Ok, I've done it using something like this:
[code]
var pathPoints = "";
var deliveryLine = deliverDirections.getPolyline();
var pointInc = 1;
// calculate the increment - for cases where there is a large
number of points
if(deliveryLine.getVertexCount() > <?
=GOOGLE_MAPS_STATIC_MAXPOINTS;?>){
pointInc = parseInt(deliveryLine.getVertexCount() / <?
=GOOGLE_MAPS_STATIC_MAXPOINTS;?>);
}
// build a string containing the list of points
for(var i = 0; i < deliveryLine.getVertexCount(); i+=pointInc){
deliveryPoint = deliveryLine.getVertex(i);
pathPoints += ((pathPoints != "")?"|":"")
+deliveryPoint.toUrlValue();
}
// make sure the last point gets added
if(i > deliveryLine.getVertexCount()){
deliveryPoint =
deliveryLine.getVertex(deliveryLine.getVertexCount()-1);
pathPoints += ((pathPoints != "")?"|":"")
+deliveryPoint.toUrlValue();
}
[/code]
Basically that lets me have the PHP constant
GOOGLE_MAPS_STATIC_MAXPOINTS defined to the maximum number of points I
will allow for the polyline on the static map.... seems to work
nicely, and actually creates a smoother line when the map is zoomed
out far enough that there'd be too many points.
I'm still curious to hear about other possible solutions... or if
there are plans to actually include proper directions rendering into
the static maps API?
Cheers,
