Hello,

Playing around with the MapJs Snapshot API. How many individual Overlays can it support? The docs say max for Images is 10 but not listing number of Overlays/Annotations it can support.

Trying to generate a gradient path like so:

But it seems the Apple Snapshot api only allows for 10 unique Overlay objects, is that true?

Also, what's the max size of a Snapshot query url? Seems to stop working around 5,000 characters but Google allows for 8000+

It seems that even Apple's own Activity app would like this feature, too.

When you go to export a GPS workout from Apple's Activity app, it actually screenshots the Javascript map with the gradients, presumably because calling the Snapshot API would not work with > 10 gradient values.

Ex:
