วิธีการ generate Micro, Compact และ Macro PDF417 Barcodes .NET

PM> Install-Package Aspose.BarCode

using Aspose.BarCode.Generation;

BarcodeGenerator microGen = new BarcodeGenerator(EncodeTypes.MicroPdf417, "Micro data");
microGen.Parameters.Barcode.XDimension.Pixels = 4; 

BarcodeGenerator compactGen = new BarcodeGenerator(EncodeTypes.CompactPdf417, "Compact info");
compactGen.Parameters.Barcode.XDimension.Pixels = 4; 

BarcodeGenerator macroGen = new BarcodeGenerator(EncodeTypes.MacroPdf417, "Segmented large dataset");
macroGen.Parameters.Barcode.Pdf417.Pdf417MacroFileID = 123;
macroGen.Parameters.Barcode.Pdf417.Pdf417MacroSegmentID = 1;
macroGen.Parameters.Barcode.Pdf417.Pdf417MacroSegmentsCount = 3;
macroGen.Parameters.Barcode.XDimension.Pixels = 4; 

microGen.Parameters.Barcode.Pdf417.Pdf417Rows = 4;
microGen.Parameters.Barcode.Pdf417.Pdf417Columns = 2;
compactGen.Parameters.Barcode.Pdf417.Pdf417ErrorLevel = Pdf417ErrorLevel.Level2;
macroGen.Parameters.Barcode.Pdf417.Pdf417ErrorLevel = Pdf417ErrorLevel.Level4; ```

### Step 4: Save and Test the Barcode Output

```cs
microGen.Save("micro-pdf417.png", BarCodeImageFormat.Png);
compactGen.Save("compact-pdf417.png", BarCodeImageFormat.Png);
macroGen.Save("macro-pdf417-segment1.png", BarCodeImageFormat.Png);

using Aspose.BarCode.Generation;
using System.Drawing;

class Program
{
    static void Main()
    {
        // Micro PDF417
        BarcodeGenerator microGen = new BarcodeGenerator(EncodeTypes.MicroPdf417, "Micro data");
        microGen.Parameters.Barcode.XDimension.Pixels = 4;
        microGen.Parameters.Barcode.Pdf417.Pdf417Rows = 4;
        microGen.Parameters.Barcode.Pdf417.Pdf417Columns = 2;
        microGen.Save("micro-pdf417.png", BarCodeImageFormat.Png);

        // Compact PDF417
        BarcodeGenerator compactGen = new BarcodeGenerator(EncodeTypes.CompactPdf417, "Compact info");
        compactGen.Parameters.Barcode.XDimension.Pixels = 4;
        compactGen.Parameters.Barcode.Pdf417.Pdf417ErrorLevel = Pdf417ErrorLevel.Level2;
        compactGen.Save("compact-pdf417.png", BarCodeImageFormat.Png);

        // Macro PDF417 (segment 1 of 3)
        BarcodeGenerator macroGen = new BarcodeGenerator(EncodeTypes.MacroPdf417, "Segmented large dataset");
        macroGen.Parameters.Barcode.Pdf417.Pdf417MacroFileID = 123;
        macroGen.Parameters.Barcode.Pdf417.Pdf417MacroSegmentID = 1;
        macroGen.Parameters.Barcode.Pdf417.Pdf417MacroSegmentsCount = 3;
        macroGen.Parameters.Barcode.XDimension.Pixels = 4;
        macroGen.Parameters.Barcode.Pdf417.Pdf417ErrorLevel = Pdf417ErrorLevel.Level4;
        macroGen.Save("macro-pdf417-segment1.png", BarCodeImageFormat.Png);
    }
}

foreach (var doc in documents)
{
    BarcodeGenerator g = new BarcodeGenerator(EncodeTypes.MacroPdf417, doc.SegmentData);
    g.Parameters.Barcode.Pdf417.Pdf417MacroFileID = doc.FileID;
    g.Parameters.Barcode.Pdf417.Pdf417MacroSegmentID = doc.SegmentID;
    g.Parameters.Barcode.Pdf417.Pdf417MacroSegmentsCount = doc.TotalSegments;
    g.Save($"macro_{doc.FileID}_segment{doc.SegmentID}.png", BarCodeImageFormat.Png);
}
