This interface defines how a forward or inverse wavelet transform should present itself. As specified in the ImgData interface, from which this class inherits, all operations are confined to the current tile, and all coordinates are relative to it.

       <p>The definition of the methods in this interface allows for different
       types of implementation, reversibility and levels of decompositions for
       each component and each tile. An implementation of this interface does not
       need to support all this flexibility (e.g., it may provide the same
       implementation type and decomposition levels for all tiles and
       components).</p>
