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

灰太狼 2022-06-05 09:19 289阅读 0赞

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);
