Canvas Cheat Sheet
Jacob Seidelin has created this great cheat sheet for experienced users of the canvas element.
The Canvas Cheat Sheet is a really useful document
The information is pretty much just a copy of what is found in the WHATWG specs, just condensed and hopefully a bit easier to read. There are virtually no explanations, however, and no examples other than some graphics for compositing values and a few other things (the appearance of which is very much inspired by those found in Mozilla’s examples). So, it’s basically just a listing of the attributes and methods of the canvas element and the 2d drawing context.
He’s made the file available as both a PDF document and a PNG file.
