This functionality forms the basis for dynamically modifying parameters to a decompressor. It also allows for codecs to act as special effects components, providing filtering and transition type effects. A client can attach an arbitrary number of additional inputs to the codec. It is up to the particular codec to determine whether to use each input and how to interpret the input. For example, an 8-bit gray image could be interpreted as a blend mask or as a replacement for one of the RGB data planes.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD
