Comment:
I cannot confirm the fix for 1.57.0. The following code ...
{{{
_intPolygon polygon;
boost::geometry::read_wkt("MULTIPOLYGON(((4287 2160,5984 2160,4287
2160)))", polygon);
boost::geometry::remove_spikes(polygon);
}}}
... yields the following result:
{{{
MULTIPOLYGON(((4287 2160))))
}}}
As far as I can tell from our discussions, the correct result would be the
empty multi-polygon. Here is the summary of my understanding of this
issue:
