Succinctly and clearly written, this book examines dozens of real-world uses of the Canvas API, such as interactively drawing and manipulating shapes, saving and restoring the drawing surface to temporarily draw shapes and text, and implementing text controls. You’ll see how to keep your applications responsive with web workers when you filter images, how to implement smooth animations, and how to create layered, 3D scrolling backgrounds with parallax. In addition, you’ll see how to implement video games with extensive coverage of sprites, physics, collision detection, and the implementation of a game engine and an industrial-strength pinball game. The book concludes by showing you how to implement Canvas-based controls that you can use in any HTML5 application and how to use Canvas on mobile devices, including iOS5. This authoritative Canvas reference covers

The canvas element–using it with other HTML elements, handling events, printing a canvas, and using offscreen canvases
Shapes–drawing, dragging, erasing, and editing lines, arcs, circles, curves, and polygons; using shadows, gradients, and patterns
Text–drawing, positioning, setting font properties; building text controls
Images–drawing, scaling, clipping, processing, and animating
Animations–creating smooth, efficient, and portable animations
Sprites–implementing animated objects that have painters and behaviors
Physics–modeling physical systems (falling bodies, pendulums, and projectiles), and implementing tweening for nonlinear motion and animation
Collision detection–advanced techniques, clearly explained
Game development–all aspects of game development, such as time-based motion and high score support, implemented in a game engine
Custom controls–infrastructure for implementing custom controls; implementing progress bars, sliders, and an image panner
Mobile applications–fitting Canvas apps on a mobile screen, using media queries, handling touch events, and specifying iOS5 artifacts, such as app icons
Throughout the book, Geary discusses high-quality, reusable code to help professional developers learn everything they really need to know, with no unnecessary verbiage. All of the book’s code and live demonstrations of key techniques are available at CoreHTML5Canvas.com.
