SoSLUG's Alan Campion, has done a wonderful job of teaching us all about things we can do using the new HTML5 canvas tag. This is designed as a supplementary article to his efforts, to show some things you can do with the HTML5 canvas tag to save/serialize it's data for use elsewhere.

Canvas element - adding text

A previous example used the following three diagrams as part of a maths refresher. The original diagrams were (of course!) drawn using the canvas element. By placing the mouse over any canvas element on any HTML page, and right clicking on it, you can then save the resulting drawing just as you would for any other image.
