Patch to expose more methods in the CAPI

Greetings GEOS-devel

I've attached a patch that exposes these C++ class methods as CAPI 
functions:

LineString::getPointN -> GEOSGetPointN
LineString::getStartPoint -> GEOSGetStartPoint
LineString::getEndPoint -> GEOSGetEndPoint
LineString::isClosed -> GEOSisClosed
LineString::getLength -> GEOSGetLength
LineString::getNumPoints -> GEOSGetNumPoints
Point::getX -> GEOSGetX
Point::getY -> GEOSGetY

Additionally I wrote a small test case for the new functions. Any 
feedback is greatly appreciated.
Thank you,

It's a good idea to submit patches to the Trac

http://trac.osgeo.org/geos/

by creating new ticket following instruction in
"Bug Reporting" section.

Good idea Mateusz, thank you.

I opened the following ticket:

Re: Patch to expose more methods in the CAPI

Alex and I work together at Ingres, so I'll more than happily take on
the commit 'responsibility' of this patch when it's vetted.

library benchmarks in benchmarks

Hi,

We have developed benchmarks to test performance (and functionality) of (Open Source) GIS / Geometry libraries.

Originally the tests were created to compare our library (GGL, recently accepted by Boost and renamed to Boost.Geometry) to other libraries, with respect to performance and functionality.

However, the test suite is broader than that because it can also be used to compare for example GEOS and CGAL. Therefore we propose to move it to the SVN http://svn.osgeo.org/osgeo/foss4g/benchmarking, it seems to fit there perfectly.

It currently compares C++ libraries (geos, cgal, gpc, wykobi, gtl, terralib, ggl) and a Java library (jts), for the functions area, centroid, convex hull, intersection, clip (=intersection with rectangle), simplify, within. But this can be extended.

There is also a specific test, "starcomb", for more 'challenging' intersections (done with a selection of the mentioned libraries only), and "triangle" (intersecting polygons with 1000ths of triangular holes)

I like to hear opinions if this is found a good idea, and if there are possibly people interested in extending tests, performing tests and/or maintenance.

Regards, Barend Gehrels


P.S. The testsuite is discussed on the geos-devel list before so I include this in the cc, apologies for cross postings.

Folks,

By the way, if OSGeo supports the idea of hosting, let's call it,
FOSS geometry libraries benchmark, I would like to take care of
submitting it to the benchmarks module in the SVN
and of further maintenance.

Comment:

 It's been long time without any action on this. I'm assigning it to nobody
 and suggest to close as wontfix.
