+ * 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

+ * 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.
