Can a graphics state be noted and later restored?

[Simon Katz]

Hi,

Is it possible to make a note of the current graphics state and restore it later?

(Not sure that "graphics state" is the right phrase. I mean stroke, stroke-weight, fill, rect-mode, ellipse-mode etc — all the things that are global and can be changed.)

Hi Simon

No, I don't think there is a way to do it. The closest thing is pushing/popping matrices but it's limited only to transformations and not stroke/fill. Instead you can introduce your own state map with those parameters and write a function that takes this state and sets corresponding values, but it's a bit bulky.

In standard Processing, this is what pushStyle and popStyle accomplish. I'm not sure if/how it's exposed in clj-p, but the mechanism is there in the foundations.
