painty – A simple HTML5 web app for the iPad

As you may know I have been mucking around with HTML5’s canvas element lately. Here is an evolution of the paint mixing example I showed a couple posts back. I decided to turn it into a simple iPad web app. Check out the video below and visit the following URL on an iPad to try it out. I also plan to make it multitouch in the not too distant future!

Javascript and Canvas wet paint mixing

Here is an experiment I did to learn how the HTML5 Canvas tag works. I wanted to know how to manipulate pixels so I attempted to port my AS3 paint mixing to Javascript. I was surprised by the performance although it doesn’t seem to be as fast as the Flash version, and it is definitely a lot more work getting and setting pixels with Javascript and Canvas. Check out the demo below. The brush will lag at higher drawing speeds when the size is large. But it if you don’t draw too fast it works pretty well. So far it seems to work best in Safari.

Supported browsers:

  • Chrome (Only tested in Chrome 12)
  • Safari (Only tested in Safari 5)
  • IE9

Note: Doesn’t work in Firefox and haven’t tried Opera
