Remarks

An application can query the colors required by the video with this method. An application can pass in a null pPalette parameter, and the pRetrieved parameter is filled in with the number of colors in use. The pPalette parameter is a pointer to an array of PALETTEENTRY structures. With the StartIndex and Entries parameters, an application can request any contiguous section of the palette in a single method. The interface was modeled on the Win32 GetSystemPaletteEntries function.
