示例1: Expand
private Envelope Expand(Envelope e)
{
double factor = 0.6;
MapPoint centerMapPoint = e.GetCenter();
return new Envelope(centerMapPoint.X - e.Width * factor, centerMapPoint.Y - e.Height * factor,
centerMapPoint.X + e.Width * factor, centerMapPoint.Y + e.Height * factor);
}示例2: GetDistance
private static double GetDistance(Envelope extent)
{
// get the distance between the center of the current map extent and one of its corners
if (extent != null && !extent.IsEmpty)
{
var d = GeometryEngine.GeodesicLength(new Polyline(new PointCollection(extent.SpatialReference){ extent.GetCenter(), new MapPoint(extent.XMin, extent.YMin) },
extent.SpatialReference), GeodeticCurveType.GreatElliptic);
// to increase the chances of finding results make sure the smallest returned distance is 5 Kilometers.
return (d <= 5000.0) ? 5000.0 : d;
}
return 5000.0; // return a default distance of 5 Kilometers
}
