pixeln dynamisch setzen + +Oft benötigen Sie eine Reihe von Barcodes mit Höhen, die zu UI‑Elementen oder gedruckten Etiketten passen. Die folgende Hilfsmethode kapselt die Höhenänderung: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Sie können nun `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` aufrufen, um **Barcode‑Bild** mit einer Höhe von 45 Pixeln in einer einzigen Zeile zu **erstellen**. + +## Mehrere Barcodes in einer Schleife erzeugen + +Wenn Sie eine Sammlung von Produkt‑Identifiers haben, eliminiert eine `foreach`‑Schleife wiederholenden Code. Dieses Beispiel zeigt, wie man **mehrere Barcodes** aus einem Array von GTINs **erstellt**. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +Die Schleife erzeugt drei PNG‑Dateien, jede mit einem anderen **Barcode‑Höhen‑Pixel**‑Wert. Da die Hilfsmethode `SaveBarcodeWithHeight` die Höhenänderung kapselt, bleibt die Hauptschleife sauber und fokussiert auf die Daten. + +### Erwartete Ausgabe + +Nach Ausführen des vollständigen Beispiels enthält der Ordner `Barcodes`: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Das Öffnen einer beliebigen PNG zeigt einen scharfen DataBar Omnidirectional‑Barcode, der von gängigen mobilen Apps gescannt werden kann. + +## Häufige Fallstricke und Profi‑Tipps + +| Problem | Warum es passiert | Wie man es vermeidet | +|---------|-------------------|----------------------| +| **Falsche EncodeTypes** | Verwendung eines 1D‑Typs für einen DataBar erzeugt ein nicht lesbares Bild. | Immer `EncodeTypes.DatabarOmniDirectional` (oder eine andere DataBar‑Variante) für GS1‑128‑Payloads wählen. | +| **Unzureichende X‑Dimension** | Sehr niedrige X‑Dimension kann dünne Balken auf Bildschirmen mit niedriger Auflösung verschwinden lassen. | `XDimension.Pixels` ≥ 2 für Bildschirmanzeige behalten; für Druck auf 3‑4 erhöhen. | +| **Dateipfad‑Fehler** | Relative Pfade können zu unerwarteten Verzeichnissen auflösen. | `Path.Combine` und `Environment.CurrentDirectory` verwenden, um absolute Pfade zu bauen. | +| **Überschreiben von Bildern** | Wiederverwendung desselben Dateinamens in einer Schleife überschreibt vorherige Ergebnisse. | Eindeutige Kennungen (z. B.

Am Ende dieses Tutorials verfügen Sie über zwei einsatzbereite PNG‑Dateien, die unterschiedliche Seitenverhältnisse demonstrieren, und Sie verstehen, wie Sie den Ansatz auf beliebig viele Barcodes ausweiten können. + +## Voraussetzungen + +Bevor Sie beginnen, stellen Sie sicher, dass Sie Folgendes haben: + +* .NET 6.0 SDK oder neuer installiert +* Visual Studio 2022 (oder jede IDE, die C# unterstützt) +* Einen Verweis auf eine Barcode‑Bibliothek, die **DataBar Stacked Omnidirectional** unterstützt (z. B. **Aspose.BarCode for .NET**). Die Code‑Snippets verwenden die Aspose‑API, aber die Konzepte gelten für jede Bibliothek mit ähnlichen Eigenschaften. + +Sie benötigen keine separate Datenbank oder Web‑Server – dies ist eine reine Konsolenanwendung. + +## Schritt 1: Das Konsolenprojekt einrichten + +Erstellen Sie ein neues Konsolenprojekt und fügen Sie die Barcode‑Bibliothek über NuGet hinzu. + +```bash +dotnet new console -n BarcodeDemo +cd BarcodeDemo +dotnet add package Aspose.BarCode +``` + +Der Befehl `dotnet add package` holt die neueste stabile Version von **Aspose.BarCode**, die die später verwendete Klasse `BarcodeGenerator` bereitstellt. + +## Schritt 2: Das vollständige Programm schreiben + +Öffnen Sie *Program.cs* und ersetzen Sie den Inhalt durch das komplette Beispiel unten. Das Programm erstellt ein **barcode image**, ändert das Seitenverhältnis und speichert zwei PNG‑Dateien. + +```csharp +using System; +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +namespace BarcodeDemo +{ + class Program + { + static void Main() + { + // ----------------------------------------------------------------- + // 1️⃣ Create a DataBar Stacked Omnidirectional generator with sample data + // ----------------------------------------------------------------- + // The EncodeTypes enum tells the generator which barcode symbology to use. + // Here we use DataBar Stacked Omnidirectional (GS1 DataBar) and encode + // a sample GTIN (01) followed by a 14‑digit numeric string. + var generator = new BarcodeGenerator( + EncodeTypes.DatabarStackedOmniDirectional, + "(01)12345678901231"); + + // ----------------------------------------------------------------- + // 2️⃣ Configure common parameters (pixel size and X‑dimension) + // ----------------------------------------------------------------- + // XDimension.Pixels controls the width of the smallest bar in the image. + // A value of 2 gives a clear, high‑resolution output without increasing file size. + generator.Parameters.Barcode.XDimension.Pixels = 2; + + // ----------------------------------------------------------------- + // 3️⃣ Set the first aspect ratio (15) and save the image + // ----------------------------------------------------------------- + // AspectRatio influences the height of the barcode relative to its width. + // An aspect ratio of 15 is typical for compact labels. + generator.Parameters.Barcode.DataBar.AspectRatio = 15; + + string outputFolder = "BarcodeOutputs/"; + System.IO.Directory.CreateDirectory(outputFolder); // Ensure folder exists + + string file15 = $"{outputFolder}DatabarAspectRatio15.png"; + generator.Save(file15, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 15 → {file15}"); + + // ----------------------------------------------------------------- + // 4️⃣ Change the aspect ratio to 30 and save a second image + // ----------------------------------------------------------------- + // A larger aspect ratio (e.g., 30) produces a taller barcode, useful for + // scanning devices that expect more vertical space. + generator.Parameters.Barcode.DataBar.AspectRatio = 30; + + string file30 = $"{outputFolder}DatabarAspectRatio30.png"; + generator.Save(file30, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 30 → {file30}"); + + // ----------------------------------------------------------------- + // 5️⃣ Verify that both files exist + // ----------------------------------------------------------------- + Console.WriteLine("\nVerification:"); + Console.WriteLine($"File 15 exists: {System.IO.File.Exists(file15)}"); + Console.WriteLine($"File 30 exists: {System.IO.File.Exists(file30)}"); + } + } +} +``` + +### Warum jeder Teil wichtig ist + +* **Create barcode image** – Der Konstruktor `BarcodeGenerator` initialisiert das Objekt mit der gewünschten Symbolik und den Daten. +* **c# barcode generator** – Die Eigenschaft `Parameters` gibt Ihnen die volle Kontrolle über Render‑Optionen; das Setzen von `XDimension.Pixels` sorgt dafür, dass jede Leiste auf dem Bildschirm scharf erscheint. +* **generate multiple barcodes** – Durch das Ändern von `DataBar.AspectRatio` zwischen den Saves erzeugt dieselbe Generator‑Instanz zwei unterschiedliche Bilder, ohne das Objekt neu zu erstellen, was effizienter ist. + +## Schritt 3: Das Programm ausführen und die Ergebnisse ansehen + +Führen Sie die Anwendung aus: + +```bash +dotnet run +``` + +Sie sollten eine Konsolenausgabe ähnlich der folgenden sehen: + +``` +Saved barcode with aspect ratio 15 → BarcodeOutputs/DatabarAspectRatio15.png +Saved barcode with aspect ratio 30 → BarcodeOutputs/DatabarAspectRatio30.png + +Verification: +File 15 exists: True +File 30 exists: True +``` + +Öffnen Sie den Ordner `BarcodeOutputs`. Dort finden Sie zwei PNG‑Dateien: + +* **DatabarAspectRatio15.png** – ein kompaktes Barcode, geeignet für etiketten mit begrenzter Höhe. +* **DatabarAspectRatio30.png** – ein höheres Barcode, das von vielen Scannern aus größerer Entfernung zuverlässiger gelesen wird. + +Beide Bilder können in PDFs eingebettet, auf Quittungen gedruckt oder an eine mobile App gesendet werden. + +## Schritt 4: Die Lösung erweitern, um beliebig viele Barcodes zu erzeugen + +Das oben gezeigte Muster lässt sich leicht skalieren: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – Die Schleife iteriert über ein Array von Seitenverhältnissen und erstellt für jeden Wert ein eigenes **barcode image**. +* Passen Sie `EncodeTypes` oder den zu codierenden String an, um QR‑Codes, Code 128 oder andere Symboliken zu erzeugen, ohne die umgebende Logik zu ändern. + +## Praktische Tipps und häufige Stolperfallen + +| Tipp | Erklärung | +|-----|-------------| +| **Reuse the same generator** | Das erneute Initialisieren von `BarcodeGenerator` für jedes Bild verursacht unnötigen Overhead. Das Ändern von Parametern zwischen `Save`‑Aufrufen ist schneller und verbraucht weniger Speicher. | +| **Validate the output folder** | Rufen Sie immer `Directory.CreateDirectory` auf, bevor Sie speichern; sonst wirft `Save` eine `DirectoryNotFoundException`. | +| **Choose an appropriate X‑dimension** | Sehr niedrige Pixelwerte (z. B. 1) können das Barcode auf Bildschirmen mit niedriger Auflösung unlesbar machen. Werte von 2–3 funktionieren für die meisten Drucker gut. | +| **Mind the encoding** | GS1 DataBar erwartet ein führendes `(01)` für die GTIN. Wenn Sie die Klammern weglassen, kann die Bibliothek ein ungültiges Barcode erzeugen. | +| **Test with a real scanner** | Visuelle Inspektion reicht nicht aus. Testen Sie die PNG‑Dateien mit der tatsächlichen Scanner‑Hardware, die Sie einsetzen wollen. | + +## Erwartete Ausgabe (visuelle Beschreibung) + +*Beide PNG‑Dateien zeigen ein dunkel‑auf‑hellen DataBar Stacked Omnidirectional Barcode. Die Version mit Seitenverhältnis 15 ist kürzer, während die Version mit Seitenverhältnis 30 etwa doppelt so hoch ist.* + +Wenn Sie die Bilder in ein Dokument einbetten, werden sie scharf dargestellt, weil wir `XDimension.Pixels = 2` gesetzt haben. + +## Fazit + +Sie wissen jetzt, wie Sie **barcode image**‑Dateien mit einem **C# barcode generator** erstellen und **multiple barcodes** erzeugen, indem Sie das Seitenverhältnis oder andere Parameter anpassen.

Δεν απαιτούνται πρόσθετες εξαρτήσεις. + +--- + +## Πώς να δημιουργήσετε barcode databar 4‑στηλών + +Το πρώτο βήμα είναι να δημιουργήσετε μια παρουσία του `BarcodeGenerator` που στοχεύει στη **DataBar Expanded Stacked** συμβολική. Αυτή η κλάση περιλαμβάνει όλες τις επιλογές απόδοσης, καθιστώντας εύκολο το μεταπήδημα μεταξύ διατάξεων με βάση στήλες ή σειρές. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Γιατί λειτουργεί αυτό:** +`EncodeTypes.DatabarExpandedStacked` λέει στο Aspose.BarCode να παραγάγει την στοίβαξη της οικογένειας DataBar. Η ιδιότητα `DataBar.Columns` ελέγχει πόσες κάθετες μονάδες καταλαμβάνει το barcode. Ορίζοντάς το σε 4 ταιριάζει με την απαίτηση **να δημιουργήσετε barcode databar 4‑στηλών**. Τέλος, η μέθοδος `Save` γράφει την οπτική αναπαράσταση στο δίσκο χρησιμοποιώντας το **barcode image format** `Png`. + +### Διαμόρφωση στηλών DataBar Expanded Stacked + +Αν χρειάζεστε διαφορετικό αριθμό στηλών, απλώς αλλάξτε τον ακέραιο που έχει ανατεθεί στο `Columns`. Η ιδιότητα δέχεται τιμές από 1 ως 4 για την παραλλαγή expanded stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Συμβουλή:* Πάντα δοκιμάζετε το παραγόμενο barcode με έναν σαρωτή που υποστηρίζει την οικογένεια DataBar, επειδή η οπτική εμφάνιση από μόνη της δεν εγγυάται την αναγνώσιμότητα. + +### Αποθήκευση της εικόνας barcode + +Η απαρίθμηση `BarCodeImageFormat` παρέχει αρκετές επιλογές (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). Το PNG είναι χωρίς απώλειες και λειτουργεί καλά για τις περισσότερες διαδικτυακές και επιτραπέζιες περιπτώσεις. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Αν χρειάζεστε διαφορετική μορφή, αντικαταστήστε το `Png` με την επιθυμητή τιμή της απαρίθμησης.

Το πρόγραμμα δημιουργεί μια **barcode image**, αλλάζει το aspect ratio και αποθηκεύει δύο αρχεία PNG. + +```csharp +using System; +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +namespace BarcodeDemo +{ + class Program + { + static void Main() + { + // ----------------------------------------------------------------- + // 1️⃣ Create a DataBar Stacked Omnidirectional generator with sample data + // ----------------------------------------------------------------- + // The EncodeTypes enum tells the generator which barcode symbology to use. + // Here we use DataBar Stacked Omnidirectional (GS1 DataBar) and encode + // a sample GTIN (01) followed by a 14‑digit numeric string. + var generator = new BarcodeGenerator( + EncodeTypes.DatabarStackedOmniDirectional, + "(01)12345678901231"); + + // ----------------------------------------------------------------- + // 2️⃣ Configure common parameters (pixel size and X‑dimension) + // ----------------------------------------------------------------- + // XDimension.Pixels controls the width of the smallest bar in the image. + // A value of 2 gives a clear, high‑resolution output without increasing file size. + generator.Parameters.Barcode.XDimension.Pixels = 2; + + // ----------------------------------------------------------------- + // 3️⃣ Set the first aspect ratio (15) and save the image + // ----------------------------------------------------------------- + // AspectRatio influences the height of the barcode relative to its width. + // An aspect ratio of 15 is typical for compact labels. + generator.Parameters.Barcode.DataBar.AspectRatio = 15; + + string outputFolder = "BarcodeOutputs/"; + System.IO.Directory.CreateDirectory(outputFolder); // Ensure folder exists + + string file15 = $"{outputFolder}DatabarAspectRatio15.png"; + generator.Save(file15, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 15 → {file15}"); + + // ----------------------------------------------------------------- + // 4️⃣ Change the aspect ratio to 30 and save a second image + // ----------------------------------------------------------------- + // A larger aspect ratio (e.g., 30) produces a taller barcode, useful for + // scanning devices that expect more vertical space. + generator.Parameters.Barcode.DataBar.AspectRatio = 30; + + string file30 = $"{outputFolder}DatabarAspectRatio30.png"; + generator.Save(file30, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 30 → {file30}"); + + // ----------------------------------------------------------------- + // 5️⃣ Verify that both files exist + // ----------------------------------------------------------------- + Console.WriteLine("\nVerification:"); + Console.WriteLine($"File 15 exists: {System.IO.File.Exists(file15)}"); + Console.WriteLine($"File 30 exists: {System.IO.File.Exists(file30)}"); + } + } +} +``` + +### Γιατί κάθε μέρος είναι σημαντικό + +* **Create barcode image** – Ο κατασκευαστής `BarcodeGenerator` αρχικοποιεί το αντικείμενο με τη ζητούμενη συμβολική και τα δεδομένα. +* **c# barcode generator** – Η ιδιότητα `Parameters` σας δίνει πλήρη έλεγχο πάνω στις επιλογές απόδοσης· ορίζοντας `XDimension.Pixels` εξασφαλίζει ότι κάθε μπάρα είναι καθαρή στην οθόνη. +* **generate multiple barcodes** – Αλλάζοντας το `DataBar.AspectRatio` μεταξύ των αποθηκεύσεων, η ίδια παρουσία του γεννήτριας παράγει δύο διαφορετικές εικόνες χωρίς να δημιουργείται ξανά το αντικείμενο, κάτι που είναι πιο αποδοτικό. + +## Βήμα 3: Εκτελέστε το πρόγραμμα και δείτε τα αποτελέσματα + +Εκτελέστε την εφαρμογή: + +```bash +dotnet run +``` + +Θα πρέπει να δείτε έξοδο κονσόλας παρόμοια με: + +``` +Saved barcode with aspect ratio 15 → BarcodeOutputs/DatabarAspectRatio15.png +Saved barcode with aspect ratio 30 → BarcodeOutputs/DatabarAspectRatio30.png + +Verification: +File 15 exists: True +File 30 exists: True +``` + +Ανοίξτε το φάκελο `BarcodeOutputs`. Θα βρείτε δύο αρχεία PNG: + +* **DatabarAspectRatio15.png** – ένα συμπαγές barcode κατάλληλο για ετικέτες περιορισμένου ύψους. +* **DatabarAspectRatio30.png** – ένα πιο ψηλό barcode που πολλοί σαρωτές διαβάζουν πιο αξιόπιστα από απόσταση. + +Και οι δύο εικόνες είναι έτοιμες να ενσωματωθούν σε PDFs, να εκτυπωθούν σε αποδείξεις ή να σταλούν σε εφαρμογή κινητού. + +## Βήμα 4: Επεκτείνετε τη λύση για να δημιουργήσετε οποιονδήποτε αριθμό barcode + +Το μοτίβο που φαίνεται παραπάνω κλιμακώνεται εύκολα: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – Ο βρόχος διατρέχει έναν πίνακα aspect ratios, δημιουργώντας μια ξεχωριστή **barcode image** για κάθε τιμή. +* Προσαρμόστε τα `EncodeTypes` ή το κωδικοποιημένο συμβολοσειρά για να παραγάγετε QR codes, Code 128 ή άλλες συμβολές χωρίς να αλλάξετε τη λογική γύρω από αυτό. + +## Πρακτικές συμβουλές και κοινά προβλήματα + +| Συμβουλή | Επεξήγηση | +|-----|-------------| +| **Reuse the same generator** | Η επανεκκίνηση του `BarcodeGenerator` για κάθε εικόνα προσθέτει περιττό φόρτο. Η αλλαγή παραμέτρων μεταξύ κλήσεων `Save` είναι πιο γρήγορη και χρησιμοποιεί λιγότερη μνήμη. | +| **Validate the output folder** | Πάντα καλέστε `Directory.CreateDirectory` πριν αποθηκεύσετε· διαφορετικά το `Save` ρίχνει `DirectoryNotFoundException`. | +| **Choose an appropriate X‑dimension** | Πολύ χαμηλές τιμές pixel (π.χ., 1) μπορούν να κάνουν το barcode μη αναγνώσιμο σε οθόνες χαμηλής ανάλυσης. Τιμές 2–3 λειτουργούν καλά για τις περισσότερες εκτυπωτές. | +| **Mind the encoding** | Το GS1 DataBar απαιτεί ένα προθετικό `(01)` για GTIN. Αν παραλείψετε τις παρενθέσεις, η βιβλιοθήκη μπορεί να δημιουργήσει ένα μη έγκυρο barcode. | +| **Test with a real scanner** | Η οπτική επιθεώρηση δεν αρκεί. Δοκιμάστε τα αρχεία PNG με το πραγματικό υλικό σαρωτή που σκοπεύετε να χρησιμοποιήσετε. | + +## Αναμενόμενη έξοδος (προβολή) + +*Και τα δύο αρχεία PNG εμφανίζουν ένα σκούρο‑σε‑ανοιχτό DataBar Stacked Omnidirectional barcode. Η έκδοση με aspect ratio 15 είναι πιο σύντομη, ενώ η έκδοση με aspect ratio 30 είναι περίπου δύο φορές πιο ψηλή.* + +Αν ενσωματώσετε τις εικόνες σε ένα έγγραφο, θα αποδοθούν οξυγόνα επειδή ορίσαμε `XDimension.Pixels = 2`. + +## Συμπέρασμα + +Τώρα ξέρετε πώς να **create barcode image** αρχεία χρησιμοποιώντας μια **C# barcode generator**, και μπορείτε να **generate multiple barcodes** ρυθμίζοντας το aspect ratio ή οποιαδήποτε άλλη παράμετρο. Το πλήρες, εκτελέσιμο παράδειγμα δείχνει βέλτιστες πρακτικές όπως η επαναχρησιμοποίηση της παρουσίας του γεννήτρια, η διαχείριση των φακέλων εξόδου και η επαλήθευση της δημιουργίας αρχείων. + +Στη συνέχεια, μπορείτε να εξερευνήσετε: + +* Προσθήκη προσαρμοσμένων χρωμάτων με `generator.Parameters.Barcode.Color` (δευτερεύον κλειδί: **c# barcode generator**) +* Εξαγωγή σε άλλες μορφές όπως JPEG ή SVG (`BarCodeImageFormat.Jpeg`, `BarCodeImageFormat.Svg`) +* Ενσωμάτωση της λογικής δημιουργίας barcode σε ένα Web API για εξυπηρέτηση εικόνων κατ' απαίτηση (δευτερεύον κλειδί + +## Τι πρέπει να μάθετε στη συνέχεια; + +Τα παρακάτω tutorials καλύπτουν στενά σχετιζόμενα θέματα που βασίζονται στις τεχνικές που παρουσιάστηκαν σε αυτόν τον οδηγό.

+``` + +*Pro tip:* हमेशा जनरेटेड बारकोड को ऐसे स्कैनर से टेस्ट करें जो DataBar परिवार को सपोर्ट करता हो, क्योंकि केवल विज़ुअल अपीयरेंस से रीडेबिलिटी की गारंटी नहीं मिलती। + +### बारकोड इमेज सहेजें + +`BarCodeImageFormat` एनेमरेशन कई विकल्प प्रदान करता है (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`)। PNG लॉस‑लेस है और अधिकांश वेब एवं डेस्कटॉप परिदृश्यों के लिए उपयुक्त है। + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +यदि आपको अलग फॉर्मेट चाहिए, तो `Png` को इच्छित एनेम वैल्यू से बदल दें। सहेजी गई फ़ाइल को सीधे HTML, PDFs में एम्बेड किया जा सकता है या लेबल पर प्रिंट किया जा सकता है। + +## कस्टम रो के साथ बारकोड बनाएं + +कभी‑कभी कॉलम की बजाय एक विशिष्ट रो संख्या के साथ स्टैक्ड लेआउट की आवश्यकता होती है। इसी `BarcodeGenerator` क्लास में इस उद्देश्य के लिए `Rows` प्रॉपर्टी उपलब्ध है। + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long");

+ } +} +``` + +**Why rows matter:** +जब स्टैक्ड बारकोड चौड़ाई से अधिक ऊँचा होता है, तो `Rows` प्रॉपर्टी तय करती है कि सिम्बल को कितनी हॉरिज़ॉन्टल स्लाइस में विभाजित किया जाए। `Rows = 3` सेट करने से तीन‑रो वाला स्टैक्ड बारकोड बनता है, जो संकरी लेबल चौड़ाई के लिए उपयोगी है। + +### बारकोड रो को डायनामिकली सेट करें + +आप इनपुट डेटा के आधार पर रनटाइम पर रो काउंट की गणना कर सकते हैं: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +यह लचीलापन आपको एप्लिकेशन को री‑कम्पाइल किए बिना **बारकोड रो सेट** करने की सुविधा देता है। + +## पूरा एंड‑टू‑एंड उदाहरण + +नीचे एक सिंगल प्रोग्राम दिया गया है जो 4‑कॉलम बारकोड और 3‑रो बारकोड दोनों जेनरेट करता है, यह दर्शाते हुए कि दोनों कॉन्फ़िगरेशन कैसे साथ‑साथ काम कर सकते हैं। + +```csharp +using Aspose.BarCode.Generation;

+``` + +*小技巧：* 請務必使用支援 DataBar 系列的掃描器測試產生的條碼，因為僅憑外觀無法保證可讀性。 + +### 儲存條碼圖像 + +`BarCodeImageFormat` 列舉提供多種選項（`Png`、`Jpeg`、`Bmp`、`Gif`、`Tiff`）。PNG 為無損格式，適用於大多數網頁與桌面情境。 + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +如果需要其他格式，只要將 `Png` 替換為相應的列舉值即可。儲存的檔案可直接嵌入 HTML、PDF，或列印於標籤上。 + +## 建立具自訂列數的條碼 + +有時需要以特定列數而非欄位數的堆疊佈局。相同的 `BarcodeGenerator` 類別提供 `Rows` 屬性以滿足此需求。 + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long");

+ } +} +``` + +**為什麼列數重要：** +當堆疊條碼的高度大於寬度時，`Rows` 屬性決定符號被分割成多少個水平切片。設定 `Rows = 3` 會產生三列堆疊條碼，適合較窄的標籤寬度。 + +### 動態設定條碼列數 + +您可以根據輸入資料在執行時計算列數： + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows;

+``` + +> **注意：** `BarcodeGenerator` 物件可重複使用；您可以在不同的儲存之間變更其參數，以**從相同資料產生多個條碼**。 + +### 步驟 3：設定共用條碼參數 + +最常調整的視覺參數是 X‑dimension（模組寬度）與條碼高度，兩者皆以像素為單位。 + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **為什麼要設定 X‑dimension？** 較小的 X‑dimension 會產生更高的解析度，這在圖像需要列印或在高 DPI 螢幕上顯示時尤為重要。 + +### 步驟 4：儲存第一個條碼圖像 + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +檔案 `DatabarBarHeight30Pixels.png` 現在包含一個高度為 30 像素的 DataBar Omnidirectional 條碼。 + +### 步驟 5：調整條碼高度（像素） + +變更高度不需要重新建立 `BarcodeGenerator` 實例，只需修改參數即可。 + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60;

+``` + +現在您擁有兩個 PNG 檔案，具有不同的**條碼高度（像素）**，示範了**建立條碼圖像**變體是多麼簡單。 + +## 動態設定條碼高度（像素） + +通常您需要一系列高度符合 UI 元件或列印標籤的條碼。以下輔助方法將高度變更抽象化： + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +現在您可以呼叫 `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");`，在單行程式碼中**建立高度為 45 像素的條碼圖像**。 + +## 在迴圈中建立多個條碼 + +當您擁有一系列產品識別碼時，`foreach` 迴圈可避免重複程式碼。此範例示範如何從 GTIN 陣列**建立多個條碼**。 + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}");

További függőségek nem szükségesek. + +--- + +## Hogyan hozzunk létre 4‑oszlopos databar vonalkódot + +Az első lépés egy `BarcodeGenerator` példány létrehozása, amely a **DataBar Expanded Stacked** szimbólumra céloz. Ez az osztály magába foglalja az összes megjelenítési beállítást, így egyszerűen válthatunk az oszlop‑alapú és sor‑alapú elrendezések között. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Why this works:** +`EncodeTypes.DatabarExpandedStacked` azt mondja az Aspose.BarCode‑nak, hogy a DataBar család stacked változatát állítsa elő. A `DataBar.Columns` tulajdonság szabályozza, hány függőleges modulra van szükség a vonalkódban. 4‑re állítva megfelel a **4‑oszlopos databar vonalkód** létrehozásának követelményének. Végül a `Save` a **barcode image format** `Png` használatával írja a vizuális ábrázolást a lemezre. + +### DataBar Expanded Stacked oszlopok konfigurálása + +Ha más oszlopszámra van szükséged, egyszerűen módosítsd a `Columns`‑nak rendelt egész számot. A tulajdonság 1‑től 4‑ig terjedő értékeket fogad el a expanded stacked változatnál. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro tipp:* Mindig teszteld a generált vonalkódot egy, a DataBar családot támogató szkennerrel, mivel a vizuális megjelenés önmagában nem garantálja az olvashatóságot. + +### A vonalkód kép mentése + +A `BarCodeImageFormat` felsorolás több lehetőséget kínál (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). A PNG veszteségmentes, és a legtöbb webes és asztali szituációban jól működik. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Ha más formátumra van szükséged, cseréld le a `Png`‑t a kívánt enum értékre. A mentett fájl közvetlenül beágyazható HTML‑be, PDF‑be, vagy nyomtatható címkékre. + +## Vonalkód létrehozása egyedi sorokkal + +Néha stacked elrendezésre van szükség egy meghatározott sorok számával az oszlopok helyett. Ugyanez a `BarcodeGenerator` osztály egy `Rows` tulajdonságot biztosít erre a célra. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Why rows matter:** +Amikor a stacked vonalkód magasabb, mint széles, a `Rows` tulajdonság meghatározza, hány vízszintes szeletre osztja a szimbólumot. A `Rows = 3` beállítás három soros stacked vonalkódot hoz létre, ami szűk címkeszélességekhez hasznos. + +### A vonalkód sorainak dinamikus beállítása + +A sorok számát futásidőben, a bemeneti adatok alapján számíthatod ki: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Ez a rugalmasság lehetővé teszi, hogy **beállítsd a vonalkód sorait** a program újrafordítása nélkül. + +## Teljes vég‑től‑végig példa + +Az alábbi egyetlen program mind a 4‑oszlopos, mind a 3‑soros vonalkódot generálja, bemutatva, hogyan léteznek együtt a két konfiguráció. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Expected output:** +Két PNG fájl jelenik meg az alkalmazás munkakönyvtárában: + +* `DatabarCols4.png` – egy DataBar Expanded Stacked vonalkód négy függőleges oszloppal. +* `DatabarRows3.png` – ugyanaz a szimbólum három vízszintes sorban elrendezve. + +Mindkét kép megnyitható bármely képnézőben, vagy beágyazható egy UI vezérlőbe. + +--- + +## Gyakori kérdések és szélhelyzetek + +| Question | Answer | +|----------|--------| +| *Can I use a different barcode symbology?* | *Használhatok másik vonalkód szimbólumot?* Igen. Cseréld le a `EncodeTypes.DatabarExpandedStacked`‑t egy másik `EncodeTypes` értékre (például `EncodeTypes.QR`), de a `Columns` és `Rows` tulajdonságok a DataBar családokra specifikusak. | +| *What if the data string exceeds the maximum length?* | *Mi van, ha az adatkarakterlánc meghaladja a maximális hosszúságot?* A DataBar Expanded Stacked szimbólum legfeljebb 61 numerikus karaktert támogat. Ennek a határnak a túllépése `ArgumentException`‑t dob. Ellenőrizd a bemenetet, mielőtt a generátornak átadnád. | +| *Do I need to dispose the `BarcodeGenerator`?* | *Szükséges-e a `BarcodeGenerator` felszabadítása?* `BarcodeGenerator` implementálja az `IDisposable`‑t. Hosszú ideig futó szolgáltatásban csomagold `using` blokkba, vagy hívd meg manuálisan a `Dispose()`‑t a natív erőforrások felszabadításához. | +| *Can I generate SVG instead of PNG?* | *Generálhatok SVG‑t PNG helyett?* Természetesen. Használd a `BarCodeImageFormat.Svg`‑t a `Save` metódusban. | +| *Is the library compatible with .NET Core?* | *Kompatibilis a könyvtár a .NET Core‑ral?* Az Aspose.BarCode for .NET támogatja a .NET Core 3.1, .NET 5, .NET 6 és újabb verziókat. Kódmódosítás nem szükséges. | + +## Összegzés + +Most már tudod, hogyan **hozz létre 4‑oszlopos databar vonalkódot** C#‑ban az Aspose.BarCode használatával, hogyan állíthatod be a sorokkal az elrendezést, és hogyan exportálhatod az eredményt egy kényelmes **barcode image format**‑ban.

Ez magába foglalja a kódolás típusát, az adatkarakterláncot és az összes megjelenítési paramétert. + +### 1. lépés: A kimeneti mappa meghatározása + +Válasszon egy mappát, ahol a generált PNG fájlok tárolódnak. Az abszolút útvonal használata elkerüli a jogosultsági meglepetéseket. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Miért?** A mappa programozott létrehozása garantálja, hogy a későbbi `Save` hívások is sikeresek legyenek még egy tiszta gépen is. + +### 2. lépés: A barcode generator példányosítása + +DataBar Omnidirectional vonalkódhoz adja át a `EncodeTypes.DatabarOmniDirectional` értéket és a GS1‑128 adatkarakterláncot. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Megjegyzés:** A `BarcodeGenerator` objektum újrahasználható; a mentések között módosíthatja a paramétereit, hogy **több vonalkódot** hozzon létre ugyanabból az adatból. + +### 3. lépés: Általános vonalkód paraméterek beállítása + +A leggyakoribb vizuális finomhangolások az X‑dimenzió (modul szélesség) és a vonal magassága. Mindkettő pixelekben van megadva. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Miért állítsuk be az X‑dimenziót?** A kisebb X‑dimenzió nagyobb felbontást eredményez, ami fontos, ha a képet nyomtatni vagy nagy DPI‑jú képernyőn megjeleníteni kell. + +### 4. lépés: Az első vonalkód kép mentése + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +A `DatabarBarHeight30Pixels.png` fájl most egy 30 pixel magas DataBar Omnidirectional vonalkódot tartalmaz. + +### 5. lépés: A vonalkód magasság pixelének módosítása + +A magasság módosításához nem szükséges új `BarcodeGenerator` példány – csak a paramétert kell módosítani. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### 6. lépés: A második vonalkód kép mentése + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Most már két PNG fájlja van különböző **vonalkód magasság pixel** értékekkel, ami bemutatja, milyen egyszerű **vonalkód képek** változatainak **létrehozása**. + +## A vonalkód magasság pixelének dinamikus beállítása + +Gyakran szükség van egy sor vonalkódra, amelyek magassága megegyezik a UI elemekkel vagy a nyomtatott címkékkel. A következő segédmetódus elvonja a magasságváltoztatás részleteit: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Most már meghívhatja a `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` metódust, hogy **vonalkód képet** hozzon létre 45 pixel magassággal egyetlen sorban. + +## Több vonalkód létrehozása ciklusban + +Ha van egy termékazonosítók gyűjteménye, egy `foreach` ciklus megszünteti az ismétlődő kódot. Ez a példa megmutatja, hogyan **hozhat létre több vonalkódot** egy GTIN tömbből. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +A ciklus három PNG fájlt hoz létre, mindegyik egyedi **vonalkód magasság pixel** értékkel. Mivel a `SaveBarcodeWithHeight` segéd a magasságváltoztatást kapszulázza, a fő ciklus tiszta marad és az adatokra koncentrál. + +### Várható kimenet + +A teljes minta futtatása után a `Barcodes` mappa a következőket tartalmazza: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Bármely PNG megnyitása egy tiszta DataBar Omnidirectional vonalkódot mutat, amelyet a szabványos mobilalkalmazások be tudnak olvasni. + +## Gyakori buktatók és profi tippek + +| Probléma | Miért fordul elő | Hogyan kerülhető el | +|----------|------------------|---------------------| +| **Helytelen EncodeTypes** | 1D típus használata DataBar-hoz olvashatatlan képet eredményez. | Mindig válassza a `EncodeTypes.DatabarOmniDirectional` (vagy más DataBar változat) értéket a GS1‑128 terheléshez. | +| **Elégtelen X‑dimenzió** | Nagyon alacsony X‑dimenzió miatt a vékony vonalak eltűnhetnek alacsony felbontású monitorokon. | Tartsa a `XDimension.Pixels` értéket ≥ 2 képernyőn való megjelenítéshez; nyomtatáshoz növelje 3‑4-re. | +| **Fájlútvonal hibák** | A relatív útvonalak váratlan könyvtárakra mutathatnak. | Használja a `Path.Combine` és `Environment.CurrentDirectory` metódusokat abszolút útvonalak építéséhez. | +| **Képek felülírása** | Ugyanazon fájlnév újrahasználata egy ciklusban felülírja a korábbi eredményeket. | Tegyen egyedi azonosítókat (pl.

A paraméterek `Save` hívások közti módosítása gyorsabb és kevesebb memóriát használ. | +| **Ellenőrizd a kimeneti mappát** | Mindig hívd meg a `Directory.CreateDirectory`-t mentés előtt; különben a `Save` `DirectoryNotFoundException`-t dob. | +| **Válassz megfelelő X‑dimenziót** | Nagyon alacsony pixelértékek (pl. 1) olvashatatlanná tehetik a vonalkódot alacsony felbontású képernyőkön. A 2–3 érték a legtöbb nyomtatóhoz jól működik. | +| **Figyelj a kódolásra** | A GS1 DataBar a GTIN-hez vezető `(01)` előtagot várja. Ha kihagyod a zárójeleket, a könyvtár érvénytelen vonalkódot generálhat. | +| **Teszteld valódi szkennerrel** | A vizuális ellenőrzés nem elegendő. Teszteld a PNG fájlokat a tényleges szkennerrel, amelyet használni tervezel. | + +## Expected output (visual description) + +*Mindkét PNG fájl sötét‑fehér DataBar Stacked Omnidirectional vonalkódot jelenít meg.

Tidak ada ketergantungan tambahan yang diperlukan. + +--- + +## Cara membuat barcode databar 4‑kolom + +Langkah pertama adalah membuat instance `BarcodeGenerator` yang menargetkan simbol **DataBar Expanded Stacked**. Kelas ini mengenkapsulasi semua opsi rendering, sehingga mudah beralih antara tata letak berbasis kolom dan berbasis baris. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Mengapa ini berhasil:** +`EncodeTypes.DatabarExpandedStacked` memberi tahu Aspose.BarCode untuk menghasilkan versi stacked dari keluarga DataBar. Properti `DataBar.Columns` mengontrol berapa banyak modul vertikal yang ditempati barcode. Menetapkannya ke 4 memenuhi persyaratan untuk **membuat barcode databar 4‑kolom**. Akhirnya, `Save` menulis representasi visual ke disk menggunakan **format gambar barcode** `Png`. + +### Konfigurasi kolom DataBar Expanded Stacked + +Jika Anda memerlukan jumlah kolom yang berbeda, cukup ubah nilai integer yang diberikan ke `Columns`. Properti ini menerima nilai dari 1 hingga 4 untuk varian expanded stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro tip:* Selalu uji barcode yang dihasilkan dengan pemindai yang mendukung keluarga DataBar, karena penampilan visual saja tidak menjamin keterbacaan. + +### Simpan gambar barcode + +Enumerasi `BarCodeImageFormat` menyediakan beberapa opsi (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG bersifat loss‑less dan bekerja baik untuk kebanyakan skenario web dan desktop. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Jika Anda memerlukan format lain, ganti `Png` dengan nilai enum yang diinginkan. File yang disimpan dapat disisipkan langsung ke HTML, PDF, atau dicetak pada label. + +## Buat barcode dengan baris khusus + +Kadang-kadang tata letak stacked diperlukan dengan jumlah baris tertentu alih‑alih kolom. Kelas `BarcodeGenerator` yang sama menyediakan properti `Rows` untuk tujuan ini. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Mengapa baris penting:** +Ketika barcode stacked lebih tinggi daripada lebarnya, properti `Rows` menentukan berapa banyak irisan horizontal simbol dibagi. Menetapkan `Rows = 3` menghasilkan barcode stacked tiga baris, yang berguna untuk lebar label yang sempit. + +### Atur baris barcode secara dinamis + +Anda dapat menghitung jumlah baris pada runtime berdasarkan data masukan: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Fleksibilitas ini memungkinkan Anda **mengatur baris barcode** tanpa harus mengompilasi ulang aplikasi. + +## Contoh lengkap end‑to‑end + +Berikut adalah program tunggal yang menghasilkan baik barcode 4‑kolom maupun barcode 3‑baris, memperlihatkan cara kedua konfigurasi dapat berdampingan. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Output yang diharapkan:** +Dua file PNG muncul di direktori kerja aplikasi: + +* `DatabarCols4.png` – barcode DataBar Expanded Stacked dengan empat kolom vertikal. +* `DatabarRows3.png` – simbol yang sama diatur dalam tiga baris horizontal. + +Kedua gambar dapat dibuka di penampil gambar apa pun atau disisipkan dalam kontrol UI. + +--- + +## Pertanyaan umum dan kasus tepi + +| Question | Answer | +|----------|--------| +| *Can I use a different barcode symbology?* | Ya. Ganti `EncodeTypes.DatabarExpandedStacked` dengan nilai `EncodeTypes` lain (misalnya `EncodeTypes.QR`), tetapi properti `Columns` dan `Rows` khusus untuk keluarga DataBar. | +| *What if the data string exceeds the maximum length?* | Simbologi DataBar Expanded Stacked mendukung hingga 61 karakter numerik. Melebihi batas ini akan menimbulkan `ArgumentException`. Validasi input sebelum menetapkannya ke generator. | +| *Do I need to dispose the `BarcodeGenerator`?* | `BarcodeGenerator` mengimplementasikan `IDisposable`. Pada layanan yang berjalan lama, bungkuslah dalam blok `using` atau panggil `Dispose()` secara manual untuk membebaskan sumber daya native. | +| *Can I generate SVG instead of PNG?* | Tentu saja. Gunakan `BarCodeImageFormat.Svg` pada metode `Save`. | +| *Is the library compatible with .NET Core?* | Aspose.BarCode untuk .NET mendukung .NET Core 3.1, .NET 5, .NET 6, dan versi selanjutnya. Tidak diperlukan perubahan kode. | + +--- + +## Kesimpulan + +Anda kini tahu cara **membuat barcode databar 4‑kolom** di C# menggunakan Aspose.BarCode, cara menyesuaikan tata letak dengan baris, dan cara mengekspor hasil dalam **format gambar barcode** yang praktis. Contoh lengkap menampilkan konfigurasi berbasis kolom maupun baris, memberi Anda fondasi yang kuat untuk skenario pencetakan label atau pemindaian seluler apa pun. + +**Langkah selanjutnya** + +* Bereksperimenlah dengan payload data yang berbeda dan verifikasi kompatibilitas pemindai. +* Jelajahi opsi styling tambahan seperti warna latar depan/latar belakang (`generator.Parameters.Barcode.Color`). +* Gabungkan barcode dengan grafik lain menggunakan API `Graphics` untuk desain label khusus. + +Silakan sesuaikan kode untuk proyek ASP.NET Core, Windows Forms, atau Xamarin—Aspose.BarCode berfungsi di semua platform .NET.

Kelas ini mengenkapsulasi tipe enkoding, string data, dan semua parameter rendering. + +### Langkah 1: Tentukan folder output + +Pilih folder tempat file PNG yang dihasilkan akan disimpan. Menggunakan jalur absolut menghindari kejutan izin. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Mengapa?** Membuat folder secara programatik menjamin bahwa pemanggilan `Save` berikutnya berhasil bahkan pada mesin baru. + +### Langkah 2: Buat instance barcode generator + +Untuk barcode DataBar Omnidirectional, berikan `EncodeTypes.DatabarOmniDirectional` dan string data GS1‑128. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Catatan:** Objek `BarcodeGenerator` dapat digunakan kembali; Anda dapat mengubah parameternya di antara penyimpanan untuk **membuat beberapa barcode** dari data yang sama. + +### Langkah 3: Atur parameter barcode umum + +Penyesuaian visual yang paling umum adalah X‑dimension (lebar modul) dan tinggi bar. Keduanya dinyatakan dalam pixel. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Mengapa mengatur X‑dimension?** X‑dimension yang lebih kecil menghasilkan resolusi lebih tinggi, yang penting ketika gambar akan dicetak atau ditampilkan pada layar ber‑DPI tinggi. + +### Langkah 4: Simpan gambar barcode pertama + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +File `DatabarBarHeight30Pixels.png` kini berisi barcode DataBar Omnidirectional dengan tinggi 30 pixel. + +### Langkah 5: Sesuaikan pixel tinggi barcode + +Mengubah tinggi tidak memerlukan instance `BarcodeGenerator` baru—cukup ubah parameternya. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Langkah 6: Simpan gambar barcode kedua + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Sekarang Anda memiliki dua file PNG dengan **pixel tinggi barcode** yang berbeda, menunjukkan betapa mudahnya **membuat variasi gambar barcode**. + +## Mengatur pixel tinggi barcode secara dinamis + +Seringkali Anda membutuhkan serangkaian barcode dengan tinggi yang sesuai dengan elemen UI atau label cetak. Metode bantu berikut mengabstraksi perubahan tinggi: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Anda kini dapat memanggil `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` untuk **membuat gambar barcode** dengan tinggi 45 pixel dalam satu baris. + +## Membuat beberapa barcode dalam loop + +Ketika Anda memiliki kumpulan identifier produk, loop `foreach` menghilangkan kode berulang. Contoh ini menunjukkan cara **membuat beberapa barcode** dari array GTIN. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +Loop tersebut menghasilkan tiga file PNG, masing‑masing dengan nilai **pixel tinggi barcode** yang berbeda. Karena helper `SaveBarcodeWithHeight` mengenkapsulasi perubahan tinggi, loop utama tetap bersih dan terfokus pada data. + +### Output yang diharapkan + +Setelah menjalankan contoh lengkap, folder `Barcodes` berisi: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Membuka PNG mana pun menampilkan barcode DataBar Omnidirectional yang tajam dan dapat dipindai oleh aplikasi seluler standar. + +## Kesalahan umum dan tip pro + +| Issue | Why it happens | How to avoid it | +|-------|----------------|-----------------| +| **Wrong EncodeTypes** | Menggunakan tipe 1D untuk DataBar akan menghasilkan gambar yang tidak dapat dibaca. | Selalu pilih `EncodeTypes.DatabarOmniDirectional` (atau varian DataBar lainnya) untuk payload GS1‑128. | +| **Insufficient X‑dimension** | X‑dimension yang sangat rendah dapat membuat bar tipis menghilang pada monitor beresolusi rendah. | Pertahankan `XDimension.Pixels` ≥ 2 untuk tampilan layar; tingkatkan menjadi 3‑4 untuk pencetakan. | +| **File path errors** | Jalur relatif mungkin mengarah ke direktori yang tidak terduga. | Gunakan `Path.Combine` dan `Environment.CurrentDirectory` untuk membangun jalur absolut. | +| **Overwriting images** | Menggunakan nama file yang sama dalam loop akan menimpa hasil sebelumnya. | Sertakan identifier unik (mis., GTIN atau timestamp) dalam nama file. | +| **Missing NuGet package** | Kode berhasil dikompilasi tetapi melempar `FileNotFoundException` saat runtime. | Pastikan `Aspose.BarCode` terinstal dan proyek merujuknya. | + +## Contoh lengkap yang berfungsi + +Berikut adalah program lengkap yang dapat Anda salin ke aplikasi console.

Mengubah parameter antara panggilan `Save` lebih cepat dan menggunakan memori lebih sedikit. | +| **Validasi folder output** | Selalu panggil `Directory.CreateDirectory` sebelum menyimpan; jika tidak, `Save` akan melempar `DirectoryNotFoundException`. | +| **Pilih X‑dimension yang tepat** | Nilai pixel yang sangat rendah (mis., 1) dapat membuat barcode tidak terbaca pada layar beresolusi rendah. Nilai 2–3 bekerja baik untuk kebanyakan printer. | +| **Perhatikan encoding** | GS1 DataBar mengharapkan awalan `(01)` untuk GTIN. Jika Anda menghilangkan tanda kurung, perpustakaan dapat menghasilkan barcode yang tidak valid. | +| **Uji dengan pemindai nyata** | Inspeksi visual tidak cukup. Uji file PNG dengan perangkat pemindai sebenarnya yang akan Anda gunakan. | + +## Output yang diharapkan (deskripsi visual) + +*Kedua file PNG menampilkan barcode DataBar Stacked Omnidirectional dengan warna gelap di atas latar terang.

Ti guideremo nella generazione di un codice a barre DataBar Expanded Stacked, nella configurazione di quattro colonne e nel salvataggio del risultato come immagine PNG. + +Nel presente tutorial imparerai a: + +* Inizializzare il `BarcodeGenerator` per un simbolo **DataBar Expanded Stacked**. +* Impostare il conteggio delle colonne a 4 (requisito principale). +* Regolare il conteggio delle righe quando è necessario un layout impilato con tre righe. +* Esportare il codice a barre come PNG utilizzando il **barcode image format** appropriato. + +Hai bisogno solo della libreria Aspose.BarCode per .NET (versione 23.10 o successiva) e di un ambiente di sviluppo .NET 6+ come Visual Studio 2022. Non sono richieste dipendenze aggiuntive. + +--- + +## Come creare un codice a barre databar a 4 colonne + +Il primo passo è creare un'istanza di `BarcodeGenerator` che punti alla simbologia **DataBar Expanded Stacked**. Questa classe incapsula tutte le opzioni di rendering, rendendo semplice passare da layout basati su colonne a layout basati su righe. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Perché funziona:** +`EncodeTypes.DatabarExpandedStacked` indica ad Aspose.BarCode di produrre la versione impilata della famiglia DataBar. La proprietà `DataBar.Columns` controlla quante unità verticali occupa il codice a barre. Impostandola a 4 soddisfa il requisito di **creare un codice a barre databar a 4 colonne**. Infine, `Save` scrive la rappresentazione visiva su disco usando il **barcode image format** `Png`. + +### Configura le colonne di DataBar Expanded Stacked + +Se hai bisogno di un conteggio di colonne diverso, modifica semplicemente l'intero assegnato a `Columns`. La proprietà accetta valori da 1 a 4 per la variante expanded stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Consiglio professionale:* Testa sempre il codice a barre generato con uno scanner che supporta la famiglia DataBar, poiché l'aspetto visivo da solo non garantisce la leggibilità. + +### Salva l'immagine del codice a barre + +L'enumerazione `BarCodeImageFormat` fornisce diverse opzioni (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG è loss‑less e funziona bene nella maggior parte degli scenari web e desktop. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Se ti serve un formato diverso, sostituisci `Png` con il valore enum desiderato. Il file salvato può essere incorporato direttamente in HTML, PDF o stampato su etichette. + +## Crea un codice a barre con righe personalizzate + +A volte è necessario un layout impilato con un numero specifico di righe anziché colonne. La stessa classe `BarcodeGenerator` espone una proprietà `Rows` a questo scopo. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Perché le righe sono importanti:** +Quando il codice a barre impilato è più alto che largo, la proprietà `Rows` determina in quante sezioni orizzontali è suddiviso il simbolo. Impostare `Rows = 3` crea un codice a barre impilato a tre righe, utile per larghezze di etichetta strette. + +### Imposta dinamicamente le righe del codice a barre + +Puoi calcolare il numero di righe a runtime in base ai dati di input: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Questa flessibilità ti consente di **impostare le righe del codice a barre** senza ricompilare l'applicazione. + +## Esempio completo end‑to‑end + +Di seguito trovi un unico programma che genera sia un codice a barre a 4 colonne sia un codice a barre a 3 righe, dimostrando come le due configurazioni coesistano. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Output previsto:** +Due file PNG appaiono nella directory di lavoro dell'applicazione: + +* `DatabarCols4.png` – un codice a barre DataBar Expanded Stacked con quattro colonne verticali. +* `DatabarRows3.png` – la stessa simbologia disposta in tre righe orizzontali. + +Entrambe le immagini possono essere aperte con qualsiasi visualizzatore di immagini o incorporate in un controllo UI. + +--- + +## Domande comuni e casi particolari + +| Domanda | Risposta | +|----------|--------| +| *Posso utilizzare una simbologia di codice a barre diversa?* | Sì. Sostituisci `EncodeTypes.DatabarExpandedStacked` con un altro valore `EncodeTypes` (ad esempio `EncodeTypes.QR`), ma le proprietà `Columns` e `Rows` sono specifiche delle famiglie DataBar. | +| *Cosa succede se la stringa di dati supera la lunghezza massima?* | La simbologia DataBar Expanded Stacked supporta fino a 61 caratteri numerici. Superare questo limite genera un `ArgumentException`. Convalida l'input prima di assegnarlo al generatore. | +| *Devo rilasciare (`dispose`) il `BarcodeGenerator`?* | `BarcodeGenerator` implementa `IDisposable`. In un servizio a lungo termine, avvolgilo in un blocco `using` o chiama manualmente `Dispose()` per liberare le risorse native. | +| *Posso generare SVG invece di PNG?* | Assolutamente. Usa `BarCodeImageFormat.Svg` nel metodo `Save`. | +| *La libreria è compatibile con .NET Core?* | Aspose.BarCode per .NET supporta .NET Core 3.1, .NET 5, .NET 6 e versioni successive. Non sono necessarie modifiche al codice. | + +## Conclusione + +Ora sai come **creare un codice a barre databar a 4 colonne** in C# usando Aspose.BarCode, come regolare il layout con le righe e come esportare il risultato in un comodo **barcode image format**. L'esempio completo mostra sia le configurazioni basate su colonne sia quelle basate su righe, fornendoti una solida base per qualsiasi scenario di stampa di etichette o di scansione mobile. + +**Prossimi passi** + +* Sperimenta con diversi payload di dati e verifica la compatibilità dello scanner. +* Esplora ulteriori opzioni di stile come i colori di primo piano/sfondo (`generator.Parameters.Barcode.Color`). +* Combina il codice a barre con altre grafiche usando l'API `Graphics` per progetti di etichette personalizzate. + +Sentiti libero di adattare il codice per progetti ASP.NET Core, Windows Forms o Xamarin—Aspose.BarCode funziona su tutte le piattaforme .NET.

Entrambe sono espresse in pixel. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Perché impostare la X‑dimension?** Una X‑dimension più piccola produce una risoluzione più alta, importante quando l'immagine verrà stampata o visualizzata su schermi ad alta DPI. + +### Passo 4: Salva la prima immagine barcode + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Il file `DatabarBarHeight30Pixels.png` ora contiene un barcode DataBar Omnidirectional alto 30 pixel. + +### Passo 5: Regola i pixel di altezza del barcode + +Modificare l'altezza non richiede una nuova istanza di `BarcodeGenerator`—basta modificare il parametro. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Passo 6: Salva la seconda immagine barcode + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Ora hai due file PNG con diversi **pixel di altezza del barcode**, dimostrando quanto sia semplice creare variazioni di **immagine barcode**. + +## Impostare dinamicamente i pixel di altezza del barcode + +Spesso è necessario una serie di barcode con altezze che corrispondono a elementi UI o etichette stampate. Il metodo di supporto seguente astrae il cambiamento di altezza: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Ora puoi chiamare `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` per **creare un'immagine barcode** con un'altezza di 45 pixel in una singola riga. + +## Creare più barcode in un ciclo + +Quando hai una collezione di identificatori di prodotto, un ciclo `foreach` elimina il codice ripetitivo. Questo esempio mostra come **creare più barcode** da un array di GTIN. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +Il ciclo produce tre file PNG, ognuno con un valore distinto di **pixel di altezza del barcode**. Poiché il metodo di supporto `SaveBarcodeWithHeight` incapsula il cambiamento di altezza, il ciclo principale rimane pulito e focalizzato sui dati. + +### Output previsto + +Dopo aver eseguito l'esempio completo, la cartella `Barcodes` contiene: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Aprire qualsiasi PNG mostra un barcode DataBar Omnidirectional nitido che può essere scansionato dalle app mobili standard. + +## Problemi comuni e consigli professionali + +| Problema | Perché succede | Come evitarlo | +|----------|----------------|---------------| +| **EncodeTypes errati** | Usare un tipo 1D per un DataBar produrrà un'immagine illeggibile. | Scegli sempre `EncodeTypes.DatabarOmniDirectional` (o un'altra variante DataBar) per payload GS1‑128. | +| **X‑dimension insufficiente** | Una X‑dimension molto bassa può far scomparire le barre sottili su monitor a bassa risoluzione. | Mantieni `XDimension.Pixels` ≥ 2 per la visualizzazione su schermo; aumentala a 3‑4 per la stampa. | +| **Errori di percorso file** | I percorsi relativi possono risolversi in directory inaspettate. | Usa `Path.Combine` e `Environment.CurrentDirectory` per costruire percorsi assoluti. | +| **Sovrascrittura delle immagini** | Riutilizzare lo stesso nome file in un ciclo sovrascrive i risultati precedenti. | Includi identificatori unici (ad es., GTIN o timestamp) nel nome del file. | +| **Pacchetto NuGet mancante** | Il codice compila ma genera `FileNotFoundException` a runtime. | Verifica che `Aspose.BarCode` sia installato e che il progetto lo riferisca. | + +## Esempio completo funzionante + +Di seguito trovi il programma completo che puoi copiare in un'applicazione console.

Troverai due file PNG: + +* **DatabarAspectRatio15.png** – un barcode compatto adatto a etichette di altezza limitata. +* **DatabarAspectRatio30.png** – un barcode più alto che molti scanner leggono più affidabilmente da una distanza. + +Entrambe le immagini sono pronte per essere incorporate in PDF, stampate su ricevute o inviate a un'app mobile. + +## Passo 4: Estendi la soluzione per generare un numero qualsiasi di barcode + +Il pattern mostrato sopra scala facilmente: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **genera più barcode** – Il ciclo itera su un array di rapporti d'aspetto, creando una **immagine barcode** distinta per ogni valore. +* Regola `EncodeTypes` o la stringa codificata per produrre QR code, Code 128 o altre simbologie senza modificare la logica circostante. + +## Suggerimenti pratici e ostacoli comuni + +| Suggerimento | Spiegazione | +|-----|-------------| +| **Riutilizza lo stesso generatore** | Re‑inizializzare `BarcodeGenerator` per ogni immagine aggiunge un overhead inutile. Cambiare i parametri tra le chiamate `Save` è più veloce e utilizza meno memoria. | +| **Convalida la cartella di output** | Chiama sempre `Directory.CreateDirectory` prima di salvare; altrimenti `Save` genera una `DirectoryNotFoundException`. | +| **Scegli una X‑dimension appropriata** | Valori di pixel molto bassi (es., 1) possono rendere il barcode illeggibile su schermi a bassa risoluzione. Valori tra 2 e 3 funzionano bene per la maggior parte delle stampanti. | +| **Fai attenzione alla codifica** | GS1 DataBar si aspetta un prefisso `(01)` per il GTIN. Se ometti le parentesi, la libreria potrebbe generare un barcode non valido. | +| **Testa con uno scanner reale** | L'ispezione visiva non è sufficiente. Testa i file PNG con l'hardware scanner reale che intendi utilizzare. | + +## Output previsto (descrizione visiva) + +*Entrambi i file PNG mostrano un barcode DataBar Stacked Omnidirectional scuro su sfondo chiaro. La versione con rapporto d'aspetto 15 è più corta, mentre la versione con rapporto d'aspetto 30 è circa il doppio più alta.* + +Se incorpori le immagini in un documento, verranno renderizzate nitide perché abbiamo impostato `XDimension.Pixels = 2`. + +## Conclusione + +Ora sai come **creare file immagine barcode** usando un **generatore barcode C#**, e puoi **generare più barcode** regolando il rapporto d'aspetto o qualsiasi altro parametro.

+using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long");

+``` + +*Pro tip:* 生成されたバーコードは、DataBar ファミリーをサポートするスキャナで必ずテストしてください。視覚的な外観だけでは読み取り可能性が保証されません。 + +### バーコード画像の保存 + +`BarCodeImageFormat` 列挙体は複数のオプション（`Png`、`Jpeg`、`Bmp`、`Gif`、`Tiff`）を提供します。PNG はロスレスで、ほとんどのウェブやデスクトップシナリオでうまく機能します。 + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +別の形式が必要な場合は、`Png` を目的の列挙値に置き換えてください。保存されたファイルは HTML、PDF、またはラベルへの印刷に直接埋め込むことができます。 + +## カスタム行でバーコードを作成する + +場合によっては、列ではなく特定の行数でスタックレイアウトが必要になることがあります。同じ `BarcodeGenerator` クラスはこの目的のために `Rows` プロパティを公開しています。 + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long");

+ } +} +``` + +**行が重要な理由:** +スタックされたバーコードが幅よりも高さがある場合、`Rows` プロパティはシンボルが何個の水平スライスに分割されるかを決定します。`Rows = 3` と設定すると、3 行のスタックバーコードが作成され、狭いラベル幅に有用です。 + +### バーコード行を動的に設定する + +入力データに基づいて、実行時に行数を計算できます： + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +この柔軟性により、アプリケーションを再コンパイルせずに **バーコードの行数を設定** できます。 + +## 完全なエンドツーエンド例 + +以下は、4 列のバーコードと 3 行のバーコードの両方を生成し、2 つの構成が共存できることを示す単一プログラムです。 + +```csharp +using Aspose.BarCode.Generation;

+``` + +> **注:** `BarcodeGenerator` オブジェクトは再利用可能です。保存間でパラメータを変更することで、同じデータから **複数のバーコード** を **作成** できます。 + +### 手順 3: 共通のバーコードパラメータを設定する + +最も一般的なビジュアル調整は X‑dimension（モジュール幅）とバーの高さです。どちらもピクセル単位で指定します。 + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **なぜ X‑dimension を設定するのか？** X‑dimension を小さくすると解像度が上がり、画像を印刷したり高 DPI スクリーンに表示したりする際に重要です。 + +### 手順 4: 最初のバーコード画像を保存する + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +ファイル `DatabarBarHeight30Pixels.png` には、30 ピクセルの高さの DataBar Omnidirectional バーコードが含まれています。 + +### 手順 5: バーコードの高さ（ピクセル）を調整する + +高さを変更する際に新しい `BarcodeGenerator` インスタンスは不要です。パラメータを変更するだけです。 + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### 手順 6: 2 番目のバーコード画像を保存する + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +これで、異なる **バーコード高さ（ピクセル）** を持つ 2 つの PNG ファイルができました。**バーコード画像** のバリエーションを作成するのがいかに簡単かが示されています。 + +## バーコード高さ（ピクセル）を動的に設定する + +UI 要素や印刷ラベルに合わせた高さのバーコードが多数必要になることがよくあります。以下のヘルパーメソッドは高さの変更を抽象化します。 + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +これで、`SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` を呼び出すだけで、45 ピクセルの高さの **バーコード画像** をワンラインで **作成** できます。 + +## ループで複数のバーコードを作成する + +製品識別子のコレクションがある場合、`foreach` ループで繰り返しコードを削減できます。この例は、GTIN の配列から **複数のバーコード** を **作成** する方法を示しています。 + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +このループは 3 つの PNG ファイルを生成し、それぞれ異なる **バーコード高さ（ピクセル）** の値を持ちます。`SaveBarcodeWithHeight` ヘルパーが高さ変更をカプセル化しているため、メインループはデータに集中したシンプルな構造のままです。 + +### 期待される出力 + +サンプル全体を実行すると、`Barcodes` フォルダーには以下が含まれます： + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +任意の PNG を開くと、標準的なモバイルアプリでスキャン可能な鮮明な DataBar Omnidirectional バーコードが表示されます。 + +## よくある落とし穴とプロのコツ + +| Issue | Why it happens | How to avoid it | +|-------|----------------|-----------------| +| **EncodeTypes の誤り** | DataBar に 1D タイプを使用すると、読めない画像が生成されます。 | `EncodeTypes.DatabarOmniDirectional`（または他の DataBar バリアント）を GS1‑128 ペイロードに必ず使用してください。 | +| **X‑dimension が不足** | 非常に低い X‑dimension は、低解像度モニターで細いバーが消えてしまう可能性があります。 | `XDimension.Pixels` を画面表示では ≥ 2、印刷では 3‑4 に保ちます。 | +| **ファイルパスエラー** | 相対パスは予期しないディレクトリに解決されることがあります。 | `Path.Combine` と `Environment.CurrentDirectory` を使用して絶対パスを構築します。 | +| **画像の上書き** | ループ内で同じファイル名を再利用すると、以前の結果が上書きされます。 | ファイル名にユニークな識別子（例: GTIN やタイムスタンプ）を含めます。 | +| **NuGet パッケージが欠如** | コードはコンパイルされますが、実行時に `FileNotFoundException` がスローされます。 | `Aspose.BarCode` がインストールされ、プロジェクトが参照していることを確認してください。 | + +## 完全な動作例 + +以下はコンソールアプリケーションにコピーできる完全なプログラムです。すべての手順、ヘルパーメソッド、エラーハンドリングが含まれています。 + +```csharp +using System;

Nie są wymagane dodatkowe zależności. + +--- + +## Jak utworzyć 4‑kolumnowy kod kreskowy DataBar + +Pierwszym krokiem jest utworzenie instancji `BarcodeGenerator`, która obsługuje symbologię **DataBar Expanded Stacked**. Ta klasa kapsułkuje wszystkie opcje renderowania, co ułatwia przełączanie się między układami opartymi na kolumnach a układami opartymi na wierszach. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Dlaczego to działa:** +`EncodeTypes.DatabarExpandedStacked` informuje Aspose.BarCode, aby wygenerował wersję układaną (stacked) rodziny DataBar. Właściwość `DataBar.Columns` kontroluje, ile pionowych modułów zajmuje kod kreskowy. Ustawienie jej na 4 spełnia wymóg **utworzenia 4‑kolumnowego kodu kreskowego DataBar**. Na koniec, `Save` zapisuje wizualną reprezentację na dysk przy użyciu **formatu obrazu kodu kreskowego** `Png`. + +### Konfiguracja kolumn DataBar Expanded Stacked + +Jeśli potrzebujesz innej liczby kolumn, po prostu zmień liczbę całkowitą przypisaną do `Columns`. Właściwość akceptuje wartości od 1 do 4 dla wariantu Expanded Stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Wskazówka:* Zawsze testuj wygenerowany kod kreskowy przy użyciu skanera obsługującego rodzinę DataBar, ponieważ sam wygląd wizualny nie gwarantuje czytelności. + +### Zapisz obraz kodu kreskowego + +Wyliczenie `BarCodeImageFormat` oferuje kilka opcji (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG jest bezstratny i dobrze sprawdza się w większości scenariuszy webowych i desktopowych. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Jeśli potrzebujesz innego formatu, zamień `Png` na żądaną wartość wyliczenia. Zapisany plik może być osadzony bezpośrednio w HTML, PDF‑ach lub wydrukowany na etykietach. + +## Utwórz kod kreskowy z niestandardowymi wierszami + +Czasami potrzebny jest układ stosowany (stacked) z określoną liczbą wierszy zamiast kolumn. Ta sama klasa `BarcodeGenerator` udostępnia właściwość `Rows` w tym celu. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Dlaczego wiersze mają znaczenie:** +Gdy kod kreskowy w układzie stacked jest wyższy niż szerszy, właściwość `Rows` określa, na ile poziomych części podzielony jest symbol. Ustawienie `Rows = 3` tworzy trzy‑wierszowy kod kreskowy stacked, co jest przydatne przy wąskich szerokościach etykiet. + +### Ustaw wiersze kodu kreskowego dynamicznie + +Możesz obliczyć liczbę wierszy w czasie wykonywania na podstawie danych wejściowych: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Ta elastyczność pozwala **ustawić wiersze kodu kreskowego** bez konieczności rekompilacji aplikacji. + +## Pełny przykład end‑to‑end + +Poniżej znajduje się pojedynczy program, który generuje zarówno kod kreskowy 4‑kolumnowy, jak i 3‑wierszowy, demonstrując, jak obie konfiguracje mogą współistnieć. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Oczekiwany wynik:** +Dwa pliki PNG pojawiają się w katalogu roboczym aplikacji: + +* `DatabarCols4.png` – kod kreskowy DataBar Expanded Stacked z czterema pionowymi kolumnami. +* `DatabarRows3.png` – ta sama symbologia ułożona w trzy poziome wiersze. + +Oba obrazy można otworzyć w dowolnym przeglądarce obrazów lub osadzić w kontrolce UI. + +--- + +## Częste pytania i przypadki brzegowe + +| Question | Answer | +|----------|--------| +| *Czy mogę użyć innej symbologii kodu kreskowego?* | Tak. Zastąp `EncodeTypes.DatabarExpandedStacked` inną wartością `EncodeTypes` (np. `EncodeTypes.QR`), ale właściwości `Columns` i `Rows` są specyficzne dla rodzin DataBar. | +| *Co jeśli ciąg danych przekracza maksymalną długość?* | Symbologia DataBar Expanded Stacked obsługuje maksymalnie 61 znaków numerycznych. Przekroczenie tego limitu powoduje wyrzucenie `ArgumentException`. Zweryfikuj dane wejściowe przed przypisaniem ich do generatora. | +| *Czy muszę zwolnić zasoby `BarcodeGenerator`?* | `BarcodeGenerator` implementuje `IDisposable`. W długotrwałej usłudze, otocz go blokiem `using` lub wywołaj `Dispose()` ręcznie, aby zwolnić zasoby natywne. | +| *Czy mogę generować SVG zamiast PNG?* | Oczywiście. Użyj `BarCodeImageFormat.Svg` w metodzie `Save`. | +| *Czy biblioteka jest kompatybilna z .NET Core?* | Aspose.BarCode for .NET obsługuje .NET Core 3.1, .NET 5, .NET 6 i nowsze. Nie są wymagane zmiany w kodzie. | + +## Podsumowanie + +Teraz wiesz, jak **utworzyć 4‑kolumnowy kod kreskowy DataBar** w C# przy użyciu Aspose.BarCode, jak dostosować układ przy użyciu wierszy oraz jak wyeksportować wynik w wygodnym **formacie obrazu kodu kreskowego**.

Zawiera ona typ kodowania, ciąg danych oraz wszystkie parametry renderowania. + +### Krok 1: Zdefiniuj folder wyjściowy + +Wybierz folder, w którym będą przechowywane wygenerowane pliki PNG. Użycie ścieżki bezwzględnej zapobiega niespodziewanym problemom z uprawnieniami. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Dlaczego?** Tworzenie folderu programowo zapewnia, że kolejne wywołania `Save` zakończą się sukcesem nawet na nowej maszynie. + +### Krok 2: Utwórz generator kodu kreskowego + +Dla kodu DataBar Omnidirectional przekaż `EncodeTypes.DatabarOmniDirectional` oraz ciąg danych GS1‑128. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Uwaga:** Obiekt `BarcodeGenerator` jest wielokrotnego użytku; możesz zmieniać jego parametry pomiędzy zapisami, aby **tworzyć wiele kodów kreskowych** z tych samych danych. + +### Krok 3: Ustaw wspólne parametry kodu kreskowego + +Najczęstsze korekty wizualne to wymiar X (szerokość modułu) oraz wysokość kreski. Oba podawane są w pikselach. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Dlaczego ustawiać wymiar X?** Mniejszy wymiar X daje wyższą rozdzielczość, co jest istotne, gdy obraz będzie drukowany lub wyświetlany na ekranach o wysokiej gęstości DPI. + +### Krok 4: Zapisz pierwszy obraz kodu kreskowego + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Plik `DatabarBarHeight30Pixels.png` zawiera teraz DataBar Omnidirectional o wysokości 30 pikseli. + +### Krok 5: Dostosuj wysokość kodu kreskowego w pikselach + +Zmiana wysokości nie wymaga nowej instancji `BarcodeGenerator` — wystarczy zmodyfikować parametr. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Krok 6: Zapisz drugi obraz kodu kreskowego + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Teraz masz dwa pliki PNG z różnymi **wysokościami kodu kreskowego w pikselach**, co pokazuje, jak łatwo jest **tworzyć różne obrazy kodu kreskowego**. + +## Ustawianie wysokości kodu kreskowego w pikselach dynamicznie + +Często potrzebna jest seria kodów kreskowych o wysokościach dopasowanych do elementów UI lub etykiet drukowanych. Poniższa metoda pomocnicza abstrahuje zmianę wysokości: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Możesz teraz wywołać `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");`, aby **utworzyć obraz kodu kreskowego** o wysokości 45 pikseli w jednej linii. + +## Tworzenie wielu kodów kreskowych w pętli + +Gdy masz kolekcję identyfikatorów produktów, pętla `foreach` eliminuje powtarzalny kod. Ten przykład pokazuje, jak **tworzyć wiele kodów kreskowych** z tablicy GTIN‑ów. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +Pętla generuje trzy pliki PNG, każdy z inną wartością **wysokości kodu kreskowego w pikselach**. Ponieważ metoda pomocnicza `SaveBarcodeWithHeight` kapsułkuje zmianę wysokości, główna pętla pozostaje czysta i skoncentrowana na danych. + +### Oczekiwany wynik + +Po uruchomieniu pełnego przykładu folder `Barcodes` zawiera: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Otworzenie dowolnego pliku PNG pokazuje wyraźny kod DataBar Omnidirectional, który może być zeskanowany przez standardowe aplikacje mobilne. + +## Częste pułapki i wskazówki profesjonalne + +| Problem | Dlaczego się pojawia | Jak tego uniknąć | +|-------|----------------|-----------------| +| **Nieprawidłowe EncodeTypes** | Użycie typu 1D dla DataBar spowoduje nieczytelny obraz. | Zawsze wybieraj `EncodeTypes.DatabarOmniDirectional` (lub inną odmianę DataBar) dla ładunków GS1‑128. | +| **Niewystarczający wymiar X** | Bardzo mały wymiar X może spowodować znikanie cienkich pasków na monitorach o niskiej rozdzielczości. | Utrzymuj `XDimension.Pixels` ≥ 2 dla wyświetlania na ekranie; zwiększ do 3‑4 przy drukowaniu. | +| **Błędy ścieżki pliku** | Ścieżki względne mogą rozwiązywać się do nieoczekiwanych katalogów. | Używaj `Path.Combine` i `Environment.CurrentDirectory` do budowania ścieżek bezwzględnych. | +| **Nadpisywanie obrazów** | Ponowne użycie tej samej nazwy pliku w pętli nadpisuje poprzednie wyniki. | Dodawaj unikalne identyfikatory (np.

Vamos percorrer a geração de um código de barras DataBar Expanded Stacked, configurando quatro colunas e salvando o resultado como uma imagem PNG. + +Neste guia você aprenderá como: + +* Inicializar o `BarcodeGenerator` para um símbolo **DataBar Expanded Stacked**. +* Definir a contagem de colunas para 4 (o requisito principal). +* Ajustar a contagem de linhas quando precisar de um layout empilhado com três linhas. +* Exportar o código de barras como PNG usando o **formato de imagem de código de barras** apropriado. + +Você só precisa da biblioteca Aspose.BarCode for .NET (versão 23.10 ou posterior) e de um ambiente de desenvolvimento .NET 6+ como o Visual Studio 2022. Nenhuma dependência adicional é necessária. + +--- + +## Como criar código de barras databar de 4 colunas + +O primeiro passo é criar uma instância de `BarcodeGenerator` que tenha como alvo a simbologia **DataBar Expanded Stacked**. Esta classe encapsula todas as opções de renderização, facilitando a troca entre layouts baseados em colunas e em linhas. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Por que isso funciona:** +`EncodeTypes.DatabarExpandedStacked` indica ao Aspose.BarCode que produza a versão empilhada da família DataBar. A propriedade `DataBar.Columns` controla quantos módulos verticais o código de barras ocupa. Definir isso para 4 corresponde ao requisito de **criar um código de barras databar de 4 colunas**. Por fim, `Save` grava a representação visual no disco usando o **formato de imagem de código de barras** `Png`. + +### Configurar colunas do DataBar Expanded Stacked + +Se você precisar de uma contagem de colunas diferente, basta alterar o número inteiro atribuído a `Columns`. A propriedade aceita valores de 1 a 4 para a variante expanded stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Dica profissional:* Sempre teste o código de barras gerado com um scanner que suporte a família DataBar, pois a aparência visual sozinha não garante a legibilidade. + +### Salvar a imagem do código de barras + +A enumeração `BarCodeImageFormat` oferece várias opções (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG é sem perdas e funciona bem na maioria dos cenários web e desktop. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Se você precisar de um formato diferente, substitua `Png` pelo valor de enum desejado. O arquivo salvo pode ser incorporado diretamente em HTML, PDFs ou impresso em etiquetas. + +## Criar um código de barras com linhas personalizadas + +Às vezes, um layout empilhado é necessário com um número específico de linhas em vez de colunas. A mesma classe `BarcodeGenerator` expõe uma propriedade `Rows` para esse propósito. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Por que as linhas são importantes:** +Quando o código de barras empilhado é mais alto que largo, a propriedade `Rows` determina em quantas fatias horizontais o símbolo será dividido. Definir `Rows = 3` cria um código de barras empilhado de três linhas, útil para larguras estreitas de etiqueta. + +### Definir linhas do código de barras dinamicamente + +Você pode calcular a contagem de linhas em tempo de execução com base nos dados de entrada: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Essa flexibilidade permite que você **defina linhas do código de barras** sem recompilar a aplicação. + +## Exemplo completo de ponta a ponta + +A seguir, um programa único que gera tanto um código de barras de 4 colunas quanto um de 3 linhas, demonstrando como as duas configurações coexistem. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Saída esperada:** +Dois arquivos PNG aparecem no diretório de trabalho da aplicação: + +* `DatabarCols4.png` – um código de barras DataBar Expanded Stacked com quatro colunas verticais. +* `DatabarRows3.png` – a mesma simbologia organizada em três linhas horizontais. + +Ambas as imagens podem ser abertas em qualquer visualizador de imagens ou incorporadas em um controle de UI. + +--- + +## Perguntas comuns e casos de borda + +| Pergunta | Resposta | +|----------|----------| +| *Posso usar uma simbologia de código de barras diferente?* | Sim. Substitua `EncodeTypes.DatabarExpandedStacked` por outro valor de `EncodeTypes` (por exemplo, `EncodeTypes.QR`), mas as propriedades `Columns` e `Rows` são específicas das famílias DataBar. | +| *E se a string de dados exceder o comprimento máximo?* | A simbologia DataBar Expanded Stacked suporta até 61 caracteres numéricos. Exceder esse limite lança uma `ArgumentException`. Valide a entrada antes de atribuí‑la ao gerador. | +| *Preciso descartar o `BarcodeGenerator`?* | `BarcodeGenerator` implementa `IDisposable`. Em um serviço de longa duração, envolva‑o em um bloco `using` ou chame `Dispose()` manualmente para liberar recursos nativos. | +| *Posso gerar SVG em vez de PNG?* | Absolutamente. Use `BarCodeImageFormat.Svg` no método `Save`. | +| *A biblioteca é compatível com .NET Core?* | Aspose.BarCode for .NET suporta .NET Core 3.1, .NET 5, .NET 6 e posteriores. Nenhuma alteração de código é necessária. | + +## Conclusão + +Agora você sabe como **criar um código de barras databar de 4 colunas** em C# usando Aspose.BarCode, como ajustar o layout com linhas e como exportar o resultado em um conveniente **formato de imagem de código de barras**. O exemplo completo mostra tanto configurações baseadas em colunas quanto em linhas, proporcionando uma base sólida para qualquer cenário de impressão de etiquetas ou digitalização móvel. + +**Próximos passos** + +* Experimente diferentes cargas de dados e verifique a compatibilidade com scanners. +* Explore opções adicionais de estilo, como cores de primeiro plano/fundo (`generator.Parameters.Barcode.Color`). +* Combine o código de barras com outros gráficos usando a API `Graphics` para designs de etiquetas personalizados. + +Sinta‑se à vontade para adaptar o código para projetos ASP.NET Core, Windows Forms ou Xamarin — Aspose.BarCode funciona em todas as plataformas .NET.

Ela encapsula o tipo de codificação, a string de dados e todos os parâmetros de renderização. + +### Etapa 1: Definir a pasta de saída + +Escolha uma pasta onde os arquivos PNG gerados serão armazenados. Usar um caminho absoluto evita surpresas de permissão. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Por quê?** Criar a pasta programaticamente garante que as chamadas subsequentes de `Save` sejam bem‑sucedidas mesmo em uma máquina nova. + +### Etapa 2: Instanciar o gerador de código de barras + +Para um código de barras DataBar Omnidirectional, passe `EncodeTypes.DatabarOmniDirectional` e a string de dados GS1‑128. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Nota:** O objeto `BarcodeGenerator` é reutilizável; você pode alterar seus parâmetros entre salvamentos para **criar múltiplos códigos de barras** a partir dos mesmos dados. + +### Etapa 3: Definir parâmetros comuns do código de barras + +Os ajustes visuais mais comuns são a X‑dimension (largura do módulo) e a altura da barra. Ambos são expressos em pixels. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Por que definir X‑dimension?** Uma X‑dimension menor produz maior resolução, o que é importante quando a imagem será impressa ou exibida em telas de alta DPI. + +### Etapa 4: Salvar a primeira imagem de código de barras + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +O arquivo `DatabarBarHeight30Pixels.png` agora contém um código de barras DataBar Omnidirectional com 30 pixels de altura. + +### Etapa 5: Ajustar os pixels de altura do código de barras + +Alterar a altura não requer uma nova instância de `BarcodeGenerator`—basta modificar o parâmetro. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Etapa 6: Salvar a segunda imagem de código de barras + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Agora você tem dois arquivos PNG com diferentes **pixels de altura do código de barras**, demonstrando como é fácil criar variações de **imagem de código de barras**. + +## Definindo pixels de altura do código de barras dinamicamente + +Frequentemente você precisa de uma série de códigos de barras com alturas que correspondam a elementos de UI ou etiquetas impressas. O método auxiliar a seguir abstrai a mudança de altura: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Agora você pode chamar `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` para **criar imagem de código de barras** com altura de 45 pixels em uma única linha. + +## Criando múltiplos códigos de barras em um loop + +Quando você tem uma coleção de identificadores de produto, um loop `foreach` elimina código repetitivo. Este exemplo mostra como **criar múltiplos códigos de barras** a partir de um array de GTINs. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +O loop produz três arquivos PNG, cada um com um valor distinto de **pixels de altura do código de barras**. Como o auxiliar `SaveBarcodeWithHeight` encapsula a mudança de altura, o loop principal permanece limpo e focado nos dados. + +### Saída esperada + +Após executar o exemplo completo, a pasta `Barcodes` contém: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Abrir qualquer PNG mostra um código de barras DataBar Omnidirectional nítido que pode ser escaneado por aplicativos móveis padrão. + +## Armadilhas comuns e dicas avançadas + +| Problema | Por que acontece | Como evitar | +|----------|------------------|--------------| +| **EncodeTypes errado** | Usar um tipo 1D para um DataBar produzirá uma imagem ilegível. | Sempre escolha `EncodeTypes.DatabarOmniDirectional` (ou outra variante DataBar) para cargas úteis GS1‑128. | +| **X‑dimension insuficiente** | X‑dimension muito baixa pode fazer as barras finas desaparecerem em monitores de baixa resolução. | Mantenha `XDimension.Pixels` ≥ 2 para exibição em tela; aumente para 3‑4 para impressão. | +| **Erros de caminho de arquivo** | Caminhos relativos podem resolver para diretórios inesperados. | Use `Path.Combine` e `Environment.CurrentDirectory` para construir caminhos absolutos. | +| **Sobrescrita de imagens** | Reutilizar o mesmo nome de arquivo em um loop sobrescreve resultados anteriores. | Inclua identificadores únicos (ex.: GTIN ou timestamp) no nome do arquivo. | +| **Pacote NuGet ausente** | O código compila mas lança `FileNotFoundException` em tempo de execução. | Verifique se `Aspose.BarCode` está instalado e o projeto o referencia. | + +## Exemplo completo em funcionamento + +Abaixo está o programa completo que você pode copiar para uma aplicação console.

Você encontrará dois arquivos PNG: + +* **DatabarAspectRatio15.png** – um código de barras compacto adequado para etiquetas de altura limitada. +* **DatabarAspectRatio30.png** – um código de barras mais alto que muitos scanners leem de forma mais confiável à distância. + +Ambas as imagens estão prontas para serem incorporadas em PDFs, impressas em recibos ou enviadas para um aplicativo móvel. + +## Passo 4: Estender a solução para gerar qualquer número de códigos de barras + +O padrão mostrado acima escala facilmente: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – O loop itera sobre um array de proporções, criando uma **imagem de código de barras** distinta para cada valor. +* Ajuste o `EncodeTypes` ou a string codificada para gerar QR codes, Code 128 ou outras simbologias sem alterar a lógica circundante. + +## Dicas práticas e armadilhas comuns + +| Tip | Explanation | +|-----|-------------| +| **Reutilizar o mesmo gerador** | Reinicializar o `BarcodeGenerator` para cada imagem adiciona sobrecarga desnecessária. Alterar os parâmetros entre chamadas de `Save` é mais rápido e consome menos memória. | +| **Validar a pasta de saída** | Sempre chame `Directory.CreateDirectory` antes de salvar; caso contrário, `Save` lança uma `DirectoryNotFoundException`. | +| **Escolher uma X‑dimension apropriada** | Valores de pixel muito baixos (ex.: 1) podem tornar o código de barras ilegível em telas de baixa resolução. Valores entre 2 e 3 funcionam bem na maioria das impressoras. | +| **Prestar atenção à codificação** | O GS1 DataBar espera um prefixo `(01)` para GTIN. Se você omitir os parênteses, a biblioteca pode gerar um código de barras inválido. | +| **Testar com um scanner real** | A inspeção visual não é suficiente. Teste os arquivos PNG com o hardware de scanner real que você pretende usar. | + +## Saída esperada (descrição visual) + +*Ambos os arquivos PNG exibem um código de barras DataBar Stacked Omnidirectional escuro sobre fundo claro. A versão com proporção 15 é mais curta, enquanto a versão com proporção 30 é aproximadamente duas vezes mais alta.* + +Se você incorporar as imagens em um documento, elas serão renderizadas nítidas porque definimos `XDimension.Pixels = 2`. + +## Conclusão + +Agora você sabe como **criar arquivos de imagem de código de barras** usando um **gerador de código de barras C#**, e pode **gerar múltiplos códigos de barras** ajustando a proporção ou qualquer outro parâmetro. O exemplo completo e executável demonstra boas práticas, como reutilizar a instância do gerador, lidar com diretórios de saída e verificar a criação dos arquivos. + +Em seguida, você pode explorar: + +* Adicionar cores personalizadas com `generator.Parameters.Barcode.Color` (palavra‑chave secundária: **c# barcode generator**) +* Exportar para outros formatos como JPEG ou SVG (`BarCodeImageFormat.Jpeg`, `BarCodeImageFormat.Svg`) +* Integrar a lógica de criação de códigos de barras em uma Web API para servir imagens sob demanda (palavra‑chave secundária + +## O que você deve aprender a seguir? + +Os tutoriais a seguir abordam tópicos estreitamente relacionados que se baseiam nas técnicas demonstradas neste guia.

Мы пройдем процесс генерации штрих‑кода DataBar Expanded Stacked, настройки четырёх колонок и сохранения результата в виде PNG‑изображения. + +В этом руководстве вы узнаете, как: + +* Инициализировать `BarcodeGenerator` для символа **DataBar Expanded Stacked**. +* Установить количество колонок равным 4 (основное требование). +* Настроить количество строк, когда нужен стековый макет с тремя строками. +* Экспортировать штрих‑код в PNG, используя соответствующий **barcode image format**. + +Вам понадобится только библиотека Aspose.BarCode for .NET (версии 23.10 или новее) и среда разработки .NET 6+ вроде Visual Studio 2022. Дополнительные зависимости не требуются. + +--- + +## Как создать 4‑колоночный штрих‑код DataBar + +Первый шаг — создать экземпляр `BarcodeGenerator`, который использует символьную схему **DataBar Expanded Stacked**. Этот класс инкапсулирует все параметры рендеринга, что упрощает переключение между макетами на основе колонок и строк. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Почему это работает:** +`EncodeTypes.DatabarExpandedStacked` указывает Aspose.BarCode генерировать стековую версию семейства DataBar. Свойство `DataBar.Columns` определяет, сколько вертикальных модулей занимает штрих‑код. Установка значения 4 соответствует требованию **создать 4‑колоночный штрих‑код DataBar**. Наконец, `Save` сохраняет визуальное представление на диск, используя **barcode image format** `Png`. + +### Настройка колонок DataBar Expanded Stacked + +Если требуется другое количество колонок, просто измените целое число, присвоенное `Columns`. Свойство принимает значения от 1 до 4 для варианта expanded stacked. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro tip:* Всегда проверяйте сгенерированный штрих‑код сканером, поддерживающим семейство DataBar, так как только визуальный вид не гарантирует читаемость. + +### Сохранение изображения штрих‑кода + +Перечисление `BarCodeImageFormat` предоставляет несколько вариантов (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG — без потерь и хорошо подходит для большинства веб‑ и десктоп‑сценариев. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Если нужен другой формат, замените `Png` на требуемое значение перечисления. Сохранённый файл можно напрямую встраивать в HTML, PDF или печатать на этикетках. + +## Создание штрих‑кода с пользовательскими строками + +Иногда требуется стековый макет с определённым количеством строк вместо колонок. Класс `BarcodeGenerator` предоставляет свойство `Rows` для этой цели. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Почему строки важны:** +Когда стековый штрих‑код выше, чем шире, свойство `Rows` определяет, на сколько горизонтальных секций делится символ. Установка `Rows = 3` создаёт трехстрочный стековый штрих‑код, что полезно для узких этикеток. + +### Динамическая установка строк штрих‑кода + +Вы можете вычислять количество строк во время выполнения на основе входных данных: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Эта гибкость позволяет **устанавливать строки штрих‑кода** без перекомпиляции приложения. + +## Полный сквозной пример + +Ниже представлен один пример программы, который генерирует как 4‑колоночный штрих‑код, так и 3‑строчный, демонстрируя, как обе конфигурации могут сосуществовать. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Ожидаемый результат:** +В рабочем каталоге приложения появятся два PNG‑файла: + +* `DatabarCols4.png` – штрих‑код DataBar Expanded Stacked с четырьмя вертикальными колонками. +* `DatabarRows3.png` – тот же символ, расположенный в три горизонтальные строки. + +Оба изображения можно открыть в любом просмотрщике изображений или встроить в элемент управления UI. + +--- + +## Часто задаваемые вопросы и особые случаи + +| Вопрос | Ответ | +|----------|--------| +| *Можно ли использовать другую символьную схему штрих‑кода?* | Да. Замените `EncodeTypes.DatabarExpandedStacked` другим значением `EncodeTypes` (например, `EncodeTypes.QR`), однако свойства `Columns` и `Rows` специфичны для семейств DataBar. | +| *Что делать, если строка данных превышает максимальную длину?* | Символьная схема DataBar Expanded Stacked поддерживает до 61 числового символа. Превышение этого лимита вызывает `ArgumentException`. Проверьте входные данные перед передачей их генератору. | +| *Нужно ли освобождать `BarcodeGenerator`?* | `BarcodeGenerator` реализует `IDisposable`. В длительно работающем сервисе оберните его в блок `using` или вызовите `Dispose()` вручную, чтобы освободить нативные ресурсы. | +| *Можно ли генерировать SVG вместо PNG?* | Конечно. Используйте `BarCodeImageFormat.Svg` в методе `Save`. | +| *Совместима ли библиотека с .NET Core?* | Aspose.BarCode for .NET поддерживает .NET Core 3.1, .NET 5, .NET 6 и более новые версии. Изменения кода не требуются. | + +## Заключение + +Теперь вы знаете, как **создать 4‑колоночный штрих‑код DataBar** в C# с помощью Aspose.BarCode, как настроить макет с помощью строк и как экспортировать результат в удобный **barcode image format**. Полный пример демонстрирует как конфигурацию на основе колонок, так и на основе строк, предоставляя прочную основу для любых сценариев печати этикеток или мобильного сканирования. + +**Следующие шаги** + +* Экспериментировать с различными данными и проверять совместимость со сканером. +* Исследовать дополнительные параметры оформления, такие как цвета переднего/фонового плана (`generator.Parameters.Barcode.Color`). +* Комбинировать штрих‑код с другими графическими элементами, используя API `Graphics` для создания пользовательских дизайнов этикеток. + +Не стесняйтесь адаптировать код для проектов ASP.NET Core, Windows Forms или Xamarin — Aspose.BarCode работает на всех платформах .NET.

Вы увидите, как управлять **пикселями высоты штрих‑кода**, сохранять изображение и создавать **несколько штрих‑кодов** без дублирования кода. + +В руководстве рассматривается всё — от установки пакета до настройки размеров, так что вы можете скопировать‑вставить готовый пример, готовый к запуску, в свой проект уже сегодня. + +## Предварительные требования + +* .NET 6.0 SDK или более поздняя версия, установленная +* Visual Studio 2022 (или любой IDE для C#) +* Пакет NuGet `Aspose.BarCode` – установить с помощью + +```bash +dotnet add package Aspose.BarCode +``` + +Дополнительные зависимости не требуются. + +## Как сгенерировать изображение штрих‑кода с помощью BarcodeGenerator C# + +Основным классом для создания изображения штрих‑кода является `BarcodeGenerator`. Он инкапсулирует тип кодирования, строку данных и все параметры рендеринга. + +### Шаг 1: Определите папку вывода + +Выберите папку, в которой будут сохраняться сгенерированные PNG‑файлы. Использование абсолютного пути избавляет от неожиданностей с правами доступа. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Почему?** Программное создание папки гарантирует, что последующие вызовы `Save` будут успешными даже на чистой машине. + +### Шаг 2: Создайте экземпляр генератора штрих‑кода + +Для штрих‑кода DataBar Omnidirectional передайте `EncodeTypes.DatabarOmniDirectional` и строку данных GS1‑128. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Примечание:** Объект `BarcodeGenerator` можно переиспользовать; вы можете менять его параметры между сохранениями, чтобы **создавать несколько штрих‑кодов** из одних и тех же данных. + +### Шаг 3: Установите общие параметры штрих‑кода + +Самыми распространёнными визуальными настройками являются X‑размер (ширина модуля) и высота штриха. Оба параметра задаются в пикселях. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Зачем задавать X‑размер?** Меньший X‑размер дает более высокое разрешение, что важно, когда изображение будет печататься или отображаться на экранах с высоким DPI. + +### Шаг 4: Сохраните первое изображение штрих‑кода + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Файл `DatabarBarHeight30Pixels.png` теперь содержит DataBar Omnidirectional штрих‑код высотой 30 пикселей. + +### Шаг 5: Измените высоту штрих‑кода в пикселях + +Изменение высоты не требует создания нового экземпляра `BarcodeGenerator` — достаточно изменить параметр. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Шаг 6: Сохраните второе изображение штрих‑кода + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Теперь у вас есть два PNG‑файла с разными **пикселями высоты штрих‑кода**, демонстрирующие, насколько просто создавать варианты **изображения штрих‑кода**. + +## Динамическая установка высоты штрих‑кода в пикселях + +Часто требуется серия штрих‑кодов с высотой, соответствующей элементам UI или печатным этикеткам. Ниже приведён вспомогательный метод, абстрагирующий изменение высоты: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Теперь вы можете вызвать `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");`, чтобы **создать изображение штрих‑кода** высотой 45 пикселей одной строкой. + +## Создание нескольких штрих‑кодов в цикле + +Когда у вас есть коллекция идентификаторов продуктов, цикл `foreach` устраняет повторяющийся код. Этот пример показывает, как **создавать несколько штрих‑кодов** из массива GTIN. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +Цикл создаёт три PNG‑файла, каждый с отдельным значением **пикселей высоты штрих‑кода**. Поскольку вспомогательный метод `SaveBarcodeWithHeight` инкапсулирует изменение высоты, основной цикл остаётся чистым и сосредоточенным на данных. + +### Ожидаемый результат + +После выполнения полного примера в папке `Barcodes` будет: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Открытие любого PNG‑файла покажет чёткий DataBar Omnidirectional штрих‑код, который может быть считан стандартными мобильными приложениями. + +## Распространённые ошибки и профессиональные советы + +| Проблема | Почему происходит | Как избежать | +|----------|-------------------|--------------| +| **Неправильные EncodeTypes** | Использование 1D‑типа для DataBar приводит к нечитаемому изображению. | Всегда выбирайте `EncodeTypes.DatabarOmniDirectional` (или другую вариацию DataBar) для полезных данных GS1‑128. | +| **Недостаточный X‑dimension** | Очень маленький X‑dimension может привести к исчезновению тонких штрихов на мониторах с низким разрешением. | Держите `XDimension.Pixels` ≥ 2 для отображения на экране; увеличьте до 3‑4 для печати. | +| **Ошибки пути к файлу** | Относительные пути могут разрешаться в неожиданные каталоги. | Используйте `Path.Combine` и `Environment.CurrentDirectory` для построения абсолютных путей. | +| **Перезапись изображений** | Повторное использование одного и того же имени файла в цикле перезаписывает предыдущие результаты. | Включайте уникальные идентификаторы (например, GTIN или метку времени) в имя файла. | +| **Отсутствующий пакет NuGet** | Код компилируется, но во время выполнения бросает `FileNotFoundException`. | Убедитесь, что `Aspose.BarCode` установлен и проект ссылается на него. | + +## Полный рабочий пример + +Ниже представлен полный код программы, который вы можете скопировать в консольное приложение.

Изменение параметров между вызовами `Save` быстрее и требует меньше памяти. | +| **Validate the output folder** | Всегда вызывайте `Directory.CreateDirectory` перед сохранением; иначе `Save` бросит `DirectoryNotFoundException`. | +| **Choose an appropriate X‑dimension** | Очень низкие пиксельные значения (например, 1) могут сделать штрихкод нечитаемым на экранах с низким разрешением. Значения 2–3 хорошо работают для большинства принтеров. | +| **Mind the encoding** | GS1 DataBar ожидает ведущий `(01)` для GTIN. Если опустить скобки, библиотека может сгенерировать недействительный штрихкод. | +| **Test with a real scanner** | Визуальная проверка недостаточна. Тестируйте PNG‑файлы на реальном сканере, который планируете использовать. | + +## Expected output (visual description) + +*Оба PNG‑файла показывают темный на светлом DataBar Stacked Omnidirectional штрихкод.

PNG es sin pérdida y funciona bien para la mayoría de los escenarios web y de escritorio. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Si necesitas un formato diferente, reemplaza `Png` por el valor de enumeración deseado. El archivo guardado puede incrustarse directamente en HTML, PDFs o imprimirse en etiquetas. + +## Crear un código de barras con filas personalizadas + +A veces se requiere un diseño apilado con un número específico de filas en lugar de columnas. La misma clase `BarcodeGenerator` expone una propiedad `Rows` para este propósito. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Por qué importan las filas:** +Cuando el código de barras apilado es más alto que ancho, la propiedad `Rows` determina cuántas secciones horizontales divide el símbolo. Establecer `Rows = 3` crea un código de barras apilado de tres filas, lo que es útil para etiquetas de ancho estrecho. + +### Establecer filas del código de barras dinámicamente + +Puedes calcular el número de filas en tiempo de ejecución según los datos de entrada: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Esta flexibilidad te permite **establecer filas del código de barras** sin recompilar la aplicación. + +## Ejemplo completo de extremo a extremo + +A continuación se muestra un programa único que genera tanto un código de barras de 4 columnas como uno de 3 filas, demostrando cómo coexisten ambas configuraciones. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Salida esperada:** +Dos archivos PNG aparecen en el directorio de trabajo de la aplicación: + +* `DatabarCols4.png` – un código de barras DataBar Expanded Stacked con cuatro columnas verticales. +* `DatabarRows3.png` – la misma simbología organizada en tres filas horizontales. + +Ambas imágenes pueden abrirse en cualquier visor de imágenes o incrustarse en un control de UI. + +--- + +## Preguntas frecuentes y casos límite + +| Pregunta | Respuesta | +|----------|-----------| +| *¿Puedo usar una simbología de código de barras diferente?* | Sí. Reemplaza `EncodeTypes.DatabarExpandedStacked` por otro valor de `EncodeTypes` (p. ej., `EncodeTypes.QR`), pero las propiedades `Columns` y `Rows` son específicas de las familias DataBar. | +| *¿Qué ocurre si la cadena de datos supera la longitud máxima?* | La simbología DataBar Expanded Stacked admite hasta 61 caracteres numéricos. Superar este límite lanza una `ArgumentException`. Valida la entrada antes de asignarla al generador. | +| *¿Necesito disponer de `BarcodeGenerator`?* | `BarcodeGenerator` implementa `IDisposable`. En un servicio de larga ejecución, envuélvelo en un bloque `using` o llama a `Dispose()` manualmente para liberar recursos nativos. | +| *¿Puedo generar SVG en lugar de PNG?* | Por supuesto. Usa `BarCodeImageFormat.Svg` en el método `Save`. | +| *¿La biblioteca es compatible con .NET Core?* | Aspose.BarCode para .NET soporta .NET Core 3.1, .NET 5, .NET 6 y versiones posteriores. No se requieren cambios de código. | + +--- + +## Conclusión + +Ahora sabes cómo **crear un código de barras databar de 4 columnas** en C# usando Aspose.BarCode, cómo ajustar el diseño con filas y cómo exportar el resultado en un **formato de imagen de código de barras** conveniente. El ejemplo completo muestra configuraciones basadas en columnas y en filas, dándote una base sólida para cualquier escenario de impresión de etiquetas o escaneo móvil. + +**Próximos pasos** + +* Experimenta con diferentes cargas de datos y verifica la compatibilidad del escáner. +* Explora opciones de estilo adicionales como colores de primer plano/fondo (`generator.Parameters.Barcode.Color`). +* Combina el código de barras con otros gráficos usando la API `Graphics` para diseños de etiquetas personalizados. + +Siéntete libre de adaptar el código para proyectos ASP.NET Core, Windows Forms o Xamarin—Aspose.BarCode funciona en todas las plataformas .NET. ¡Feliz codificación! + +## ¿Qué deberías aprender a continuación? + +Los siguientes tutoriales cubren temas estrechamente relacionados que amplían las técnicas demostradas en esta guía.

Verás cómo controlar los **píxeles de altura del código de barras**, guardar la imagen y producir **múltiples códigos de barras** sin duplicar código. + +El tutorial cubre todo, desde la instalación del paquete hasta la personalización de dimensiones, para que puedas copiar‑pegar un ejemplo listo para ejecutar en tu proyecto hoy mismo. + +## Requisitos previos + +Antes de comenzar, asegúrate de tener: + +* SDK .NET 6.0 o posterior instalado +* Visual Studio 2022 (o cualquier IDE de C#) +* Paquete NuGet `Aspose.BarCode` – instalar con + +```bash +dotnet add package Aspose.BarCode +``` + +No se requieren dependencias adicionales. + +## Cómo generar una imagen de código de barras con BarcodeGenerator C# + +La clase principal para crear una imagen de código de barras es `BarcodeGenerator`. Encapsula el tipo de codificación, la cadena de datos y todos los parámetros de renderizado. + +### Paso 1: Definir la carpeta de salida + +Elige una carpeta donde se almacenarán los archivos PNG generados. Usar una ruta absoluta evita sorpresas de permisos. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **¿Por qué?** Crear la carpeta programáticamente garantiza que las llamadas posteriores a `Save` tengan éxito incluso en una máquina nueva. + +### Paso 2: Instanciar el generador de códigos de barras + +Para un código de barras DataBar Omnidirectional, pasa `EncodeTypes.DatabarOmniDirectional` y la cadena de datos GS1‑128. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Nota:** El objeto `BarcodeGenerator` es reutilizable; puedes cambiar sus parámetros entre guardados para **crear múltiples códigos de barras** a partir de los mismos datos. + +### Paso 3: Establecer los parámetros comunes del código de barras + +Los ajustes visuales más comunes son la X‑dimension (ancho del módulo) y la altura de la barra. Ambos se expresan en píxeles. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **¿Por qué establecer la X‑dimension?** Una X‑dimension más pequeña produce mayor resolución, lo cual es importante cuando la imagen se imprimirá o mostrará en pantallas de alta DPI. + +### Paso 4: Guardar la primera imagen de código de barras + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +El archivo `DatabarBarHeight30Pixels.png` ahora contiene un código de barras DataBar Omnidirectional de 30 píxeles de altura. + +### Paso 5: Ajustar los píxeles de altura del código de barras + +Cambiar la altura no requiere una nueva instancia de `BarcodeGenerator`, solo modifica el parámetro. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Paso 6: Guardar la segunda imagen de código de barras + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Ahora tienes dos archivos PNG con diferentes **píxeles de altura del código de barras**, demostrando lo fácil que es crear variaciones de **imagen de código de barras**. + +## Configurar dinámicamente los píxeles de altura del código de barras + +A menudo necesitas una serie de códigos de barras con alturas que coincidan con elementos de UI o etiquetas impresas. El siguiente método auxiliar abstrae el cambio de altura: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Ahora puedes llamar a `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` para **crear una imagen de código de barras** con una altura de 45 píxeles en una sola línea. + +## Crear múltiples códigos de barras en un bucle + +Cuando tienes una colección de identificadores de producto, un bucle `foreach` elimina el código repetitivo. Este ejemplo muestra cómo **crear múltiples códigos de barras** a partir de un arreglo de GTINs. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +El bucle produce tres archivos PNG, cada uno con un valor distinto de **píxeles de altura del código de barras**. Como el método auxiliar `SaveBarcodeWithHeight` encapsula el cambio de altura, el bucle principal se mantiene limpio y centrado en los datos. + +### Resultado esperado + +Después de ejecutar el ejemplo completo, la carpeta `Barcodes` contiene: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Abrir cualquier PNG muestra un código de barras DataBar Omnidirectional nítido que puede ser escaneado por aplicaciones móviles estándar. + +## Errores comunes y consejos profesionales + +| Problema | Por qué ocurre | Cómo evitarlo | +|----------|----------------|---------------| +| **EncodeTypes incorrectos** | Usar un tipo 1D para un DataBar producirá una imagen ilegible. | Siempre elige `EncodeTypes.DatabarOmniDirectional` (u otra variante DataBar) para cargas útiles GS1‑128. | +| **X‑dimension insuficiente** | Una X‑dimension muy baja puede hacer que las barras finas desaparezcan en monitores de baja resolución. | Mantén `XDimension.Pixels` ≥ 2 para visualización en pantalla; aumenta a 3‑4 para impresión. | +| **Errores de ruta de archivo** | Las rutas relativas pueden resolverse a directorios inesperados. | Usa `Path.Combine` y `Environment.CurrentDirectory` para construir rutas absolutas. | +| **Sobrescritura de imágenes** | Reutilizar el mismo nombre de archivo en un bucle sobrescribe resultados anteriores. | Incluye identificadores únicos (p. ej., GTIN o marca de tiempo) en el nombre del archivo. | +| **Paquete NuGet faltante** | El código compila pero lanza `FileNotFoundException` en tiempo de ejecución. | Verifica que `Aspose.BarCode` esté instalado y que el proyecto lo referencie. | + +## Ejemplo completo en funcionamiento + +A continuación se muestra el programa completo que puedes copiar en una aplicación de consola.

Encontrarás dos archivos PNG: + +* **DatabarAspectRatio15.png** – un código de barras compacto adecuado para etiquetas de altura limitada. +* **DatabarAspectRatio30.png** – un código de barras más alto que muchos escáneres leen de manera más fiable a distancia. + +Ambas imágenes están listas para incrustarse en PDFs, imprimirse en recibos o enviarse a una aplicación móvil. + +## Paso 4: Extender la solución para generar cualquier número de códigos de barras + +El patrón mostrado arriba escala fácilmente: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – El bucle itera sobre una matriz de relaciones de aspecto, creando una **imagen de código de barras** distinta para cada valor. +* Ajusta `EncodeTypes` o la cadena codificada para generar códigos QR, Code 128 u otras simbologías sin cambiar la lógica circundante. + +## Consejos prácticos y errores comunes + +| Consejo | Explicación | +|-----|-------------| +| **Reutilizar el mismo generador** | Re‑inicializar `BarcodeGenerator` para cada imagen añade una sobrecarga innecesaria. Cambiar los parámetros entre llamadas a `Save` es más rápido y usa menos memoria. | +| **Validar la carpeta de salida** | Siempre llama a `Directory.CreateDirectory` antes de guardar; de lo contrario `Save` lanza una `DirectoryNotFoundException`. | +| **Elegir una X‑dimension adecuada** | Valores de píxeles muy bajos (p. ej., 1) pueden hacer que el código de barras sea ilegible en pantallas de baja resolución. Valores de 2–3 funcionan bien para la mayoría de impresoras. | +| **Cuidar la codificación** | GS1 DataBar espera un prefijo `(01)` para GTIN. Si omites los paréntesis, la biblioteca puede generar un código de barras inválido. | +| **Probar con un escáner real** | La inspección visual no es suficiente.

Vi går igenom att generera en DataBar Expanded Stacked streckkod, konfigurera fyra kolumner och spara resultatet som en PNG‑bild. + +I den här guiden kommer du att lära dig hur du: + +* Initierar `BarcodeGenerator` för en **DataBar Expanded Stacked**‑symbol. +* Ställer in kolumnantalet till 4 (huvudkravet). +* Justerar radantalet när du behöver en staplad layout med tre rader. +* Exporterar streckkoden som en PNG med det lämpliga **barcode image format**. + +Du behöver bara Aspose.BarCode for .NET‑biblioteket (version 23.10 eller senare) och en .NET 6+ utvecklingsmiljö såsom Visual Studio 2022. Inga ytterligare beroenden krävs. + +--- + +## Så skapar du 4‑kolumns databar streckkod + +Det första steget är att skapa en `BarcodeGenerator`‑instans som riktar sig mot **DataBar Expanded Stacked**‑symboliken. Denna klass kapslar in alla renderingsalternativ, vilket gör det enkelt att växla mellan kolumn‑baserade och rad‑baserade layouter. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Varför detta fungerar:** +`EncodeTypes.DatabarExpandedStacked` talar om för Aspose.BarCode att producera den staplade versionen av DataBar‑familjen. `DataBar.Columns`‑egenskapen styr hur många vertikala moduler streckkoden upptar. Att sätta den till 4 uppfyller kravet att **skapa 4‑kolumns databar streckkod**. Slutligen skriver `Save` den visuella representationen till disk med **barcode image format** `Png`. + +### Konfigurera DataBar Expanded Stacked‑kolumner + +Om du behöver ett annat kolumnantal, ändra helt enkelt heltalet som tilldelas `Columns`. Egenskapen accepterar värden från 1 till 4 för den expanderade staplade varianten. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Pro tip:* Testa alltid den genererade streckkoden med en scanner som stöder DataBar‑familjen, eftersom enbart det visuella utseendet inte garanterar läsbarhet. + +### Spara streckkodbilden + +`BarCodeImageFormat`‑enumerationen erbjuder flera alternativ (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG är förlustfri och fungerar bra för de flesta webb‑ och desktop‑scenarier. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Om du behöver ett annat format, ersätt `Png` med önskat enum‑värde. Den sparade filen kan bäddas in direkt i HTML, PDF‑filer eller skrivas ut på etiketter. + +## Skapa en streckkod med anpassade rader + +Ibland krävs en staplad layout med ett specifikt antal rader istället för kolumner. Samma `BarcodeGenerator`‑klass exponerar en `Rows`‑egenskap för detta ändamål. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Varför rader är viktiga:** +När den staplade streckkoden är högre än den är bred, bestämmer `Rows`‑egenskapen hur många horisontella segment symbolen delas in i. Att sätta `Rows = 3` skapar en staplad streckkod med tre rader, vilket är användbart för smala etikettbredder. + +### Ställ in streckkodens rader dynamiskt + +Du kan beräkna radantalet vid körning baserat på indata: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Denna flexibilitet låter dig **ställa in streckkodens rader** utan att behöva kompilera om applikationen. + +## Fullständigt end‑to‑end‑exempel + +Nedan är ett enda program som genererar både en 4‑kolumns streckkod och en 3‑radig streckkod, vilket demonstrerar hur de två konfigurationerna kan samexistera. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Förväntat resultat:** +Två PNG‑filer visas i applikationens arbetskatalog: + +* `DatabarCols4.png` – en DataBar Expanded Stacked‑streckkod med fyra vertikala kolumner. +* `DatabarRows3.png` – samma symbolik arrangerad i tre horisontella rader. + +Båda bilderna kan öppnas i vilken bildvisare som helst eller bäddas in i en UI‑kontroll. + +--- + +## Vanliga frågor och edge cases + +| Question | Answer | +|----------|--------| +| *Kan jag använda en annan streckkodssymbol?* | Ja. Ersätt `EncodeTypes.DatabarExpandedStacked` med ett annat `EncodeTypes`‑värde (t.ex. `EncodeTypes.QR`), men `Columns`‑ och `Rows`‑egenskaperna är specifika för DataBar‑familjer. | +| *Vad händer om datasträngen överskrider maximal längd?* | DataBar Expanded Stacked‑symboliken stödjer upp till 61 numeriska tecken. Att överskrida denna gräns kastar ett `ArgumentException`. Validera indata innan du tilldelar den till generatorn. | +| *Behöver jag avlasta `BarcodeGenerator`?* | `BarcodeGenerator` implementerar `IDisposable`. I en långvarig tjänst, omslut den i ett `using`‑block eller anropa `Dispose()` manuellt för att frigöra inhemska resurser. | +| *Kan jag generera SVG istället för PNG?* | Absolut. Använd `BarCodeImageFormat.Svg` i `Save`‑metoden. | +| *Är biblioteket kompatibelt med .NET Core?* | Aspose.BarCode for .NET stödjer .NET Core 3.1, .NET 5, .NET 6 och senare. Inga kodändringar krävs. | + +--- + +## Slutsats + +Du vet nu hur du **skapar 4‑kolumns databar streckkod** i C# med Aspose.BarCode, hur du justerar layouten med rader, och hur du exporterar resultatet i ett bekvämt **barcode image format**. Det kompletta exemplet visar både kolumn‑baserade och rad‑baserade konfigurationer, vilket ger dig en solid grund för alla etikett‑utskrift‑ eller mobil‑scanningsscenarier. + +**Nästa steg** + +* Experimentera med olika datapayloads och verifiera scanner‑kompatibilitet. +* Utforska ytterligare stilalternativ såsom förgrunds‑/bakgrundsfärger (`generator.Parameters.Barcode.Color`). +* Kombinera streckkoden med annan grafik via `Graphics`‑API:t för anpassade etikettdesigner. + +Känn dig fri att anpassa koden för ASP.NET Core, Windows Forms eller Xamarin‑projekt—Aspose.BarCode fungerar på alla .NET‑plattformar.

Den kapslar in kodningstypen, datasträngen och alla renderingsparametrar. + +### Steg 1: Definiera utdatamappen + +Välj en mapp där de genererade PNG‑filerna ska lagras. Att använda en absolut sökväg undviker behörighetsöverraskningar. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Varför?** Att skapa mappen programatiskt garanterar att de efterföljande `Save`‑anropen lyckas även på en ny maskin. + +### Steg 2: Instansiera streckkodsgeneratorn + +För en DataBar Omnidirectional‑streckkod, skicka `EncodeTypes.DatabarOmniDirectional` och GS1‑128‑datasträngen. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Obs:** `BarcodeGenerator`‑objektet är återanvändbart; du kan ändra dess parametrar mellan sparningar för att **create multiple barcodes** från samma data. + +### Steg 3: Ställ in vanliga streckkodparametrar + +De vanligaste visuella justeringarna är X‑dimensionen (modulbredd) och stapelhöjden. Båda uttrycks i pixlar. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Varför sätta X‑dimension?** En mindre X‑dimension ger högre upplösning, vilket är viktigt när bilden ska skrivas ut eller visas på hög‑DPI‑skärmar. + +### Steg 4: Spara den första streckkodbilden + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Filen `DatabarBarHeight30Pixels.png` innehåller nu en 30‑pixel‑hög DataBar Omnidirectional‑streckkod. + +### Steg 5: Justera streckkodens höjd i pixlar + +Att ändra höjden kräver ingen ny `BarcodeGenerator`‑instans – ändra bara parametern. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Steg 6: Spara den andra streckkodbilden + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Nu har du två PNG‑filer med olika **barcode height pixels**, vilket visar hur enkelt det är att **create barcode image**‑varianter. + +## Ställa in streckkodens höjd i pixlar dynamiskt + +Ofta behöver du en serie streckkoder med höjder som matchar UI‑element eller utskrivna etiketter. Följande hjälpfunktion abstraherar höjdändringen: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Du kan nu anropa `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` för att **create barcode image** med en 45‑pixel hög höjd i ett enda anrop. + +## Skapa flera streckkoder i en loop + +När du har en samling produktidentifierare eliminerar en `foreach`‑loop repetitiv kod. Detta exempel visar hur du **create multiple barcodes** från en array av GTIN‑värden. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +Loopen producerar tre PNG‑filer, var och en med ett distinkt **barcode height pixels**‑värde. Eftersom `SaveBarcodeWithHeight`‑hjälpen kapslar in höjdändringen, förblir huvudloopen ren och fokuserad på data. + +### Förväntad output + +Efter att ha kört hela exemplet innehåller `Barcodes`‑mappen: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Att öppna någon PNG visar en skarp DataBar Omnidirectional‑streckkod som kan skannas av vanliga mobilappar. + +## Vanliga fallgropar och proffstips + +| Problem | Varför det händer | Hur du undviker det | +|---------|-------------------|----------------------| +| **Fel EncodeTypes** | Att använda en 1D‑typ för en DataBar ger en oläslig bild. | Välj alltid `EncodeTypes.DatabarOmniDirectional` (eller en annan DataBar‑variant) för GS1‑128‑payloads. | +| **Otillräcklig X‑dimension** | Mycket låg X‑dimension kan göra tunna staplar osynliga på lågupplösta bildskärmar. | Behåll `XDimension.Pixels` ≥ 2 för skärmvisning; öka till 3‑4 för utskrift. | +| **Fel i filsökväg** | Relativa sökvägar kan lösas till oväntade kataloger. | Använd `Path.Combine` och `Environment.CurrentDirectory` för att bygga absoluta sökvägar. | +| **Överskriva bilder** | Att återanvända samma filnamn i en loop skriver över tidigare resultat. | Inkludera unika identifierare (t.ex.

Programmet skapar en **streckkodbild**, ändrar bildförhållandet och sparar två PNG‑filer. + +```csharp +using System; +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +namespace BarcodeDemo +{ + class Program + { + static void Main() + { + // ----------------------------------------------------------------- + // 1️⃣ Create a DataBar Stacked Omnidirectional generator with sample data + // ----------------------------------------------------------------- + // The EncodeTypes enum tells the generator which barcode symbology to use. + // Here we use DataBar Stacked Omnidirectional (GS1 DataBar) and encode + // a sample GTIN (01) followed by a 14‑digit numeric string. + var generator = new BarcodeGenerator( + EncodeTypes.DatabarStackedOmniDirectional, + "(01)12345678901231"); + + // ----------------------------------------------------------------- + // 2️⃣ Configure common parameters (pixel size and X‑dimension) + // ----------------------------------------------------------------- + // XDimension.Pixels controls the width of the smallest bar in the image. + // A value of 2 gives a clear, high‑resolution output without increasing file size. + generator.Parameters.Barcode.XDimension.Pixels = 2; + + // ----------------------------------------------------------------- + // 3️⃣ Set the first aspect ratio (15) and save the image + // ----------------------------------------------------------------- + // AspectRatio influences the height of the barcode relative to its width. + // An aspect ratio of 15 is typical for compact labels. + generator.Parameters.Barcode.DataBar.AspectRatio = 15; + + string outputFolder = "BarcodeOutputs/"; + System.IO.Directory.CreateDirectory(outputFolder); // Ensure folder exists + + string file15 = $"{outputFolder}DatabarAspectRatio15.png"; + generator.Save(file15, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 15 → {file15}"); + + // ----------------------------------------------------------------- + // 4️⃣ Change the aspect ratio to 30 and save a second image + // ----------------------------------------------------------------- + // A larger aspect ratio (e.g., 30) produces a taller barcode, useful for + // scanning devices that expect more vertical space. + generator.Parameters.Barcode.DataBar.AspectRatio = 30; + + string file30 = $"{outputFolder}DatabarAspectRatio30.png"; + generator.Save(file30, BarCodeImageFormat.Png); + Console.WriteLine($"Saved barcode with aspect ratio 30 → {file30}"); + + // ----------------------------------------------------------------- + // 5️⃣ Verify that both files exist + // ----------------------------------------------------------------- + Console.WriteLine("\nVerification:"); + Console.WriteLine($"File 15 exists: {System.IO.File.Exists(file15)}"); + Console.WriteLine($"File 30 exists: {System.IO.File.Exists(file30)}"); + } + } +} +``` + +### Varför varje del är viktig + +* **Create barcode image** – `BarcodeGenerator`‑konstruktorn initierar objektet med den önskade symbologin och datan. +* **c# barcode generator** – `Parameters`‑egenskapen ger dig full kontroll över renderingsalternativ; att sätta `XDimension.Pixels` säkerställer att varje stapel är skarp på skärmen. +* **generate multiple barcodes** – Genom att ändra `DataBar.AspectRatio` mellan sparningar producerar samma generatorinstans två olika bilder utan att återskapa objektet, vilket är mer effektivt. + +## Steg 3: Kör programmet och visa resultaten + +Kör applikationen: + +```bash +dotnet run +``` + +Du bör se konsolutdata liknande: + +``` +Saved barcode with aspect ratio 15 → BarcodeOutputs/DatabarAspectRatio15.png +Saved barcode with aspect ratio 30 → BarcodeOutputs/DatabarAspectRatio30.png + +Verification: +File 15 exists: True +File 30 exists: True +``` + +Öppna mappen `BarcodeOutputs`. Du kommer att hitta två PNG‑filer: + +* **DatabarAspectRatio15.png** – en kompakt streckkod lämplig för etiketter med begränsad höjd. +* **DatabarAspectRatio30.png** – en högre streckkod som många skannrar läser mer pålitligt på avstånd. + +Båda bilderna är klara att bäddas in i PDF‑filer, skrivas ut på kvitton eller skickas till en mobilapp. + +## Steg 4: Utöka lösningen för att generera valfritt antal streckkoder + +Mönstret som visas ovan skalar enkelt: + +```csharp +int[] ratios = { 10, 15, 20, 30, 40 }; +foreach (int ratio in ratios) +{ + generator.Parameters.Barcode.DataBar.AspectRatio = ratio; + string path = $"{outputFolder}DatabarAspectRatio{ratio}.png"; + generator.Save(path, BarCodeImageFormat.Png); + Console.WriteLine($"Saved aspect ratio {ratio} → {path}"); +} +``` + +* **generate multiple barcodes** – Loopen itererar över en array av bildförhållanden och skapar en distinkt **barcode image** för varje värde. +* Justera `EncodeTypes` eller den kodade strängen för att producera QR‑koder, Code 128 eller andra symbologier utan att ändra den omgivande logiken. + +## Praktiska tips och vanliga fallgropar + +| Tip | Explanation | +|-----|-------------| +| **Reuse the same generator** | Att återinitiera `BarcodeGenerator` för varje bild lägger till onödig overhead. Att ändra parametrar mellan `Save`‑anrop är snabbare och använder mindre minne. | +| **Validate the output folder** | Anropa alltid `Directory.CreateDirectory` innan du sparar; annars kastar `Save` ett `DirectoryNotFoundException`. | +| **Choose an appropriate X‑dimension** | Mycket låga pixelvärden (t.ex. 1) kan göra streckkoden oläslig på lågupplösta skärmar. Värden på 2–3 fungerar bra för de flesta skrivare. | +| **Mind the encoding** | GS1 DataBar förväntar sig en inledande `(01)` för GTIN. Om du utelämnar parenteserna kan biblioteket generera en ogiltig streckkod. | +| **Test with a real scanner** | Visuell inspektion räcker inte. Testa PNG‑filerna med den faktiska skannerutrustning du planerar att använda. | + +## Förväntat resultat (visuell beskrivning) + +*Båda PNG‑filerna visar en mörk‑på‑ljus DataBar Stacked Omnidirectional‑streckkod. Versionen med bildförhållande 15 är kortare, medan versionen med bildförhållande 30 är ungefär dubbelt så hög.* + +Om du bäddar in bilderna i ett dokument kommer de att renderas skarpt eftersom vi satte `XDimension.Pixels = 2`. + +## Slutsats + +Du vet nu hur du **skapar streckkodbild**‑filer med en **C# streckkodsgenerator**, och du kan **generera flera streckkoder** genom att justera bildförhållandet eller någon annan parameter. Det kompletta, körbara exemplet visar bästa praxis såsom att återanvända generatorinstansen, hantera utdatamappar och verifiera filskapande. + +Nästa steg kan vara att utforska: + +* Lägga till anpassade färger med `generator.Parameters.Barcode.Color` (sekundärt nyckelord: **c# barcode generator**) +* Exportera till andra format som JPEG eller SVG (`BarCodeImageFormat.Jpeg`, `BarCodeImageFormat.Svg`) +* Integrera streckkodsskapande logik i ett Web API för att leverera bilder på begäran (sekundärt nyckelord + +## Vad bör du lära dig härnäst? + +Följande handledningar täcker närbesläktade ämnen som bygger på teknikerna som demonstrerats i den här guiden.

Exceeding this limit throws an `ArgumentException`. Validate the input before assigning it to the generator. | +| *Do I need to dispose the `BarcodeGenerator`?* | `BarcodeGenerator` implements `IDisposable`. In a long‑running service, wrap it in a `using` block or call `Dispose()` manually to free native resources. | +| *Can I generate SVG instead of PNG?* | Absolutely. Use `BarCodeImageFormat.Svg` in the `Save` method. | +| *Is the library compatible with .NET Core?* | Aspose.BarCode for .NET supports .NET Core 3.1, .NET 5, .NET 6, and later.

DataBar Expanded Stacked barkodu oluşturmayı, dört sütunu yapılandırmayı ve sonucu PNG görüntüsü olarak kaydetmeyi adım adım anlatacağız. + +Bu rehberde şunları öğreneceksiniz: + +* **DataBar Expanded Stacked** sembolü için `BarcodeGenerator` nesnesini başlatmak. +* Sütun sayısını 4 olarak ayarlamak (ana gereksinim). +* Üç satır içeren bir yığılmış düzen gerektiğinde satır sayısını ayarlamak. +* Uygun **barkod görüntü formatı** kullanarak barkodu PNG olarak dışa aktarmak. + +Sadece Aspose.BarCode for .NET kütüphanesine (sürüm 23.10 veya daha yenisi) ve Visual Studio 2022 gibi bir .NET 6+ geliştirme ortamına ihtiyacınız var. Başka bir bağımlılık gerekmez. + +--- + +## 4‑sütunlu databar barkod nasıl oluşturulur + +İlk adım, **DataBar Expanded Stacked** sembolünü hedefleyen bir `BarcodeGenerator` örneği oluşturmaktır. Bu sınıf, tüm render seçeneklerini kapsar ve sütun‑tabanlı ile satır‑tabanlı düzenler arasında geçişi kolaylaştırır. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Neden bu şekilde çalışır:** +`EncodeTypes.DatabarExpandedStacked` Aspose.BarCode’e DataBar ailesinin yığılmış versiyonunu üretmesini söyler. `DataBar.Columns` özelliği, barkodun kaç dikey modül kaplayacağını kontrol eder. Bunu 4 olarak ayarlamak, **4‑sütunlu databar barkod oluşturma** gereksinimini karşılar. Son olarak `Save`, görsel temsili **barkod görüntü formatı** `Png` kullanarak diske yazar. + +### DataBar Expanded Stacked sütunlarını yapılandırma + +Farklı bir sütun sayısına ihtiyacınız varsa, sadece `Columns` değişkenine atanan tam sayıyı değiştirin. Bu özellik, yığılmış genişletilmiş varyant için 1‑den 4‑e kadar değerleri kabul eder. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*İpucu:* Oluşturulan barkodu, DataBar ailesini destekleyen bir tarayıcıyla her zaman test edin; çünkü yalnızca görsel görünüm okunabilirliği garanti etmez. + +### Barkod görüntüsünü kaydetme + +`BarCodeImageFormat` enum’u birkaç seçenek sunar (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG kayıpsızdır ve çoğu web ve masaüstü senaryosu için iyidir. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Farklı bir format istiyorsanız, `Png` yerine istediğiniz enum değerini kullanın. Kaydedilen dosya doğrudan HTML, PDF’lere gömülebilir veya etiketlere basılabilir. + +## Özel satırlarla barkod oluşturma + +Bazen sütunlar yerine belirli bir satır sayısı gerektiren bir yığılmış düzen istenir. Aynı `BarcodeGenerator` sınıfı bu amaçla bir `Rows` özelliği sunar. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Satırların önemi:** +Yığılmış barkod genişliğinden daha yüksek olduğunda, `Rows` özelliği sembolün kaç yatay dilime bölüneceğini belirler. `Rows = 3` ayarı, dar etiket genişlikleri için faydalı olan üç satırlı bir yığılmış barkod oluşturur. + +### Barkod satırlarını dinamik olarak ayarlama + +Satır sayısını, giriş verisine göre çalışma zamanında hesaplayabilirsiniz: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Bu esneklik, uygulamayı yeniden derlemeden **barkod satırlarını ayarlamanıza** olanak tanır. + +## Tam uçtan uca örnek + +Aşağıda, hem 4‑sütunlu hem de 3‑satırlı barkod üreten tek bir program yer alıyor; iki konfigürasyonun nasıl birlikte kullanılabileceğini gösteriyor. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Beklenen çıktı:** +Uygulamanın çalışma dizininde iki PNG dosyası oluşur: + +* `DatabarCols4.png` – dört dikey sütunlu bir DataBar Expanded Stacked barkod. +* `DatabarRows3.png` – aynı sembolün üç yatay satır halinde düzenlenmiş hali. + +Her iki görüntü de herhangi bir görüntü görüntüleyicide açılabilir veya bir UI kontrolüne gömülebilir. + +--- + +## Yaygın sorular ve kenar durumları + +| Soru | Cevap | +|------|-------| +| *Farklı bir barkod sembolü kullanabilir miyim?* | Evet. `EncodeTypes.DatabarExpandedStacked` yerine başka bir `EncodeTypes` değeri (ör. `EncodeTypes.QR`) kullanın, ancak `Columns` ve `Rows` özellikleri yalnızca DataBar ailelerine özeldir. | +| *Veri dizesi maksimum uzunluğu aşıyorsa ne olur?* | DataBar Expanded Stacked sembolü en fazla 61 sayısal karakteri destekler. Bu sınır aşılırsa `ArgumentException` fırlatılır. Girişi jeneratöre atamadan önce doğrulayın. | +| *`BarcodeGenerator` nesnesini dispose etmem gerekiyor mu?* | `BarcodeGenerator` `IDisposable` uygular. Uzun‑çalışan bir serviste, `using` bloğu içinde kullanın veya native kaynakları serbest bırakmak için `Dispose()` metodunu manuel olarak çağırın. | +| *PNG yerine SVG üretebilir miyim?* | Kesinlikle. `Save` metodunda `BarCodeImageFormat.Svg` kullanın. | +| *Kütüphane .NET Core ile uyumlu mu?* | Aspose.BarCode for .NET, .NET Core 3.1, .NET 5, .NET 6 ve sonrası sürümleri destekler. Kodda değişiklik yapmanız gerekmez. | + +--- + +## Sonuç + +Artık Aspose.BarCode kullanarak C#’ta **4‑sütunlu databar barkod oluşturmayı**, satırlarla düzeni ayarlamayı ve sonucu kullanışlı bir **barkod görüntü formatı** ile dışa aktarmayı biliyorsunuz.

Chúng tôi sẽ hướng dẫn cách tạo mã vạch DataBar Expanded Stacked, cấu hình bốn cột và lưu kết quả dưới dạng ảnh PNG. + +Trong hướng dẫn này bạn sẽ học cách: + +* Khởi tạo `BarcodeGenerator` cho ký hiệu **DataBar Expanded Stacked**. +* Đặt số cột thành 4 (yêu cầu chính). +* Điều chỉnh số hàng khi bạn cần bố cục stacked với ba hàng. +* Xuất mã vạch dưới dạng PNG bằng **định dạng ảnh mã vạch** phù hợp. + +Bạn chỉ cần thư viện Aspose.BarCode cho .NET (phiên bản 23.10 trở lên) và môi trường phát triển .NET 6+ như Visual Studio 2022. Không cần phụ thuộc nào khác. + +--- + +## Cách tạo mã vạch databar 4‑cột + +Bước đầu tiên là tạo một thể hiện `BarcodeGenerator` nhắm tới ký hiệu **DataBar Expanded Stacked**. Lớp này bao gồm tất cả các tùy chọn render, giúp việc chuyển đổi giữa bố cục dựa trên cột và dựa trên hàng trở nên đơn giản. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class Program +{ + static void Main() + { + // 1️⃣ Initialise a generator for DataBar Expanded Stacked + BarcodeGenerator generator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Set the barcode to use a 4‑column layout + generator.Parameters.Barcode.DataBar.Columns = 4; + + // 3️⃣ Save the image as PNG + generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); + } +} +``` + +**Tại sao cách này hoạt động:** +`EncodeTypes.DatabarExpandedStacked` báo cho Aspose.BarCode tạo ra phiên bản stacked của họ DataBar. Thuộc tính `DataBar.Columns` kiểm soát số mô-đun dọc mà mã vạch chiếm. Đặt nó thành 4 đáp ứng yêu cầu **tạo mã vạch databar 4‑cột**. Cuối cùng, `Save` ghi hình ảnh biểu diễn ra đĩa bằng **định dạng ảnh mã vạch** `Png`. + +### Cấu hình các cột cho DataBar Expanded Stacked + +Nếu bạn cần số cột khác, chỉ cần thay đổi số nguyên gán cho `Columns`. Thuộc tính này chấp nhận giá trị từ 1 đến 4 cho biến thể stacked mở rộng. + +```csharp +// Example: switch to a 2‑column layout +generator.Parameters.Barcode.DataBar.Columns = 2; +``` + +*Mẹo:* Luôn kiểm tra mã vạch đã tạo bằng máy quét hỗ trợ họ DataBar, vì chỉ nhìn thấy hình ảnh không đảm bảo khả năng đọc. + +### Lưu ảnh mã vạch + +Kiểu liệt kê `BarCodeImageFormat` cung cấp một số tùy chọn (`Png`, `Jpeg`, `Bmp`, `Gif`, `Tiff`). PNG không mất dữ liệu và hoạt động tốt cho hầu hết các kịch bản web và desktop. + +```csharp +generator.Save("DatabarCols4.png", BarCodeImageFormat.Png); +``` + +Nếu bạn cần định dạng khác, thay `Png` bằng giá trị enum mong muốn. Tệp đã lưu có thể nhúng trực tiếp vào HTML, PDF, hoặc in trên nhãn. + +## Tạo mã vạch với các hàng tùy chỉnh + +Đôi khi cần bố cục stacked với số hàng cụ thể thay vì số cột. Lớp `BarcodeGenerator` cũng cung cấp thuộc tính `Rows` cho mục đích này. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class RowExample +{ + static void Main() + { + // 1️⃣ Initialise a generator for the same symbology + BarcodeGenerator rowGenerator = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + + // 2️⃣ Configure the barcode to use a 3‑row layout + rowGenerator.Parameters.Barcode.DataBar.Rows = 3; + + // 3️⃣ Save the image as PNG + rowGenerator.Save("DatabarRows3.png", BarCodeImageFormat.Png); + } +} +``` + +**Tại sao hàng quan trọng:** +Khi mã vạch stacked cao hơn chiều rộng, thuộc tính `Rows` xác định số lát ngang mà ký hiệu được chia. Đặt `Rows = 3` tạo ra một mã vạch stacked ba hàng, hữu ích cho nhãn có chiều rộng hẹp. + +### Đặt số hàng của mã vạch một cách động + +Bạn có thể tính số hàng tại thời gian chạy dựa trên dữ liệu đầu vào: + +```csharp +int desiredRows = GetRowsFromUser(); // your custom logic +rowGenerator.Parameters.Barcode.DataBar.Rows = desiredRows; +``` + +Tính linh hoạt này cho phép bạn **đặt số hàng của mã vạch** mà không cần biên dịch lại ứng dụng. + +## Ví dụ đầy đủ từ đầu đến cuối + +Dưới đây là một chương trình duy nhất tạo cả mã vạch 4‑cột và mã vạch 3‑hàng, minh họa cách hai cấu hình này cùng tồn tại. + +```csharp +using Aspose.BarCode.Generation; +using Aspose.BarCode; + +class FullExample +{ + static void Main() + { + // ---------- 4‑column barcode ---------- + BarcodeGenerator colGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + colGen.Parameters.Barcode.DataBar.Columns = 4; // create 4‑column databar barcode + colGen.Save("DatabarCols4.png", BarCodeImageFormat.Png); + + // ---------- 3‑row barcode ---------- + BarcodeGenerator rowGen = new BarcodeGenerator( + EncodeTypes.DatabarExpandedStacked, + "Databar Expanded Stacked long"); + rowGen.Parameters.Barcode.DataBar.Rows = 3; // set barcode rows to 3 + rowGen.Save("DatabarRows3.png", BarCodeImageFormat.Png); + + // Output confirmation + System.Console.WriteLine("Barcodes generated:"); + System.Console.WriteLine(" - DatabarCols4.png (4 columns)"); + System.Console.WriteLine(" - DatabarRows3.png (3 rows)"); + } +} +``` + +**Kết quả mong đợi:** +Hai tệp PNG xuất hiện trong thư mục làm việc của ứng dụng: + +* `DatabarCols4.png` – một mã vạch DataBar Expanded Stacked với bốn cột dọc. +* `DatabarRows3.png` – cùng ký hiệu được sắp xếp thành ba hàng ngang. + +Cả hai ảnh đều có thể mở bằng bất kỳ trình xem ảnh nào hoặc nhúng vào điều khiển UI. + +--- + +## Các câu hỏi thường gặp và các trường hợp đặc biệt + +| Câu hỏi | Trả lời | +|----------|--------| +| *Bạn có thể sử dụng ký hiệu mã vạch khác không?* | Có. Thay `EncodeTypes.DatabarExpandedStacked` bằng một giá trị `EncodeTypes` khác (ví dụ, `EncodeTypes.QR`), nhưng các thuộc tính `Columns` và `Rows` chỉ áp dụng cho họ DataBar. | +| *Nếu chuỗi dữ liệu vượt quá độ dài tối đa thì sao?* | Ký hiệu DataBar Expanded Stacked hỗ trợ tối đa 61 ký tự số. Vượt quá giới hạn này sẽ gây ra `ArgumentException`. Hãy kiểm tra đầu vào trước khi gán cho generator. | +| *Có cần giải phóng `BarcodeGenerator` không?* | `BarcodeGenerator` triển khai `IDisposable`. Trong dịch vụ chạy lâu, hãy bọc nó trong khối `using` hoặc gọi `Dispose()` thủ công để giải phóng tài nguyên gốc. | +| *Có thể tạo SVG thay vì PNG không?* | Chắc chắn. Sử dụng `BarCodeImageFormat.Svg` trong phương thức `Save`. | +| *Thư viện có tương thích với .NET Core không?* | Aspose.BarCode cho .NET hỗ trợ .NET Core 3.1, .NET 5, .NET 6 và các phiên bản sau. Không cần thay đổi mã. | + +--- + +## Kết luận + +Bạn đã biết cách **tạo mã vạch databar 4‑cột** trong C# bằng Aspose.BarCode, cách điều chỉnh bố cục bằng hàng, và cách xuất kết quả dưới dạng **định dạng ảnh mã vạch** tiện lợi.

Bạn sẽ thấy cách điều chỉnh **độ cao mã vạch tính bằng pixel**, lưu ảnh, và tạo **nhiều mã vạch** mà không cần sao chép lại mã. + +Bài tutorial bao gồm mọi thứ từ cài đặt gói đến tùy chỉnh kích thước, vì vậy bạn có thể sao chép‑dán một ví dụ đã sẵn sàng chạy vào dự án của mình ngay hôm nay. + +## Điều kiện tiên quyết + +Trước khi bắt đầu, hãy chắc chắn rằng bạn có: + +* .NET 6.0 SDK hoặc phiên bản mới hơn đã được cài đặt +* Visual Studio 2022 (hoặc bất kỳ IDE C# nào) +* Gói NuGet `Aspose.BarCode` – cài đặt bằng + +```bash +dotnet add package Aspose.BarCode +``` + +Không cần bất kỳ phụ thuộc bổ sung nào. + +## Cách tạo hình ảnh mã vạch với BarcodeGenerator C# + +Lớp cốt lõi để tạo hình ảnh mã vạch là `BarcodeGenerator`. Nó bao gồm loại mã hoá, chuỗi dữ liệu, và tất cả các tham số render. + +### Bước 1: Xác định thư mục đầu ra + +Chọn một thư mục nơi các tệp PNG được tạo sẽ được lưu. Sử dụng đường dẫn tuyệt đối giúp tránh các vấn đề về quyền truy cập. + +```csharp +// Step 1: Define the output folder +string outputFolder = Path.Combine(Environment.CurrentDirectory, "Barcodes"); +Directory.CreateDirectory(outputFolder); +``` + +> **Tại sao?** Tạo thư mục bằng chương trình đảm bảo các lệnh `Save` tiếp theo sẽ thành công ngay cả trên máy mới. + +### Bước 2: Khởi tạo barcode generator + +Đối với mã DataBar Omnidirectional, truyền `EncodeTypes.DatabarOmniDirectional` và chuỗi dữ liệu GS1‑128. + +```csharp +// Step 2: Create a DataBar Omnidirectional barcode generator with the data to encode +var barcode = new BarcodeGenerator( + EncodeTypes.DatabarOmniDirectional, "(01)12345678901231"); +``` + +> **Lưu ý:** Đối tượng `BarcodeGenerator` có thể tái sử dụng; bạn có thể thay đổi các tham số giữa các lần lưu để **tạo nhiều mã vạch** từ cùng một dữ liệu. + +### Bước 3: Đặt các tham số chung cho mã vạch + +Các điều chỉnh hình ảnh phổ biến nhất là X‑dimension (độ rộng mô-đun) và chiều cao thanh. Cả hai đều được biểu thị bằng pixel. + +```csharp +// Step 3: Set common barcode parameters (X‑dimension and initial height) +barcode.Parameters.Barcode.XDimension.Pixels = 2; // thin modules for sharper output +barcode.Parameters.Barcode.BarHeight.Pixels = 30; // initial height – 30 px +``` + +> **Tại sao phải đặt X‑dimension?** X‑dimension nhỏ hơn tạo độ phân giải cao hơn, điều này quan trọng khi hình ảnh sẽ được in hoặc hiển thị trên màn hình DPI cao. + +### Bước 4: Lưu hình ảnh mã vạch đầu tiên + +```csharp +// Step 4: Save the barcode image with a 30 px height +string file30 = Path.Combine(outputFolder, "DatabarBarHeight30Pixels.png"); +barcode.Save(file30, BarCodeImageFormat.Png); +``` + +Tệp `DatabarBarHeight30Pixels.png` bây giờ chứa một mã DataBar Omnidirectional có chiều cao 30 pixel. + +### Bước 5: Điều chỉnh chiều cao mã vạch tính bằng pixel + +Thay đổi chiều cao không cần tạo một thể hiện `BarcodeGenerator` mới—chỉ cần sửa tham số. + +```csharp +// Step 5: Change the bar height to 60 px for the same barcode +barcode.Parameters.Barcode.BarHeight.Pixels = 60; +``` + +### Bước 6: Lưu hình ảnh mã vạch thứ hai + +```csharp +// Step 6: Save the barcode image with the new 60 px height +string file60 = Path.Combine(outputFolder, "DatabarBarHeight60Pixels.png"); +barcode.Save(file60, BarCodeImageFormat.Png); +``` + +Bây giờ bạn có hai tệp PNG với **chiều cao mã vạch tính bằng pixel** khác nhau, minh họa cách dễ dàng **tạo hình ảnh mã vạch** đa dạng. + +## Đặt chiều cao mã vạch tính bằng pixel một cách động + +Thường bạn cần một loạt mã vạch với chiều cao phù hợp với các thành phần UI hoặc nhãn in. Phương thức trợ giúp dưới đây trừu tượng hoá việc thay đổi chiều cao: + +```csharp +/// +/// Saves a barcode image with a custom height. +/// +/// Configured BarcodeGenerator instance. +/// Desired bar height in pixels. +/// Target file name (including path). +void SaveBarcodeWithHeight(BarcodeGenerator generator, int heightPx, string fileName) +{ + generator.Parameters.Barcode.BarHeight.Pixels = heightPx; + generator.Save(fileName, BarCodeImageFormat.Png); +} +``` + +Bạn có thể gọi `SaveBarcodeWithHeight(barcode, 45, "BarHeight45.png");` để **tạo hình ảnh mã vạch** với chiều cao 45 pixel trong một dòng lệnh. + +## Tạo nhiều mã vạch trong vòng lặp + +Khi bạn có một tập hợp các định danh sản phẩm, vòng lặp `foreach` loại bỏ việc lặp lại mã. Ví dụ này cho thấy cách **tạo nhiều mã vạch** từ một mảng GTIN. + +```csharp +string[] gtins = { "01234567890123", "09876543210987", "12345098765432" }; +int[] heights = { 30, 45, 60 }; // different heights for visual variety + +for (int i = 0; i < gtins.Length; i++) +{ + // Encode each GTIN as a DataBar Omnidirectional barcode + var gen = new BarcodeGenerator(EncodeTypes.DatabarOmniDirectional, + $"(01){gtins[i]}"); + + // Reuse the X‑dimension setting for consistency + gen.Parameters.Barcode.XDimension.Pixels = 2; + + // Choose a height from the heights array (or calculate dynamically) + int height = heights[i % heights.Length]; + string filePath = Path.Combine(outputFolder, + $"Databar_{gtins[i]}_Height{height}px.png"); + + SaveBarcodeWithHeight(gen, height, filePath); +} +``` + +Vòng lặp tạo ra ba tệp PNG, mỗi tệp có một **giá trị chiều cao mã vạch tính bằng pixel** riêng. Vì phương thức trợ giúp `SaveBarcodeWithHeight` đã bao gói việc thay đổi chiều cao, vòng lặp chính vẫn gọn gàng và tập trung vào dữ liệu. + +### Kết quả mong đợi + +Sau khi chạy toàn bộ mẫu, thư mục `Barcodes` sẽ chứa: + +``` +DatabarBarHeight30Pixels.png +DatabarBarHeight60Pixels.png +Databar_01234567890123_Height30px.png +Databar_09876543210987_Height45px.png +Databar_12345098765432_Height60px.png +``` + +Mở bất kỳ tệp PNG nào sẽ hiển thị một mã DataBar Omnidirectional sắc nét, có thể quét bằng các ứng dụng di động tiêu chuẩn. + +## Những lỗi thường gặp và mẹo chuyên nghiệp + +| Vấn đề | Tại sao xảy ra | Cách tránh | +|-------|----------------|------------| +| **EncodeTypes sai** | Sử dụng loại 1D cho DataBar sẽ tạo ra hình ảnh không đọc được. | Luôn chọn `EncodeTypes.DatabarOmniDirectional` (hoặc biến thể DataBar khác) cho payload GS1‑128. | +| **X‑dimension không đủ** | X‑dimension quá thấp có thể làm cho các thanh mỏng biến mất trên màn hình độ phân giải thấp. | Giữ `XDimension.Pixels` ≥ 2 cho hiển thị trên màn hình; tăng lên 3‑4 cho in ấn. | +| **Lỗi đường dẫn tệp** | Đường dẫn tương đối có thể trỏ tới thư mục không mong muốn. | Sử dụng `Path.Combine` và `Environment.CurrentDirectory` để xây dựng đường dẫn tuyệt đối. | +| **Ghi đè ảnh** | Sử dụng cùng một tên tệp trong vòng lặp sẽ ghi đè kết quả trước đó. | Bao gồm các định danh duy nhất (ví dụ: GTIN hoặc timestamp) trong tên tệp. | +| **Thiếu gói NuGet** | Mã biên dịch nhưng ném `FileNotFoundException` lúc chạy. | Kiểm tra `Aspose.BarCode` đã được cài đặt và dự án đã tham chiếu tới nó. | + +## Ví dụ hoàn chỉnh hoạt động + +Dưới đây là chương trình đầy đủ mà bạn có thể sao chép vào một ứng dụng console.
