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.
