+<h2>DESCRIPTION</h2>
+
+<p>
+The <b>Map Swipe</b> is
+a <em><a href="wxGUI.html">wxGUI</a></em> component which allows the
+user to interactively compare two raster maps of the same area
+by revealing different parts of the raster maps.
+It is useful e.g. for comparing raster maps from different time periods.
+Map Swipe can be launched
+from the menu <tt>File -> Map Swipe</tt>.
+
+<p>
+Map Swipe allows to:
+
+<ul>
+  <li>switch rientation of the swipe line (horizontal or vertical)</li>
+  <li>zooming, panning</li>
+  <li>automatically load maps when opening Map Swipe with two selected raster maps in Layer Manager</li>
+</ul>
