+<h2>Affine Transformations</h2>
+</center>
+
+<p>In this demo we demonstrate Qt's ability to perform affine transformations
+on painting operations.</p>
+
+<p>Transformations can be performed on any kind of graphics drawn using
+QPainter. The transformations used to display the vector graphics, images,
+and text can be adjusted in the following ways:</p>
+
+<ul>
+  <li>Dragging the red circle in the centre of each drawing moves it to a new
+      position.</li>
+  <li>Dragging the displaced red circle causes the current drawing to be
+      rotated about the central circle. Rotation can also be controlled with
+      the <b>Rotate</b> slider.</li>
+  <li>Scaling is controlled with the <b>Scale</b> slider.</li>
+  <li>Each drawing can be sheared with the <b>Shear</b> slider.</li>
+</ul>
