Class InverseColorMapOp

Object

InverseColorMapOp

All Implemented Interfaces:

BufferedImageOp

public final class InverseColorMapOp
extends Object
implements BufferedImageOp

This class provide an Image oriented interface for the EfficientInverseColorMapComputation. Specifically, it is designed in order to implement the BufferedImage for processing BufferedImages efficiently accessing the raster pixels directly but it also provide a method to process general RenderedImages implementations.
