LoadImageFromStream method

Loads an image from a stream and returns a DXSurface.

Syntax

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

Parameters

  • 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.

Remarks

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

For more information about using the IStream interface, consult a Component Object Model (COM) reference.
