However the available scale factors are hardcoded, so you can't just take an arbitrary device scale factor (window.devicePixelRatio in HTML5) and feed it in, as it might not match and you'll get HTTP errors out. I've got a provisional patch in for the example front-end which manually brackets to the available settings: https://github.com/kartotherian/kartotherian/pull/13 It'd be awesome to either expose the available scaling factors as a list via JSON API, or move the bracketing logic into the server side so you can send a query with your actual scale factor and get back one that will work. (If available scaling factors depend on the layer source being viewed, this might be more complicated.) > We would like to thank WMF Ops (especially Alex Kosiaris, Brandon Black, > and Jaime Crespo), services team, OSM community and engineers, and the > Mapnik and Mapbox teams.
