[sane-devel] Problems with gamma

[Tim Hadden]

Hello,

I am trying to figure out how to use the gamma controls from the scanimage
command line utility. I have a hp 4215 MFC any time I try  to put in any of
the options for --custom-gamma=yes it tells me unreconized option. I can set
the gamma in the xsane program I am not sure it this helps at all. I have
searched the internet over for a answer but cannot find the solution.

Thanks for any help you could provide.

Thanks

Tim
