CDrawImage.SlowRender 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 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
This method does not return a value.
Remarks
If CDrawImage::UsingImageAllocator returns FALSE, the CDrawImage::DrawImage method uses SlowRender to draw the video image. Otherwise, DrawImage uses the FastRender method.
