colour.models.eotf_RIMMRGB

colour.models.eotf_RIMMRGB(X_p, bit_depth=8, in_int=False, E_clip=2.0)[source]

Defines the RIMM RGB encoding electro-optical transfer function (EOTF / EOCF).

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

Linear data \(X_{RIMM}\).
Return type:

numeric or 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 integer switch, thus the domain-range scale information is only given for the floating point mode.
