CDrawImage::SlowRender

The SlowRender method draws the video image using the SetDIBitsToDevice or StretchDIBits functions.

Syntax

  void SlowRender(
    IMediaSample *pMediaSample
);

Parameters

pMediaSample

Pointer to the IMediaSample interface of the sample that contains the image.

Return Value

No return value.

Remarks

If CDrawImage::UsingImageAllocator returns FALSE, the CDrawImage::DrawImage method uses SlowRender to draw the video image. Otherwise, DrawImage uses the FastRender method.

Requirements

**  Header:** Declared in Winutil.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
