I remade 2 mathmap appimages for Ubuntu 20.04 and 22.04.

The 'focal' appimage
Compiled on Ubuntu Mate and tested on 20.04 systems. The appimage launches the installed Gimp (either system or ppa) and adds MathMap under Filters > Generic > Mathmap > MathMap. This location has animation filters.

Issue with GTK3 systems like Mate. You have to manually expand the MathMap window due to MathMap only supporting GTK2. Xubuntu has all window controls. This image does not work on later 22.04 jammy systems.
This is experimental software use at your risk but is pretty safe as it's only a 7mb appimage. Make executable before using.

The appimages are here.

Woowwww!!

It works like a charm on Ubuntu-MATE 20.04, even the window default size is perfect, resizing is not a problem if needed as it resize as it should (even the Alt+right click+ drag does its job properly)

Thank you very much Tas_mania
I did not recall there were so much thing inside MathMap, this will take quite a while before trying everything

Default size (MathMap/Map/Radial Displace)


Manually resized


Even in the middle the resize is working horizontally, also when needed it shows the horizontal bar below the user values to access the "Default" button


Again thanks a lot Tas_mania

Hi Patrice, I'm glad it's working now and thanks for sending me in that direction. It's an old app and it's been hard keeping it up to date. Maybe I'll be able to convert to GTK3 some time.

I only use it for animation and I woke-up last night with this idea -


I think I could use it when I see 'spam' and free advertising for this <consumer> product

BTW I made my avatar with MathMap.
