Interface InvWT
- All Superinterfaces:
- ImgData, WaveletTransform
- All Known Implementing Classes:
- InverseWT, InvWTAdapter
public interface InvWT
- extends WaveletTransform
This interface extends the WaveletTransform with the
specifics of inverse wavelet transforms. Classes that implement inverse
wavelet transfoms should implement this interface.
This class does not define the methods to transfer data, just the
specifics to inverse wavelet transform. Different data transfer methods are
evisageable for different transforms.

setImgResLevel
void setImgResLevel(int rl)
- Sets the image reconstruction resolution level. A value of 0
means reconstruction of an image with the lowest resolution
(dimension) available.
Note: Image resolution level indexes may differ from
tile-component resolution index. They are indeed indexed
starting from the lowest number of decomposition levels of each
component of each tile.
Example: For an image (1 tile) with 2 components (component
0 having 2 decomposition levels and component 1 having 3
decomposition levels), the first (tile-) component has 3
resolution levels and the second one has 4 resolution levels,
whereas the image has only 3 resolution levels available.
- Parameters:
rl
- The image resolution level.
