# re: SVG in IE9 Roadmap
Tuesday, March 30, 2010 11:20 AM by Francis Hemsher

Now that Internet Explorer has embraced SVG, I think it is time to
look at IE8 users and their transition into IE9. This is a suggestion
that should make the process of viewing SVG seamless in both browser

The key is the <EMBED> element. This provides very solid svg viewing
in IE8 if the Adobe SVG Viewer ActiveX is installed in the user's

The <EMBED> call in IE9 could include a default flag that used the
Adobe ActiveX if it were available. This would then allow IE9 to view
the many 1000's of svg apps created by svg developers during the past
10 years.

Furthermore, in the best of SVG worlds, the Adobe ActiveX could be a
resident ActiveX in IE9.

The IE9 Roadmap does state that SVG will be available for the <embed>.

"In future updates, the IE9 Platform Preview will support:
Methods of embedding: <embed>, <iframe>, <img>, css image, .svgz"

If this suggestion is accepted, then those who also want to take
advantage of ASV's resident Animation, SMIL, and Filters could do so
in IE9.
