Is an XML based 2D vector graphics format.
One of the most common problems is the wrong mime type for the SVG graphics. In this case the image is not displayed correctly on some browsers like on the iPhone/iPad. You need to make sure that your webserver is serving the file with the type image/svg+xml.
If you are using Apache as your web server you can add the following line to your .htaccess file to make sure that the correct mime type is used
AddType image/svg+xml .svg
If you are using Microsofts IIS you need to add the following to your web.config file:
<configuration> <system.webServer> <staticContent> <mimeMap fileExtension=".svg" mimeType="image/svg+xml" /> </staticContent> </system.webServer> </configuration>
To test the mime type you can use for example this website or the command line tool curl with following line:
curl -I http://example.com/your.svg
