I had a conversation with Marti Maria about a possible lcms2 bug (possibly
broken absolute colorimetric rendering intent).
He asked me to send my profile. Here is the package:
http://www.tar.hu/janos666/abstest.rar
It includes my spectral measurement data (and a spec2cie converted version
from the ti3 file), my colorprof settings and the resulted ICM file.
He inspected my problem and his judge was that lcms2 works fine because my
display has D93 white point. (And the very brownish result is correct for my
display.)
But it's impossible, because this is is a factory calibrated display. It
can't be so far from D65.
According to the spec2cie converted measurement data, my white point is:
X=93.943
Y=100.00
Z=105.17
So, why does it look like that my WP is D93?
I have no idea, except that there is a bug in ArgyllCMS / colorprof. (I am
using v1.3.2)
As you can see, I used my original ti3 file, the spec2cie result stands for
debugging purposes only. And I didn't use any tricky or strange build
settings, I think.
