IDirectDrawPalette Interface Method Groups
Applications use the methods of the IDirectDrawPalette interface to create DirectDrawPalette objects and work with system-level variables. The methods can be organized into the following groups:
Allocating memory Initialize
IUnknown AddRef
Palette capabilities GetCaps
Palette entries GetEntries
All COM interfaces inherit the IUnknown interface methods, which are listed in the "IUnknown" group above. These three methods allow additional interfaces to be added to the DirectDrawPalette object without affecting the functionality of the original interface.
