## Summary / 概要

AVIF Image Encoder for JavaScript (only support for browsers, no supports for Node.js/Deno/Bun etc.)

ブラウザ JavaScript で AVIF 画像をエンコーディングするためのスクリプト

## Usage / 使い方

### Install

```bash

# install all sources into "avif-encoder.js" directory in your current path

git clone "https://github.com/m4k15y6666fk/avif-encoder.js.git"

```

### in your JavaScript

```js

// import the module

import Avif from "./avif-encoder.js/dist/index.js";

// initialize the encoder

const avif = new Avif();

await avif.init();

// ...

// ...

// encode image file (File Object) into Uint8Array

// Uint8Array - https://developer.mozilla.org/en-US/docs/Web/API/Uint8Array

const array = await avif.encode(

    file, // File Object - https://developer.mozilla.org/en-US/docs/Web/API/File

    {

        quality: 60,

        speed: 4,

        debug: false

    }

);

// OR

// encode ImageData into Uint8Array

const array = await avif.encode_from_pixels(

    pixels, // ImageData Object - https://developer.mozilla.org/en-US/docs/Web/API/ImageData

    {

        quality: 60,

        speed: 4,

        debug: false

    }

)

```
