CDXBaseSurface::CreateARGBPointer Method

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.

Syntax


virtual HRESULT CreateARGBPointer(
    CDXBaseSurface *pSurface,
    CDXBaseARGBPtr **ppPtr
) = 0;

Parameters

pSurface
[in] Pointer to the CDXBaseSurface object.
ppPtr
[out] Address of a pointer to the newly created CDXBaseARGBPtr class object.

Return Value

Returns an HRESULT value that depends on the implementation of the interface.

Remarks

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.
