Creates a memory copy of an image.
HRESULT CopyImage( IMediaSample *pMediaSample, VIDEOINFOHEADER *pVideoInfo, LONG *pBufferSize, BYTE *pVideoImage, RECT *pSourceRect );
Pointer to the sample containing the video image.
Pointer to the format representing the video image.
Pointer to the size of the output buffer.
Pointer to the output buffer.
Pointer to the source video rectangle.
If the pVideoImage parameter is NULL, the pBufferSize parameter is filled in with the number of bytes the output buffer requires to store the image. If the buffer passed in is too small or the member function fails to allocate sufficient memory, the member function returns E_OUTOFMEMORY.
The member function retrieves the image from the sample and copies it into the output buffer. The section of video copied into the output buffer reflects the source rectangle that is set through the IBasicVideo interface (although it does not reflect the destination rectangle).
