When I do the following command on a PNG:
exiftool -a -s AnselTest.png
I get the following output:
https://i.imgur.com/YDNjUxq.png (https://i.imgur.com/YDNjUxq.png)
However, if I try to modify the values for tags 'DRSProfileName' or 'DRSName', exiftool returns:
Warning: Tag 'DRSProfileName' is not defined
I also cannot assign this tag any value in a seperate PNG, for the same reason.
Some more context: This is a PNG generated by nVidia's Ansel Software, and is an in-game screenshot from the game 'Space Engineers'.
Is there anyway to enable editing of this tag? If this is not possible, can I create my own tag of the same name, and input strings as the values?
Add the -G1 option to your command to show the location of this tag. What is the location?

Adding the -G1 tag shows this result

It appears to be part of the PNG group
OK, thanks.
You will need to create a user-defined PNG tag to be able to write this. See the user-defined PNG tags (NewPngTag1, etc) in the example config file (https://exiftool.org/config.html) for an example of how to do this.
