Mark Cave-Ayland 74949bc755 Update LWGEOM unparser to (E)WKT/WKB to resturn a LWGEOM_UNPARSER_RESULT structure instead of just the WKT/WKB character array. This is the same work done for r3023 but applied to the unparser instead. git-svn-id: http://svn.osgeo.org/postgis/trunk@3026 b70326c6-7e19-0410-871a-916f4a2858ee		2008-09-28 19:48:17 +00:00

Makefile	Add an example of how the liblwgeom API can be used by other C programs to manipulate geometries and output the result. Currently the unparser.c program shows how a geometry can be constructed "on the fly" and then exported in both WKT and HEXWKB formats; however it gives programmers the potential to devise some very unique processing tools which can generate files that can be loaded into PostGIS.	2008-09-16 22:29:54 +00:00

liblwgeom API examples
======================

This directory contains examples of how to use the liblwgeom API from other C programs. Since liblwgeom is a static library, it is currently limited to tools within the PostGIS source tree. However, it is envisaged that programmers may make use of this interface to produce other geometry processing tools that can input and output WKT and WKB (which is, of course, easily loadable into PostGIS).
