Paper.js is an open source vector graphics scripting framework that runs on top of the HTML5 Canvas. It offers a clean Scene Graph / Document Object Model and a lot of powerful functionality to create and work with vector graphics and bezier curves, all neatly wrapped up in a well designed, consistent and clean programming interface.

FEATURES Document Object Model Paper.js provides a Document Object Model (also called a Scene Graph) that is very easy to work with. Create a project and populate it with layers, groups, paths, rasters etc. Paths & Segments Paper.js makes is very easy to create paths and add segments to them. After adding, the segments can be easily inspected, manipulated, moved around, removed etc. Mouse Interaction Paper.js offers mouse handlers for the different actions you can perform with a mouse (or touch screen). You can use these handlers to produce different types of tools that have different ways of reacting to mouse interaction and movement. Keyboard Interaction Paper.js allows you to interact with the keyboard in two ways: You can either intercept key events and respond to these, or you can check the state of a given key at any moment, to see if it is pressed or not.
