I've got the AdobeICCProfiles-2.0-31 rpm installed which provides quite a few ICC profiles. convert rgb_file.jpg -profile path/to/srgb.icm -profile path/to/cmyk.icc cmyk_file.jpg You can also use the utilities from the liblcms package as well. "jpegicc" and "icctrans" come to mind. http://www.littlecms.com good luck, brian -- Brian Jackson Action Athletics Sports Photography http://www.ActionAthletics.com/ _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
