colour.models.cctf_encoding_ROMMRGB#

colour.models.cctf_encoding_ROMMRGB(X: ArrayLike, bit_depth: int = 8, out_int: bool = False) → NDArrayReal[source]#

Define the ROMM RGB encoding colour component transfer function (Encoding CCTF).

Parameters:

X (ArrayLike) – Linear data \(X_{ROMM}\).
bit_depth (int) – Bit-depth used for conversion.
out_int (bool) – Whether to return value as int code value or float equivalent of a code value at a given bit-depth.

Returns:

Non-linear data \(X'_{ROMM}\).

Return type:

numpy.ndarray

Notes

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

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

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