Usage Details and Discussion
txt2ti3 takes the Gretag/Logo/X-Rite/Barbieri/etc. 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 one of these formats,
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, inside an ICC tag.
A variety of different packaging of Gretag/Logo/X-Rite/Barbieri 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
X-Rite ColorPort seems to produce a single source file containing
combined device value and CIE and/or spectral values.
The Gretag/Logo test chart results format seem to change with each
minor release of Profile Maker, so this tool may not work in all
Use the Barbieri .CIE file
The outbasefile is the
base of the output file(s), to which txt2ti3 will automatically
append a .ti3 and .ti2 extension.
The input files may have data that is scaled to one of three levels:
1.0, 100.0 or 255.0, and txt2ti3 attempts to guess what the
appropriate range is, in order to scale to Argyll's standard range 0
If the -T flag is used, then the patch location will be transposed
from letter/number to letter/numer - i.e.
B5 -> E2
