Keep in mind that the 42-bit color figure is referring to a total depth of 42 bits per *pixel*, while the 8 bit color you're seeing is per *channel* (I.E., 24-bits per pixel). You're not missing a huge amount with 24bpp (8bpc), unless you are doing drastic histographic value changes; in 'dat case, the higher bit depth will keep your images from becoming posterized. You'll still need to downgrade to 24bpp or 8bpp to save in most any "standard" format. -- -aardvarko http://aardvarko.com webmaster at aardvarko dot com > -----Original Message----- > From: tclug-list-admin at mn-linux.org > [mailto:tclug-list-admin at mn-linux.org]On Behalf Of andy at theasis.com > Sent: Friday, November 02, 2001 20:30 > To: 'tclug-list at mn-linux.org' > Subject: RE: [TCLUG] usb scanners, xscanimage/gimp
