LoadImageFromStream method

Loads an image from a stream and returns a DXSurface.

Syntax

HRESULT retVal = object.LoadImageFromStream(pStream, pDirectDraw, pDDSurfaceDesc, pFormatID, riid, ppDXSurface);

pStream [in]
Type: IStream

Pointer to the stream to use for the image load.
pDirectDraw [in]
Type: IUnknown

Pointer to the DirectDraw object to use.
pDDSurfaceDesc [in]
Type: const DDSURFACEDESC

Pointer to the DDSURFACEDESC structure that describes the underlying DirectDrawSurface object.
pFormatID [in]
Type: const GUID

Pointer to the overriding pixel format. If NULL, the format is determined by the source data.
riid [in]
Type: REFIID

Interface to return from the new surface.
ppDXSurface [out]
Type: void

Address of a pointer to the new interface.

All parameters except pStream are identical to the parameters of the IDXSurfaceFactory::LoadImage method.
