[sane-devel] any drivers do software calibration?

[m. allan noah]

with the adf fujitsu scanners, in grayscale or color, we get fine, lightly 
colored lines as a part of the scanned image, and the 'background' behind 
the document when the scan window exceeeds the size of the paper looks 
mottled gray, as reported on this list.

i can find no way in the interface manual to prevent this in hardware, 
though it has been reported that the same scanners under twain do not 
display these problems.

hence, i assume that this can be corrected in software. are any of the 
existing sane backends doing this internally? i would like to do something 
similar as an option in the fujitsu backend...

thanks,

allan noah
