Generating barcodes in C# Class sample codes:

  // Create a linear object and set barcode symbology type to Code-39
  Linear barcode = new Linear();
  barcode.Type = BarcodeType.CODE39;
        
  // Set barcode value
  barcode.Data = "CODE39";
        
  // Set barcode bar width (X module) and bar height (Y module)
  barcode.X = 1;
  barcode.Y = 60;
        
  // Generate barcode and encode barcode to gif format
  barcode.Format = ImageFormat.Gif;
  barcode.drawBarcode("c#-barcode.gif");
        
  // Print barcode to C# Bitmap object
  Bitmap barcodeInBitmap = barcode.drawBarcode();

Other C# methods to generate barcodes & output to C# objects:

  public void drawBarcode(Graphics graphics);

  public void drawBarcode(string filename);
