AnWTFilterSpec
public AnWTFilterSpec(int nt, int nc, byte type, QuantTypeSpec qts, J2KImageWriteParamJava wp, String values) Constructs a new 'AnWTFilterSpec' for the specified number of components and tiles.- Parameters:
nt- The number of tilesnc- The number of componentstype- the type of the specification module i.e. tile specific, component specific or both.qts- Quantization specifications

getWTDataType
public int getWTDataType(int t, int c) Returns the data type used by the filters in this object, as defined in the 'DataBlk' interface for specified tile-component.- Parameters:
t- Tile indexc- Component index- Returns:
- The data type of the filters in this object
- See Also:
-
getHFilters
Returns the horizontal analysis filters to be used in component 'n' and tile 't'.The horizontal analysis filters are returned in an array of AnWTFilter. Each element contains the horizontal filter for each resolution level starting with resolution level 1 (i.e. the analysis filter to go from resolution level 1 to resolution level 0). If there are less elements than the maximum resolution level, then the last element is assumed to be repeated.
- Parameters:
t- The tile index, in raster scan orderc- The component index.- Returns:
- The array of horizontal analysis filters for component 'n' and tile 't'.
-
getVFilters
Returns the vertical analysis filters to be used in component 'n' and tile 't'.The vertical analysis filters are returned in an array of AnWTFilter. Each element contains the vertical filter for each resolution level starting with resolution level 1 (i.e. the analysis filter to go from resolution level 1 to resolution level 0). If there are less elements than the maximum resolution level, then the last element is assumed to be repeated.
- Parameters:
t- The tile index, in raster scan orderc- The component index.- Returns:
- The array of horizontal analysis filters for component 'n' and tile 't'.

isReversible
public boolean isReversible(int t, int c) Check the reversibility of filters contained is the given tile-component.- Parameters:
t- The index of the tilec- The index of the component
