@jeremydouglass – I’ve done some drawing onto PGraphics. That’s not my favorite approach because (as far as I can tell) I can’t set the pixel density of a PGraphics, so it doesn’t render as crisply as the default graphics context on my Retina MacBook. If there is a way to do this, I’d love to hear it.
But the idea of using get() + save() is certainly simpler than what I’ve been doing, and seems to work great. Thanks for the suggestion!
