Can't get Suppliment code

[Eraser]

Hi,

I tested Barcode library for barcode recognition of EAN13 (ISSN) and Supplement. Unfortunately library didn’t recognize supplement barcode. Please see attached image.

I already tested the library year ago and had same problem. I reported about it at the forum: https://www.aspose.com/community/forums/permalink/753425/753425/showthread.aspx#753425

You reported that bug was fixed.

Could you please check it on my example again?

Hi Viacheslav,

Thank you for your inquiry and sharing sample.

We have investigated the issue. It was found that the sample image shared by you contains the supplement barcode but it is blurred and some lines are merged. Due to this reason, Aspose.BarCode is unable to extract the supplement barcode. The issue has been logged into our system with ID BARCODENET-36557. Our product team will further look into it and provide feedback. We will update you with the feedback in this thread once available.

Regarding your previous issue, following code snippet recognizes the barcode and supplement barcode from sample image (PB_2016_06.jpg) successfully.

CODE:

Aspose.BarCode.BarCodeRecognition.BarCodeReader reader =
new Aspose.BarCode.BarCodeRecognition.BarCodeReader(@"_XXXX_OT_2017_22.jpg",
Aspose.BarCode.BarCodeRecognition.DecodeType.EAN13, Aspose.BarCode.BarCodeRecognition.DecodeType.Supplement);

reader.RecognitionMode = Aspose.BarCode.BarCodeRecognition.RecognitionMode.MaxBarCodes;
reader.ChecksumValidation = Aspose.BarCode.BarCodeRecognition.ChecksumValidation.Default;

while (reader.Read())
{
string codeText = reader.GetCodeText();
string codeType = reader.GetCodeType().ToString();
string codeChecksum = reader.GetCheckSum();
Console.WriteLine(codeType + ":" + codeText + "," + codeChecksum);
}
reader.Close();

Hi Ikram,

Thank you very much for test and explanation. I have resaved cover from PDF to JPG with better quality settings, 300 DPI instead of 150DPI. Supplement code successfuly recognized.

Excuse for troubling.

Best regards,

Viacheslav

Hi Ikram,

I continue testing BarCode library with hi-resolution Jpegs (300 dpi). Some supplement codes didn't recognize again. They are not blured so much. Could you please test samples again?

Thank you!
