That would make sense. Being a single-pass scanner, the R, G and
B sensors can't possibly be in the same horizontal position, can
they? I would expect the scanner firmware to realign the
channels before sending data off to the host, though. Anyway, it
should be easy enough to fix in gimp...
By now you can probably tell that I'm an absolute scanning
newbie. Anyway, I'm going to experiment with this in detail, but
at the moment I'm struggling with more basic problems.
Cheers
