MapToScreen Method (MapView)
Converts a point in the coordinates of the map or scene to a point in screen coordinates. This method must be called on the MCT. Use QueuedTask.Run.
Parameters
- mapPoint
- The point that represents coordinates in a map.
Return Value
The converted point in screen coordinates.
Calculate Selection tolerance in map units
//Selection tolerance for the map in pixels
var selectionTolerance = SelectionEnvironment.SelectionTolerance;
QueuedTask.Run(() =>
{
//Get the map center
var mapExtent = MapView.Active.Map.GetDefaultExtent();
var mapPoint = mapExtent.Center;
//Map center as screen point
var screenPoint = MapView.Active.MapToScreen(mapPoint);
//Add selection tolerance pixels to get a "radius".
var radiusScreenPoint = new System.Windows.Point((screenPoint.X + selectionTolerance), screenPoint.Y);
var radiusMapPoint = MapView.Active.ScreenToMap(radiusScreenPoint);
//Calculate the selection tolerance distance in map uints.
var searchRadius = GeometryEngine.Instance.Distance(mapPoint, radiusMapPoint);
});
