  52 An STL random access traversal iterator over a model of <a class="el" href="g_i_l_0346.html" title="Pixel concept - A color base whose elements are channels.">PixelConcept</a>.
  53 <p>
  54 GIL's iterators must also provide the following metafunctions:<ul>
  55 <li><code>const_iterator_type&lt;Iterator&gt;</code>: Returns a read-only equivalent of <code>Iterator</code> </li><li><code><a class="el" href="g_i_l_0550.html">iterator_is_mutable&lt;Iterator&gt;</a></code>: Returns whether the given iterator is read-only or mutable</li><li><code>is_iterator_adaptor&lt;Iterator&gt;</code>: Returns whether the given iterator is an adaptor over another iterator. See <a class="el" href="g_i_l_0310.html" title="Iterator adaptor is a forward iterator adapting another forward iterator.">IteratorAdaptorConcept</a> for additional requirements of adaptors.</li></ul>
