Description Gets the value of the spectrum at the given wavelength. If the wavelength provided lies outside of the spectrum's wavelength range, then the returned value is zero. If the spectrum is a sampled spectrum and the wavelength provided is not an exact sample point, then the returned value is a linear interpolation.
Syntax value = SpectrumGetValue( spectNode, wavelength )
Parameters value (Double) Value of the spectrum at the given wavelength.
spectNode As Long Node number of the spectrum being queried.
wavelength As Double Wavelength for which the value is returned.
Example The following example gets the value of a spectrum at 0.5 microns and prints the result to the output window.
Dim value As Double
value = SpectrumGetValue( spectNode, 0.5 ) Print "Value is: " & value
