Public Properties
Public Methods
| Name | Description |
| getCompData | |
| 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) |
| getFixedPoint | Returns the position of the fixed point in the specified component, or equivalently the number of fractional bits. 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. |
| getInternCompData | |
| 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) |
| 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) |
