C# Class CSJ2K.j2k.wavelet.analysis.ForwardWT

This abstract class represents the forward wavelet transform functional block. The functional block may actually be comprised of several classes linked together, but a subclass of this abstract class is the one that is returned as the functional block that performs the forward wavelet transform.

This class assumes that data is transferred in code-blocks, as defined by the 'CBlkWTDataSrc' interface. The internal calculation of the wavelet transform may be done differently but a buffering class should convert to that type of transfer.
