The mapping must be bijective, i.e. map a pair of real numbers to exactly one other pair of real numbers an vice versa, to facilitate a working inverse. Bijectiveness also implies completeness, i.e. for every pair of real numbers there must be another pair that is mapped upon them.<p> </dd> <dt><b>Since </b></dt> <dd>OOo 2.0 </dd> </dl> </td> </tr> </table> <hr> <a name="MethodsSummary"/><table border="1" width="100%" cellpadding="5" cellspacing="0" class="subtitle"> <tr> <td class="subtitle" colspan="2">Methods' Summary</td> </tr> <tr> <td class="imsum_left"><a href="#map">map</a></td> <td class="imsum_right">Forward 2D mapping function </td> </tr> <tr> <td class="imsum_left"><a href="#mapInverse">mapInverse</a></td> <td class="imsum_right">Inverse 2D mapping function. </td> </tr> </table> <a name="MethodsDetails"/><table border="1" width="100%" cellpadding="5" cellspacing="0" class="subtitle"> <tr> <td class="subtitle">Methods' Details</td> </tr> <tr> <td class="imdetail"><a name="map" class="membertitle">map</a><table border="0" width="96%" cellpadding="5" cellspacing="0" class="table-in-method" bgcolor="#ffffff" align="center"> <tr> <td><table class="table-in-method" border="0"> <tr> <td valign="top" colspan="3"><a href="RealPoint2D.html">RealPoint2D</a></td> </tr> <tr> <td valign="top"><b>map</b>(</td> <td valign="top">[in] <a href="RealPoint2D.html">RealPoint2D</a></td> <td valign="bottom"> aPoint );</td> </tr> </table> <hr> <dl> <dt><b>Description</b></dt> <dd>Forward 2D mapping function </dd> </dl> </td> </tr> </table> </td> </tr> <tr> <td class="imdetail"><a name="mapInverse" class="membertitle">mapInverse</a><table border="0" width="96%" cellpadding="5" cellspacing="0" class="table-in-method" bgcolor="#ffffff" align="center"> <tr> <td><table class="table-in-method" border="0"> <tr> <td valign="top" colspan="3"><a href="RealPoint2D.html">RealPoint2D</a></td> </tr> <tr> <td valign="top"><b>mapInverse</b>(</td> <td valign="top">[in] <a href="RealPoint2D.html">RealPoint2D</a></td> <td valign="bottom"> aPoint );</td> </tr> </table> <hr> <dl> <dt><b>Description</b></dt> <dd>Inverse 2D mapping function.</dd> <dd><p> The following invariant must hold: <code>map(mapInverse(p))=p</code>.
