Alexandre B A Villares http://abav.lugaralgum.com - GPL v3 | ||
Version 180811 | ||
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) | ||
