Dieses Plugin ersetzt die Farben des Bildes durch die Farben der aktiven Palette, die Sie über Dialoge → Paletten auswählen können.

It maps the contents of the specified drawable (layer, selection...) with the active palette. It calculates luminosity of each pixel and replaces the pixel by the palette sample at the corresponding index. A complete black pixel becomes the lowest palette entry, and complete white becomes the highest. Works on both Grayscale and RGB images with or without alpha channel.

This filter is found in the image window menu under Colors → Map → Palette Map.
