 jj2000.j2k.wavelet.WTDecompSpec
| WTDecompSpec | | public class WTDecompSpec (Code) | | This class holds the decomposition type to be used in each part of the
image; the default one, the component specific ones, the tile default ones
and the component-tile specific ones.
The decomposition type identifiers values are the same as in the
codestream.
The hierarchy is:
- Tile and component specific decomposition
- Tile specific default decomposition
- Component main default decomposition
- Main default decomposition
At the moment tiles are not supported by this class.
