Create .icc profile from .cal file

[aorefice]

Hi,

I don’t own any hardware calibrator, but i made a graphical tool that helps in manually creating calibration curves/values (similar to Atrise Lutcurve 4) and export them in the .cal format that dispwin is able to read, so i can apply my custom made video luts to the monitor.

My system color manager don’t seem to care about the lut i manually loaded and it resets them every now and then (for example when i change resolution, refresh rate).

So, I’d like now to create an icc profile out of .cal file, so that my system color manager can automatically load them at login and keep them loaded.

I tried with applycal

applycal /path/to/my/file.cal /usr/share/DisplayCAL/presets/sRGB.icc /path/to/output/profile.icc

It produced /path/to/output/profile.icc, and if i inspect it, i see that the data is in there, but when i try to load it via dispwin or via the system color manager, the lut is just the default one, and not the one from /path/to/my/file.cal

Maybe applycal is not the right tool to do what i’m trying to.

Is there a way?

Thank you in advance.

Mmh, i was wrong about the cal file being inserted into the icc profile by applycal.

it seems applycal blindly inserts a linear ramp into the profile ignoring the cal file generated by “dispwin -s”

What am i doing wrong, isn’t the file produced by dispwin -s the one expected by applycal maybe?

Sorry guys, the tool was iccvcgt.
iccvcgt -i old.icc new.cal new.icc
worked fine.
