colour.log_decoding

colour.log_decoding(value: ArrayLike, function: LiteralLogDecoding | str = 'Cineon', **kwargs: Any) → NDArrayFloat

Apply the specified log decoding inverse opto-electronic transfer function (OETF).

Parameters:

• value (ArrayLike) – Logarithmic encoded value.

• function (LiteralLogDecoding | str) – Log decoding function.

• kwargs (Any) – {colour.models.log_decoding_ACEScc(), colour.models.log_decoding_ACEScct(), colour.models.log_decoding_ACESproxy(), colour.models.log_decoding_AppleLogProfile(), colour.models.log_decoding_ARRILogC3(), colour.models.log_decoding_ARRILogC4(), colour.models.log_decoding_CanonLog2(), colour.models.log_decoding_CanonLog3(), colour.models.log_decoding_CanonLog(), colour.models.log_decoding_Cineon(), colour.models.log_decoding_DJIDLog(), colour.models.log_decoding_ERIMMRGB(), colour.models.log_decoding_FLog(), colour.models.log_decoding_FLog2(), colour.models.log_decoding_FilmicPro6(), colour.models.log_decoding_LLog(), colour.models.log_decoding_Log2(), colour.models.log_decoding_Log3G10(), colour.models.log_decoding_Log3G12(), colour.models.log_decoding_MiLog(), colour.models.log_decoding_NLog(), colour.models.log_decoding_PivotedLog(), colour.models.log_decoding_Panalog(), colour.models.log_decoding_Protune(), colour.models.log_decoding_REDLog(), colour.models.log_decoding_REDLogFilm(), colour.models.log_decoding_SLog(), colour.models.log_decoding_SLog2(), colour.models.log_decoding_SLog3(), colour.models.log_decoding_FilmLightTLog(), colour.models.log_decoding_VLog(), colour.models.log_decoding_ViperLog()}, See the documentation of the previously listed definitions.
