# spectral10ToDensity

public final DoubleArray spectral10ToDensity(IntArray lambda, FloatArray reflectance, DensityStatus status)

Takes reflectance data on 10 nm intervals and calculates CMYK densities according to ISO 5-3:2009. Data must be provided on 10 nm intervals corresponding to the nearest 10 nanometer. Density values are calculated across the range 340 - 770 nm. If the provided data spans a shorter range (eg - 400 - 700 nm), the values at the boundaries are repeated.

#### Return

CMYK densities (element order C, M, Y, K)

#### Since

4.0.2

#### Parameters

lambda

Wavelength values of provided reflectance data.

reflectance

Reflectance data. Must contain the same number of elements as lambda

status

Selected density status
