Colours adjustment with `sane'
I got not sufficient help from the `sane' mailing list about this problem: I
don't manage to properly adjust colours when scanning a photo with `sane'. In
particular, I want to diminish the red colour from a photo, but with the
--red-gamma-table option all I get is that red turns to grey and grey turns to
red! Whereas the --gamma-table option is inactive and I don't manage to
activate it.
Anybody on this list who has experience with this matter? Or maybe adjust
colours with another application?
Thanks,
Rodolfo
