Create a generic_spct object with wavelengths from the range of wavebands in a list. The spectrum is suitable for plotting labels, symbols, rectangles or similar, as the midpoint of each waveband is added to the spectrum.
wb2rect_spct(w.band, short.names = TRUE, chroma.type = "CMF")fast_wb2rect_spct(w.band, chroma.type = "CMF", simplify = TRUE)
A generic.spectrum
object, with columns w.length, wl.low,
wl.hi, wl.color, wb.color and wb.name. The w.length values are the
midpoint of the wavebands, wl.low and wl.high give the boundaries of the
wavebands, wl.color the color definition corresponding to the wavelength at
the center of the waveband and wb.color the color of the waveband as a
whole (assuming a flat energy irradiance spectrum). Different spectral data
variables are set to zero and added making the returned value compatible
with classes derived from generic_spct
.
waveband or list of waveband objects The waveband(s) determine
the wavelengths in variable w.length
of the returned spectrum
logical Flag indicating whether to use short or long names for wavebands
character telling whether "CMF", "CC", or "both" should be
returned for human vision, or an object of class chroma_spct
for any
other trichromic visual system.
logical Flag indicating whether to merge neighboring rectangles of equal color. Simplification is done only for narrow wavebands.
