Hi,
        it's pretty reasonably priced as far as research articles go ($12),
and publishing in a journal in the technical area _is_ sharing it with
the community. [There are a lot less accessible journals in this area
- go look at the subscription rates to Wiley's "Color research and
application" for instance. It will make your eyes water...]

By default they are absolute. You can choose various relative
versions in spotread :- ie. for relative to the display
white, use -dw, and you then have to calibrate it against
the white before taking measurements.]

I think it is possible, but you need to set the ARGYLL_NOT_INTERACTIVE
environment variable. See
