【教程】条形码组件Spire.Barcode 教程：如何在C＃中创建DataMatrix条码

摘要: Spire.Barcode是一款专业的条码组件，专为开发人员在Java应用程序（J2SE和J2EE）上生成、读取和扫描1D、2D条形码而设计，本文介绍了如何通过Spire.Barcode在Java中扫描条形码。

DataMatrix 条码是由黑色和白色“单元”组成的二维条形码，或以正方形或矩形模式排列的模块。要编码的信息可以是文本或数字数据。

代码：

Step 1:创建一个BarcodeSettings实例

BarcodeSettings settings = new BarcodeSettings();

Step 2:设置条码模块的宽度

settings.X = 2;

Step 3:将条码类型设置为DataMatrix

settings.Type = BarCodeType.DataMatrix;

Step 4:设置数据并显示文字

settings.Data = "ABC 123456789ABC 123456789ABC 123456789";
settings.Data2D = "ABC 123456789ABC 123456789ABC 123456789";

Step 5:将DataMatrix符号形状设置为正方形

settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Square;

Step 6:根据设置生成条形码图像并以.png格式保存

BarCodeGenerator generator = new BarCodeGenerator(settings);
Image image = generator.GenerateImage();
image.Save("DataMatrix.png", System.Drawing.Imaging.ImageFormat.Png);

要创建矩形的DataMatrix条形码，请将DataMatrixSymbolShape属性设置为Rectangle。

settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Rectangle;

完整代码：

BarcodeSettings settings = new BarcodeSettings();
settings.Type = BarCodeType.DataMatrix;
settings.X = 1.5f;
settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Square;
//rectangular DataMatrix barcode
//settings.DataMatrixSymbolShape = DataMatrixSymbolShape.Rectangle;
settings.Data = "ABC 123456789ABC 123456789ABC 123456789";
settings.Data2D = "ABC 123456789ABC 123456789ABC 123456789";
BarCodeGenerator generator = new BarCodeGenerator(settings);
Image image = generator.GenerateImage();
image.Save("DataMatrix.png", System.Drawing.Imaging.ImageFormat.Png);
