Gamma data caps.

Syntax

typedef struct _DKGK_GAMMA_DATA_CAP {
  DXGK_GAMMA_DATA_TYPE DataType;
  union {
    struct {
      UINT BitCountOfInteger : 6;
      UINT BitCountOfFraction : 6;
    };
    struct {
      UINT BitCountOfExponent : 6;
      UINT BitCountOfMantissa : 6;
    };
    UINT Value;
  };
  float                NumericRangeMin;
  float                NumericRangeMax;
} DKGK_GAMMA_DATA_CAP;

Members

DataType

A DXGK_GAMMA_DATA_TYPE enumeration value.

BitCountOfInteger

Bit count of integer if DataType is fixed-point(DXGK_GAMMA_DATA_TYPE_FIXED_POINT).

BitCountOfFraction

Bit count of fraction if DataType is fixed-point(DXGK_GAMMA_DATA_TYPE_FIXED_POINT).

BitCountOfExponent

Bit count of exponent if the DataType is float(DXGK_GAMMA_DATA_TYPE_FLOAT).

BitCountOfMantissa

Bit count of mantissa if the DataType is float(DXGK_GAMMA_DATA_TYPE_FLOAT).

Value

NumericRangeMin

Minimum number of gamma data.

NumericRangeMax

Maximum number of gamma data.
