From time to time i come across QR codes in web pages or PDF documents. It would be nice to have a semi-automatic user friendly :-) QR code recognition in the desktop environment. It seems to me that this could be done as an enancenment to xfce4-screenshooter: just grab a screen region, window, etc., and offer "Recognize barcodes/QRcodes" option besides the Save, Open with, Host on ... options. The recognition itself could be done using the zbarimg(1) utility. Thanks for considering this enhancement.
I don't know, it's a nice feature, but I think it's outside *screenshooter* scope and against the idea of tools that do one thing and do it well. Maybe a panel plugin for that would more suitable. I won't dismiss the idea, but I won't promise to implement this either, patches more welcome.
Now that I'm considering custom actions (to be implemented after 1.9.2), this feature could be achievable with a user provided script, i.e. the user selects the region of the QR code, chooses the "Read QR" custom action that calls a script which will pass the image to zbarimg and saves the result into clipboard.
