<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>
|
|
|

</ul>
