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 indexc
- 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.
-
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.
