I've tested the code with TPU and 3200 dpi (where I noticed a slight
vertical banding at high contrast enhancements before the code change).
It works well, at least I hear the scanner doing the calibration and the
resulting image is better than without (banding almost invisible).
Ah yes, and 16 bpp colour at 3200 dpi works equally well!
Thanks for your efforts!
PS: today evening, I'm planning to run some thorough tests. Which
resolution/bit depth/size combinations should I try?
