public class TLcdIndexColorModel extends IndexColorModel
Extension of IndexColorModel that takes a TLcdColorMap to define the coloring.

Important notice: the package com.luciad.imaging presents a new API for the modeling of raster data. For new projects, it is recommended to use this API instead of ILcdRaster et al. You can set the TLcdColorMap directly on the painter or styler or use TLcdIndexLookupOp to manually map values to colors.

It will use retrieveColor on the given TLcdColorMap for every possible (integer) level to define the exact coloring. The levels of the given TLcdColorMap will be converted to raster values using the configured configured raster value converter, or simply interpreted as integers if no converter is present. All level values that are outside the valid range (TLcdColorMap.getLevelInterval()) will be completely transparent.

The TLcdColorMap used to construct the TLcdIndexColorModel can be retrieved later on using getColorMap(). This allows to create a new TLcdIndexColorModel that is slightly different from a given TLcdIndexColorModel. For example, 


 TLcdColorMap color_map = ( TLcdColorMap ) given_index_color_model.getColorMap().clone();

 //make modifications to the color map
 color_map.setColor( 0, Color.blue );

 //create slightly modified index color model
 modified_index_color_model = new TLcdIndexColorModel( given_index_color_model,color_map )
As its superclass, this TLcdIndexColorModel cannot be changed after it is constructed. Therefore one should not modify the properties of the TLcdColorMap after it is given to the constructor, nor should one modify the TLcdColorMap returned by getColorMap().
