The calling code is:

Code128 _code = new Code128 () _code.valuefont = new Font ("Arial", 20); System.Drawing.Bitmap imgtemp = _code.getcodeimage ("t26200-1900-123-1-0900", Code128.Encode.Code128A); imgtemp.save (System.AppDomain.CurrentDomain.BaseDirectory + "\" + "Barcode.gif", System.Drawing.Imaging.ImageFormat.Gif);
