Signals an EC_REPAINTmessage to the filter graph.
void SendRepaint(void);
Return Values
No return value.
Remarks
This should be used with some care. EC_REPAINTevents are processed by the filter graph manager by setting the current position to the same position that the graph is currently in. This has the effect of sending the same data through the graph again, which is an expensive operation. Video renderers are the main users of this event, because they sometimes need the same image sent again to refresh the display.
