Class PrecinctSizeSpec
java.lang.Object
jp2codec.ModuleSpec
jp2codec.entropy.PrecinctSizeSpec
public class PrecinctSizeSpec
- extends ModuleSpec
This class extends ModuleSpec class for precinct partition sizes holding
purposes.
It stores the size a of precinct when precinct partition is used or not.
If precinct partition is used, we can have several packets for a given
resolution level whereas there is only one packet per resolution level if
no precinct partition is used.

PrecinctSizeSpec
public PrecinctSizeSpec(int nt,
int nc,
byte type,
IntegerSpec dls)
- Creates a new PrecinctSizeSpec object for the specified number of tiles
and components.
- Parameters:
nt
- The number of tilesnc
- The number of componentstype
- the type of the specification module i.e. tile specific,
component specific or both.dls
- Reference to the number of decomposition levels
specification
getPPX
public int getPPX(int t,
int c,
int rl)
- Returns the precinct partition width in component 'n' and tile 't' at
resolution level 'rl'. If the tile index is equal to -1 or if the
component index is equal to -1 it means that those should not be taken
into account.
- Parameters:
t
- The tile index, in raster scan order. Specify -1 if it is not
a specific tile.c
- The component index. Specify -1 if it is not a specific
component.rl
- The resolution level
- Returns:
- The precinct partition width in component 'c' and tile 't' at
resolution level 'rl'.
getPPY
public int getPPY(int t,
int c,
int rl)
- Returns the precinct partition height in component 'n' and tile 't' at
resolution level 'rl'. If the tile index is equal to -1 or if the
component index is equal to -1 it means that those should not be taken
into account.
- Parameters:
t
- The tile index, in raster scan order. Specify -1 if it is not
a specific tile.c
- The component index. Specify -1 if it is not a specific
component.rl
- The resolution level.
- Returns:
- The precinct partition width in component 'n' and tile 't' at
resolution level 'rl'.
