<html><center><h2>Affine Transformations</h2></center><p>In this demo we demonstrate Qt's ability to perform affine transformationson painting operations.</p><p>Transformations can be performed on any kind of graphics drawn usingQPainter. 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></html>
