Syntax
public class SpectralData : ISpectralData
Constructors
SpectralData(int[], float[], ScanMode)
Constructs a SpectralData instance from 10 nm spectral reflectance values.
Declaration
public SpectralData(int[] lambda, float[] value, ScanMode mode = ScanMode.M2)
Parameters
Type | Name | Description |
---|---|---|
int[] | lambda | Wavelength values |
float[] | value | Spectral reflectance values. Each entry |
ScanMode | mode | Scan mode for this measurement. |
Properties
Interval
Wavelength spacing (eg - 10 nm)
Declaration
public int Interval { get; }
Property Value
Type | Description |
---|---|
int |
Lambda
Wavelength values. Each entry i
in this array corresponds to a spectral value in Value at the same index.
Declaration
public int[] Lambda { get; }
Property Value
Type | Description |
---|---|
int[] |
Mode
Scan mode for this measurement.
Declaration
public ScanMode Mode { get; }
Property Value
Type | Description |
---|---|
ScanMode |
Value
Spectral reflectance values. Each entry i
in this array corresponds to a wavelength value in Lambda at the same index.
Declaration
public float[] Value { get; }
Property Value
Type | Description |
---|---|
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.
Declaration
public float Interpolate(float lT)
Parameters
Type | Name | Description |
---|---|---|
float | lT | Wavelength (nm) at which to query the interpolated reflectance |
Returns
Type | Description |
---|---|
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.
Declaration
public IColorData ToColorData(ReferenceWhite reference = ReferenceWhite.D50_2, ColorType type = ColorType.CIEXYZ)
Parameters
Type | Name | Description |
---|---|---|
ReferenceWhite | reference | Selected reference white (defaults to D50_2) |
ColorType | type | Output color type (defaults to CIEXYZ) |
Returns
Type | Description |
---|---|
IColorData | Color data, or |
