 | ImgHeight | Returns the overall height of the image in pixels. This is the image's height without accounting for any component subsampling or tiling. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| ImgResLevel | Sets the image reconstruction resolution level. A value of 0 means reconstruction of an image with the lowest resolution (dimension) available.
Note: Image resolution level indexes may differ from tile-component resolution index. They are indeed indexed starting from the lowest number of decomposition levels of each component of each tile. Example: For an image (1 tile) with 2 components (component 0 having 2 decomposition levels and component 1 having 3 decomposition levels), the first (tile-) component has 3 resolution levels and the second one has 4 resolution levels, whereas the image has only 3 resolution levels available.

| 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.
This default implementation returns the value of the source at the current reconstruction resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| TileIdx | Returns the index of the current tile, relative to a standard scan-line order.

| TilePartULX | Returns the horizontal tile partition offset in the reference grid (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| TilePartULY | Returns the vertical tile partition offset in the reference grid (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| 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.
This default implementation returns the value of the source at the current reconstruction resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| Name | Description | |

 | getCompData | Overridden. Returns a block of image data containing the specifed rectangular area, in the specified component, as a copy (see below). The rectangular area is specified by the coordinates and dimensions of the 'blk' object.
The area to return is specified by the 'ulx', 'uly', 'w' and 'h' members of the 'blk' argument. These members are not modified by this method. 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. The 'offset' of the returned data is 0, and the 'scanw' is the same as the block's width. See the 'DataBlk' class. If the data array in 'blk' is null, then a new one is created. If the data array is not null then it must be big enough to contain the requested area. The returned data always has its 'progressive' attribute unset (i.e false) |
| getCompImgHeight | Returns the height in pixels of the specified component in the overall image.
This default implementation returns the value of the source at the current reconstruction resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| getCompImgWidth | Returns the width in pixels of the specified component in the overall image. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| 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.wavelet.synthesis.InvWTAdapter) |
| 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.wavelet.synthesis.InvWTAdapter) |
| getCompULX | Returns the horizontal coordinate of the upper-left corner of the specified component in the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| getCompULY | Returns the vertical coordinate of the upper-left corner of the specified component in the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| getFixedPoint | Overridden. Returns the position of the fixed point in the specified component. This is the position of the least significant integral (i.e. non-fractional) bit, which is equivalent to the number of fractional bits. For instance, for fixed-point values with 2 fractional bits, 2 is returned. For floating-point data this value does not apply and 0 should be returned. Position 0 is the position of the least significant bit in the data.
This default implementation assumes that the wavelet transform does not modify the fixed point. If that were the case this method should be overriden. |
| getImplementationType | Overridden. Returns the implementation type of this wavelet transform, WT_IMPL_FULL (full-page based transform). All components return the same. |
| getInternCompData | Overridden. Returns a block of image data containing the specifed rectangular area, in the specified component, as a reference to the internal buffer (see below). The rectangular area is specified by the coordinates and dimensions of the 'blk' object.
The area to return is specified by the 'ulx', 'uly', 'w' and 'h' members of the 'blk' argument. These members are not modified by this method. 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 returned data has its 'progressive' attribute unset (i.e. false). |
| getNomRangeBits | Overridden. |
| 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.wavelet.synthesis.InvWTAdapter) |
| getSynSubbandTree | Returns the specified synthesis subband tree (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| getTile | Returns the indixes 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.wavelet.synthesis.InvWTAdapter) |
| getTileCompHeight | Returns the height in pixels of the specified tile-component.
This default implementation returns the value of the source at the current reconstruction resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| getTileCompWidth | Returns the width in pixels of the specified tile-component (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTAdapter) |
| isReversible | Overridden. Returns the reversibility of the wavelet transform for the specified component, in the current tile. A wavelet transform is reversible when it is suitable for lossless and lossy-to-lossless compression. |
| 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. |
