|
---|
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.
|
---|
