Library for encode and decode avif image with libavif & wasm
npm install libavif-wasmfork https://github.com/saschazar21/webassembly
- [x] support ts
- [x] support browser and node
- [x] support more encode/decode options
- [ ] not support encode from file, convert file to pixels is very complex, so you should use other 3rd lib.
