- * class to get the coordinates of each item.
- *
- * For example, if you have a pixmap with 25 items and you want to get the
- * 4th item as a pixmap (every item being 20x10 pixels):
- * \code
- * KPixmapSplitter splitter;
- * splitter.setPixmap( somePixmap );

- *
- * QPixmap item( 20, 10 );
- * item.fill( Qt::white );
- * QRect rect = splitter.coordinates( 4 );
- * if ( !rect.isEmpty() )
- * bitBlt( &item, QPoint(0,0), &somePixmap, rect, CopyROP );
- * \endcode
