I've taken a look and unfortunately there's no way I can use it. I need the program to run under Win32 with as few dependencies as possible, and I cannot translate a 100's lines long Bash program and one that makes many calls to "convert" to something more Windows friendly. I'd rather use gimp-console instead if that's all I can. > In IM, you can control the brightness using the -modulate function > (as well as saturation and hue) and IM also has a -contrast function. > (My script however, does not use either, but goes at it a more direct > way by building a lookup table to adjust brightness and contrast) > > see http://www.imagemagick.org/script/command-line-options.php > I find the relevant documentation confusing. I'd like a more specific answer please.
