IDecimateVideoImage interface

The IDecimateVideoImage interface specifies decimation on a decoder filter. The term decimation refers to scaling the video output down to a size smaller than the native size of the video.

Applications must not call methods on this interface. The Overlay Mixer filter uses this interface to decimate video at the video decoder.
