Usage Details and Discussion
logo2CGATS takes the Gretag/Logo test chart results, and converts them
into Argyll .ti3 CGATS files.
It is quite common to find profile test chart data from various
standards bodies and industry organizations, in this format, so it is
useful to be able to convert them for use with Argyll. ICC profiles
created using Gretag Profile Maker also commonly contain the test chart
results embedded in the profile.
A variety of different packaging of Gretag/Logo data can be accepted:
1 source files, consisting of a combined device value and CIE
and/or spectral values.
2 source files, consisting of a file containing the device
values, and a file containing the CIE and/or spectral values.
2 source files, consisting of a file containing the device values and
the CIE values, and a file containing the spectral values.
3 source files, consisting of a file containing the device values, a
file containing the CIE values, and a file containing the spectral
values.
The Gretag/Logo test chart results format seem to change with each
minor release of Profile Maker, so this utility may not work in all
cases.
