Interface InvWTData
- All Known Subinterfaces:
- CBlkQuantDataSrcDec, CBlkWTDataSrcDec, CodedCBlkDataSrcDec
- 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).

getSubbandTree
public SubbandSyn getSubbandTree(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.
- 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.
getPartitionULX
public int getPartitionULX()
- Returns the horizontal coordinate of the origin of the cell and
code-block partition, with respect to the canvas origin, on the
reference grid. Allowable values are 0 and 1, nothing else.
- Returns:
- The horizontal coordinate of the origin of the cell and
code-block partitions, with respect to the canvas origin, on the
reference grid.
getPartitionULY
public int getPartitionULY()
- Returns the vertical coordinate of the origin of the cell and
code-block partition, with respect to the canvas origin, on the
reference grid. Allowable values are 0 and 1, nothing else.
- Returns:
- The vertical coordinate of the origin of the cell and
code-block partitions, with respect to the canvas origin, on the
reference grid.
