CBaseControlVideo::CopyImage (Windows Embedded CE 6.0)
1/6/2010
Creates a memory copy of an image.
Syntax
HRESULT CopyImage(
IMediaSample* pMediaSample,
VIDEOINFOHEADER* pVideoInfo,
LONG* pBufferSize,
BYTE* pVideoImage,
RECT* pSourceRect
);
Parameters
- pMediaSample
Sample containing the video image.
- pVideoInfo
Format representing the video image.
- pBufferSize
Size of the output buffer.
- pVideoImage
Pointer to the output buffer.
- pSourceRect
Source video rectangle.
Return Value
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.
Remarks
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).
