Scalable Vector Graphics (SVG) is a computer language to describe two dimensional images. SVG is based on XML and created by the World Wide Web Consortium (W3C). The language describes pictures by their elements. So you can zoom in and it stays clear without big pixels.

History[change | edit source]

The W3C published SVG in September 2001. Most browsers can show these graphics but Internet Explorer cannot. It needs a plugin to show them.

The normal Filename extension is .svg and the MIME-Type is image/svg+xml.

Structure[change | edit source]

SVG uses Extensible Markup Language (XML). So it has a definition of the document type.

 <?xml version="1.0" encoding="utf-8"?>
 
 <svg xmlns="http://www.w3.org/2000/svg"
  xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ev="http://www.w3.org/2001/xml-events"
  version="1.1" baseProfile="full"
  width="800mm" height="600mm">
