In this tutorial, we are going to make a simple web app that allows you to drag a photo from your computer into the browser window, and apply instagram-like filters on it. For this purpose we are going to use a number of JavaScript libraries and plugins:
Caman.js – this is a powerful canvas manipulation library that allows you to apply various effects and filters on an image. It comes with 18 preset filters which we will be using in this example (you can create more if you wish);
Filereader.js – this is a lightweight wrapper around the HTML5 drag/drop events that makes them much easier to work with. It also adds a method to jQuery, so you can bind the events to a specific element;
jQuery Mousewheel – I am using this plugin to scroll the filter container;
In addition, we are using the latest version jQuery at the time of writing.
