</h1>
<p>The QtOpenVG module is a plugin that provides support for OpenVG painting. <a href="#details">More...</a></p>
<a name="details"></a>
<h2>Detailed Description</h2>
<p>OpenVG is a standard API from the <a href="http://www.khronos.org/openvg">Khronos Group</a> for accelerated 2D vector graphics that is appearing in an increasing number of embedded devices.</p>
<p>OpenVG support can be enabled by passing the <tt>-openvg</tt> option to configure. It is assumed that the following qmake variables are set to appropriate values in the qmake.conf file for your platform:</p>
<ul>
<li><a href="qmake-variable-reference.html#qmake-incdir-openvg">QMAKE_INCDIR_OPENVG</a></li>
<li><a href="qmake-variable-reference.html#qmake-libdir-openvg">QMAKE_LIBDIR_OPENVG</a></li>
<li><a href="qmake-variable-reference.html#qmake-libs-openvg">QMAKE_LIBS_OPENVG</a></li>
</ul>
<p>Most OpenVG implementations are based on EGL, so the following variables may also need to be set:</p>
<ul>
<li><a href="qmake-variable-reference.html#qmake-incdir-egl">QMAKE_INCDIR_EGL</a></li>
<li><a href="qmake-variable-reference.html#qmake-libdir-egl">QMAKE_LIBDIR_EGL</a></li>
<li><a href="qmake-variable-reference.html#qmake-libs-egl">QMAKE_LIBS_EGL</a></li>
</ul>
<p>See <a href="qmake-variable-reference.html">qmake Variable Reference</a> for more information on these variables.</p>
<p>Two kinds of OpenVG engines are currently supported: EGL based, and engines built on top of OpenGL such as <a href="http://sourceforge.net/projects/shivavg">ShivaVG</a>. EGL based engines are preferred.</p>
<p>Once the graphics system plugin has been built and installed, applications can be run as follows to use the plugin:</p>
<pre> app -graphicssystem OpenVG</pre>
<p>If ShivaVG is being used, then substitute <tt>ShivaVG</tt> instead of <tt>OpenVG</tt> in the line above.</p>
