JSON-G (JSON-Graphics) is an extremely inefficient way to store raster image data, with transparency and layered support!

• None!

This results in the following image, when converted to PNG:

...and here it is blown up, because that last one is far too small to look at and appreciate.

The rest of this repo contains specifications for how to read/write JSON-G, some sample JSON-G files as well as a PNG ⇌ JSON-G converter written in Python as a proof of concept.

There is also a resources page showcasing JSON-G libraries created by others in various languages. If you make one, feel free to PR a link to it on that page!

I'd have called it JSONP if it hadn't already been taken, so JSON-G was the next best thing. I put a dash in between the JSON and G so people wouldn't pronounce it as J-song and hopefully avert another file-extension pronunciation war.

Do whatever you want tbh.

I am absolutely sorry for doing this

Sounds like a waste

Credit to Gorialis for helping me test the spec and my converters.

Also HpslUU who gave me the whole idea for doing this anyway (and creating a GitHub account just so I could type this line).
