WM_CAP_PAL_OPEN message
The WM_CAP_PAL_OPEN message loads a new palette from a palette file and passes it to a capture driver. Palette files typically use the filename extension .PAL. A capture driver uses a palette when required by the specified digitized image format. You can send this message explicitly or by using the capPaletteOpen macro.
