An interactive example of the HTML5 canvas ellipse() function

Written by Richard Heyes, on 2nd September 2013

Shows you an example of the new canvas v5 ellipse() function that is interactive (ie you can drag the ellipse around and resize it with your mouse).

Warning: This example currently (September 2013) only works on recent Google Chrome releases.

The ellipse() function was added in the canvas v5 edition of the spec and has now (2nd September 2013) been added to the Canary build of Google Chrome. This example will not work in browsers that do not support the ellipse() function.

All of the necessary code is within the window.onload function so it won't be hard to follow

[No canvas support]

The JavaScript code

Some sample code that generates the above ellipse is as follows. You can take this code and paste it into your application and if your browser has support for the ellipse() function you'll get an ellipse drawn on to your canvas.
