Class ProgressionSpec

java.lang.Object

jj2000.j2k.ModuleSpec

jj2000.j2k.entropy.ProgressionSpec

All Implemented Interfaces:

Cloneable

public class ProgressionSpec
extends ModuleSpec

This class extends ModuleSpec class for progression type(s) and progression order changes holding purposes.

It stores the progression type(s) used in the codestream. There can be only one progression type or several ones if progression order changes are used (POC markers).

Constructor Detail

ProgressionSpec

public ProgressionSpec(int nt,
                       int nc,
                       byte type)

Creates a new ProgressionSpec object for the specified number of tiles and components.

Parameters:

nt - The number of tiles

nc - The number of components

type - the type of the specification module i.e. tile specific, component specific or both. The ProgressionSpec class should only be used only with the type ModuleSpec.SPEC_TYPE_TILE.

ProgressionSpec

public ProgressionSpec(int nt,
                       int nc,
                       int nl,
                       IntegerSpec dls,
                       byte type,
                       J2KImageWriteParamJava wp,
                       String values)

Creates a new ProgressionSpec object for the specified number of tiles, components and the J2KImageWriteParamJava instance.

Parameters:

nt - The number of tiles

nc - The number of components

nl - The number of layer

dls - The number of decomposition levels specifications

type - the type of the specification module. The ProgressionSpec class should only be used only with the type ModuleSpec.SPEC_TYPE_TILE.

wp - The J2KImageWriteParamJava instance

Method Detail

checkProgMode

private int checkProgMode(String mode)

Check if the progression mode exists and if so, return its integer value. It returns -1 otherwise.

Parameters:

mode - The progression mode stored in a string

Returns:

The integer value of the progression mode or -1 if the progression mode does not exist.
