- colour.XYZ_to_sRGB(XYZ: ArrayLike, illuminant: ArrayLike = CCS_ILLUMINANTS['CIE 1931 2 Degree Standard Observer']['D65'], chromatic_adaptation_transform: Union[Literal['Bianco 2010', 'Bianco PC 2010', 'Bradford', 'CAT02 Brill 2008', 'CAT02', 'CAT16', 'CMCCAT2000', 'CMCCAT97', 'Fairchild', 'Sharp', 'Von Kries', 'XYZ Scaling'], str] = 'CAT02', apply_cctf_encoding: bool = True) numpy.ndarray [source]¶
Convert from CIE XYZ tristimulus values to sRGB colourspace.
- Parameters
XYZ (ArrayLike) – CIE XYZ tristimulus values.
illuminant (ArrayLike) – Source illuminant chromaticity coordinates.
