CSJ2K.j2k.entropy.encoder.CodedCBlkDataSrcEnc

CodedCBlkDataSrcEnc Interface

This interface defines a source of entropy coded data and methods to transfer it in a code-block by code-block basis. In each call to 'getNextCodeBlock()' a new coded code-block is returned. The code-block are retruned in no specific-order.

       <p>This interface is the source of data for the rate allocator. See the
       'PostCompRateAllocator' class.</p><p>For each coded-code-block the entropy-coded data is returned along with
       the rate-distortion statistics in a 'CBlkRateDistStats' object.</p>

Methods

Name Description
getNextCodeBlock(int, CBlkRateDistStats)

Returns the next coded code-block in the current tile for the specified component, as a copy (see below). The order in which code-blocks are returned is not specified. However each code-block is returned only once and all code-blocks will be returned if the method is called 'N' times, where 'N' is the number of code-blocks in the tile. After all the code-blocks have been returned for the current tile calls to this method will return 'null'.

       <p>When changing the current tile (through 'setTile()' or 'nextTile()')
       this method will always return the first code-block, as if this method
       was never called before for the new current tile.</p><p>The data returned by this method is always a copy of the internal
       data of this object, if any, and it can be modified "in place" without
       any problems after being returned.</p>
getPPX(int, int, int)

Returns the width of a packet for the specified tile-component and resolution level.
getPPY(int, int, int)

Returns the height of a packet for the specified tile-component and resolution level.
precinctPartitionUsed(int, int)

Returns true if the precinct partition is used for the specified component and tile, returns false otherwise
