<p>In this demo we show Qt's ability to perform affine transformations on painting operations.</p>
<p align="center"><img src="images/affine-demo.png" /></p><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>
<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>
