This topic documents a feature of Visual Filters and Transitions, which is deprecated as of Windows Internet Explorer 9 and obsolete as of Internet Explorer 10.
Allocates an ARGB read pointer object.
virtual HRESULT CreateARGBPointer( CDXBaseSurface *pSurface, CDXBaseARGBPtr **ppPtr ) = 0;
Returns an HRESULT value that depends on the implementation of the interface.
Derived classes must override this virtual function.
A procedural surface object is required to define an ARGB sample access object that supports the IDXARGBReadPtr interface. The CDXBaseARGBPtr class can be used to simplify this.
