Constructors

SpectralData(int[], float[], ScanMode)

Constructs a SpectralData instance from 10 nm spectral reflectance values.

public SpectralData(int[] lambda, float[] value, ScanMode mode = ScanMode.M2)

Parameters

lambda int[]

Wavelength values

value float[]

Spectral reflectance values. Each entry i in this array corresponds to a wavelength value in lambda at the same index.

mode ScanMode

Scan mode for this measurement.

Properties

Interval

Wavelength spacing (eg - 10 nm)

public int Interval { get; }

Property Value

int

Lambda

Wavelength values. Each entry i in this array corresponds to a spectral value in Value at the same index.

public int[] Lambda { get; }

Property Value

int[]

Mode

Scan mode for this measurement.

public ScanMode Mode { get; }

Property Value

ScanMode

Value

Spectral reflectance values. Each entry i in this array corresponds to a wavelength value in Lambda at the same index.

public float[] Value { get; }

Property Value

float[]

Methods

Interpolate(float)

Provides an interpolated reflectance value at a specified wavelength value using natural cubic spines. The cubic splines are evaluated at the points specified by Lambda and Value. Interpolated values are evaluated using natural cubic splines.

public float Interpolate(float lT)

Parameters

lT float

Wavelength (nm) at which to query the interpolated reflectance

Returns

float

Interpolated reflectance value at lT

ToColorData(ReferenceWhite, ColorType)

Provides color data from this measurement for the specified illuminant and observer white point. Result is null if an invalid white point is specified.

public IColorData ToColorData(ReferenceWhite reference = ReferenceWhite.D50_2, ColorType type = ColorType.CIEXYZ)

Parameters

reference ReferenceWhite

Selected reference white (defaults to D50_2)

type ColorType

Output color type (defaults to CIEXYZ)

Returns

IColorData

Color data, or null if an invalid white point is specified
