Hi. I created a little tool that creates a gamma table for scanimage: Usage: gamma4scanimage gamma [shadow [highlight [maxin [maxout]]]]
the output that it creates looks like this: $ gamma4scanimage 1.8 0 1023 1023 255 [0]0-[4]11-[6]14-[9]18-[13]22-[20]28-[30]35-[45]44-[68]56-[102]70-[153]88-[230]111-[345]139-[518]174-[778]219-[1023]255-[1023]255 To use it with scanimage simply do something like that: scanimage -l 100 -x 140 -t 110 -y 100 --custom-gamma=yes --gamma-table `./gamma4scanimage 1.6 100 800 1023 255` >image.pnm I hope the program is usefull for some people, I found it ugly to create gamma tables by hand. I added the file to the sane cvs in sane-backends/tools.
