colour.msds_zeros¶

colour.msds_zeros(labels: Sequence, shape: colour.colorimetry.spectrum.SpectralShape = SPECTRAL_SHAPE_DEFAULT, **kwargs: Any) → colour.colorimetry.spectrum.MultiSpectralDistributions[source]¶

Return the multi-spectral distributionss with given labels and given spectral shape filled with zeros.

Parameters

labels (Sequence) – Names to use for the colour.SpectralDistribution class instances.
shape (colour.colorimetry.spectrum.SpectralShape) – Spectral shape used to create the multi-spectral distributions.
kwargs (Any) – {colour.msds_constant()}, See the documentation of the previously listed definition.

Returns

Zeros filled multi-spectral distributions.

Return type

colour.MultiSpectralDistributions

Notes

By default, the multi-spectral distributions will use the shape given by colour.SPECTRAL_SHAPE_DEFAULT attribute.

Examples

>>> msds = msds_zeros(labels=['a', 'b', 'c'])
>>> msds.shape
SpectralShape(360.0, 780.0, 1.0)
>>> msds[400]
array([ 0.,  0.,  0.])
>>> msds.labels  
['a', 'b', 'c']
