6<p>In this demo we demonstrate Qt's ability to perform affine transformations
7on painting operations.</p>
8
9<p>Transformations can be performed on any kind of graphics drawn using
10QPainter. The transformations used to display the vector graphics, images,
11and text can be adjusted in the following ways:</p>
12
13<ul>
14 <li>Dragging the red circle in the centre of each drawing moves it to a new
15 position.</li>
16 <li>Dragging the displaced red circle causes the current drawing to be
17 rotated about the central circle. Rotation can also be controlled with
18 the <b>Rotate</b> slider.</li>
19 <li>Scaling is controlled with the <b>Scale</b> slider.</li>
20 <li>Each drawing can be sheared with the <b>Shear</b> slider.</li>
21</ul>
