HTML Canvas Demo

Description:

This is a simple web app for drawing boxes on a canvas object. It allows for changing the stroke and fill color and size of the boxes and calculates the box area and perimeter on the fly. It can also undo up to 10 times. It includes mouse and touch events and will therefore work on tablet devices (though multi-touch is not utilized).
This simple web app could be the basis for a more robust web based drawing program. All the JavaScript is well documented.

Notes:

The page layout is not responsive, so a minimum screen size of 1024 x 768 is recommended.
