DXGK_GAMMARAMPCAPS structure (d3dkmddi.h)
The DXGK_GAMMARAMPCAPS structure identifies gamma-ramp capabilities of the display miniport driver that the driver provides through a call to its DxgkDdiQueryAdapterInfo function.
Syntax
typedef struct _DXGK_GAMMARAMPCAPS {
union {
struct {
UINT Gamma_Rgb256x3x16 : 1;
UINT Reserved : 31;
};
UINT Value;
};
} DXGK_GAMMARAMPCAPS;
Members
Gamma_Rgb256x3x16
A UINT value that specifies whether gamma ramp data is stored as 256 16-bit RGB values. Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).
Reserved
This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 31 bits (0xFFFFFFFE) of the 32-bit Value member to zeros.
Value
A member in the union that DXGK_GAMMARAMPCAPS contains that can hold a 32-bit value that identifies gamma-ramp capabilities.
