Class Progression

java.lang.Object

jj2000.j2k.entropy.Progression

All Implemented Interfaces:

ProgressionType

public class Progression
extends Object
implements ProgressionType

This class holds one of the different progression orders defined in the bit stream. The type(s) of progression order are defined in the ProgressionType interface. A Progression object is totally defined by its component start and end, resolution level start and end and layer start and end indexes. If no progression order change is defined, there is only Progression instance.
