 | getCodeBlock | Returns the specified coded code-block, for the specified component, in the current tile. The first layer to return is indicated by 'fl'. The number of layers that is returned depends on 'nl' and the amount of data available.
The argument 'fl' is to be used by subsequent calls to this method for the same code-block. In this way supplamental data can be retrieved at a later time. The fact that data from more than one layer can be returned means that several packets from the same code-block, of the same component, and the same tile, have been concatenated.
The returned compressed code-block can have its progressive attribute set. If this attribute is set it means that more data can be obtained by subsequent calls to this method (subject to transmission delays, etc). If the progressive attribute is not set it means that the returned data is all the data that can be obtained for the specified subblock.
The compressed code-block is uniquely specified by the current tile, the component (identified by 'c'), the subband (indentified by 'sb') and the code-bock vertical and horizontal indexes 'm' and 'n'.
The 'ulx' and 'uly' members of the returned 'DecLyrdCBlk' 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) |
| 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) |
