XSane is a graphical scanning frontend for
SANE (Scanner Access Now Easy).
It uses the SANE-library to talk to
scanners. This means that XSane does not support any scanners itself.
Take a look at the
SANE-backends homepage to find out which scanners are supported by SANE.
XSane is designed for acquiring images with scanners (there are other
devices like cameras and videodevices supported by SANE and you will
see that xsane may support some basic functions of those devices, but XSane is
not designed for that purpose).
XSane can do different things with the acquired images:
XSane can also be started from the GIMP as
Gimp plugin.
