public SpectralData SpectralData(IntArray lambda, FloatArray value, ScanMode mode)

Properties

private final Integer interval

Wavelength spacing (eg - 10 nm)

Link copied to clipboard
private final IntArray lambda

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

Link copied to clipboard
private final ScanMode mode

Scan mode for this measurement (one of ScanMode.M0, ScanMode.M1, or ScanMode.M2)

Link copied to clipboard
private final FloatArray value

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

Functions

public Integer getInterval()

Wavelength spacing (eg - 10 nm)

Link copied to clipboard
public IntArray getLambda()

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

public ScanMode getMode()

Scan mode for this measurement (one of ScanMode.M0, ScanMode.M1, or ScanMode.M2)

public Float interpolate(Float lT)

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 IColorData toColorData(Illuminant illuminant, Observer observer, IColorData.ColorType type)
public IColorData toColorData(ReferenceWhite reference, IColorData.ColorType type)

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

@ColorInt()
public Integer toColorInt(ReferenceWhite reference)
@ColorInt()
public Integer toColorInt(Illuminant illuminant, Observer observer)

Provides an sRGB value for this measurement for the specified illuminant and observer white point. Result is null if an invalid white point is specified.
