<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<p>Classes that provide support for vector graphics painting. </p>
<p>Wt provides a vector graphics painting system, which depending on the browser support, uses one of four different methods to paint the graphics (inline SVG, inline VML, HTML 5 <canvas> or a raster image). Vector graphics has as benefit a lower bandwidth usage compared to raster images, indepedent of the image size. To use the paint system, you need to specialize <a class="el" href="classWt_1_1WPaintedWidget.html" title="A widget that is painted using vector graphics.">WPaintedWidget</a> and use a <a class="el" href="classWt_1_1WPainter.html" title="Vector graphics painting class.">WPainter</a> to paint the contents of the widget inside its <a class="el" href="classWt_1_1WPaintedWidget.html#ad8ce22eff41754c8616f45851f57fb1a" title="Paints the widget.">WPaintedWidget::paintEvent()</a>.</p>
<p>In addition, a PDF backend is included in the library, which can be used to make a PDF version of a painting, or to embed a painting in a PDF document.</p>
<p>To use inline SVG, you need to enable xhtml support in your configuration file by enabling send-xhtml-mimetype, see <a class="el" href="overview.html#config_general">10.2 General application settings (wt_config.xml)</a>. </p>
