Re: [Gimp-user] Reduce the number of colors on a selection
Maybe this: 1. Copy your selection 2. Edit->Paste as New 3. Image->Mode->Indexed 4. Image->Mode-RGB 5. Select All 6. Copy 7. Paste back into original image I used to do something similar in Photoshop when I wanted to bitmap just a portion of an image.

Hi vt, thanks for the reply.

Anyway, I'm unable to find a suitable equivalence from number of colors on indexed to number of levels on posterize, some doc?
