Hello I'm writing on a simple Frontend for the mapnik-toolchain. Currently you can call it like this:
osm-render --bbox 8.2011,49.9649,8.3278,50.0327 --size 8192x4096 I'd like to add another option like this: osm-render --bbox 8.2011,49.9649,8.3278,50.0327 --zoom 14 The combination of bbox-size (in lat/lon or maybe kilometers?) and output-size (in pixels) somehow leads to the ScaleDenominator used in the mapnik style, so i think it could be calculated to a zoomlevel and vice versa. Does anyone has a formular for that (especially bbox & zoom --> width & height) or is this just not possible?
