		## Install

		## install
		``` sh
		$ npm install get-image-data
		npm install get-image-data [sharp]
		```
		note: canvas is not installed alongside get-image-data

		get-image-data requires [automattic/node-canvas](https://github.com/automattic/node-canvas) for its server/node variant, however, to avoid browser-only users from having to endure the native compilation process, it needs to be npm installed separately.


		## Usage

		### Browser & Server
		## use
		``` js
		var image = require('get-image-data')

		image('./image.jpg', function(error, info) {
		image('./image.jpg', function (err, info) {
		var data = info.data
		var height = info.height
		var width = info.width
		var data = info.data

		@@ -36,9 +29,14 @@ for (var i = 0, l = data.length; i < l; i += 4) {
		})

		// Extract data faster with `sharp`
		var image = require('get-image-data/native')
		```

		### Note
		The image data will be contained within either a [Uint8ClampedArray](https://developer.mozilla.org/en-US/docs/Web/API/Uint8ClampedArray) or a [CanvasPixelArray](https://developer.mozilla.org/en-US/docs/Web/API/CanvasPixelArray) depending on the environment. This shouldn’t be a problem, but it’s worth knowing.
