[sane-devel] Saphir Ultra II color changes?

Hi Oliver,
sorry I maybe said it somewhat unclear. The rgb-pixels align right - no
geometric shift. The difference from preview to final scan is: I see an
yellowish preview an get an bluish scan. It locks like xsane uses an
other method for preview than for the final scan. I remember to have read
about gammatables in the scanner versus gamma correcting in (x)sane, this
would give an good explanation.
