Quantize Color Plugin for the GIMP
My first plugin for the Gimp is a port from a plug-in for
Gimp 0.54, quant.c.
The plug-in is building a color map with a given Number of colors
and changes the colors in the image to the new color-map.
The difference to the <Image>/Indexed Gimp-builtin is the algorithm.
With few colors the results are much better. The Author of the
original plug-in, Matthias Clasen, made a comparison - unfortunately
no longer available on the Web. I will do
my own, when there is some time over... :-)
The algorithm is (nearly) untouched. I just ported the plug-in interface.
I finally changed it to use the tile-based architecture of the Gimp -
it is now four times faster :-)
OK. Here is the code quant.c.
Any suggestions to Simon Budig
