Can I use this to tile an image in a fractal pattern? #16

I want to start with a base image (my company's logo) and tile it following a fractal pattern (scale, rotate, translate, modify color).

Is that possible?

Short answer: yes you can, but in sort of very undocumented and likely to be changed way. You need to get cairo context object from pycontextfree, currently it is in pycontextfree._state["ctx"] , and use it to draw an image with cairo API. You can wrap this in contextfree's check_limits etc decorators, they are pretty much agnostic about what is happening inside. I'll try to make some example a but later when I get minute.

Awesome, that sounds really useful. I will be on the lookout for an example when you get the time.
