/* This program uses display measurements from a colorimeter and */
/* a spectrometer to create a correction matrix for a particular */
/* colorimeter/display combination. */
/* It can aslso be used to make display measurements from a spectrometer to create */
/* spectral calibration samples that can be used with a Colorimeter that */
/* knowns its own spectral sensitivity curves (ie. X-Rite i1d3, Spyder 4). */
/* Based on spotread.c, illumread.c, dispcal.c */
/*
TTBD:
Should change -s to generate more neutral colors as well
as saturated ones.
Would be nice to have a way of not changing the target
instruments absolute calibration.
Would be nice to have a verify option that produces
a fit report of a matrix vs. the input files.
Would be nice to have the option of procssing a Spyder 3 correction.txt file.
(See post from umberto.guidali@tiscali.it)
Would be nice to be able to use an i1D3 to correct other instruments,
or an i1D3 created .ti3 as the reference. (can do this with .ti3 files).
Would be nice to have an option of providing two ICC profiles,
instead of using .ti3 files (?? How well would it work though ?)
