HTML5 Canvas Cookbook

Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Define the Events constructor."

A block of code is set as follows:

var Events = function(canvasId){
    this.canvas = document.getElementById(canvasId);
    this.context = this.canvas.getContext("2d");
    this.stage = undefined;
    this.listening = false;
};

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

var Events = function(canvasId){
    this.canvas = document.getElementById(canvasId);
    this.context = this.canvas.getContext("2d"); this.stage = undefined; ...
