something is wrong in this library. #49
Comments
Don't think it's this library, I've had the same issues using pretty much any QR Code styling library. As soon as you change the styling of a QR code even the slightest a lot of web and android based qr code scanners just don't want to scan the code. Interestingly, iOS never has any issues from my testing. |
Столкнулся с той же проблемой. Даже самый простой, совсем не измененный QR код в этой библиотеке - не сканируется. При этом в библиотеке https://kazuhikoarase.github.io/qrcode-generator/js/demo/ он сканируется очень хорошо. В БИБЛИОТЕКЕ ЕСТЬ КРИТИЧЕСКАЯ ОШИБКА! Если ее не исправить, примерно половина распространенных сканеров не смогут расшифровать эти QR-коды. Ошибка в том, что пиксели-точки развернуты не верно, они отображены зеркально и повернуты на 90 градусов, это не правильно. |
На изображении сверху 2 QR кода с одной и той же зашифрованной информацией. Слева, корректный и правильный QR-код, считывающийся всеми сканерами. Справа - QR-Code styling - с ошибкой размещения точек (окрашены бордовым цветом). Видно, что они развернуты не верно. |
@dmitrystas this can be fixed too by the following code, it needs to be fixed in both QRSVG.ts and QRCanvas.ts: WRONG: FIX: |
See fix here: https://github.com/sallandpioneers/qr-code-styling This fork will be maintained until further notice by Salland Pioneers (business). |
Hi @dmitrystas @justraman @HenkVanMaanen @randomprogramming @DewiarQR , sorry for leaving you for so long The fix was released in version v1.7.1 and above. |
this lib is dependent on https://kazuhikoarase.github.io/qrcode-generator/js/demo/.
when I create a QR there it's scannable from all devices and all QR apps.
but when I create the same QR from https://qr-code-styling.com/ without(image and styling) it's not scannable from less popular QR apps.
how this is possible?
reference app for android: https://play.google.com/store/apps/details/?id=com.mrakash.qrcodescanner
ios: Facebook app, QR scanner Pro
