QR not scanable if x and y modules are swapped

Open FelixBurkhard opened this issue 4 years ago • 2 comments

Is your feature request related to a problem? Please describe. I am working on a project where we use qrCode-svg to create a QR Code which we later scan again thanks to this great project. Unfortunatly I was not able to scan the created QR Code with ngx-scanner while it there were not problems with other scanners. After a while I figured out that I needed to set the swap option. I am not sure what excatly it does since I am not really familiar with QR Codes but it looks like it just mirrors the the code along an axis from top left to bottom right.

Describe the solution you'd like It would be best if ngx-scanner were able to read the QR Code independent of the x-y modules.

Describe alternatives you've considered As a 'quickfix' I propose you could add this information to the limitations of the wiki so its easy to find.

Additional context

This is not scanable: notWorking This is scanable: works

Hello! It should not be a limitation at all, we are actually facing some instability in the QR code and PDF417 readers in which I gonna work in the next weeks. Thanks for getting in touch guys.
