colour.sd_constant#

colour.sd_constant(k: float, shape: SpectralShape = SPECTRAL_SHAPE_DEFAULT, **kwargs: Any) SpectralDistribution[source]#

Return a spectral distribution of given spectral shape filled with constant \(k\) values.

Parameters:
  • k (float) – Constant \(k\) to fill the spectral distribution with.

  • shape (SpectralShape) – Spectral shape used to create the spectral distribution.

  • kwargs (Any) – {colour.SpectralDistribution}, See the documentation of the previously listed class.

Returns:

Constant \(k\) filled spectral distribution.

Return type:

colour.SpectralDistribution
