Hi everybody

I've used this library in some other projects we have at our company (http://www.xoomcode.com).

As you may have noticed, there aren't many ways to add a marker to the existing mapping libraries.

Mainly because they aren't very active.... or still on developing phase, that's why I decided that we needed a common way to handle this problem, and it would be nice if we can use the same solution on multiple projects.

At our company, we've developed an open source solution in the last time, ASMarkers (http://code.google.com/p/asmarkers/).

The main goal of ASMarkers it's to provide a nice and clean (or small and hackeable) solution to this particular problem.

The library currently is on an early beta stage, and being actively developed, but it can be used without any trouble.

It's our little contribution to the Open GIS Community, so please feel free to play and use it as you want.

Hello,

i was playing around with the Polyline Overlay drawing a route on a map. Unfortunately the polyline had some circles in it, because every line segment in it was drawn with a moveTo and lineTo command, so that it could be clipped. See the circles in the following picture:



The circles always appear, when not using alpha = 1.

So i thought, why not only call a new moveTo command when the previous line segment did not have to be drawn. So I extended the PolylineClip class and overrode the updatePolyline function as following:

override public function updatePolyline(polyline:Polyline):void
{
var w:Number = map.getWidth() * 2;
var h:Number = map.getHeight() * 2;

var boundaryWindow:Rectangle=new Rectangle(-w/2,-h/2,w,h);

var commands:Vector.<int> = new Vector.</int><int>();
var data:Vector.</int><number> = new Vector.</number><number>();
var nextCommand:int = GraphicsPathCommand.MOVE_TO;

// Calculate local coordinates for each point
for (var i:uint = 1; i < polyline.locationsArray.length;i++)
{
var p1:Point = map.locationPoint(polyline.locationsArray[i - 1] as Location, this);
var p2:Point = map.locationPoint(polyline.locationsArray[i] as Location, this);
if (clipLineToRect(p1, p2, boundaryWindow)) {
commands.push(nextCommand);
nextCommand = GraphicsPathCommand.LINE_TO;
data.push(p1.x, p1.y);
} else {
nextCommand = GraphicsPathCommand.MOVE_TO;
}
}
this.graphics.lineStyle(polyline.lineThickness,polyline.lineColor,polyline.lineAlpha,polyline.pixelHinting,polyline.scaleMode,polyline.caps,polyline.joints,polyline.miterLimit);
this.graphics.drawPath(commands, data);
}
</number>

(SORRY: The forum messed up the code a little, it's supposed to be var commands:Vector.<int> = new Vector.<int>(); and in the data one the theres the same problem)

As you can see, I am targeting flash player 10 with this solution already using the vector type and the drawPath command. Now the result looks like this:



So now I would like to know, what you think about this solution. Would there have been another possibility to achieve this without subclassing PolylineClip? Or would there be a better way to do this with subclassing PolylineClip?

Or is there a chance of getting this into the modestmaps api, so that i can throw my subclass away and it always acts like this?

I wrote a google maps provider and Ingit.ru map provider.
You can use it as you like
