Hello, i downloaded mapnik-0.6.0 yesterday, compiling and installing (also with osm plugin) worked fine.
I got some example python scripts and tried to render a map, but did not succeed. I downloaded a file "example.osm" and additionally exported a region as OpenStreetMap XML Data, Permalink: http://www.openstreetmap.org/?lat=47.7822&lon=9.1346&zoom=13&layers=B000FTF I also downloaded osm-styles.xml and osm.xml from trac.mapnik.org . I'd like to render the map that i downloaded using python into a PNG and use the styles and rules defined in osm-styles.xml. My understanding is the following, can anybody please correct me when i'm wrong? I need to create a mapnik.Map import mapnik m = mapnik.Map(600, 600, "+proj=latlong +datum=WGS84") And then i try to create Layers for all the Styles i'd like to use, set the datasource to the osm file that i downloaded, set the zoom and render it. st = ['world', 'world-1', 'builtup', 'places', 'text', 'water'] ostyle = '/local/ftp/osm/osm-styles.xml' osm = mapnik.Osm(file='/local/ftp/osm/bodensee.osm') for s in st: lyr = mapnik.Layer(s, "+proj=latlong +datum=WGS84") lyr.datasource = osm lyr.styles.append(s) m.layers.append(lyr) mapnik.load_map(m, ostyle) m.zoom_to_box(lyr.envelope()) mapnik.render_to_file(m, 'world.png', 'png') But world.png is just empty. Seems i'm doing something wrong, is it ok to use mapnik.load_map() to load the styles? I did not find anything in the documentation. Thanks for any hints, Torsten. _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
