Retrieves the interface to the selected color lookup table.
HRESULT GetLookup( IDXLookupTable **ppLookupTable );
- [out] Address of a pointer that is initialized to the current lookup table object of the Surface Modifier.
Returns an HRESULT value that depends on the implementation of the interface.
If there is currently no lookup table operator, this function returns S_OK, but ppLookupTable is set to NULL. Otherwise, the returned pointer points to an IDXLookupTable interface. When the method is implemented, it automatically calls AddRef on the interface. The client is responsible for calling Release on the interface when it is no longer needed.
The lookup table is applied to the foreground surface only.
