Public Properties
| | Name | Description |
|---|
 | CbULX | Returns the horizontal offset of the code-block partition. Allowable values are 0 and 1, nothing else. |
| CbULY | Returns the vertical offset of the code-block partition. Allowable values are 0 and 1, nothing else. |
| 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.image.ImgData) |
| 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) |
TopPublic Methods
| | Name | Description |
|---|
 | getAnSubbandTree | Returns a reference to the root of 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. (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) |
| 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) |
| isReversible | Returns the reversibility of the given tile-component. Data is reversible when it is suitable for lossless and lossy-to-lossless compression. |
| 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) |
