Public Properties

	Name	Description
	CbULX	Returns the horizontal offset of the code-block partition. Allowable values are 0 and 1, nothing else. (Inherited from CSJ2K.j2k.wavelet.analysis.ForwWTDataProps)

	ImgULX	Returns the horizontal coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid. (Inherited from CSJ2K.j2k.image.ImgData)
	ImgULY	Returns the vertical coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid. (Inherited from CSJ2K.j2k.image.ImgData)
	ImgWidth	Returns the overall width of the image in pixels. This is the image's width without accounting for any component subsampling or tiling. (Inherited from CSJ2K.j2k.image.ImgData)
	NomTileHeight	Returns the nominal tiles height (Inherited from CSJ2K.j2k.image.ImgData)
	NomTileWidth	Returns the nominal tiles width (Inherited from CSJ2K.j2k.image.ImgData)
	NumComps	Returns the number of components in the image. (Inherited from CSJ2K.j2k.image.ImgData)
	TileHeight	Returns the overall height of the current tile in pixels. This is the tile's height without accounting for any component subsampling. This is also referred as the reference grid height in the current tile. (Inherited from CSJ2K.j2k.image.ImgData)
	TileIdx	Returns the index of the current tile, relative to a standard scan-line order. (Inherited from CSJ2K.j2k.image.ImgData)
	TilePartULX	Returns the horizontal tile partition offset in the reference grid (Inherited from CSJ2K.j2k.image.ImgData)
	TilePartULY	Returns the vertical tile partition offset in the reference grid (Inherited from CSJ2K.j2k.image.ImgData)
	TileWidth	Returns the overall width of the current tile in pixels. This is the tile's width without accounting for any component subsampling. This is also referred as the reference grid width in the current tile. (Inherited from CSJ2K.j2k.image.ImgData)

Public Methods

	Name	Description
	getAnSubbandTree	Returns a reference to the root of subband tree structure representing the subband decomposition for the specified tile-component. (Inherited from CSJ2K.j2k.wavelet.analysis.ForwWTDataProps)
	getCompImgHeight	Returns the height in pixels of the specified component in the overall image. (Inherited from CSJ2K.j2k.image.ImgData)
	getCompImgWidth	Returns the width in pixels of the specified component in the overall image. (Inherited from CSJ2K.j2k.image.ImgData)
	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. (Inherited from CSJ2K.j2k.image.ImgData)
	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. (Inherited from CSJ2K.j2k.image.ImgData)
	getCompULX	Returns the horizontal coordinate of the upper-left corner of the specified component in the current tile. (Inherited from CSJ2K.j2k.image.ImgData)
	getCompULY	Returns the vertical coordinate of the upper-left corner of the specified component in the current tile. (Inherited from CSJ2K.j2k.image.ImgData)
	getDecomp	Returns the wavelet tree decomposition. Only WT_DECOMP_DYADIC is supported by JPEG 2000 part I.
	getDecompLevels	Returns the number of decomposition levels that are applied to obtain the LL band, in the specified tile-component. A value of 0 means that no wavelet transform is applied.
	getHorAnWaveletFilters	Returns the horizontal analysis wavelet filters used in each level, for the specified tile-component. The first element in the array is the filter used to obtain the lowest resolution (resolution level 0) subbands (i.e. lowest frequency LL subband), the second element is the one used to generate the resolution level 1 subbands, and so on. If there are less elements in the array than the number of resolution levels, then the last one is assumed to repeat itself. The returned filters are applicable only to the specified component and in the current tile. The resolution level of a subband is the resolution level to which a subband contributes, which is different from its decomposition level.
	getImplementationType	Returns the implementation type of this wavelet transform (WT_IMPL_LINE or WT_IMPL_FRAME) for the specified component, in the current tile. (Inherited from CSJ2K.j2k.wavelet.WaveletTransform)
	getNomRangeBits	(Inherited from CSJ2K.j2k.image.ImgData)
	getNumTiles	Returns the number of tiles in the horizontal and vertical directions. (Inherited from CSJ2K.j2k.image.ImgData)
	getTile	Returns the indixes of the current tile. These are the horizontal and vertical indexes of the current tile. (Inherited from CSJ2K.j2k.image.ImgData)
	getTileCompHeight	Returns the height in pixels of the specified tile-component. (Inherited from CSJ2K.j2k.image.ImgData)
	getTileCompWidth	Returns the width in pixels of the specified tile-component (Inherited from CSJ2K.j2k.image.ImgData)
	getVertAnWaveletFilters	Returns the vertical analysis wavelet filters used in each level, for the specified tile-component. The first element in the array is the filter used to obtain the lowest resolution (resolution level 0) subbands (i.e. lowest frequency LL subband), the second element is the one used to generate the resolution level 1 subbands, and so on. If there are less elements in the array than the number of resolution levels, then the last one is assumed to repeat itself. The returned filters are applicable only to the specified component and in the current tile. The resolution level of a subband is the resolution level to which a subband contributes, which is different from its decomposition level.
	isReversible	Returns the reversibility of the wavelet transform for the specified component and tile. A wavelet transform is reversible when it is suitable for lossless and lossy-to-lossless compression. (Inherited from CSJ2K.j2k.wavelet.WaveletTransform)
	nextTile	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). (Inherited from CSJ2K.j2k.image.ImgData)
	setTile	Changes the current tile, given the new indices. An IllegalArgumentException is thrown if the coordinates do not correspond to a valid tile. (Inherited from CSJ2K.j2k.image.ImgData)
