DXGI_GAMMA_CONTROL_CAPABILITIES structure

Controls the gamma capabilities of an adapter.

Syntax


typedef struct DXGI_GAMMA_CONTROL_CAPABILITIES {
  BOOL  ScaleAndOffsetSupported;
  float MaxConvertedValue;
  float MinConvertedValue;
  UINT  NumGammaControlPoints;
  float ControlPointPositions[1025];
} DXGI_GAMMA_CONTROL_CAPABILITIES;

Members

ScaleAndOffsetSupported: Type: BOOL; True if scaling and offset operations are supported during gamma correction; otherwise, false.
MaxConvertedValue: Type: float; A value describing the maximum range of the control-point positions.
MinConvertedValue: Type: float; A value describing the minimum range of the control-point positions.
NumGammaControlPoints: Type: UINT; A value describing the number of control points in the array.
ControlPointPositions: Type: float; An array of values describing control points; the maximum length of control points is 1025.
