Question: is there a way to rotate around an arbitrairy point? (not the center) #36

Hi there,

Great plugin, works as promised and i'm a happy user.

But we are building some sort of navigation app, and we want to rotate the map around a point in the bottom center of the map. This way you see a lot of the map ahead of you and not so much of the roads that have passed. (which in our case is usefull)

Am I missing an option? should I use some trickery? or is it simply not possible?

I'm not 100% sure but (out of the box) I don't think so .

In any case, there are already many utility functions within the L.Map class that you can also use as a starting point to achieve that goal.

For example:

thanks, I'll have to dive into that. The lingo of leaflet is new to me. Lots of inheritance but hard to figure out where there the actual code is 🤣
