Remarks
This member function implements the IBasicVideo::get_DestinationLeft method.
An application can change the source and destination rectangles for the video through the IBasicVideo interface. The source rectangle affects which section of the native video source will appear on the display; the destination rectangle affects where the video will appear when played. The destination rectangle is relative to the client area of the window in which it is playing. The upper-left corner of the window is coordinate (0,0).
Requirements
** Header:** Declared in Ctlutil.h; include Streams.h.
