Possible to use ChunkyPNG for animated PNGs (APNG)?

[callmeed]

Hello,

I'm wondering if anyone has tried or had luck with using ChunkyPNG to create an animated PNG from a sequence of images.

From what I understand, the APNG format is just an extension to PNG with 3 additional chunks for defining animation settings.

Thanks for any insight into this.

I've not heard of anyone working on this, but I'll happily merge support for the chunk types, and API methods if somebody would offer pull request.

Having said that, APNG support in browsers is poor, so I am not sure if you'd want to use this format over an animated gif. http://caniuse.com/#feat=apng

Since the last comment on this issue, Google added APNG support in 2017 and Microsoft has announced they are switching to a Chromium base for Edge. APNG support in browsers has gotten much stronger.
