Hello, I use scanner Fujitsu FI-5220C and it works fine.
/usr/bin/scanadf --mode Gray --resolution 150 --source "Flatbed" -e 1 -s 1 -o foo.pnm -v scanadf: scanning image of size 1275x1650 pixels at 8 bits/pixel scanadf: acquiring gray frame scanadf: min/max graylevel value = 13/255 Scanned document foo.pnm Scanned 1 pages But I tried to modify the white point of scanned pages. But the option "threshold", given by the help (scanadf --help -d fujitsu) is not recognized. /usr/bin/scanadf --mode Gray --resolution 150 --source "Flatbed" -e 1 -s 1 -o foo.pnm --threshold 100 -v /usr/bin/scanadf: unrecognized option `--threshold' So what is the right way to manipulate the brightness of scanned pages? with kind regards.
