EPC QR Code (European Payments Council) Not Decoded #558

Open SanKumSan opened 3 months ago

SanKumSan commented 3 months ago

We have an EPC QR code and ZXing is not able decode this type of QR code. Does ZXing support or decode EPC QR codes ?

If No, what would be an alternative to Decode (NOT TO GENERATE the QRCode) to use in C# application ?

Thanks

I would assume ZXing.NET can decode EPC QRCodes just fine. Those are standard QRCodes with a simple multi-line text content. Can you give a sample that fails and explain how it fails?

That said, an alternative would be ZXingCpp which can detect those for sure.

Hello axxel,

Thanks for your inputs

I have ZXing.NET version 0.16.6, installed in .Net Framework. 4.6.1 I cannot share the file as it is from the customer, and I have tested it but does not work. with this 0.16.6 version.

Also, what is this alternative you are suggesting. ZXingCpp Is there a difference bw the ZXing.NET and ZXingCpp ? (as i can see, one big diff is System.Drawing)

These both can be used in C#, Net applcations ?

Do you recommend to use ZXingCpp in production Net core C# applications (.Net 8 for example) ? Have you worked with this before ?

ZXingCpp is a thin .NET wrapper around the c++ library zxing-cpp. Some parts of it, including the QRCode detector are completely rewritten from scratch since the project was ported from the Java library many years ago.

Yes.

I am the maintainer of the ZXingCpp wrapper and the zxing-cpp project and therefore biased but I surely believe the code can be used in production. There are quite a few companies using the c++ library or one of the wrappers (like Android and iOS) in production. The "alpha" tag on the .NET wrapper is mostly because I wanted to express the fact that the .NET API might still change if I find an even more idiomatic solution.

If you give it a go and find any issues with it, please report them at the zxing-cpp github project.
