| <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> |
