A vertex defined as level P will appear on maps at level zero and closer. A point at level B will appear on maps at zoom 14 and closer. So you might think that making the end points "B" (for the sake of argument) will mean that the line is only plotted at zoom 14 and closer. But it doesn't work like that: the API assumes that if you are adding a line, you want it to appear; otherwise there would be no point in adding it. So the calculations require that the end points are coded P. If you want the line not to appear at zooms below some level, then you need either to implement some sort of overlay manager which can handle polylines or simply use a zoomend listener to show or remove the line depending on the zoom level. -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
