This function gets a datablk from the entropy coder. The sample sin the block, which consists of the quantized coefficients from the quantizer, are scaled by the values given for any ROIs specified.
<p>The function calls on a ROIMaskGenerator to get the mask for scaling
the coefficients in the current block.</p>
public virtual CBlkWTData getNextInternCodeBlock(int c, CBlkWTData cblk)
Type | Name | Description |
---|---|---|
int | c | The component for which to return the next code-block. |
CBlkWTData | cblk | If non-null this object will be used to return the new code-block. If null a new one will be allocated and returned. If the "data" array of the object is non-null it will be reused, if possible, to return the data. |
Type | Description |
---|---|
CBlkWTData | The next code-block in the current tile for component 'n', or null if all code-blocks for the current tile have been returned. |
