# MangaRock Image Decoder

> Decode images from MangaRock's proprietary format

MangaRock has a nice API to work with, but obscures images by [encoding them as bitwise xor'd .webp images](https://www.reddit.com/r/codes/comments/7mdx70/need_help_decrypting_this_string/). This codebase is a web microservice that decodes images into their native .webp format for easy consumption outside of MangaRock.

This microservice was built for the [poketo library](https://github.com/poketo/node).

## Usage

This package is available on npm, or as a microservice deployed to `https://mri-image-decoder.now.sh`. To use the microservice, pass the image's URL to the `?url` query parameter like so:

```
https://mri-image-decoder.now.sh?url=https://f01.mrcdn.info/file/mrfiles/i/6/n/l/T3.3BZTN7p5.mri
```

This will return the image with the correct content type set, so you can simply load or use it like any other image URL:

```html
<img src="https://mri-image-decoder.now.sh?url=https://f01.mrcdn.info/file/mrfiles/i/6/n/l/T3.3BZTN7p5.mri" />
```

### JS API

To use this package from npm, install it:

```bash
npm install manga-rock-image-decoder
```

This package exports a single function, `decode` which accepts a .mri image buffer and returns a converted .webp buffer

```js
const decode = require('manga-rock-image-decoder');

const webpImageBuffer = decode(mriImageBuffer);
```

You can use an image conversion tool, such as [sharp](https://www.npmjs.com/package/sharp), to convert the .webp image to
