<p>In this demo we demonstrate Qt's ability to perform affine transformations on painting operations.</p>
29
<center><img src="images/affine-demo.png" /></center><p>Transformations can be performed on any kind of graphics drawn using <a href="qpainter.html">QPainter</a>. The transformations used to display the vector graphics, images, and text can be adjusted in the following ways:</p>
31
<li>Dragging the red circle in the centre of each drawing moves it to a new position.</li>
32
<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>
33
<li>Scaling is controlled with the <b>Scale</b> slider.</li>
34
<li>Each drawing can be sheared with the <b>Shear</b> slider.</li>
