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))
