The moment people start using getImageData() as storage mechanism (which they will if browsers do not fix their data: image origin stuff) you'll have a problem with this if the application is accessed through different devices that have different ratios. I suspect though that given that Firefox has a 1:1 ratio sites will simply rely on that... -- Anne van Kesteren <http://annevankesteren.nl/> <http://www.opera.com/>
