Capture a Signature with jQuery and HTML 5

In this series you’ll learn how to add a signature field to your website that allows a user to write their signature on an HTML 5 canvas element. You’ll capture the signature and save it on the server and also learn how to regenerate the signature to display it back to the user at a later date. This technique is cross browser friendly and works in IE7, 8, 9, Chrome, Firefox and Safari. It will also work on most mobile device touch screens.

This session will describe how to create linkers and explains some of the linkers we’ve created, including a linker that turns a GWT module into an HTML5 Web Worker and one that generates an HTML App Cache manifest automatically.
