Class ColorMap

java.lang.Object

sgtplot.ColorMap

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.io.Serializable, java.lang.Cloneable, java.util.EventListener

Direct Known Subclasses:

CLIndexedColorMap, CLTransformColorMap, IndexedColorMap, TransformColorMap

public abstract class ColorMap
extends java.lang.Object
implements java.lang.Cloneable, java.beans.PropertyChangeListener, java.io.Serializable

ColorMap provides a mapping from an index or value to a Color. Several methods of mapping an index or value to a Color are summarized below.

IndexedColorMap

Color is determined from an array, the index computed from a Transform.

TransformColorMap

Red, green, blue Color components are computed from Transforms.

CLIndexedColorMap

Color is determined from and array, the index computed from a ContourLevels object.

CLTransformColorMap

Red, green, blue Color components are computed from Transforms, using the index computed from a ContourLevels object divided by the maximum index value.

Since:

1.0
