MunsellToLab
Converts a
Munsell specification to CIE Lab coordinates, by interpolating over the
extrapolated Munsell renotation data
MunsellToLab( MunsellSpec, white='D65', adapt='Bradford', ... )
MunsellSpec |
a numeric Nx3 matrix with HVC values in the rows, or a vector that can be converted to such a matrix, by row. |
white |
XYZ for the source white - a numeric 3-vector with scaling irrelevant.
|
adapt |
method for chromatic adaptation, see |
... |
other parameters passed to |
The conversion is done in these steps:
HVC → XYZ using MunsellToXYZ()
XYZ is adapted from Illuminant C to the given white
using spacesXYZ::adaptXYZ()
and the given chromatic adaptation method
XYZ → Lab using spacesXYZ::LabfromXYZ()
with the given white
An Nx3 matrix with the Lab coordinates in each row.
The rownames of Lab are copied from the input HVC matrix,
unless the rownames are NULL
and
then the output rownames are the Munsell notations for HVC.
