In the Color Map Assignment dialog box, do one of the following:
For a palette color map, use the drop-down list to select a color map. If you want to edit, copy, or create a new color map, click the appropriate button to the right of the list, then use the Palette Color Map Definition dialog box to make changes. If you do not want to insert the image into the display, clear the Insert Into Display check box.
