Another really great example of using HTML5 canvas to accomplish things that used to require native applications is Sketchpad. And you can see the URL up there is mugtug.com/sketchpad. This is a drawing application created using HTML5 canvas, and I'm going to just do some stuff, like I can select the ellipse, and I can draw the ellipse on the canvas here, and I can use the brush and I can draw things. And you can see that I've got various settings in these windows down here. So, I can change all kinds of things. I can change colors.
I can even do advanced operations like cropping. So, this is a cropping tool. I am going to drag out a little cropping rectangle here and hit Enter, and you can see that by using the canvas, I'm able to grab subsets of images that have been drawn, draw them in to entirely new canvases. This is actually a really powerful application. You can see also up here I have other windows I can drag out. So this is a great example of something that used to require a native application to do and it's been implemented entirely using canvas and HTML5 technologies.
