In the first definition, the <em>in_polys</em> and <em>out_polys</em> parameters can reference the same <em>Paths</em> object though in that case the calling code might be clearer if the second definition (accepting a single <em>Paths</em> parameter) is used.<br><br> <em>Note: There's currently no guarantee that polygons will be strictly simple since 'simplifying' is still a work in progress.</em><br><br> <img src="../../../../Images/simplify.png" alt="" border="0"><br> <img src="../../../../Images/simplify2.png" alt="" border="0"> <img src="../../../../Images/simplify3.png" alt="" border="0"> </p>
