You do realize that svg is a text (xml) format that is rendered on the fly by an svg processor, right? It''s not an binary image format. IE won''t render it without the adobe plugin and firefox finally got native support in 1.5. Also, that code that Chris posted wasn''t ruby... it''s html! Just put it in your rhtml template and it''ll pass right through. If you have dynamic information (like the file name) to put into the object tag, just break into ruby where you need to. For that matter, the other way to do this is to put the svg code right in your template. That was the whole intent of xhtml, is that we would be able to start mixing markup languages. Now, if you take that route, you''re probably in for some browser difficulties. On the other hand, using svg at all is still sketchy unless you know your audience will all have a browser capable of rendering it. Apologies if you already knew all about svg, but there are all levels of understanding on this list. b
I actually understand SVG very well and I realized it was straight html
(and I''ve tried html code that works under php (where it does use
"embed") - do you have a code example of what is working, maybe I am
missing syntax. Somehow the SVG code seems to be subsituting the SVG
object into the params. Here''s the error I get using Firefox 1.5 Rails
1.0 on Ubuntu with Webbrick:

I just copied Chris'' example into an *html* page, changed the name of svg file I had kicking around to match and opened it in Firefox.... no ruby or rails involved. So, that snippet is valid html syntax. I''m not clear on what you''re tyring to do... what produced that error? You should be able to just put the object tag in your rhtml. If you need to set the name of the svg at request time, you can just set an instance variable in the action and use that in the view. So, like this: in action: @svg_file = "/svg/test.svg" # or some logic to get file name ... in view: <object data="<%=@svg_file%>" type="image/svg+xml" height="64" width="64"/> ....... Hm, well crap... I tried throwing a little test together with the above and for some reason, firefox is opening the svg in another tab with a file:// url to my temp dir! Weird. Well, that''s not the problem you''re having... Try to get your rhtml working and maybe someone else here (Chris?) knows why Firefox treats the svg differently when it comes from a server... b jack wrote:> I actually understand SVG very well and I realized it was straight html > (and I''ve tried html code that works under php (where it does use > "embed") - do you have a code example of what is working, maybe I am > missing syntax.

okay - got SVG working (at least on Firefox so far) - combination of putting the closing embed tag (apparently wasn''t needed in html or php) and putting images into the .../public/images folder. Also note webbrick doesn''t seem to recognize the mime type but runs fine on apache2. <embed width=32 height=32 src="/images/quit.svg" type="image/svg+xml" /></embed> jack wrote:> Ben Munat wrote: > >> Hm, well crap...

Glad to hear you got it working Jack!! Um, though shouldn''t you remove the closing / from the opening tag if you have a closing tag? b jack wrote:> okay - got SVG working (at least on Firefox so far) - combination of > putting the closing embed tag (apparently wasn''t needed in html or php) > and putting images into the .../public/images folder.
