XYZcie1931_from_spd#
- colorsynth.XYZcie1931_from_spd(spd, wavelength, axis=-1)[source]#
Calculate the CIE 1931 tristimulus values, \(XYZ\), for the given spectral power distribution.
- Parameters:
spd (ndarray) – the spectral power distribution of an emitting source as a function of wavelength
wavelength (Quantity) – the wavelength grid corresponding to the spectral power distribution. Must be sorted to yield positive \(XYZ\) values
axis (int) – the wavelength axis, or the axis along which to integrate
- Return type:
