Examples of ColorMap

bibliothek.gui.dock.common.ColorMap
A map containing several {@link Color}s. A ColorMap is associated with exactly one {@link CDockable}. The colors in the map are used to change the standard colors that normally used for example to paint a title or to draw a tab. The entries of this map can be changed at any time. Changes of any entry in this map will be forwarded instantaneously to the element that uses the entry. @author Benjamin Sigg

This class maps numbers to colors. The colors can include opacities and will get interpolated The colormap can be dynamically changed by adding and removing control points. @author Barry Becker

org.geotools.styling.ColorMap
The ColorMap element defines either the colors of a palette-type raster source or the mapping of fixed-numeric pixel values to colors.
```
 <xs:element name="ColorMap"> <xs:complexType> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element ref="sld:ColorMapEntry"/> </xs:choice> </xs:complexType> </xs:element> 
```
For example, a DEM raster giving elevations in meters above sea level can be translated to a colored image with a ColorMap. The quantity attributes of a color-map are used for translating between numeric matrixes and color rasters and the ColorMap entries should be in order of increasing numeric quantity so that intermediate numeric values can be matched to a color (or be interpolated between two colors). Labels may be used for legends or may be used in the future to match character values. Not all systems can support opacity in colormaps. The default opacity is 1.0 (fully opaque). Defaults for quantity and label are system-dependent. @source $URL$
