Constructor Detail

CBlkSizeSpec

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

Creates a new CBlkSizeSpec 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.

CBlkSizeSpec

public CBlkSizeSpec(int nt,
                    int nc,
                    byte type,
                    J2KImageWriteParamJava wp,
                    String values)

Creates a new CBlkSizeSpec object for the specified number of tiles and components and the ParameterList instance.

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.

imgsrc - The image source (used to get the image size)

pl - The ParameterList instance

Method Detail

getMaxCBlkWidth

public int getMaxCBlkWidth()

Returns the maximum code-block's width

getMaxCBlkHeight

public int getMaxCBlkHeight()

Returns the maximum code-block's height

getCBlkWidth

public int getCBlkWidth(byte type,
                        int t,
                        int c)

Returns the code-block width :

• for the specified tile/component
• for the specified tile
• for the specified component
• default value

The value returned depends on the value of the variable 'type' which can take the following values :

• SPEC_DEF -> Default value is returned. t and c values are ignored
• SPEC_COMP_DEF -> Component default value is returned. t value is ignored
• SPEC_TILE_DEF -> Tile default value is returned. c value is ignored
• SPEC_TILE_COMP -> Tile/Component value is returned.

Parameters:

type - The type of the value we want to be returned

t - The tile index

c - the component index

Returns:

The code-block width for the specified tile and component

getCBlkHeight

public int getCBlkHeight(byte type,
                         int t,
                         int c)

Returns the code-block height:

• for the specified tile/component
• for the specified tile
• for the specified component
• default value

The value returned depends on the value of the variable 'type' which can take the following values :

• SPEC_DEF -> Default value is returned. t and c values are ignored
• SPEC_COMP_DEF -> Component default value is returned. t value is ignored
• SPEC_TILE_DEF -> Tile default value is returned. c value is ignored
• SPEC_TILE_COMP -> Tile/Component value is returned.

Parameters:

type - The type of the value we want to be returned

t - The tile index

c - the component index

Returns:

The code-block height for the specified tile and component
