Re: [Pymag-devel] Unable to render Polygons

[<jo...@fe...>]

I've just tried the latest code from svn, with mixed results. Some of  
my maps have polygons rendering again, but others that warn about  
Improper polygons now crash Mapsend/Vantagepoint.

Some of the warnings I can understand - polygons with only 2 points,  
or polygons that are 'open', but one example I saw has me confused...

I got this warning one one tonight -
WARNING Improper polygon found: [(144.844255, -38.373168800000002),  
(144.8432851, -38.373168800000002), (144.844255, -38.373168800000002)]
That shows a polygon with 3 points, and two of them have the same  
coordinates? That should be a valid polygon unless I'm missing  
something.

The nodes/way relating to that error are:

<node id="172752298" timestamp="2009-02-25T17:02:53Z"
