\brief Demonstrates how affine transformations in QPainter work.
|
|
|
|
\brief In this example we show Qt's ability to perform affine transformations
|
|
on painting operations.

|
|
|
|
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:
|
|
|
|
\list
|
|
\li Dragging the red circle in the centre of each drawing moves it to a new position.
|
|
\li Dragging the displaced red circle causes the current drawing to be rotated about the
|
|
central circle. Rotation can also be controlled with the \uicontrol Rotate slider.
|
|
\li Scaling is controlled with the \uicontrol Scale slider.
|
|
\li Each drawing can be sheared with the \uicontrol Shear slider.
|
|
\endlist
