get-pixels
==========
Given a URL/path, grab all the pixels in an image and return the result as an [ndarray](https://github.com/mikolalysenko/ndarray). Written in 100% JavaScript, works both in browserify and in node.js and has no external native dependencies.
Currently the following file formats are supported:
* `PNG`
* `JPEG`
* `GIF`
Example
=======
```javascript
var getPixels = require("get-pixels")
getPixels("lena.png", function(err, pixels) {
if(err) {
console.log("Bad image path")
return
}
console.log("got pixels", pixels.shape.slice())
})
```
Install
=======
npm install get-pixels
### `require("get-pixels")(url[, type], cb(err, pixels))`
Reads all the pixels from url into an ndarray.
* `url` is the path to the file. It can be a relative path, an http url, a data url, or an [in-memory Buffer](http://nodejs.org/api/buffer.html).
* `type` is an optional mime type for the image (required when using a Buffer)
* `cb(err, pixels)` is a callback which gets triggered once the image is loaded.
**Returns** An ndarray of pixels in raster order having shape equal to `[width, height, channels]`.
**Note** For animated GIFs, a 4D array is returned with shape `[numFrames, width, height, 4]`, where each frame is a slice of the final array.
