sd_constant
(k, shape=SpectralShape(360, 780, 1), dtype=<class 'numpy.float64'>)[source]¶ Returns a spectral distribution of given spectral shape filled with constant \(k\) values.
Parameters: - k (numeric) – Constant \(k\) to fill the spectral distribution with.
- shape (SpectralShape, optional) – Spectral shape used to create the spectral distribution.
- dtype (type) – Data type used for the spectral distribution.
Returns: Constant \(k\) to filled spectral distribution.
Return type: Notes
- By default, the spectral distribution will use the shape given by
colour.DEFAULT_SPECTRAL_SHAPE
attribute.
Examples
>>> sd = sd_constant(100) >>> sd.shape SpectralShape(360.0, 780.0, 1.0) >>> sd[400] 100.0
