How can I use the HTML5 canvas element in IE

Question

I am trying to use the HTML5 canvas element to draw some arcs and circles - this works perfectly in FF but IE8 does not seem to support it   Now  there exist Javascript libraries which seem to make IE8 work well with Canvas  An example can be found here   I have read their entire source but I cannot understand how they are making Canvas work with IE8  Can somebody please throw some light on the method used

If you need to use IE8  you can try this JavaScript library for vector graphics  It is like solving the  canvas  and  SVG  incompatibilities of IE8 at the same time   Rapha  l  I have just try it in a fast example and it works correctly  I don t know how legible is the source code but I hope it helps you  As they said in its site  the library is compatible with very old explorers      Rapha  l currently supports Firefox 3 0   Safari 3 0   Chrome 5 0   Opera 9 5  and Internet Explorer 6 0

I just used flashcanvas  and I got that working  If you encounter problems  just make sure to read the caveats and whatnot  Particularly  if you create canvas elements dynamically  you need to initialize them explicitly   if  typeof FlashCanvas     undefined         FlashCanvas initElement canvas

Currently  ExplorerCanvas is the only option to emulate HTML5 canvas for IE6  7  and 8   You re also right about its performance  which is pretty poor     I found a particle simulatior that benchmarks the difference between true HTML5 canvas handling in Google Chrome  Safari  and Firefox  vs ExplorerCanvas in IE   The results show that the major browsers that do support the canvas tag run about 20 to 30 times faster than the emulated HTML5 in IE with ExplorerCanvas   I doubt that anyone will go through the effort of creating an alternative because 1  excanvas js is about as cleanly coded as it gets and 2  when IE9 is released all of the major browsers will finally support the canvas object   Hopefully  We ll get IE9 within a year  Eric   www webkrunk com

The page is using excanvas - a JS library that simulates the canvas element using IE s VML renderer   Note that in Internet Explorer 9  the canvas tag is supported natively  See MSDN docs for details

You could use the newly released Chrome Frame plugin for IE  but it requires that the HTML 5 website includes the special meta tag that enables the plugin   http   code google com chrome chromeframe   Chrome Frame seems to use Explore Canvas  excanvas js
