|

| 31 |
|

| 32 | In this demo we show Qt's ability to perform affine transformations
|
|---|
| 33 | on painting operations.

|
|---|
| 36 |
|
|---|
| 37 | Transformations can be performed on any kind of graphics drawn using QPainter.
|
|---|
| 38 | The transformations used to display the vector graphics, images, and text can be adjusted
|
|---|
| 39 | in the following ways:
|
|---|
| 40 |
|
|---|
| 41 | \list
|
|---|
| 42 | \o Dragging the red circle in the centre of each drawing moves it to a new position.
|
|---|
| 43 | \o Dragging the displaced red circle causes the current drawing to be rotated about the
|
|---|
| 44 | central circle. Rotation can also be controlled with the \key Rotate slider.
|
|---|
| 45 | \o Scaling is controlled with the \key Scale slider.
|
|---|
| 46 | \o Each drawing can be sheared with the \key Shear slider.
|
|---|
| 47 | \endlist
