IDirectDrawGammaControl
This interface allows you to get and set gamma controls:
| PPC | SP | ||
|---|---|---|---|
| Gamma controls | X | X | GetGammaRamp |
| X | X | SetGammaRamp |
The IDirectDrawGammaControl interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| PPC | SP | ||
|---|---|---|---|
| IUnknown | X | X | AddRef |
| X | X | QueryInterface | |
| X | X | Release |
You can use the LPDIRECTDRAWGAMMACONTROL data type to declare a variable that contains a pointer to an IDirectDrawGammaControl interface.
The Ddraw.h header file declares these data types with the following code.
typedef struct IDirectDrawGammaControl FAR *LPDIRECTDRAWGAMMACONTROL;
