SUMMARY

STEPS TO REPRODUCE
1. You need a krita file (i.e. file.kra), configured the author profile (other than anonymous) in Configure Krita, and set the Active Author Profile to the author.

2. Save the krita files (either the existing file or new version). 
3. Click on File->Document Information->Author. You will not see author information every time. It is spotty.
4. Export as PNG (say file.png), and you have checked the store metadata and sign with author data. Then use imagmagick command "identify -verbose file.png", you should see the meta data, but no author information is available.

The version of krita I am using is the latest stable 4.4.2 version

OBSERVED RESULT
No document information about author in kra file nor in metadata for png


EXPECTED RESULT
I would like the author information to be stored

SOFTWARE/OS VERSIONS
OS: Linux Ubuntu 20.04

ADDITIONAL INFORMATION
I have placed this as critical because not having author information to preserve copyright and other such details seems like a critical bug. Extremely important to fix.

Reproduced on 5.0.0beta5, Win10, Wacom Intuos 4S PTK-440

Saved as PNG 

The only metadata found is Author: "Will" which is only the author firstname field as configured in the author profile.

Comment 2 Reinold Rojas 2024-11-12 03:44:26 UTC

I am able to save and load author information for .kra files, that seems to be fixed.

I'm not able to save/load author information from PNG files. I also used gimp to checking the loading/saving of author information and Krita was never able to read/save png author information.

Setting to confirmed only for missing .png Author information

STEPS TO REPRODUCE
1. Create an author profile in settings -> configure krita-> author
2. Ensure author profile is active in settings -> active author profile
3. Open .kra file, edit, and save .kra file
4. Check authorship saved in File-> Document information->Author
5. Export as PNG in File-> Export -> Save
6. Enable "Sign with author data" and click ok
7a. Open exported png file in Krita and check authorship again in File ->Document Information->Author (observe author information is blank)
7b. Open png in Gimp. In topbar go to Image->metadata->edit metadata (observe author information is blank)
