create SVG drawings.</p>
<p>This paint device represents a Scalable Vector Graphics (SVG)
drawing. Like <a href="qprinter.html">QPrinter</a>, it is designed
as a write-only device that generates output in a specific
format.</p>
<p>To write an SVG file, you first need to configure the output by
setting the <a href="qsvggenerator.html#fileName-prop">fileName</a>
or <a href="qsvggenerator.html#outputDevice-prop">outputDevice</a>
properties. It is usually necessary to specify the size of the
drawing by setting the <a href="qsvggenerator.html#size-prop">size</a> property, and in some cases
where the drawing will be included in another, the <a href="qsvggenerator.html#viewBox-prop">viewBox</a> property also needs
to be set.</p>
<pre class="cpp">
<span class="type">QSvgGenerator</span> generator;
generator<span class="operator">.</span>setFileName(path);
generator<span class="operator">.</span>setSize(<span class="type"><a href="qsize.html">QSize</a></span>(<span class="number">200</span><span class="operator">,</span> <span class="number">200</span>));
generator<span class="operator">.</span>setViewBox(<span class="type"><a href="qrect.html">QRect</a></span>(<span class="number">0</span><span class="operator">,</span> <span class="number">0</span><span class="operator">,</span> <span class="number">200</span><span class="operator">,</span> <span class="number">200</span>));
generator<span class="operator">.</span>setTitle(tr(<span class="string">"SVG Generator Example Drawing"</span>));
generator<span class="operator">.</span>setDescription(tr(<span class="string">"An SVG drawing created by the SVG Generator "</span>
<span class="string">"Example provided with Qt."</span>));
</pre>
<p>Other meta-data can be specified by setting the <i>title</i>,
<i>description</i> and <i>resolution</i> properties.</p>
<p>As with other <a href="qpaintdevice.html">QPaintDevice</a>
subclasses, a <a href="qpainter.html">QPainter</a> object is used
to paint onto an instance of this class:</p>
<pre class="cpp">
<span class="type"><a href="qpainter.html">QPainter</a></span> painter;
painter<span class="operator">.</span>begin(<span class="operator">&</span>generator);
...
painter<span class="operator">.</span>end();
</pre>
<p>Painting is performed in the same way as for any other paint
device. However, it is necessary to use the <a href="qpainter.html#begin">QPainter.begin</a>() and <a href="qpainter.html#end">end()</a> to explicitly begin and end painting
on the device.</p>
<p>The <a href="painting-svggenerator.html">SVG Generator
Example</a> shows how the same painting commands can be used for
painting a widget and writing an SVG file.</p>
