[Mapserver-users] PERL mapscript polygon shapefile creation

[Lowell Filak]

Yes, the code for creating a circle polygon based on a center point and a radius is at:
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PerlMapScriptExamples35ex9
It also turns out that I had a bug/feature in that code where the closing line segment was never written to the shape but the shape closed anyways!?
As strange as it may seem the code works.
