Install

``bash`
npm install glur --save
API
---
require('glur')(src, width, height, radius)
- __src__ - typed array with image RGBA data (will be updated with blured image).
- __width__ - image width.
- __height__ - image height.
- __radius__ - blur radius.
require('glur/mono16')(src, width, height, radius)` - the same as above, but
input data is grayscale Uint16Array. Can be useful to calculate unsharp mask via
brightness/ligthness channel.
