BarcodeRecognition PDF 417

Aspose.BarCode Product Family

Hi, I have a problem with barcode pdf 417 reader on drivers license. When I am trying to read from it. Response has extra strings like
DCB, DCD, DCS etc. embedded along with the data.

How can we get rid of these strings?

I am using full license.

This is code:
Byte[] bitmapData = Convert.FromBase64String(dlbackstring);
MemoryStream streamBitmap = new MemoryStream(bitmapData);
Bitmap bitImage = new Bitmap((Bitmap)Image.FromStream(streamBitmap));

            // Initialize the BarCodeReader 
            BarCodeReader reader = new BarCodeReader(bitImage, BarCodeReadType.Pdf417);

            // Call Read() method in a loop
            while (reader.Read())
            {
                dlbackdesc.Append(reader.GetCodeText());
            }


            reader.Close();

Output I am receiving from reading barcode:

@mfiroved,

We have further investigated the issue in detail. It was found that there is no issue with the Aspose.BarCode functionality. The data in the driver license has a particular format and it depends from country to country and state to state. For this particular format we have devised a parser. Parser code file is attached for your reference. You may use the parser along with following code snippet to read barcode from license file shared by you.
