I’m trying to crop a Folium map to a specific area but I can’t get it to work. I made a rectangle on the map, and I want to save a png with just that area.

xlim = (df['longitude'].min(), df['longitude'].max())
ylim = (df['latitude'].min(), df['latitude'].max())
min_lon, max_lon = xlim
min_lat, max_lat = ylim
map = folium.Map(min_lat=min_lat, max_lat=max_lat, min_lon=min_lon, max_lon=max_lon,
                     zoom_control = False, control_scale=False, max_bounds=True)

folium.Rectangle(bounds=[[min_lat, min_lon], [max_lat, max_lon]], color='red', fill=False).add_to(map)
map.fit_bounds([[min_lat, min_lon], [max_lat, max_lon]])
map.save(...)

How can I save just the Rectangle object, cutting out everything arround it?

I tried using cv2 to use computer vision to find the red rectangle and crop it out, but it did not work for all maps since there are other red elements.
