ISurfaceManager::AllocSurfaceSize method
The AllocSurfaceSize method allocates a new ISurface of a specific size. ISurface wraps an IDirect3DSurface9 interface. However, the recommended way to allocate a surface is described in the IMediaTransform::Process documentation.
Syntax
HRESULT AllocSurfaceSize(
[in] FORMAT_TYPE type,
VIDEO_SIZE *pSize,
[out] ISurface **ppBuffer
);
Parameters
-
type [in]
-
A FORMAT_TYPE value that specifies the type of surface to create.
-
pSize
-
A VIDEO_SIZE structure that specifies the size of the surface to allocate.
-
ppBuffer [out]
-
Pointer to an ISurface interface pointer that wraps 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
If you do not know the exact size of the surface to allocate, use AllocSurface.
