<p>To import the module use, for example, the following statement:</p>
<pre>from PyQt4 import QtSvg</pre>
<p>Scalable Vector Graphics (SVG) is a language for describing two-dimensional graphics and graphical applications in XML. SVG 1.1 is a W3C Recommendation and forms the core of the current SVG developments in Qt. SVG 1.2 is the specification currently being developed by the <a href="http://www.w3.org/Graphics/SVG/">SVG Working Group</a>, and it is <a href="http://www.w3.org/TR/SVG12/">available in draft form</a>. The <a href="http://www.w3.org/TR/SVGMobile/">Mobile SVG Profiles</a> (SVG Basic and SVG Tiny) are aimed at resource-limited devices and are part of the 3GPP platform for third generation mobile phones. You can read more about SVG at <a href="http://www.w3.org/Graphics/SVG/About.html">About SVG</a>.</p>

<h3>SVG Support</h3>
<p>Qt supports the <a href="http://www.w3.org/Graphics/SVG/feature/1.2/#SVG-static">static features</a> of <a href="http://www.w3.org/TR/SVGMobile12/">SVG 1.2 Tiny</a>. ECMA scripts and DOM manipulation are currently not supported.</p>
<a name="configuring-the-build-process" />
<h3>Rendering SVG files</h3>
<p>The easiest way to render SVG files is to construct a <a href="qsvgwidget.html">QSvgWidget</a> and load an SVG file using one of the <a href="qsvgwidget.html#load">QSvgWidget.load</a>() functions.</p>
<p><a href="qsvgrenderer.html">QSvgRenderer</a> is the class responsible for rendering SVG files for <a href="qsvgwidget.html">QSvgWidget</a>, and it can be used directly to provide SVG support for custom widgets. To load an SVG file, construct a <a href="qsvgrenderer.html">QSvgRenderer</a> with a file name or the contents of a file, or call <a href="qsvgrenderer.html#load">QSvgRenderer.load</a>() on an existing renderer. If the SVG file has been loaded successfully the <a href="qsvgrenderer.html#isValid">QSvgRenderer.isValid</a>() will return true.</p>
<p>Once you have loaded the SVG file successfully, you can render it with the <a href="qsvgrenderer.html#render">QSvgRenderer.render</a>() function. Note that this scheme allows you to render SVG files on all paint devices supported by Qt, including <a href="qwidget.html">QWidget</a>, <a href="qglwidget.html">QGLWidget</a>, and <a href="qimage.html">QImage</a>. See the <a href="painting-svgviewer.html">SVG Viewer</a> example for more details.</p>
