Comment créer un bitmap Code 39 lisible ?

L'exemple de code suivant en ASP .NET génère une image Code 39.

//Code 39
Barcode barcode = new Barcode();
barcode.Data = "10030000007611107871900002199908";
barcode.BarcodeType = BarcodeType.Code39;

// with dpi = 100 we get 1 Pixel = 0.254 mms
barcode.Dpi = 100;

// bar code size should adapt to bounding rectangle
barcode.SizeMode = SizeMode.FitToBoundingRectangle;

// set default size of symbol (define the default height)
barcode.BoundingRectangle = new Rectangle(0, 0, 254, 100 /* = 1 inch */);

// now calculate optimal bitmap size for the bar code
Size optimalSize = barcode.CalculateOptimalBitmapSize(null, 1, 1);

// update rectangle to optimized size
barcode.BoundingRectangle  = new Rectangle(0, 0, optimalSize.Width, optimalSize.Height);
barcode.Draw(filename, ImageType.Jpg);
