How do I integrate the xyzfix resulting matrix in the hcfr.c code? What are
xmat and tmat in this file?
In what order do I have to call the .ti3 files in xyzfix?
BTW, as I can't make HCFR colorimeter work under linux, could send be a
pre-compiled version of dispwin (I guess I only need this one) compiled
with #define MEASURE_RAW, for windows (I'll make the calibration under
this OS)?
Thanks,
