Hi Michael,
I agree with you that the scratch removal implementation should be high
on the priority list. I remember having seen outlines of an algorithm,
do you have any need for them?
Five other remarks: on scanner hangs/cancelling, on the model number, on
the READ SETTINGS-command (0xd7), on

sorry for the very late reply. I have been rather busy with different
things and have not done very much on the PIE backend.

Enough stuff to think about. Some reactions and a couple of new topics

So, I guess under Windows shading correction is done in software
