colour.models.cctf_decoding_RIMMRGB(X_p: ArrayLike, bit_depth: int = 8, in_int: bool = False, E_clip: float = 2.0) → NDArrayFloat[source]#

Define the RIMM RGB decoding colour component transfer function (Encoding CCTF).

Parameters:

X_p (ArrayLike) – Non-linear data \(X'_{RIMM}\).
bit_depth (int) – Bit-depth used for conversion.
in_int (bool) – Whether to treat the input value as int code value or float equivalent of a code value at a given bit-depth.
E_clip (float) – Maximum exposure level.

Returns:

Linear data \(X_{RIMM}\).

Return type:

numpy.ndarray

Notes

Domain *	Scale - Reference	Scale - 1
`X_p`	[0, 1]	[0, 1]

Range *	Scale - Reference	Scale - 1
`X`	[0, 1]	[0, 1]

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