LogColorMapper (biojava 5.2.0 API)

java.lang.Object
- org.biojava.nbio.structure.gui.util.color.ContinuousColorMapperTransform
- - org.biojava.nbio.structure.gui.util.color.LogColorMapper

All Implemented Interfaces:

ContinuousColorMapper
```
public class LogColorMapper
extends ContinuousColorMapperTransform
```
Performs a log10 transform on input before passing the values off to another colorMapper. For instance, to map [10^0, 10^10] to a rainbow gradient, use new LogColorMapper(GradientMapper.getGradientMapper(GradientMapper.RAINBOW_GRADIENT, 0, 10))
