Printer Profile Validation: M1 vs. M2 and ΔE2000 Evaluation

[itsab1989]

Issue1: The command boxes begin to appear before the next working screen is displayed

After the ICC profile is built:
Click Create Chart.
Change the Run Type to Verification.
Observe the attached video.


Issue 2: Fixed Seed Is Not Saved in Preset

Preset files are stored in the following directory:
\Users\UserName\AppData\Roaming\ChromIQ\presets

Example file: 1Pro-4x6in-192p-2pages.json

Currently, the preset file contains the following values:

"randomize": true,
"seed": null,
"seed_fixed": null

Expected behavior:

If the user defines a seed value (e.g., 1234), the preset file should save that value in the seed field:

"randomize": true,
"seed": 1234,
"seed_fixed": null

The user-defined seed value should be saved correctly in the preset file and retained when the preset is loaded again.



.../2 zips are attached

That's really strange. I will see what I can do about it

Edit:

Edit 2:

Fixed:

Nice catch We have not seen anything like that before, so it is good that some more people, like you, help out with reporting bugs

Thanks.
