Yes. If we did proper projection, we could cut the number of inkscape calls by a factor of 10. Cutting a full zoom level inkscape in 256x256 tiles rather than doing one y-stripe at a time would be beneficial (from a render time perspective) spaetz _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/listinfo/tilesathome
