colour.RGB_to_RGB¶
- colour.RGB_to_RGB(RGB: ArrayLike, input_colourspace: colour.models.rgb.rgb_colourspace.RGB_Colourspace, output_colourspace: colour.models.rgb.rgb_colourspace.RGB_Colourspace, 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_decoding: bool = False, apply_cctf_encoding: bool = False, **kwargs: Any) numpy.ndarray [source]¶
Convert given RGB colourspace array from given input RGB colourspace to output RGB colourspace using given chromatic adaptation method.
- Parameters
RGB (ArrayLike) – RGB colourspace array.
input_colourspace (colour.models.rgb.rgb_colourspace.RGB_Colourspace) – RGB input colourspace.
output_colourspace (colour.models.rgb.rgb_colourspace.RGB_Colourspace) – RGB output colourspace.
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]) – Chromatic adaptation transform, if None no chromatic adaptation is performed.
apply_cctf_decoding (bool) – Apply input colourspace decoding colour component transfer function / electro-optical transfer function.
apply_cctf_encoding (bool) – Apply output colourspace encoding colour component transfer function / opto-electronic transfer function.
kwargs (Any) – Keywords arguments for the colour component transfer functions.
- Returns
RGB colourspace array.
