I've done some tests with my scanner (Hewlett-Packard ScanJet 2300c)
and xsane or xscanimage.
I found xsane more user-friendly, but now I note that with some
images, results from xsane are not usable, while xscanimage can
handle such tricky cases.
Particularly, I can'nt get soft-toned images at 1200 dpi with xsane:
all that i get is a sharp black and white-only image.
In case it can be interesting for developpers, I've uploaded some
example_xscanimage_300dpi.pnm with default gamma
example_xscanimage_600dpi_b.pnm with custom gamma, better
example_xscanimage_1200dpi.pnm with default gamma
example_xscanimage_1200dpi_b.pnm with custom gamma
I was surprised that a correct gamma at 300dpi becomes too dark at 600
and more, and it was necessary to lighten the loud keys.
example_xsane_1200dpi.pnm (all with same setting, see gamma_xsane.png)
