Alexandre B A Villares http://abav.lugaralgum.com - GPL v3
A helper for the Processing gifAnimation library (https://github.com/jordanorelli)
ported to Processing 3 by 01010101 (https://github.com/01010101)
Download the library from https://github.com/01010101/GifAnimation/archive/master.zip
This helper was inspired by an example by Art Simon https://github.com/APCSPrinciples/AnimatedGIF/
Put at the start of your sketch:
add_library('gifAnimation')
from gif_exporter import gif_export
and at the end of draw():
gif_export(GifMaker)
