No - thank you for the hint. This sounds very promising. But i do not
want to pay for this PDF without knowing if i could use the content. It
would be nicer if he would share his findings with the community like
others do ;-)
But if somebody has a copy of it i would be glad if i could get it.
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...]

And get the following output for a white color:
Result is XYZ: 132.247557 139.842979 120.663127, D50 Lab: 113.719384
-3.601868 -3.378244
Are these XYZ values in a relative or absolute form?
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.]

Ok. Great.

spotread: Error - tcgetattr failed with 'Invalid argument' on stdin
I assume its not possible to use spotread without a shell and to tell it
to read its input from a stream instead?
I think it is possible, but you need to set the ARGYLL_NOT_INTERACTIVE
environment variable. See
<http://www.argyllcms.com/doc/Environment.html>

Thanks for the hint! Now its working for me [1] :-)
I also had to update to the new Argyll version (Ubuntu comes only with 1.1.0-5) and set the "HOME" user variable.

Best regards,
Hendrik
