Hi,

I am drawing a Rectangle (silverlight rectangle) in map. But It draws with the upper left corner in the Location I specified and I want to draw it in the center. How can I do that? is there a way to set a latitude / longitude  offset .

Is there some method to convert from pixel size (10pixels for instance) to coordinates size?

Kind regards,
Gonçalo

Hello Gonçalo,

You can align framework element around the location using HotSpot object. For example, to specify location at the center of the rectangle you can use following code:

Rectangle rect = new Rectangle()
{
    Width = 50,
    Height = 50,
    Fill = new SolidColorBrush(Colors.Red)
};
  
MapLayer.SetLocation(rect, new Location(42.7669999748468, 25.2819999307394));
HotSpot hotspot = new HotSpot()
{
    X = 0.5,
    Y = 0.5
};
MapLayer.SetHotSpot(rect, hotspot);
  
this.informationLayer.Items.Add(rect);
