#98 zbarimg no flag to inhibit code type output

[Paul Meckel]

The issue

zbarimg quiet output isn't quiet.
When generating a QR code and then decoding it, I expect the same output as the input. However zbarimg outputs QR-Code: in front of the actual data even with -q --verbose=0. No other flags exist to inhibit this output.

Reproduce

qrencode "Hello" -o hello.png
zbarimg -q --verbose=0 hello.png

Expected

Hello

Actual

QR-Code:Hello
