CBaseControlVideo::CopyImage (Windows CE 5.0)
Creates a memory copy of an image.
HRESULTCopyImage(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 Values
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).
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
