Reorder the axes of given colourspace model \(a\) array according to the most common volume plotting axes order.

Parameters

  • a (ArrayLike) – Colourspace model \(a\) array.

  • model (Union[Literal['CAM02LCD', 'CAM02SCD', 'CAM02UCS', 'CAM16LCD', 'CAM16SCD', 'CAM16UCS', 'CIE XYZ', 'CIE xyY', 'CIE Lab', 'CIE LCHab', 'CIE Luv', 'CIE LCHuv', 'CIE UCS', 'CIE UVW', 'DIN99', 'Hunter Lab', 'Hunter Rdab', 'ICaCb', 'ICtCp', 'IPT', 'IgPgTg', 'Jzazbz', 'OSA UCS', 'Oklab', 'hdr-CIELAB', 'hdr-IPT'], str]) – Colourspace model, see colour.COLOURSPACE_MODELS attribute for the list of supported colourspace models.

  • direction (Union[Literal['Forward', 'Inverse'], str]) – Reordering direction.

Returns

Reordered colourspace model \(a\) array.

Return type

numpy.ndarray

Examples

>>> a = np.array([0, 1, 2])
>>> colourspace_model_axis_reorder(a, 'CIE Lab')
array([ 1.,  2.,  0.])
>>> colourspace_model_axis_reorder(a, 'IPT')
array([ 1.,  2.,  0.])
>>> colourspace_model_axis_reorder(a, 'OSA UCS')
array([ 1.,  2.,  0.])
>>> b = np.array([1, 2, 0])
>>> colourspace_model_axis_reorder(b, 'OSA UCS', 'Inverse')
array([ 0.,  1.,  2.])
