D3DKMT_SETGAMMARAMP structure (d3dkmthk.h)

The D3DKMT_SETGAMMARAMP structure describes parameters for setting the gamma ramp.

Syntax

typedef struct _D3DKMT_SETGAMMARAMP {
  [in] D3DKMT_HANDLE                  hDevice;
  [in] D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
  [in] D3DDDI_GAMMARAMP_TYPE          Type;
  union {
    [in] D3DDDI_GAMMA_RAMP_RGB256x3x16 *pGammaRampRgb256x3x16;
    [in] D3DDDI_GAMMA_RAMP_DXGI_1      *pGammaRampDXGI1;
  };
  [in] UINT                           Size;
} D3DKMT_SETGAMMARAMP;

Members

[in] hDevice

A handle to the device.

[in] VidPnSourceId

The zero-based identification number of the video present source in a path of a video present network (VidPN) topology for the VidPN source.

[in] Type

A D3DDDI_GAMMARAMP_TYPE-typed value. This member can be one of the following: D3DDDI_GAMMARAMP_UNINITIALIZED (0), D3DDDI_GAMMARAMP_DEFAULT (1), D3DDDI_GAMMARAMP_RGB256x3x16 (2), or D3DDDI_GAMMARAMP_DXGI_1 (3).

[in] pGammaRampRgb256x3x16

A pointer to a D3DDDI_GAMMA_RAMP_RGB256x3x16 structure. The union that is contained in D3DKMT_SETGAMMARAMP holds a structure of this type if the Type member is D3DDDI_GAMMARAMP_RGB256x3x16.

[in] pGammaRampDXGI1

A pointer to a D3DDDI_GAMMA_RAMP_DXGI_1 structure. The union that is contained in D3DKMT_SETGAMMARAMP holds a structure of this type if the Type member is D3DDDI_GAMMARAMP_DXGI_1.

[in] Size

The size of the D3DDDI_GAMMA_RAMP_RGB256x3x16 or D3DDDI_GAMMA_RAMP_DXGI_1 structure that D3DDDI_GAMMA_RAMP_RGB256x3x16 or D3DDDI_GAMMA_RAMP_DXGI_1 points to.
