ImgHeight | Returns the overall height of the image in pixels. This is the image's height without accounting for any component subsampling or tiling.
This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
ImgULX | Returns the horizontal coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid.
This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
ImgULY | Returns the vertical coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid.
This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
ImgWidth | Returns the overall width of the image in pixels. This is the image's width without accounting for any component subsampling or tiling.
This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
NomTileHeight | Returns the nominal tiles height (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
NomTileWidth | Returns the nominal tiles width (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
NumComps | Returns the number of components in the image.
This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
ParameterInfo | Returns the parameters that are used in this class and implementing classes. It returns a 2D String array. Each of the 1D arrays is for a different option, and they have 4 elements. The first element is the option name, the second one is the synopsis, the third one is a long description of what the parameter is and the fourth is its default value. The synopsis or description may be 'null', in which case it is assumed that there is no synopsis or description of the option, respectively. Null may be returned if no options are supported. | |
Reversible | Returns true if this transform is reversible in current tile. Reversible component transformations are those which operation can be completely reversed without any loss of information (not even due to rounding). | |
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. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
TileIdx | Returns the index of the current tile, relative to a standard scan-line order.
This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
TilePartULX | Returns the horizontal tile partition offset in the reference grid (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
TilePartULY | Returns the vertical tile offset in the reference grid (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
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. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) |

This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
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.
This default implementation returns the value of the source. (Inherited from CSJ2K.j2k.image.ImgDataAdapter) | |
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.
