The “Rearrange Colormap” window
This command allows you to re-organize colors in the palette of
indexed images. It doesn't modify the image. You
can't add or remove colors; for that, see
The Indexed Palette Dialog
You can access this command from the image menu-bar through
→ → .
If your image is not indexed, this command is grayed out and disabled.
Using the “Rearrange Colormap” dialog
Explanations supplied in the dialog window are enough: drag
and drop colors to rearrange the colormap. You can sort colors in
various ways by using the local pop-menu that you get by right-clicking:
