Like Niels said, save as MIF, open and save back as FM. Or if you have FrameScript, the ReplaceColors script will remove any unused colors in the doc.
You can prevent this problem from arising in the first place by making sure your graphics use a 24- or 32-bit color depth, 16.7 million colors. It has been demonstrated that PNG files using a lower color depth, equipped with a color palette, add their color palette to the FM list of colors. Never use 2-, 8- or 16-bit color depth graphics in a Frame document and you'll be fine. --Doug On 3/21/06, Melanie Raney <raney at earthdecision.com> wrote: > Anybody know an easy and quick way to delete several color definitions > from a document at once?
