[borisreitman]

The zbar library supportsdecoding raw bytes qrcode, as described in this pull request, which was also a bug. How to expose this in zbarlight?

Exmaple where it works and doesn't with zimgbar program. The difference is in the binary option:

sslcheck$ zbarimg -q --raw -Sbinary sample-qrcode3.png | hexdump
0000000 05 a0 00 e2 67 86 4b 45 79 ca 9a 38

sslcheck$ zbarimg -q --raw sample-qrcode3.png | hexdump
0000000 05 c2 a0 00 c3 a2 67 c2 86 4b 45 79 c3 8a c2 9a
0000010 38 0a
