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.
Here you can find out
which scanners are supported by the SANE-library.
XSane is designed for acquiring images with scanners (there are other
devices like cameras and videodevices supported by SANE, but XSane is
not designed for that purpose). You can scan to file, do a photocopy,
create a fax and start XSane from the GIMP as gimp plugin.
