All Implemented Interfaces:
Cloneable
public class CRNGColorCycle extends ColorCycle
Implements CRNG and CCRT color cycling for an IFF ILBM image.

This class supports CRNG and CCRT color cycling as published in AMIGA ROM Kernel Reference Manual: Devices, Third Edition, Addison-Wesley, Reading ISBN 0-201-56775-X
