See https://github.com/devsoc-unsw/structs.sh/pull/654

dqna64 commented 3 months ago

Todo:

[x] enable pan even outside the visualiser svg
[ ] enable reset transform (reset pan and zoom)
[x] test pan-zoom consistent on workspace resize (it is currently not)

enabled pan by dragging mouse anywhere within #visualiser-container (workspace) see image Screenshot 2024-06-12 at 04 29 45

Idea for implementation of "allow reset transform" -- use IntersectionObserver to detect when visualiser canvas goes out of workspace, to allow user to reset the pan/zoom and center the visualiser canvas in teh workspace again
