Removes vertices: +

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)
that are within the specified distance of an adjacent vertex
that are within the specified distance of a semi-adjacent vertex together with their out-lying vertices

+ +

Vertices are semi-adjacent when they are separated by a single (out-lying) vertex.

The distance 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.)

C++ only: This function is overloaded. In the first definition, the in_polys and out_polys parameters can reference the same Paths object though in that case the calling code might be clearer if the second definition (accepting a single Paths parameter) is used.
