Examples of javax.media.jai.ColorCube

javax.media.jai.ColorCube
A subclass of LookupTableJAI which represents a lookup table which is a color cube. A color cube provides a fixed, invertible mapping between table indices and sample values. This allows the findNearestEntry method to be implemented more efficiently than in the general case.
All constructors are protected. The correct way to create a ColorCube is to use one of the static create methods defined in this class. @see javax.media.jai.LookupTableJAI

                    0, new int[] {2});
            pb.add(colorMap);
