IMSVidVideoRenderer::get_MixerBitmapPositionRect

This topic applies to Windows XP or later.

The get_MixerBitmapPositionRect method retrieves the position of the static bitmap image, relative to the video window.

Syntax

  HRESULT get_MixerBitmapPositionRect(
  
  IMSVidRect**
  
  rDest
  
  );

Parameters

  pprDest

[out]  Address of a variable that receives an IMSVidRect interface pointer.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

If the static bitmap image is set, the VMR alpha-blends the bitmap onto the video image, using the position rectangle given in pprDest.

The returned IMSVidRect interface has an outstanding reference count. The caller must release the interface.

Requirements

  Header: Dshow.h.

  Library: Quartz.dll.
