Currently you can do that by updating the perimeter's shape in the "postprocessing" function, but I'm planning to add aspect ratio as a parameter for the prettymaps.plot function

Thank you

Could you maybe provide a short example how to do this with postprocessing?
I tried modifying layers["perimeter"].bounds, but I guess it might be a problem that shapely geometry objects have become immutable as of v2.0: https://shapely.readthedocs.io/en/stable/migration.html#geometry-objects-will-become-immutable

Hey @generativearts & @danielwiegand did you ever figure out how to do this?

@till-m No. I ended up generating a quadratic image and changing the aspect ratio by means of Gimp.

any updates on this?
