Generate Canvas of Pixels Placed by Certain Users or Instances
Download the log file for canvas (check the pinned post as well in case the link changes)
Grab this snippet of code from Github (if you don't understand this code please DO NOT run it. Never run random code you grabbed from the internet if you can't read it :P)
Make sure you have Python and Python Pillow installed.
Change these variables to suite your needs
python users = None instances = None
The default None
is actually "show me everything", I'm just bad at naming things.
E.g. I want to see the top 10 combined pixel placers, I would
python users = "[email protected] \ [email protected] \ [email protected] \ [email protected] \ [email protected] \ [email protected] \ [email protected] \ [email protected] \ [email protected] \ [email protected]"
and set the instances
to None
This would output this image
You can also set it to show pixels after a certain timestamp (although I haven't tested that properly)

Show pixles after this unix timestamp
start_time = 0
Show specific users (example top 10 pixel placers)
users = "[email protected] \
[email protected] \
[email protected] \
[email protected] \
[email protected] \
[email protected] \
[email protected] \
[email protected] \
[email protected] \
[email protected]"
None specified will show ALL
CASE SENSITIVE!!!
users = None
Instances. None specified will show ALL instances
Example, only show blahaj and lemmy.zip
instances = "lemmy.blahaj.zone lemmy.zip"
instances = None
