<p class="Body"> Removes vertices:

|
<ul>
|
|
|
|
<li>that join co-linear edges, or join edges that are almost co-linear (such that if the vertex was moved no more than the specified distance the edges would be co-linear)</li>
|
|
|
|
<li>that are within the specified distance of an adjacent vertex</li>
|
|
|
|
<li>that are within the specified distance of a semi-adjacent vertex together with their out-lying vertices</li>
|
|
|
|
</ul> </p>
|
|
|
|
<p class="Body"> Vertices are <em>semi-adjacent</em> when they are separated by a single (out-lying) vertex.<br><br> The <em>distance</em> parameter's default value is approximately √2 so that a vertex will be removed when adjacent or semi-adjacent vertices having their corresponding X and Y coordinates differing by no more than 1 unit. (If the egdes are semi-adjacent the out-lying vertex will be removed too.)<br><br> C++ only: This function is overloaded. In the first definition, the <em>in_poly</em> and <em>out_poly</em> parameters can reference the same <em>Path</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> <img src="../../../../Images/clean1.png" alt="" border="0"> <img src="../../../../Images/clean2.png" alt="" border="0"> </p>
