colour.ootf

colour.ootf(value: _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | bool | int | float | complex | str | bytes | _NestedSequence[bool | int | float | complex | str | bytes], function: Literal['ITU-R BT.2100 HLG', 'ITU-R BT.2100 PQ'] | str = 'ITU-R BT.2100 PQ', **kwargs: Any) → ndarray[Any, dtype[float16 | float32 | float64]]

Map relative scene linear light to display linear light using given opto-optical transfer function (OOTF / OOCF).

Parameters:

• value (_SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | bool | int | float | complex | str | bytes | _NestedSequence[bool | int | float | complex | str | bytes]) – Value.

• function (Literal['ITU-R BT.2100 HLG', 'ITU-R BT.2100 PQ'] | str) – Opto-optical transfer function (OOTF / OOCF).

• kwargs (Any) – {colour.models.ootf_BT2100_HLG(), colour.models.ootf_BT2100_PQ()}, See the documentation of the previously listed definitions.

Returns:

Luminance of a displayed linear component.

Return type:

numpy.ndarray
