);

Parameters

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::GetCurrentImagewhen a null pVideoImageparameter is passed to that member function.

As a result, this member function constructs and returns a VIDEOINFOHEADERstructure, using the information in pBufferSizeand pSourceRect.
