Non-scalable elements in the style are only part of the problem. In general nearly all maps rely on the rasterization to perform necessary spatial frequency filtering or in other words: they cannot change output resolution independent from the level of detail. If you for example compare https://c.osm.rrze.fau.de/osmhd/6/35/18.png https://c.osm.rrze.fau.de/tiles/7/71/36.png or https://c.osm.rrze.fau.de/osmhd/8/133/85.png https://a.osm.rrze.fau.de/tiles/9/267/171.png or https://a.osm.rrze.fau.de/osmhd/8/132/75.png https://c.osm.rrze.fau.de/tiles/9/265/151.png You can see that apart from the styling differences between the zoom levels and the differences in label sizes these look identical. But for good readability on high resolution devices you do not want the additional details which are too small to be properly read leading to mushy results, you want better acuity with the same amount of detail. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ dev mailing list dev@openstreetmap.org https://lists.openstreetmap.org/listinfo/dev
