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> <br> <br> </body> </html>
