PktEncoder ( CodedCBlkDataSrcEnc infoSrc, CSJ2K.j2k.encoder.EncoderSpecs encSpec, Coord numPrec, CSJ2K.j2k.util.ParameterList pl ) : System |
Creates a new packet encoder object, using the information from the 'infoSrc' object.

encodePacket ( int ly, int c, int r, int t, CSJ2K.j2k.entropy.encoder.CBlkRateDistStats cbs, int tIndx, CSJ2K.j2k.codestream.writer.BitOutputBuffer hbuf, byte bbuf, int pIdx ) : CSJ2K.j2k.codestream.writer.BitOutputBuffer |
Encodes a packet and returns the buffer containing the encoded packet header. The code-blocks appear in a 3D array of CBlkRateDistStats, 'cbs'. The first index is the tile index in lexicographical order, the second index is the subband index (as defined in the Subband class), and the third index is the code-block index (whithin the subband tile) in lexicographical order as well. The indexes of the new truncation points for each code-block are specified by the 3D array of int 'tIndx'. The indices of this array are the same as for cbs. The truncation point indices in 'tIndx' are the indices of the elements of the 'truncIdxs' array, of the CBlkRateDistStats class, that give the real truncation points. If a truncation point index is negative it means that the code-block has not been included in any layer yet. If the truncation point is less than or equal to the highest truncation point used in previous layers then the code-block is not included in the packet. Otherwise, if larger, the code-block is included in the packet. The body of the packet can be obtained with the getLastBodyBuf() and getLastBodyLen() methods. Layers must be coded in increasing order, in consecutive manner, for each tile, component and resolution level (e.g., layer 1, then layer 2, etc.). For different tile, component and/or resolution level no particular order must be followed.

getPrecInfo ( int t, int c, int r, int p ) : CSJ2K.j2k.codestream.PrecInfo |
Returns information about a given precinct
|
|
reset ( ) : void |
Resets the state of the object to the initial state, as if the object was just created.
|
|
restore ( ) : void |
Restores the last saved state of this object. An IllegalArgumentException is thrown if no state has been saved.
|
|
save ( ) : void |
Saves the current state of this object. The last saved state can be restored with the restore() method.

fillPrecInfo ( int t, int c, int r ) : void |
Retrives precincts and code-blocks coordinates in the given resolution, component and tile. It terminates TagTreeEncoder initialization as well.
