Affine Transformations
Files:
In this demo we show Qt's ability to perform affine transformations on painting operations.
![](images/affine-demo.png)
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:
- Dragging the red circle in the centre of each drawing moves it to a new position.
- Dragging the displaced red circle causes the current drawing to be rotated about the central circle. Rotation can also be controlled with the Rotate slider.
- Scaling is controlled with the Scale slider.
- Each drawing can be sheared with the Shear slider.
