ISurfaceManager::AllocSurface method

The AllocSurface method allocates a new ISurface interface for the application to use. ISurface wraps an IDirect3DSurface9 interface. However, the recommended way to allocate a surface is described in the IMediaTransform::Process method documentation.

Syntax

HRESULT AllocSurface(
  [in]  FORMAT_TYPE type,
  [out] ISurface    **ppBuffer
);

Parameters

type [in]

A FORMAT_TYPE value specifying the type of surface to create.

ppBuffer [out]

Pointer to an ISurface interface pointer wrapping a Direct3D video surface. The caller must release this interface when done with it.

Return value

The method returns an HRESULT of S_OK for success, or a standard COM error code for failure.

Remarks

To allocate a surface of a specific size, call AllocSurfaceSize.
