Canvas Pocket Reference: Scripted Graphics for HTML5 (Pocket Reference (O'Reilly)) ReviewSummary: The book provides examples to explain feature after feature of canvas, carefully mentioning the concepts behind the feature being explained (strokes, gradients, transparency, text, shadows, etc). This book will explain how things are done and after that, you'll be able to grab sample code from the web and actually be able to customize it to what you need.
The book contains two chapters that are completely different of each other. The first chapter explains how things work in canvas. For example, whatever you draw uses a style that is defined separately from the drawing code, similar to the separation of content and presentation in HTML/CSS. The way you draw graphics, fill them, color them, etc is different than traditional environments such as Java graphics. At the end of the first chapter, you'll know what can be done using canvas and how.
The second chapter is a reference of the canvas methods, which will be the details needed once you're actually coding. Fortunately, there are not that many methods in canvas. If unfamiliar with pocket reference books from O'Reilly, they are small, you can carry it in the back pocket of your jeans. If you do not wear jeans or shorts at work, then you may not be the intended audience for this book. I needed a book that explains how to use bitmap images and do image processing in them. The few pages in the book on those topics made the book worthwhile. I'm looking forward to see the Web when most sites use canvas (instead of Flash and the like) for simple graphic animations or just improved user interfaces. (Disclaimer: I was provided a hard-copy of the book from O'Reilly for review and returned it back).
Canvas Pocket Reference: Scripted Graphics for HTML5 (Pocket Reference (O'Reilly)) Overview
The Canvas element is a revolutionary feature of HTML5 that enables powerful graphics for rich Internet applications, and this pocket reference provides the essentials you need to put this element to work. If you have working knowledge of JavaScript, this book will help you create detailed, interactive, and animated graphics -- from charts to animations to video games -- whether you're a web designer or a programmer interested in graphics.

Canvas Pocket Reference provides both a tutorial that covers all of the element's features with plenty of examples and a definitive reference to each of the Canvas-related classes, methods, and properties.

You'll learn how to:

Draw lines, polygons, and curves
Apply colors, gradients, patterns, and transparency
Use transformations to smoothly rotate and resize drawings
Work with text in a graphic environment
Apply shadows to create a sense of depth
Incorporate bitmapped images into vector graphics
Perform image processing operations in JavaScript

Foundation HTML5 Canvas: For Games and Entertainment ReviewThis book has been instrumental in pushing my understanding of how to draw and animate using the Canvas API but also introducing me to physics and the mathematics involved with creating games. While those concepts can be complex the author does a good job of breaking them down and explaining them clearly.
If you want to develop a good understanding of how to use HTML5 Canvas and how to write games within Canvas this is the book for you. Yes it is a foundation, it gives you a foundation in this new technology and gives you enough exposure to the core concepts to competently go out and start making things yourself. There is always more that they could have demonstrated and as pointed out several times in the book if you want to delve right into the guts of game physics and the like there are entire books written on that one aspect. The author has written a great book which has been invaluable to me and I would highly recommend it.Foundation HTML5 Canvas: For Games and Entertainment OverviewFoundation HTML5 Canvas: For Games and Entertainment teaches you how to make exciting interactive games and applications using HTML5 canvas.

Introducing HTML5 (Voices That Matter) ReviewHTML5 is creating more and more a name for itself in our industry, but while it excites those on the cutting edge of web technology, many are left feeling uncertain about it. Its ongoing development has been victim of politics, fragmentation and more, leaving few to have a good grasp of its current status. However, a lot of the technologies that make up HTML5 (and more) have become mature, even implemented across all the latest browsers--but did you know that? If you've kept an arms length to everything going on with HTML5, now is the time to dive into its waters and explore.
Fortunately, you don't have to do it all by yourself: just get Introducing HTML5, written by Bruce Lawson (Opera) and Remy Sharp (Left Logic).
Exactly as its name implies, Introducing HTML5 is an introduction to all the new semantics and application-oriented technologies that make up the HTML5 spec. You don't have to be a web development expert to read this, but you'll come out closer to one when you've finished. All you need is a good grasp of web standards-based techniques, e.g. semantic markup; separation of structure, presentation and behavior; and accessibility. Bruce and Remy will teach you everything you need to know to bring your skill set to the next level.
Starting out light, Introducing HTML5 first teaches you the most important new HTML5 elements and their semantic purposes, which is especially helpful if, like me, you kept an eye on these since the early stages of HTML5, but got confused as their meanings were changed or redefined.
The book continues with the new HTML5 Forms, serving as a nice segue into the more JavaScript-reliant HTML5 Audio and Video, before it hunkers down on the real new technologies in HTML5, starting with Canvas and going all the way to the Messages, Web Workers and Web Sockets APIs.
Throughout the book, Bruce and Remy do a great job at not just introducing the new technologies, but informing you exactly of what does and doesn't work in which browsers. Even the latest releases of browsers have some glaring bugs here and there, but where fixes are available, they are presented, and where not, workarounds explained. As a result, Introducing HTML5 is a tremendously practical book, going well beyond a surface-level introduction and straight-up teaching you how to wield these new technologies today.
One thing I am personally very happy about is how the book teaches you how to implement things in an accessible way (via ARIA or otherwise), making sure that visitors to your sites aren't left out. HTML5 is exciting, but our excitement shouldn't come at the cost of accessibility--and following Bruce and Remy's advice, it won't.
The compact but dense information in Introducing HTML5 means that in just an afternoon or two, you'll find yourself brimming with new knowledge, excitement and ideas for making your websites or web applications richer, more exciting and more powerful. All in all, a highly recommended read.Introducing HTML5 (Voices That Matter) OverviewSuddenly, everyone's talking about HTML5, and ready or not, you need to get acquainted with this powerful new development in web and application design. Some of its new features are already being implemented by existing browsers, and much more is around the corner.Written by developers who have been using the new language for the past year in their work, this book shows you how to start adapting the language now to realize its benefits on today's browsers. Rather than being just an academic investigation, it concentrates on the practical—the problems HTML5 can solve for you right away. By following the book's hands-on HTML5 code examples you'll learn:
new semantics and structures to help your site become richer and more accessible

how to apply the most important JavaScript APIs that are already implemented

the uses of native multimedia for video and audio

techniques for drawing lines, fills, gradients, images and text with canvas

how to build more intelligent web forms

implementation of new storage options and web databases

how geolocation works with HTML5 in both web and mobile applications
