I actually sent an email to the author when this article came out (a couple days ago). He uses the term "SVG" generically where he should use the term "vector graphics". After a bit of email discussion he said he would contact his editor to correct some of the erroneous statements like: "Nearly all the latest technologies support SVG today, such as Microsoft's Silverlight, Sun®'s JavaFX, OpenLazlo, and Adobe Flex (or Flash)" Regards, Jeff On Thu, Mar 19, 2009 at 11:34 AM, Ruud Steltenpool <svg@steltenpower.com> wrote: > Yeah, it's kind of backwards > > > Porter, David A wrote: >> >> This article sounded promising, but my hopes were dashed after reading >> it, it's concerning yet-another "vector" description language present in >> the <Canvas> tag, e.g. namespace >> xmlns:mx="http://www.adobe.com/2006/mxml" implemented in Flex. >> >> The article did mention that: "The upcoming version of Flex, Flex 4.0, is >> also going to provide >> framework-level support for sophisticated SVG drawings."
