public interface InvWTData
extends MultiResImgData

This interface extends the MultiResImgData interface with the methods that are necessary for inverse wavelet data (i.e. data that is the source to an inverse wavlet trasnform).


Method Summary
 int getCbULX()
          Returns the horizontal code-block partition origin.
 int getCbULY()
          Returns the vertical code-block partition origin Allowable values are 0 and 1, nothing else.
 SubbandSyn getSynSubbandTree(int t, int c)
          Returns the subband tree, for the specified tile-component.

Method Detail

getSynSubbandTree

SubbandSyn getSynSubbandTree(int t,
                             int c)
Returns the subband tree, for the specified tile-component. This method returns the root element of the subband tree structure, see 'Subband' and 'SubbandSyn'. The tree comprises all the available resolution levels.

Specified by:
getSynSubbandTree in interface MultiResImgData
Parameters:
t - The index of the tile, from 0 to T-1.
c - The index of the component, from 0 to C-1.
Returns:
The root of the tree structure.

getCbULX

int getCbULX()
Returns the horizontal code-block partition origin. Allowable values are 0 and 1, nothing else.


getCbULY

int getCbULY()
Returns the vertical code-block partition origin Allowable values are 0 and 1, nothing else.
