I’m using Pythonista’s built-in canvas library to draw 2D vector images for a script of mine, but would now like to run my script on a Raspberry Pi or microcontroller. Since canvas is Pythonista-only, I’m wondering if anyone knows how to either export the canvas library for use on other devices, or knows of a good alternative. I already tried Pillow, but since it’s not vector-based, the images it produces do not look as good as what canvas produces.

I mostly just need the ability to draw lines, shapes, and text, and then save the produced image as a png.

@zacbir made a canvas type module that was cross platform

Examples are here (though looks like he later renamed geometer to geometriq, you you might need to change the imports)

I believe this worked with pythonista, MacOS Cairo, maybe pillow and a few others. You'll have to look at what backends you have available on your platform. I think he has some minimal support for svg, but not sure.

If you are looking for other non-python libraries, p5js is easy to learn, and is what the Khan Academy JavaScript course is based on

This is a similar canvas type idea, geared towards animation. You can use the Khan framework for creating your own projects from scratch (you don't have to just do the lessons)
