<h2>Detailed Description</h2>
<p>The Q3Picture class is a paint device that records and replays <a href="q3painter.html">Q3Painter</a> commands.</p>
<p>Q3Picture can also read and write SVG (Scalable Vector Graphics) files, a <a href="http://www.w3.org/Graphics/SVG/">W3C</a> XML format. Note that when using the <a href="q3picture.html#load">load</a>() and <a href="q3picture.html#save">save</a>() functions to read and write SVG files, the format must be specified.</p>
<p>See also <a href="qpicture.html">QPicture</a>.</p>

<h2>Member Function Documentation</h2>
<a name="//apple_ref/cpp/instm/Q3Picture/Q3Picture"></a>
<h3 class="fn"><a name="Q3Picture"></a>Q3Picture::Q3Picture ()</h3>
<p>Constructs a <a href="q3picture.html" class="compat">Q3Picture</a>.</p>
<h3 class="fn"><a name="Q3Picture-2"></a>Q3Picture::Q3Picture ( const <a href="qpicture.html">QPicture</a> & <i>other</i> )</h3>
<p>Constructs a copy of <i>other</i>.</p>
<a name="//apple_ref/cpp/instm/Q3Picture/load"></a>
<h3 class="fn"><a name="load"></a>bool Q3Picture::load ( <a href="qiodevice.html">QIODevice</a> * <i>device</i>, const char * <i>format</i> = 0 )</h3>
<p>Loads the picture in the specified <i>format</i> from the given <i>device</i>. Returns true if the file is loaded successfully; otherwise returns false.</p>
<p>Note that when using the load() function to read SVG files, the format must be specified. For example:</p>
<pre> Q3Picture picture;
picture.load("drawing.svg", SVG);</pre>
<p>See also <a href="q3picture.html#save">save</a>().</p>
<h3 class="fn"><a name="load-2"></a>bool Q3Picture::load ( const <a href="qstring.html">QString</a> & <i>fileName</i>, const char * <i>format</i> = 0 )</h3>
<p>This is an overloaded function.</p>
<p>Loads the picture in the specified <i>format</i> from a file with the given <i>fileName</i>. Returns true if the file is loaded successfully; otherwise returns false.</p>
<a name="//apple_ref/cpp/instm/Q3Picture/save"></a>
<h3 class="fn"><a name="save"></a>bool Q3Picture::save ( <a href="qiodevice.html">QIODevice</a> * <i>device</i>, const char * <i>format</i> = 0 )</h3>
<p>Saves the picture in the specified <i>format</i> to the given <i>device</i>. Returns true if the save is successful. Returns false if, for example, the picture is still being painted, i.e., <a href="qpainter.html#end">QPainter::end</a>() has not yet been called.</p>
<p>Note that when using the save() function to save SVG files, the format must be specified. For example:</p>
<pre> Q3Picture picture;
QPainter painter;
painter.begin(&picture); <span class="comment">// paint in picture</span>
...
painter.end(); <span class="comment">// painting done</span>
picture.save("drawing.svg", SVG); <span class="comment">// save picture</span></pre>
<p>See also <a href="q3picture.html#load">load</a>().</p>
<h3 class="fn"><a name="save-2"></a>bool Q3Picture::save ( const <a href="qstring.html">QString</a> & <i>fileName</i>, const char * <i>format</i> = 0 )</h3>
<p>This is an overloaded function.</p>
<p>Saves the picture in the specified <i>format</i> to the file with the given <i>fileName</i>.</p>
