Skewed (trapezoid) photo of QR code w/ surroundings not recognized and decoded

[JayBrown]

I did a test with a skewed image (trapezoid), a QR code on a computer screen shot with a phone: qrscan will not recognize the QR code, probably because of the surroundings, because when I crop the image to remove those, the QR code is recognized & decoded fine.

Lower part of the original image:

Commands:

As you can see, cropping does the trick with qrscan… and zbarimg doesn't work in either case.

PS: lower part of the image after cropping, but still skewed:

Thanks for reporting. I'm afraid this might be the best qrscan's core scanning library, rqrr can do, unless there's some optimization option I'm missing. Or we can explore better alternatives. I'm currently off on side projects, so I'll leave this issue open until I'm back, or someone else finds a good solution.
