[sane-devel] TPU negatives scan for Canon CS8800F and CS9000F

[Rolf Bensch]

Hi list,

I disabled TPU negatives scan for Canon for CS8800F and CS9000F with my
last commit.

I received some feedback, that negatives scan confuses the users.

The only difference between positives and negatives scan is one byte in
the protocol. I didn't found any visual difference between the scanned
images.

Anyway, converting negatives is part of the frontend (e.g. xsane) or
another external application.

Cheers,
Rolf
