(Ca)nvas (Man)ipulation is javascript library for manipulating images using the HTML5 canvas.

The main focus of CamanJS is manipulating images using the HTML5 canvas and Javascript. It's a combination of a simple-to-use interface with advanced and efficient image/canvas editing techniques. It is also completely library independent and can be safely used next to jQuery, YUI, Scriptaculous, MooTools, etc.

CamanJS is very easy to extend with new filters and plugins, and it comes with a wide array of image editing functionality, which is only growing as the community makes more plugins. All features that are not a part of the core CamanJS library are in a separate plugins repository.

For more information, I highly recommend taking a look at the official website where there is more comprehensive documentation and interactive demos. You can also read the wiki for some basic information about the project and how to use it.

CamanJS is written in Coffeescript as of version 3.0. It works both in-browser and in NodeJS.
