Class SqrtColorMapper
java.lang.Object
org.biojava.nbio.structure.gui.util.color.ContinuousColorMapperTransform
org.biojava.nbio.structure.gui.util.color.SqrtColorMapper
- All Implemented Interfaces:
ContinuousColorMapper
Performs a sqrt transform on input before passing the values off to another
colorMapper.
For instance, to map [0^2, 10^2] to a rainbow gradient, use
new LogColorMapper(GradientMapper.getGradientMapper(GradientMapper.RAINBOW_GRADIENT, 0, 10))
