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/

add_library('gifAnimation')
