InvCompTransf ( BlkImgDataSrc imgSrc, |
Constructs a new ForwCompTransf object that operates on the specified source of image data.
|
|
| ToString ( ) : System.String |
Returns a string with a descriptive text of which inverse component transformation is used. This can be either "Inverse RCT" or "Inverse ICT" or "No component transformation" depending on the current tile.
|
|
| calcMixedBitDepths ( int utdepth, int ttype, int tdepth ) : int[] |
Calculates the bitdepths of the transformed components, given the bitdepth of the un-transformed components and the component tranformation type.
|
|
| close ( ) : void |
Closes the underlying file or network connection from where the image data is being read.
|
|
| getCompData ( CSJ2K.j2k.image.DataBlk blk, int c ) : CSJ2K.j2k.image.DataBlk |
Apply inverse component transformation associated with the current tile. If no component transformation has been requested by the user, data are not modified. This method calls the getInternCompData() method, but respects the definitions of the getCompData() method defined in the BlkImgDataSrc interface.
|
|
| getFixedPoint ( int c ) : int |
Returns the position of the fixed point in the specified component. 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. This default implementation assumes that the number of fractional bits is not modified by the component mixer.
|
|
| getInternCompData ( CSJ2K.j2k.image.DataBlk blk, int c ) : CSJ2K.j2k.image.DataBlk |
Apply the inverse component transformation associated with the current tile. If no component transformation has been requested by the user, data are not modified. Else, appropriate method is called (invRCT or invICT).
|
|
| getNomRangeBits ( int c ) : int |
Returns the number of bits, referred to as the "range bits", corresponding to the nominal range of the data in the specified component. If this number is b then for unsigned data the nominal range is between 0 and 2^b-1, and for signed data it is between -2^(b-1) and 2^(b-1)-1.
|
|
| isOrigSigned ( int c ) : bool |
Returns true if the data read was originally signed in the specified component, false if not.
|
|
| nextTile ( ) : void |
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). This default implementation just advances to the next tile in the source and re-initializes properly component transformation variables.
|
|
| setTile ( int x, int y ) : void |
Changes the current tile, given the new indexes. An IllegalArgumentException is thrown if the indexes do not correspond to a valid tile. This default implementation changes the tile in the source and re-initializes properly component transformation variables..

| invICT ( CSJ2K.j2k.image.DataBlk blk, int c ) : CSJ2K.j2k.image.DataBlk |
Apply inverse irreversible component transformation to obtain requested component from specified block of data. Whatever the type of requested DataBlk, it always returns a DataBlkFloat.
|
|
| invRCT ( CSJ2K.j2k.image.DataBlk blk, int c ) : CSJ2K.j2k.image.DataBlk |
Apply inverse component transformation to obtain requested component from specified block of data. Whatever the type of requested DataBlk, it always returns a DataBlkInt.
