i've seen two approaches: 1. render to PDF/PS and rasterise/print that at whatever scale you want. this means no mucking about with the style file, but some features (e.g: transparency, text halo-ing) sometimes don't come across the same as they do on the rendered tiles. 2. alter the style file so that everything is ~3 times bigger. this means everything will render right, but is a pain to do by hand. both approaches give comparable results. for the best results, replace the icons with a scalable icon set rendered at 3 times their normal size. >> 2. >> When rendering the whole world with coordinates like this: >> >> # unused: ll = (4.5, 46, 16, 56) # Germany >> ll = (-180.0, -90.0, 180.0, 90.0) # World >> >> Then i just get an empty file (just background). >> >> Is this related to the scale denominators in osm.xml? > > It likely is a combination of the scale and potentially a lack of the coast > shapefiles... The lowest level of detail just has the coast line rendered > from the shapefiles... i think its more likely to be that -90/+90 lat project to infinity in the mercartor projection. if you want a square image, use -85.0511/+85.0511 lat. see also http://wiki.openstreetmap.org/wiki/Slippy_map_tilenames#X_and_Y cheers, matt _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
