--- Comment #5 from gr...@kde.org --- I thought -- remember from some earlier testing -- that black pixels were OK, but blue was not. I can't get it to work with any of these images now, though. As an example, `kodaskanna qr-black-sharp.png` prints no output, the display is "could not scan code in the image". This is with zxing-cpp-1.2.0 ZXing C++ Library for QR code recognition FWIW, qtqr (just some random python-and-qt tool I found for QR-encoding and decoding) does decode all four of these codes, and produces the attached qr-black-alt.png for the same URL -- and **that** is one that kodaskanna can deal with. One out of five ain't bad. -- You are receiving this mail because: You are watching all bug changes.
