Colorport CGATS to Argyll CTI3 conversion utility

[jejes]

I ned help to compile this app or to find a script in python or something to convert Argyll ti1, ti2 or ti3 to colorport. My goal is to read with my DTP70 the charts i have created in argyll, and i have to read and print in Colorport. I think argyll works from 0 to 100 and colorport works from 0 to 255. But i'm not an expert

Please can anyone help me?
This is the link of a post of a person who does, but i can't contact him

Thank You

I would expect that you are better off on the ArgyllCMS website with related support links.

This txt2ti3 command may be what you are looking for

https://www.argyllcms.com/doc/txt2ti3.html

" Convert Gretag/Logo/X-Rite/Barbieri or other CGATS format RGB or CMYK test chart results into Argyll .ti3 CGATS format. "

Thank you but i need the inverse way, i need from Ti1 or Ti2 to Colorport.

Actually I am looking for something similar to convert to to i1Profiler, because ArgyllCMS is more flexibel into creating the amount of neutral patches/greys within a given amount of patch count. In i1Profiler it is not possible to choose let's say 128 grey steps at will. Only at given patch counts you can approximate that amount of near neutral patches/greys and ArgyllCMS also distribute the measure points more evenly than i1Profiler. I get better greys/neutral steps with ArgyllCMS at a given patch counts compared to i1Profiler, but the ArgyllCMS does not support dual scan mode with the i1Pro2 (UV-cut), but in most cases that is not necessary. Despite the cryptic commands in ArgyllCMS, it is a hell of a program with a myriad of possibilities unmatched by the more rigid i1Profiler. There are a few solutions that build a graphical user interface on top of ArgyllCMS, but I don't like them. I think it could revolutionize its popularity if there is a more user friendly interface that acts and works like i1Profiler.

I have a patch sheet editor as part of my i1Profiler program package which allows me to modify a patchsheet - you can add or remove color patches or relocate them, you just enter patch colors by the RGB value.

Yes, but to enter manually is crazy, or to enter with automation software.

I use everyday argyll but I use a dtp70 to scan the charts and this is the reason, have read the post I linked in the first comment? It’s a c program to compile but I’m not able to do it. It would be nice to collaborate with you and write a python script to convert ti1 or ti2 into Xrite understandable.

My thought is that argyll works with values from 0-100 and Xrite from 0-255

Thank you

If that is the case, the conversion would be multiply with 2.55 and to average to the nearest whole number.

I have coded an script of python to do it. If someone needs please tell me.

I have been playing with this editor. I took me alot of time to introduce the extra desired amount of neutral and near neutral patches into an existing generated 581 patch target to increase it to 700 patches. It is based on the RxGxB patches of 8x8x8 and grey ramp/(near) neutral patches/white/black up to 700.
