Thanks. I read through those before posting, but didn’t see anything about using UIBezierPath with canvas. Those posts all seemed to be about working with ui. I used canvas because it’s a static 2D context like the one in DrawBot. Are you suggesting that it would be better to build atop ui instead of canvas? I just looked back through the ui docs and it looks like I could build a custom DrawBotView that presents the output image. (This post is helpful.)

Thanks again for the help. I’ve done tons of PyObjC work on the Mac and have used Pythonista on my iPad for a few years, but this is the first time I’m trying to do anything *visual *with Pythonista. I’m just trying to get some code development visualization working across devices... :)
