[geos-devel] Something wrong with GEOSEnvelope function in 3.1.0?

[Obe, Regina]

LiN ,

I'm using GEOS 3.1.0 as well.  However on further inspection it looks like PostGIS uses its own implementation of Envelope and not the GEOS one, so you could very well be right that there is something wrong with that GEOS function.

Unfortunately I don't know enough about GEOS to test it apart from PostGIS.  

Maybe Mateusz or Sandro or Paul can confirm the issue.


Thanks,
Regina

Hi Regina,
        The GEOS' Version I used is "3.1.0". Today, I use
GEOSEnvelop("LINESTRING(1 3,1 6)") again, what a pity, it don't return the
result like what you said. In my program, the result is "POLYGON ((1  3, 1
3, 1  6, 1  6, 1 3))". So I want to ask you which version of GEOS are you
using?
