- org.biojava.nbio.structure.gui.util.color.ContinuousColorMapperTransform
- - org.biojava.nbio.structure.gui.util.color.SqrtColorMapper

All Implemented Interfaces:

ContinuousColorMapper
```
public class SqrtColorMapper
extends ContinuousColorMapperTransform
```
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))
