<p class="intro">SVG is a language for describing 2D-graphics and graphical
applications in XML.</p>
<hr />
<h2>What you should already know</h2>
<p>Before you continue, you should have some basic understanding of the following:</p>
<ul>
<li>HTML </li>
<li>Basic XML</li>
</ul>
<p>If you want to study these subjects first, find the tutorials on our
<a href="../default.asp">Home page</a>.</p>
<hr />
<h2>What is SVG?</h2>
<ul>
<li>SVG stands for <b>S</b>calable <b>V</b>ector <b>G</b>raphics</li>
<li>SVG is used to define vector-based graphics for the Web</li>
<li>SVG defines the graphics in XML format</li>
<li>SVG graphics do NOT lose any quality if they are zoomed or resized</li>
<li>Every element and every attribute in SVG files can be animated</li>
<li>SVG is a World Wide Web Consortium (W3C) recommendation</li>
<li>SVG integrates with other W3C standards such as the DOM and XSL</li>
</ul>
<hr />
<h2>SVG History & Advantages</h2>
<p>SVG 1.1 became a W3C Recommendation in January 2003.</p>
<p>Sun Microsystems, Adobe, Apple, IBM, and Kodak are some of the
organizations that have been involved in defining SVG.</p>
<p>Advantages of using SVG over other image formats (like JPEG
and GIF) are:</p>
<ul>
<li>SVG files can be read and modified by a large range of tools (e.g. notepad)</li>
<li>SVG files are smaller and more compressible than JPEG and GIF images</li>
<li>SVG images are scalable</li>
<li>SVG images can be printed with high quality at any resolution</li>
<li>SVG images are zoomable. Any part of the image can be zoomed without degradation</li>
<li>Text in SVG is selectable and searchable (excellent for making maps)</li>
<li>SVG works with Java technology</li>
<li>SVG is an open standard</li>
<li>SVG files are pure XML</li>
</ul>
<p>The main competitor to SVG is Flash.</p>
<p>The biggest advantage SVG has over Flash is the compliance with other standards
(e.g. XSL and the DOM). Flash relies on proprietary technology that is not
open source.</p>
<p>A drawback of SVG at the moment is that not all browsers support it. Mozilla
browsers, Firefox, and Opera support SVG, and Microsoft plan to support SVG.</p>
<p>The number of SVG editors are growing, and Adobe GoLive 5 supports SVG.</p>
<p><a target="_blank" href="../../www.svgi.org/default.htm">Look at a directory of SVG
enabled software and services</a></p>
<p>To view SVG files today, you may have to install a plug-in such as the Adobe SVG Viewer.</p>
<hr />
<h2>Viewing SVG Files</h2>
<p>If your browser does not support SVG files, you will need to download an SVG
viewer to view SVG files.</p>
<p><b>Note:</b> Firefox 1.5 and Opera 9 have native SVG support. If you are using
