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')
|

and at the end of draw():
|

gif_export(GifMaker)
