In kinda sorta related news, here's my super lame QR decoder one liner. It
takes a screenshot and looks for a qr code (actually for many bar code
formats) and then spits the results in a zenity window. Dependencies: scrot,
zbar-tools, zenity.
scrot /tmp/scrot_'%s.png' -e 'zbarimg -q $f|sed s/QR-Code://|zenity
--text-info --title="zbarimg-zenity output" --height 250 --width 400;rm -f
$f'
(Public domain)
So, if you see a large enough, high quality bar code on your screen that
happens to be known to zbarimg, the command should produce the decoded
string. I have that on a hotkey. Since I mostly stumble upon QR codes, I
added that sed replacement bit to remove the QR prefix.
