colour.models.log_decoding_ACESproxy¶
- colour.models.log_decoding_ACESproxy(ACESproxy: Union[FloatingOrArrayLike, IntegerOrArrayLike], bit_depth: Literal[10, 12] = 10, in_int: Boolean = False, constants: Dict = CONSTANTS_ACES_PROXY) FloatingOrNDArray [source]¶
Define the ACESproxy colourspace log decoding curve / electro-optical transfer function.
- Parameters
ACESproxy (Union[FloatingOrArrayLike, IntegerOrArrayLike]) – ACESproxy non-linear value.
bit_depth (Literal[(10, 12)]) – ACESproxy bit depth.
in_int (Boolean) – Whether to treat the input value as integer code value or float equivalent of a code value at a given bit depth.
constants (Dict) – ACESproxy constants.
- Returns
lin_AP1 value.
- Return type
