[fusion-dev] Markers in Openlayers.

[Nolte, Tim]

If you look at the API for OpenLayers you'll find that their roadmap is pushing to retire the old Markers way of doing things in favor of just using Vector features. I have already implemented this to added a geocoded point to Fusion. Here is a sample of my code:

var map = Fusion.getMapById('Map');

var styleMap = new OpenLayers.StyleMap({
	"default": new OpenLayers.Style({
		graphicName: "${graphicName}",
		strokeColor: "${strokeColor}",
		strokeOpacity: "${strokeOpacity}",
		strokeWidth: "${strokeWidth}",
		fillColor: "${fillColor}",
		fillOpacity: "${fillOpacity}",
		pointRadius: "${pointRadius}",
		pointerEvents: "visiblePainted",
		label : "  ${label}",
		
		fontColor: "#000000",
		fontSize: "11px",
		fontFamily: "Arial",
		fontWeight: "bold",
		labelAlign: "${align}",
		labelXOffset: "${xOffset}",
		labelYOffset: "${yOffset}"
	})
});

// remove any existing Geocoded Point vector layers
for (var i=0; i<map.oMapOL.layers.length; i++) {
	var layer = map.oMapOL.layers[i];
	if (layer.name == 'Geocoded Points') { layer.destroy(); }
}
// create Geocoded Point vector layer
var vectorLayer = new OpenLayers.Layer.Vector('Geocoded Points', {styleMap: styleMap});
map.oMapOL.addLayers([vectorLayer]);
var newPoint = new OpenLayers.Geometry.Point(parseFloat(nLon), parseFloat(nLat), {style: "default"});
var pointFeature = new OpenLayers.Feature.Vector(newPoint);
pointFeature.attributes = {
	graphicName: "circle",
	strokeColor: "#000000",
	strokeOpacity: 1,
	strokeWidth: 1,
	fillColor: "#FFFFFF",
	fillOpacity: 1,
	pointRadius: 9,
	
	label: sLabel,
	align: 'lc',
	// positive value moves the label to the right
	xOffset: 50,
	// negative value moves the label down
	yOffset: -15
};
var newStar = new OpenLayers.Geometry.Point(parseFloat(nLon), parseFloat(nLat), {style: "default"});
var starFeature = new OpenLayers.Feature.Vector(newStar);
starFeature.attributes = {
	graphicName: "star",
	strokeColor: "#000000",
	strokeOpacity: 1,
	strokeWidth: 1,
	fillColor: "#0066CC",
	fillOpacity: 0.5,
	pointRadius: 8,
	
	label: '',
	align: 'lc',
	// positive value moves the label to the right
	xOffset: 0,
	// negative value moves the label down
	yOffset: 0
};
vectorLayer.addFeatures([pointFeature, starFeature]);

Hi Paul, 
did this get implemented?  I am very interested in Markers lately!
