<h3>Usage Details and Discussion</h3>
txt2ti3 takes the Gretag/Logo/X-Rite/etc. test chart
results, and converts them
into Argyll <a href="File_Formats.html#.ti3">.ti3</a> CGATS files.<br>
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.<br>
<br>
A variety of different packaging of Gretag/Logo data can be accepted: <br>
<br>
1 source files, consisting of a combined device value and CIE
and/or spectral values.<br>
2 source files, consisting of a file containing the device
values, and a file containing the CIE and/or spectral values.<br>
2 source files, consisting of a file containing the device values and
the CIE values, and a file containing the spectral values.<br>
3 source files, consisting of a file containing the device values, a
file containing the CIE values, and a file containing the spectral
values.<br>
<br>
X-Rite ColorPort seems to produce a single source file containing
combined device value and CIE
and/or spectral values.<br>
<br>
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
cases.<br>
<br>
The <span style="font-style: italic;">outbasefile</span> is the base
of the output file(s), to which txt2ti3 will automatically append a
.ti3 and .ti2 extension.<br>
<br>
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 .. 100.0.<br>
