colour.models.log_encoding_ACEScct(lin_AP1: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1], constants: Structure | None = None) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 1][source]#

Apply the ACEScct log encoding opto-electronic transfer function (OETF).

Parameters:

lin_AP1 (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – Linear AP1 colourspace value.
constants (Structure | None) – ACEScct constants.

Returns:

ACEScct non-linear encoded value.

Return type:

numpy.ndarray
