When I try to create a Pdf417 barcode, I get a black rectangle. I can't figure out what values I need to set and nothing is documented. Would someone post a sample that shows how to create a Pdf417 barcode? Extra credit if the fields are explained.

Thanks.

Hi,

Thanks for using our component.
Please try the following code.
Code: Select all
 string id = "123456";
            BarcodeSettings setting = new BarcodeSettings();
            setting.Data2D = id;
            setting.Data = id;
            setting.Type = BarCodeType.Pdf417;

            setting.ShowText = false;

            BarCodeGenerator generator = new BarCodeGenerator(setting);

            Image barcode = generator.GenerateImage();

            barcode.Save(@"barcode2.png",System.Drawing.Imaging.ImageFormat.Png);


Best Regards,
