cold JS cuts

Getting img pixel data

canvas = document.createElement("canvas"),
ctx = canvas.getContext("2d"); 
	
canvas.className  = "myClass";
canvas.id = "myId";
canvas.width = image.width;
canvas.height = image.height;
	
ctx.drawImage(image, 0, 0); 
pixelData = ctx.getImageData(0, 0, image.width, image.height);

JS namespaces

var yourNamespace = {

    foo: function() {
    },

    bar: function() {
    }
};

...

yourNamespace.foo();
