[sane-devel] Distortion of pictures scanned using canoscan n1220u and latest plustek backend

[m. allan noah]

out of proportion images usually are because you requested a resolution 
that the scanner does not physically support in one of it's two 
directions. i dont know if this is the case in your scanner, since i dont 
have one, but it is certainly the case for older scanners from several 
different brands that i have used. 

try turning on debugging for your scanner from the command line, and look 
at the output during a small scan. see if it says anything about rounding 
the x or y resolution value.
