cctf_decoding_RIMMRGB
(X_p, bit_depth=8, in_int=False, E_clip=2.0)[source]¶ Defines the RIMM RGB decoding colour component transfer function (Encoding CCTF).
- 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
