Remarks
An application can query the colors required by the video with this method. An application can pass in a null pPaletteparameter, and the pRetrievedparameter is filled in with the number of colors in use.

With the StartIndexand Entriesparameters, an application can request any contiguous section of the palette in a single method. The interface was modeled on the Win32 GetSystemPaletteEntriesfunction.
