extends ImgData
```
This interface extends the ImgData interface with methods that are necessary for forward wavelet data (i.e. data that is produced by a forward wavelet transform).

- Method Detail
  - isReversible
```
boolean isReversible(int t,
                     int c)
```
    Returns the reversibility of the given tile-component. Data is reversible when it is suitable for lossless and lossy-to-lossless compression.
    
    Parameters:
    
    t - Tile index
    
    c - Component index
    
    Returns:
    
    true is the data is reversible, false if not.
  - getAnSubbandTree
```
SubbandAn getAnSubbandTree(int t,
                           int c)
```
    Returns a reference to the root of subband tree structure representing the subband decomposition for the specified tile-component.
    
    Parameters:
    
    t - The index of the tile.
    
    c - The index of the component.
    
    Returns:
    
    The root of the subband tree structure, see Subband.

  - getCbULX
```
int getCbULX()
```
    Returns the horizontal offset of the code-block partition. Allowable values are 0 and 1, nothing else.
  - getCbULY
```
int getCbULY()
```
    Returns the vertical offset of the code-block partition. Allowable values are 0 and 1, nothing else.
