Class HSBTreeMapColorProvider

java.lang.Object
  net.sf.jtreemap.ktreemap.example.HSBTreeMapColorProvider

All Implemented Interfaces:

ITreeMapColorProvider, org.eclipse.jface.viewers.IColorProvider

public class HSBTreeMapColorProvider
extends java.lang.Object
implements ITreeMapColorProvider

An HSB color space color provider for KTreeMap. Uses a specified function to map the values onto the HSB color space. The default is a linear function, but in my experience one of the logarithmic ones works best for this color space.
