Install
-------

```bash
npm install glur
```


API
---

```js
import { blurRGBA, blurMono16 } from 'glur'
```

### blurRGBA(src, width, height, radius)

- __src__ - `Uint8ClampedArray` or `Uint8Array` with RGBA image data (modified in place).
- __width__ - image width.
- __height__ - image height.
- __radius__ - blur radius.

### blurMono16(src, width, height, radius)

Same as above, but input is a grayscale `Uint16Array`. Useful for unsharp mask
via brightness/lightness channel.
