colour.models.log_decoding_ERIMMRGB¶
- colour.models.log_decoding_ERIMMRGB(X_p: Union[FloatingOrArrayLike, IntegerOrArrayLike], bit_depth: Integer = 8, in_int: Boolean = False, E_min: Floating = 0.001, E_clip: Floating = 316.2) FloatingOrNDArray [source]¶
Define the ERIMM RGB log decoding curve / electro-optical transfer function (EOTF).
- Parameters
X_p (Union[FloatingOrArrayLike, IntegerOrArrayLike]) – Non-linear data \(X'_{ERIMM}\).
bit_depth (Integer) – Bit depth used for conversion.
in_int (Boolean) – Whether to treat the input value as integer code value or float equivalent of a code value at a given bit depth.
E_min (Floating) – Minimum exposure limit.
E_clip (Floating) – Maximum exposure limit.
- Returns
Linear data \(X_{ERIMM}\).
- Return type
