CSJ2K.j2k.entropy.decoder.StdEntropyDecoder.getInternCodeBlock C# (CSharp) Method

StdEntropyDecoder Class Documentation Show file Open project: cureos/csj2k

getInternCodeBlock() public method

Returns the specified code-block in the current tile for the specified component (as a reference or copy).

The returned code-block may be progressive, which is indicated by the 'progressive' variable of the returned 'DataBlk' object. If a code-block is progressive it means that in a later request to this method for the same code-block it is possible to retrieve data which is a better approximation, since meanwhile more data to decode for the code-block could have been received. If the code-block is not progressive then later calls to this method for the same code-block will return the exact same data values.

The data returned by this method can be the data in the internal buffer of this object, if any, and thus can not be modified by the caller. The 'offset' and 'scanw' of the returned data can be arbitrary. See the 'DataBlk' class.

The 'ulx' and 'uly' members of the returned 'DataBlk' object contain the coordinates of the top-left corner of the block, with respect to the tile, not the subband.
