The alternative (a css property or whatever) would allow a developer to use a single API, but tell the browser that they were aware that there may not be a 1:1 ratio between the requested region and the amount of data returned -- effectively it would be a flag to say "hey i actually do know the spec, and am not blindly expecting this to work on everyone else's computer just because it works on mine" </div> </div><font color="#888888"></font></div></div></blockquote><div><br>OK, but I wouldn't use a property, I'd use a content attribute, because you want to be able to work with <canvas> elements that aren't in a document and thus don't really have style.</div></div></blockquote><div>Ah good point, i had not considered that. I agree, an attribute would probably be better (although the concept itself is still icky)</div><div><br></div><blockquote type="cite">Rob</blockquote><br></div>--Oliver<br></body></html>
