Hi Everyone,
My name is Cameron Alston and I will be working on the OpenJUMP project this
summer, specifically in implementing a stand-alone map labelling system. I'm
currently finishing up at UC Davis and I'll be attending UC Santa Cruz in the
fall for graduate school. I met up with Landon (
Hi,
Thank you for the answers about this topic.
ShapefileReader is not great but it just works.
I'll see what I can do to improve PolygonHandler a bit (following
Martin's and Larry's recommendations).
Moving to a recent geotools driver is another option which, I think,
needs more work and more t

When I last worked on the issue that is the topic of this thread (last year
sometime), I tried to use the geotools code to solve the problem, but it
seemed to be buggy so I abandoned it. I don't recall anything specific, but
I did make the effort.

if the current geotools (just checked they are 2.5.5 stable now)
shapefile reader/writer is more advanced why not aiming on using it .. i
once wrote a geotools reader/writer extension, that should be possible
these days as well ... only problem was that I had to convert the data
structure because i

The ShapefileReader code is really horrific, IMHO. We grabbed it from
an early release of GeoTools, and never upgraded it since it

Yes, 0 points are allowed to support empty geometries.

I have made the latest build of the JUMP Pilot Project source code
repository for OpenJUMP available here:
http://www.redefinedhorizons.com/resources.html
Under the "Software" section heading you will find a link to the
executable distribution and the source code distribution.
Please let me know

The second test is just paranoia that isPointInRing is not robust for
non-fixed point math. I haven't scanned the jts code to see what it
actually does.
@Larry : I replaced a quick 'ring in ring' t
