CDrawImage.SetTargetRect method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The SetTargetRect method sets the target rectangle.
Syntax
void SetTargetRect(
RECT *pTargetRect
);
Parameters
-
pTargetRect

Pointer to a RECT structure that defines the new target rectangle.
Return value
This method does not return a value.
Remarks
The owning filter should call this method if the source rectangle changes; for example, in response to an IBasicVideo::SetDestinationPosition call.
Before calling this method, validate the rectangle given in pTargetRect, relative to the video window.
