Hi.
I have one more question for you.Please answer it if you can.
If i have a collection of Geometry object(MultilineString object) which are
the result of finding path between 2 point , i want to show them on the map.
But i do not know how to do.
I try this example in order to show Polygon object on the map but do not
achieve success:
map = new OpenLayers.Map('map');
var vectors = new OpenLayers.Layer.Vector("vector", {isBaseLayer:
true});
var feature = new OpenLayers.Feature.Vector(
OpenLayers.Geometry.fromWKT(
"POLYGON((28.828125 0.3515625, 132.1875 -13.0078125,
-1.40625 -59.4140625, 28.828125 0.3515625))"
)
);
vectors.addFeatures([feature]);
map.addLayers([vectors]);
or this example:
map = new OpenLayers.Map('map');
var features1 = [];
var vectors = new OpenLayers.Layer.Vector("vector",
{isBaseLayer: true});
var g = wkt.read("the data goes here");
features1.push(g);
vectors.addFeatures(features1);
map.addLayers([vectors]);
Both of them are not successful.
Could you give me another solution for showing Geometry object on the map.
Thanks
