Hi,

Many thanks to Frederic Peters, GNOME Scan ref doc is now at library.gnome.org :  http://library.gnome.org/devel/gnome-scan/0.6/. If you fill adventurous, you could try writing a plugin for you prefered app or write a standalone app on top of GNOME Scan. Beware that API is supposed to change for 0.8, in order to provide bindings (Gobject introspection and vala first, then python and more).

Regards,

Étienne.
