CDrawImage.SetSourceRect method

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetSourceRect method sets the source rectangle.

Syntax

void SetSourceRect(
   RECT *pSourceRect
);

Parameters

pSourceRect

Pointer to a RECT structure that defines the new source 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::SetSourcePosition call.

Validate the rectangle given in pSourceRect before calling this method, to make sure it does not extend beyond the native video size.
