Failure reading QrCode


I can’t read this QrCode attached but the same can be read using Apps in the my smartphone for example, so it’s not broken.

Could you guys please help me?


Just adding more information:

This image was generated using Aspose PDF, more specifically this code:


The source PDF was a scanned one, so the image is not perfect, but is quite alright for my apps of QrCode recognition.

I’m wondering if there is a way to improve the quality of the generated image. I am facing this issue for months, I would like a solid way to scan for QrCodes!
