buffer. This solves the issue mentioned in [2254] properly as it wasn't solved properly before. The bug is uncovered in cairo 1.10.0 and caused that images added to pdf surfaces did not appear at all. My guess is that newest cairo reads the pattern surface lazily when "trasnfering" it to the target surface and by the time it does it the cairo_pattern which owns the buffer has already been destroyed.
See INSTALL file for installation instructions Mapnik is an OpenSource C++/Python toolkit for developing GIS (Geographic Information Systems) applications. At the core is a C++ shared library providing algorithms/patterns for spatial data access and visualization. Essentially a collection of geographic objects (map, layer, datasource, feature, geometry), the library doesn't rely on "windowing systems" and can be deployed in any server environment. It is intended to play fair in a multi-threaded environment and is aimed primarily, but not exclusively, at web-based development. High-level Python bindings (boost.python) facilitate rapid application development, targeting zope3, django etc. Mapnik is a free software and is released under LGPL (GNU Lesser General Public Licence) (see COPYING) For further information see: - http://mapnik.org - http://trac.mapnik.org - http://ohloh.net/p/mapnik
