Some QR codes cannot be recognized

Aspose.BarCode Product Family

Hi there.


We have problem recognizing some of QR codes that we are printing ourselves using BarCode.
Attached please find 6 samples. From the file names you will understand which ones are recognized and which ones are not. Looking at these samples with eyes - not clear why it happens. It seems all they should have been recognized.

Thank you for the help you can give us - it’s creating a lot troubles.

p.s. Having paid for Developer Small Business license, not sure why I can’t access priority support forum.

Hello Oleksandr.

Aspose.BarCode 5.8 (which is near to be published) can recognize 5 of 6 pictures.
UnRecognized2.jpg is still the problem.
You can see the upper part of the picture is cut off.
I have attached an edited image with this barcode which is recognized fine.

Issue of UnRecognized2.jpg is clear - that is not a problem.

Please let me know when the new version will be available?

According to my expectations the release will be published this or next week

Hi Oleksandr,

Thank you for your inquiry. I tested your sample bar code images against the latest build of Aspose.BarCode for .NET 5.7.0.0. It can also recognize 5 of 6 images. You can download it from here.

string[] files = Directory.GetFiles(folderPath);

foreach (string file in files)

{

using (BarCodeReader reader = new BarCodeReader(file, BarCodeReadType.QR))

{

while (reader.Read())

{

Console.WriteLine(Path.GetFileName(file) + "--Symbol:" + reader.GetReadType() + " Code :" + reader.GetCodeText());

}

}

}

Result:

Recognized1.jpg–Symbol:QR Code :2013/801961

Recognized2.jpg–Symbol:QR Code :2013/801955

Recognized3.jpg–Symbol:QR Code :2013/802400

UnRecognized1.jpg–Symbol:QR Code :2013/801958

UnRecognized3.jpg–Symbol:QR Code :2013/801084

Please do let me know in case of any confusion or questions.

Hi Oleksandr,


Thank you for your reply. I added Aspose.BarCode 5.8.0.0 as a new release. I mean to say the previous releases are also available in descending order. Anyway, please feel free to ask if you have any question regarding Aspose products, we will be happy to help you.

Dear Imran,


Thank you for your comments. All those previous examples are okay with the version 5.8 (except one that was cropped). But I found another one that still cannot be recognized, although it was generated with Aspose components.
It’s attached with this reply.

Please let me know if you can help somehow.

Thank you.
