Img is a repo containing implemenetations, made from scratch, of various image formats offering the ability to encode and decode between them, and integrate smoothly with various Web APIs like the Canvas. Where possible, we offer both sync and streaming encoders/decoders.
If this repo is missing a format you'd like to work with, simply create an issue suggesting the format, along with a link to the standard, specifcation or some document that is essentally the source of truth for that format. Do that and it might get an implementation here.
