The only way you can stop that is to keep your polygons from overlapping. It's not an "opacity adjustment" instead, it's the layers adding opacity together, just like if they were made from plastic and you overlaid one on top of the other.
It would be possible to trim your circles, but it would take a lot of processing power and computations, probably make your presentation meaningless. One way you could do it is to create a server side depiction of your circles as an image overlay, which would start out as all circles 100% opaque there by rending the overlapping circle problem moot, then when displaying it on a map, use the opacity of an overlay (GGroundOverlay has no opacity, you'd have to use one of the third party systems) to set the transparency of the overall image. Hope this helps. Maybe someone else has a better idea? -John Coryat http://maps.huge.info http://www.usnaviguide.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
