Syntax

HRESULT GetImageSize(
  VIDEOINFOHEADER* pVideoInfo,
  long* pBufferSize,
  RECT* pSourceRect
);

Parameters

• pVideoInfo
  Pointer to a VIDEOINFOHEADER structure to be filled in.

• pBufferSize
  Size of the video buffer.

• pSourceRect
  Rectangle dimensions of the source video.

Return Value

Remarks

This member function is a helper function used for creating memory image renderings of DIB images.

It is called from the base class implementation of CBaseControlVideo::GetCurrentImage when a null pVideoImage parameter is passed to that member function.

As a result, this member function constructs and returns a VIDEOINFOHEADER structure, using the information in pBufferSize and pSourceRect.
