	Name	Description
	createInstance	Creates a ROIScaler object. The Quantizer is the source of data to scale. The ROI Scaler creates a ROIMaskGenerator depending on what ROI information is in the ParameterList. If only rectangular ROI are used, the fast mask generator for rectangular ROI can be used.
	getAnSubbandTree	Returns a reference to the subband tree structure representing the subband decomposition for the specified tile-component.
	getCompImgHeight	Returns the height in pixels of the specified component in the overall image. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getCompImgWidth	Returns the width in pixels of the specified component in the overall image. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getCompSubsX	Returns the component subsampling factor in the horizontal direction, for the specified component. This is, approximately, the ratio of dimensions between the reference grid and the component itself, see the 'ImgData' interface desription for details. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getCompSubsY	Returns the component subsampling factor in the vertical direction, for the specified component. This is, approximately, the ratio of dimensions between the reference grid and the component itself, see the 'ImgData' interface desription for details. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getCompULX	Returns the horizontal coordinate of the upper-left corner of the specified component in the current tile. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getCompULY	Returns the vertical coordinate of the upper-left corner of the specified component in the current tile. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getNextCodeBlock	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. The function calls on a ROIMaskGenerator to get the mask for scaling the coefficients in the current block. The data returned by this method is a copy of the orignal data. Therfore it can be modified "in place" without any problems after being returned. The 'offset' of the returned data is 0, and the 'scanw' is the same as the code-block width. See the 'CBlkWTData' class.
	getNextInternCodeBlock	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. The function calls on a ROIMaskGenerator to get the mask for scaling the coefficients in the current block.
	getNomRangeBits	(Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getNumTiles	Overloaded. Returns the number of tiles in the horizontal and vertical directions. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getTile	Returns the indexes of the current tile. These are the horizontal and vertical indexes of the current tile. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getTileCompHeight	Returns the height in pixels of the specified tile-component. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	getTileCompWidth	Returns the width in pixels of the specified tile-component tile. This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter)
	isReversible	Since ROI scaling is always a reversible operation, it calls isReversible() method of it source (the quantizer module).
	nextTile	Overridden. Advances to the next tile, in standard scan-line order (by rows then columns). An NoNextElementException is thrown if the current tile is the last one (i.e. there is no next tile).
	setTile	Overridden. Changes the current tile, given the new indexes. An IllegalArgumentException is thrown if the indexes do not correspond to a valid tile.
	useRoi	This function returns the flag indicating if any ROI functionality used
