Class ContinuousColorMapperTransform

java.lang.Object
org.biojava.nbio.structure.gui.util.color.ContinuousColorMapperTransform
All Implemented Interfaces:
ContinuousColorMapper
Direct Known Subclasses:
LogColorMapper, SqrtColorMapper
public abstract class ContinuousColorMapperTransform extends Object implements ContinuousColorMapper
Maps colors by performing a transform of the input data and then passing the transformed value to a ContinuousColorMapper for rendering. For instance, to map [10^0, 10^10] to a rainbow gradient, use new LogColorMapper(GradientMapper.getGradientMapper(GradientMapper.RAINBOW_GRADIENT, 0, 10))
