colour.models.log_decoding_ACESproxy#

colour.models.log_decoding_ACESproxy(ACESproxy: Domain1, bit_depth: Literal[10, 12] = 10, in_int: bool = False, constants: dict | None = None) → Range1[source]#

Apply the ACESproxy log decoding inverse opto-electronic transfer function (OETF).

Parameters:

ACESproxy (Domain1) – ACESproxy non-linear encoded value.
bit_depth (Literal[10, 12]) – ACESproxy bit-depth.
in_int (bool) – Whether to treat the input value as integer code value or floating point equivalent of a code value at specified bit-depth.
constants (dict | None) – ACESproxy constants.

Returns:

Linear AP1 colourspace value.

Return type:

numpy.ndarray

Notes

Domain	Scale - Reference	Scale - 1
`ACESproxy`	1	1

Range	Scale - Reference	Scale - 1
`lin_AP1`	1	1

This definition has an input int switch, thus the domain-range scale information is only specified for the floating point mode.
