feature request to suppor .cal files and read current gpu gamma table

[Vincent]

IDNK of such free tool, I thought apply cal acted on VCGT and not in TRC.

Maybe you can get some other matrix profile (No CHAD PCS d50 white), replace primaries & white coordinates & TRC with the “before” profile you have and then replace VCGT contents with yours (need to scale to 16bit int). A lot of HEX editor work.

well i hope someone can help out here then , im surprised im the only one …except for that other guy in said thread that wants this functionality  even more so absolutely needs it, anybody got a good solution …without a colorimeter or tons of hex editing …would appreciate , been at this for quite a while and still am looking for that solution , means alot to me

[subalternpushing]

still would appreciate it

so i might have a way ….per batch and .vbs magic and having calibration tools use a day and night separate perma file , BUT i need someone to help out to give me a solution how to either per powershell  or other way to detect current display being rendered to ….like DisplayCAL is able to detect , heres my powershell thread….that currently aint getting nowhere , would appreciate

ok with some more feedback and a generous dev …FINALLY !!!

full synthetic VCGT.cal into icm importing and exporting !! it works so damn good now, this from the dev >

Looks like you are in luck – the COVID-19 lockdown here has delayed some
deadlines, so I managed to spend a few hours working on a new tool.

You can find the Win10 binary here:
<https://www.argyllcms.com/win64_V2.2.1beta_iccvcgt.zip&gt;

Doco is here: <https://www.argyllcms.com/doc/iccvcgt.html&gt;

Hope this does what you are looking for.

put resulting .icm Profile aka output.icm renamed to your preference… into C:\Windows\System32\spool\drivers\color

make sure to name your file names accordingly aka VCGT.cal to curves.cal , random synthetic icm profile aka input profile …and thats it

[subalternpushing]

my request now would be for an option to set the autoload and force profile only for certain displays, would make this perfect
