As Mattias already daid: this is not a problem. If it had been a problem,
SANE users would have cried out loudly years ago :-)

scanimage prints the backend-privided values. Try e.g.
scanimage -d test --help

As far as I can see, option mode is no special option in scanimage.

That's a good idea. There is already a proposal for this in the SANE 2
standard draft:
http://www.sane-project.org/sane2/0.08/doc014.html#s4.5.6

I'd just use these values and add them to saneopts.h (after the freeze).

Do we really need Color Lineart (or Lineart Color)? Better don't
mention that crazy mode anywhere :-)

Bye,
