The Hidden Power of Canvas

Dietrich Kappe, Thursday, November 13, 2008 @ 11:19 pm

Whenever we have Flash versus DHTML discussions in the office, someone usually utters the words "you probably can't do it, unless you used Canvas and some fancy JavaScript..."

At times that can seem like a cop out, an admission of defeat in the face of the Flash arsenal of graphic effects. Somtimes, like today, it seems more like a visionary declaration of the power of Canvas. Check out Steven Wittens' use of Canvas for projective texturing. Maybe there is a little bit more coolness left in these Ajax bones.

Whither Canvas?

This world is but canvas to our imaginations. -- Henry David Thoreau

First support for the WhatWG canvas element was announced by Apple in Safari, then it was included in Opera and Firefox. A little while back, Emil did a cool hack with VML to produce a subset of functionality as canvas for IE. There was a rumor that google would release this or some other code as its Canvas for IE solution, and it sort of has, landing with a thud over at sourceforge with a Google Code imprimature.

There have been no apparent developments since then. It doesn't seem to have been widely tested, is much slower than canvas in Firefox, and has enough differences and functional gaps to make integrating it with Javascript libraries that build on the canvas tag somewhat difficult.

There don't appear to be any plans to support canvas in IE7, but things can change quickly over there, apparently. So, do you support canvas in IE with an impressive piece of late night hackery like Emil's work, or is support for canvas just not there yet -- a really nice feature not supported effectively for 90% of the web browsing public?

I'm leaning toward the latter. What do you think?
