<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="invert"></a>QMatrix QMatrix::invert ( bool * <i>invertible</i> = 0 ) const</h3>
<p>Returns an inverted copy of this matrix.</p>
<p>Use the <a href="qmatrix.html#inverted">inverted</a>() function instead.</p>
<h3 class="fn"><a name="map-2"></a><a href="qrect.html">QRect</a> QMatrix::map ( const <a href="qrect.html">QRect</a> & <i>rect</i> ) const</h3>
<p>This is an overloaded member function, provided for convenience.</p>
<p>Creates and returns a <a href="qrect.html">QRect</a> object that is a copy of the given rectangle, mapped into the coordinate system defined by this matrix.</p>
<p>Use the <a href="qmatrix.html#mapRect">mapRect</a>() function instead.</p>
<h3 class="fn"><a name="mapToRegion"></a><a href="qregion.html">QRegion</a> QMatrix::mapToRegion ( const <a href="qrect.html">QRect</a> & <i>rectangle</i> ) const</h3>
<p>Returns the transformed rectangle <i>rectangle</i> as a <a href="qregion.html">QRegion</a> object. A rectangle which has been rotated or sheared may result in a non-rectangular region being returned.</p>
<p>Use the <a href="qmatrix.html#mapToPolygon">mapToPolygon</a>() or <a href="qmatrix.html#map">map</a>() function instead.</p>
