Indexing without mode change
Submitted by david gowers
Link to original bug (#141249)
Description
the idea is to preserve the image mode (RGB/Greyscale) and just modify the color data. for most kinds of indexization this is effective. (the only case i know where it is not is when you want two palette entries the same color in your palette -- for instance for color-cycling effects)
making indexization into a filter could address these bugs:
- #52123 : option to indexize images with palettes > 256 colors
- #88361 : use marked area for creation of palette
- #66258, #66261 : colors that should not be (dithered/ modified) during indexization.
i find i often want to indexize only part of an image; this would also resolve that problem which i currently have to work around.
