Signals an EC_REPAINT message to the filter graph.
Syntax
void SendRepaint(void);
Parameters
None.
Return Value
None.
Remarks
Use with care.
EC_REPAINT events are processed by the filter graph manager by setting the current position to the same position that the graph is 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.
