[sane-devel] issue with scanning at higher resolutions

[m. allan noah]

if you scan with a higher dpi, there is more data to display. it may be 
possible for a front-end to be smart enough to scale the image to fit on 
your screen no matter the dpi, but this really has nothing to do with 
sane. i know for instance, that gqview has options to do just this...
