Yes. For efficiency, the API performs some of the lat/lng to pixel calculations of the polylines only once, at zoom level 17, rather than recalculating them whenever the zoom changes. If you create your custom map with less than "new GMercatorProjection(18)" that code will crash. [You need 18 zoom levels, numbered 0 to 17, in order for level 17 to exist]. As it happens, creating extra zoom levels for GProjections takes extremely negligible amounts of resources, so you might as well use "new GMercatorProjection(32)" like the Google maptypes do. -- Mike Williams http://econym.org.uk/gmap --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
