Class IndexImage
java.lang.Object
org.apache.batik.ext.awt.image.rendered.IndexImage
This class implements an adaptive palette generator to reduce images to a
specified number of colors.
Ideally this would also support a better dither option than just
the JDK's pattern dither.
The algorithm used is the 'Median Cut Algorithm' published by
Paul Heckbert in early '80s.
