<DIV><FONT size=2>Hi All,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> Dose GEOS supports buffer of
self-intersected polygon, just like 'POLYGON ((2 2,-2 -2,2 -2,-2 2,2 2))'.
I get the wrong polygon result with GEOSBuffer('POLYGON ((2 2,-2 -2,2 -2,-2 2,2
2))',0.5,8). I use newest verion.</FONT></DIV>
<DIV><FONT size=2> Thanks.</FONT></DIV>
