Read the docs and you will soon know more than me: For instance, I just went poking around and found out that the GIF format uses LZW compression. Just converting to an indexed format would not compress an image /nearly/ as much as doing that /then/ squashing it with LZW. But not knowing that has not prevented me from using the format successfully, in its proper place (animated dealie-bobs for websites, ror instance), for a loooong time. This stuff is actually simple, from a practical end-user point of view. ;o) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
