Using the Lat/Lng to pixel and reverse transformations to work out the Arrow head coords in LatLon is what the BDCC ArrowedPolyline code does. I agree that rendering is slow with lots of arrow heads drawn with polylines.
It might also be worth taking a look at the SVG/VML arrow demo which uses native VML/SVG to draw the arrow heads and the sub-classed Polyline (BdccPolyline) and try and mix the two. Both these demos are on http://www.bdcc.co.uk/Gmaps/BdccGmapBits.htm . If achievable, this should be a high performance solution for directed GPolylines on all browsers that support VML or SVG (most of the main ones). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
