How Can I Optimize PDF417 Symbols in my ASP.NET Web Control?

Option #1

Add the following attributes to your TBarCode .NET Web Control. This will generate an optimized symbol, which fits into a 120 x 120 pixel matrix. Increase both the Width/Height and the NumberOfColumns attribute if required.

<cc2:BarcodeControl id="BarcodeControl1"
  Width="120" Height="120"
  Barcode-Dpi="96"
  Barcode-SizeMode="MinimalModuleWidth"
  Barcode-Pdf417-NumberOfColumns="3"
  Barcode-MustFit="True" ErrorHandling="ShowMessage"
  Barcode-BarcodeType="Pdf417"

Option #2

In the Page Load event or after you have set the bar code data apply the following calculation. This code will use width/height ratio of 1:3 for the graphical modules.

Barcode barcode = BarcodeControl1.Barcode;
barcode.SizeMode = SizeMode.FitToBoundingRectangle;
System.Drawing.Size optimalSize = barcode.CalculateOptimalBitmapSize(null, 1, 1);

BarcodeControl1.Width = new Unit(optimalSize.Width, UnitType.Pixel);
BarcodeControl1.Height = new Unit(optimalSize.Height, UnitType.Pixel);

BarcodeControl1.Refresh();
