Reading a PNG image in Node.js

Question

Is there an easy way in Node.js to read a PNG file and get the pixels of the image? Something like node-image, but the other way :)

I went through the libraries listed a

Answer 1

I was about to became mad searching, but I found one:

png.js ― A PNG decoder in JS for the canvas element or Node.js.

var PNG = require('png-js');

var myimage = new PNG('myimage.png');

var width  = myimage.width;
var height = myimage.height;

myimage.decode(function (pixels) {
    //Pixels is a 1D array containing pixel data
});

Please note it's pure JavaScript. Works both in the browser and in Node.JS.

There are more properties apart from width and height, see this source.
