*
|
|
* A dialog that uses a KPixmapRegionSelectorWidget to allow the user
|
|
* to select a region of an image. If you want to use special features
|
|
* like forcing the selected area to have a fixed aspect ratio, you can use
|
|
* pixmapRegionSelectorWidget() to get the pointer to the
|
|
* KPixmapRegionSelectorWidget object and set the desired options there.
|
|
*
|
|
* There are some convenience methods that allow to easily show a dialog
|
|
* for the user to select a region of an image, and just care about the selected
|
|
* image.
