ACKNOWLEDGEMENTS The example shapefile set is taken from http://gdal.velocet.ca/projects/shapelib/eg_data/ the Shapelib examples. INSTALLATION To install, unzip and untar the archive. In the directory created type perl Makefile.pl make make test make install Geo::Shapelib.pm requires Frank Warmerdam's Shapefile C Library. It (version 1.2.10) is included into this distribution and it is used by default. Edit the Makefile.PL if you already have the library. Shapelib is available from www.maptools.org. Documentation is in the module file and will be added onto perllocal.pod as usual. DESCRIPTION Geo::Shapelib.pm is a Perl extension for reading and writing shapefiles as defined by ESRI(r) using Frank Warmerdam's Shapefile C Library Mails from Leif Pedersen: Wed, 12 Feb 2003 16:05:38 -0600 (CST) Hi. I work for Meridian Environmental Technology Inc. We have found your Perl module for Shapelib very useful at our company, and recently we have improved on it. I would like to offer our changes to be included in your next release, if you are interested. I believe we have enough to justify another release. My primary objective was to addethe ability to read one shape at a time out of the shape file. Many of our shape files are large enough to make the machine swap. Some would require several GB of memory to load as a single Perl structure. We also added a couple of options to make the structures easier to deal with. The most useful is the XS wrapper will optionally store the verticies as arrays in the appropriate parts. This is much easier if the script needs to deal with parts separately. While I was at it, I fixed a few bugs. Most of them are minor: - There was a memory leak in Shape.xs. newRV_inc was used to create references in the data structure that was returned. This left the reference count off by one, preventing the memory from being freed. This was fixed by substituting newRV_noinc. - Some data returned by shapelib as doubles were being stored with newSViv(), truncating them to ints. Vertices were done correctly, so this was minor. - svREFCNT_dec() should be used in place of free() for Perl structures. This ensures both that data is not freed until its ref count is zero, and it ensures that all data pointed to by these structures is freed. I've not finished this fix, but it is minor since it only happens when memory allocations fail, which Perl does not always handle gracefully anyway. I'm not quite done, but I would be happy to send you what I have so far. I think I've maintained back compatibility. I have not done any work on creating a shape file one shape at a time. 8<--- Thu, 13 Feb 2003 12:56:16 -0600 (CST) Cool. There's still a couple minor things left, marked with XXX. A user who is upgrading "shouldn't" have anything break, but I've not thoroughly checked that the output data structure in the default format is the same as it was before. I've only changed Shape.pm and Shape.xs and I did not touch changelog. 8<--- Thu, 13 Feb 2003 17:05:06 -0600 (CST) I've fixed one of the XXXs.
