<h2 id="details">Detailed Description</h2>
<p>The Matrix4x4 type provides a way to apply a transformation to an <a href="qml-qtquick-item.html">Item</a> through a 4x4 matrix.</p>
<p>It allows for a combination of rotation, scale, translatation and shearing by using just one tranformation provided in a 4x4-matrix.</p>
<p>The following example rotates a Rectangle 45 degress (PI/4):</p>
<pre class="qml">

  <span class="type"><a href="qml-qtquick-rectangle.html">Rectangle</a></span> {
