Image processing with HTML canvas

JsPlumb and HTML canvas go back a long way, right to the start, in fact. We got our initial inspiration from Yahoo Pipes, making use of the fact that you can draw bezier curves into canvas elements. Over time the canvas element has become more and more powerful, and it can now do some pretty fancy image processing tasks. For our image processor starter app we wrote a bunch of methods to perform various filtering and transformation operations, collating them from various corners of the internet, and so we thought maybe it would be useful for others if we documented them.

We've released these functions on NPM as an MIT licensed library - take a look at the project page on Github for installation instructions.
