Hi Andrey,
just wanted to let you know that I can confirm that your changes work, I can
now scan perfectly at 100 dpi without any distortions. I also tried playing
around with the parameters for the other resolutions but so far that didn't
yield any sensible results, unfortunately.
Btw, whenever I start xscanimage or xsane, I can also choose 75 dpi as
scan resolution. However, I have checked the Windows driver and it
turns out that on Windows you can only choose 50, 100, 150, 300, 600
and 1200 dpi as resolution. I browsed through the source of the backend
but couldn't find any place where the possible resolutions are defined. But
in any case, 75 dpi should be removed, I think.
Thanks,
Adrian
