Failed to decode QR code.

[yapzhenyie]

I'm facing one issue where the qrcode library not able to decode the below qrcode image.

I tried decode in some other websites or even using my phone qr code scanner. It was able to decode, but @nuintun/qrcode library not.

The QR code decoding does not perform extensive image preprocessing for performance considerations.

The example image you provided has too high a resolution, resulting in imperfections in the image after binarization.

You can try resizing the image to an appropriate size before decoding.
