Interface InvWT

All Superinterfaces:

ImgData, WaveletTransform

All Known Implementing Classes:

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 envisageable for different transforms.

Method Detail

setImgResLevel

public 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.

Returns:

The vertical coordinate of the image origin in the canvas system, on the reference grid.
