Comments

This function will capture a single device independent bitmap.

If the method succeeds, the caller must free the returned HDIB by calling the GlobalFree function.

Note: The frame data is retrieved from the underlying graph after the processing

 filters. If the capture needs to occur before the processing is completed

 use the LeadVideoCallBackFilter and place it first in the collection of

 processing filters.
