Hello everybody, I try this question in the user list, but
without any answer. So I try it here, I'm displaying a GPX
tracks with some waypoints. I'm using this:
var myStyleMap = new OpenLayers.StyleMap({
"default": new OpenLayers.Style({
pointRadius: 5,
fillColor: "darkred",
strokeColor: "red",
strokeWidth: 4
})
});
var lgpx = new OpenLayers.Layer.Vector("Ruta", {
protocol: new OpenLayers.Protocol.HTTP({
url: "my.gpx",
format: new
OpenLayers.Format.GPX({extractWaypoints: true, extractRoutes: true,
extractAttributes: true})
}),
strategies: [new OpenLayers.Strategy.Fixed()],
styleMap: myStyleMap,
projection: new OpenLayers.Projection("EPSG:4326")
});
map.addLayer(lgpx);
This show tracks and waypoints, nice. But now I want something a bit
complex,
that is have a different color to each track. So first i try to use this
var context = {
getColor: function(feature) {
return "red";
}
};
var myStyleMap = new OpenLayers.StyleMap({
"default": new OpenLayers.Style({
pointRadius: 5,
fillColor: "darkred",
strokeColor: "${getColor}",
strokeWidth: 4
},{context: context})
});
var lgpx = new OpenLayers.Layer.Vector("Ruta", {
protocol: new OpenLayers.Protocol.HTTP({
url: "my.gpx",
format: new
OpenLayers.Format.GPX({extractWaypoints: true, extractRoutes: true,
extractAttributes: true})
}),
strategies: [new OpenLayers.Strategy.Fixed()],
styleMap: myStyleMap,
projection: new OpenLayers.Projection("EPSG:4326")
});
map.addLayer(lgpx);
But now, only the inside of the waypoints are rendered. So the
"$getColor" is not working. This should work also here ?
Best regards
