Our UMAX Astra 1200S scans much too dark. So, do I need to use a brighten
keyword with xscanimage, or do I need to use custom gamma tables, or what?

Can I use loadable Gamma Tables? In other words is there a way to save a
gamma table in a file, and then load it as the default gamma table?

Or should I do all of this with the brightness command line option (is
this even available for xscanimage?) If someone knows just where I should
look for answers to these questions, I would appreciate the pointer.

Hans

PS, how do you use command line arguments with xscamimage with gimp?
