DKGK_GAMMA_DATA_CAP structure

Description

Gamma data caps.

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.
