View the official Windows Driver Kit DDI referenceNo description available.
The D3DKMT_SETGAMMARAMP structure describes parameters for setting the gamma ramp.
hDevice [in]A handle to the device.
VidPnSourceId [in]The zero-based identification number of the video present source in a path of a video present network (VidPN) topology for the VidPN source.
Type [in]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).
pGammaRampRgb256x3x16 [in]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.
pGammaRampDXGI1 [in]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.
Size [in]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.
