| Name | Description |
| getCodeBlock | Returns the specified code-block in the current tile for the specified component, as a copy (see below).
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 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 code-block width. 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. |
| getCompImgHeight | Returns the height in pixels of the specified component in the overall image, for the given resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getCompImgWidth | Returns the width in pixels of the specified component in the overall image, for the given resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| 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.MultiResImgData) |
| 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.MultiResImgData) |
| getImgHeight | Returns the overall height of the image in pixels, for the given resolution level. This is the image's height without accounting for any component subsampling or tiling. The resolution level is indexed from the lowest number of resolution levels of all components of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getImgULX | Returns the horizontal coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid at the specified resolution level. The resolution level is indexed from the lowest number of resolution levels of all components of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getImgULY | Returns the vertical coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid at the specified resolution level. The resolution level is indexed from the lowest number of resolution levels of all components of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getImgWidth | Returns the overall width of the image in pixels, for the given resolution level. This is the image's width without accounting for any component subsampling or tiling. The resolution level is indexed from the lowest number of resolution levels of all components of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getInternCodeBlock | 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. |
| getNumTiles | Returns the number of tiles in the horizontal and vertical directions. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getResULX | Returns the horizontal coordinate of the upper-left corner of the specified resolution in the given component of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getResULY | Returns the vertical coordinate of the upper-left corner of the specified resolution in the given component of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getSynSubbandTree | Returns the subband tree, for the specified tile-component. This method returns the root element of the subband tree structure, see 'Subband' and 'SubbandSyn'. The tree comprises all the available resolution levels. (Inherited from CSJ2K.j2k.wavelet.synthesis.InvWTData) |
| getTile | Returns the indexes of the current tile. These are the horizontal and vertical indexes of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getTileCompHeight | Returns the height in pixels of the specified tile-component for the given resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getTileCompWidth | Returns the width in pixels of the specified tile-component for the given resolution level. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getTileHeight | Returns the overall height of the current tile in pixels, for the given resolution level. This is the tile's height without accounting for any component subsampling. The resolution level is indexed from the lowest number of resolution levels of all components of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| getTileWidth | Returns the overall width of the current tile in pixels for the given resolution level. This is the tile's width without accounting for any component subsampling. The resolution level is indexed from the lowest number of resolution levels of all components of the current tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
| 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.wavelet.synthesis.MultiResImgData) |
| setTile | Changes the current tile, given the new indexes. An IllegalArgumentException is thrown if the indexes do not correspond to a valid tile. (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgData) |
