+ * @short A class to split a pixmap into several items.
+ *
+ * If you have a pixmap containing several items (icons), you can use this
+ * 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 );
+ * splitter.setItemSize( QSize( 20, 10 ));
+ *
+ * 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
