HTML5 Canvas Cheat Sheet

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.

Prototype Cheat Sheet

  • Modules are sorted in a somewhat logical order – those commonly used are mostly in the left/center area, while deprecated/utility methods are all the way to the right
  • Method can be recognized by parentheses following it (anything that doesn’t have ones is a property)
  • Deprecated items are marked red and have NO parentheses/arguments specified
  • Prototype extends quite few native objects’ prototypes with a set of convenient methods. In such cases there’s an explicit note about it next to a module name – i.g. stripScripts() method from “String (String.prototype)” can be called as 'foo'.stripScripts()
  • When a module is also a class, there’s a “(constructor)” note next to it – i.g. “Hash (constructor)” means that it should be called as new Hash()
  • There are few bonus items (such as those from Prototype.Browser) which are not yet included in documentation
