Thanks for this, just got this working with only a few tweaks. First I had to add the width and the height to the constructor for GIF. Then I could not get the window.open thing to work so I had to make a link to the ObjectURL instead. It means I have to click a link to get the gif to save, but that is fine with me! Thanks again and I hope this helps anyone trying to get this working!
@Torwegia any chance of sharing how you did the link to save the gif?
bump, I'm having an issue where gif.on('finished') never triggers.
