Displaying SVG images

rubyonrails-talk

I cannot get SVG to display under Rails even using the normal html embed command. I suspect it might have to do with a mime setting but not sure. The Scruff SVG graph library is written in Ruby so it obviously can be done. Any help? thks.

The real question is more like: "Does my browser understand how to render SVG?"

Or perhaps: "How can I convert an SVG into a format that browser X can display?"

Do you need to visit the Adobe SVG Viewer download page?   http://www.adobe.com/svg/viewer/install/main.html

no, that isn't the question - I have svg images displaying fine on our website html pages with Firefox - yet when trying to use the same html embed commands inside a Rails app, the images don't want to display. Maybe Rails doesnt' see them under public/images or doesn't like the mime type.

This seems incredibly familiar. I had an issue where a flash embed wasn't working, so I had to use send_file and explicitly set the mime type. What server are you using?

I have the exact same problem: I cannot serve (correctly embeded) svg files from a rails project (instiki) using WEBrick as webserver. My browser (firefox 2.0.0.1) asks me where to save the .svg file, instead of showing it.

I did some testing, and using WEBrick directly (without rails around it) DOES work correctly. I've been messing around in several places, adding the mime-type "svg" => "image/svg+xml" in /usr/lib/ruby/1.8/webrick/httputils.rb, adding it manually in script/server to the OPTIONS variable, but nothing seems to work...

This is the working WEBrick code (with the svg mime-type still added in my /usr/lib/ruby dir): require 'webrick' include WEBrick s = HTTPServer.new(   :Port => 2000,   :DocumentRoot => Dir::pwd + "/htdocs" ) trap("INT"){ s.shutdown } s.start

using webbrick. How did you specifically use send_file and where did you set mime type to get it to work ? thks
