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 Details
-
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 indexc- Component index- Returns:
- true is the data is reversible, false if not.
-
getAnSubbandTree
Returns a reference to the root of subband tree structure representing the subband decomposition for the specified tile-component. -
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.
