|
6 <p>In this demo we demonstrate Qt's ability to perform affine transformations |
|
7 on painting operations.</p> |
|
8 |
|
9 <p>Transformations can be performed on any kind of graphics drawn using |
|
10 QPainter. The transformations used to display the vector graphics, images, |
|
11 and 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> |
