HTML 5 Canvas

Before the web, software developers implemented what we now refer to as desktop applications, using powerful graphics APIs that gave them the ability to program pretty much anything they could imagine. Then along came browsers with virtually no standard graphics support at all. Enter boring web applications, and dull work for developers.

But now, with HTML5 Canvas, developers have a powerful graphics API that lets them develop mind-blowing applications. Now you can implement desktop-like applications that run in a browser. Tonight, we'll see how.

This talk is a demo-fueled, fast-paced introduction to HTML5 Canvas. You'll get an overview of the Canvas API, and see how you can use it to draw, manipulate images, and implement sprite-based animation. You will get a feel for what you can do with this powerful API, and you'll get a basic understanding of how to harness that power.

David Geary

David is the founder of Clarity Training, where he teaches software developers to implement web applications using HTML5, JavaServer Faces, and Google Web Toolkit.

A prominent author, speaker, and consultant, David is the author of 6 Java books, four of which are best-sellers in their respective categories, including one of the best-selling Java book series of all time, Graphic Java. David is currently writing Core HTML5 for Prentice-Hall.

David has worked on several open-source projects, and was the second committer for the venerable Struts web application framework. David served on Sun expert groups, helping to define technologies such as the JSP tag library, and JavaServer Faces. David is also a prolific speaker who has spoken at hundreds of conferences, and is a three-time JavaOne Rock Star.

Intro to Inkscape

We have the GIMP for photo manipulation and web images, Blender for 3D graphics. But what do you do when you want an open source tool make logos or illustrations? Something that's like Adobe Illustrator, that's what!

Inkscape started as a fork of the sodipodi project aimed at supporting the full Scalable Vector Graphic specification. It's grown into a vibrant community of graphics artists and developers for vector graphics. Vector graphics are fully scalable mathematically derived images, ideal for logos and diagrams.

Ryan Freckleton

Ryan is a software application development engineer at MITRE Corporation. He's been an open source enthusiast for 13 years, and using Inkscape on and off for 5.

When not writing software, he enjoys flying kites, hiking and cooking.
