LatLngBounds

Namespace: Wisej.Web.Ext.GoogleMaps

Assembly: Wisej.Web.Ext.GoogleMaps (4.1.0.0)

A LatLngBounds instance represents a rectangle in geographical coordinates, including one that crosses the 180 degrees longitudinal meridian.

public class LatLngBounds

An instance is returned in Value when the "bounds" property of the map changes. The class doesn't validate, clamp or wrap the values; the ranges described for each property are applied by the Google Maps library.

Example:

Reading the visible area of the map:

private void googleMap1_MapPropertyChanged(object sender, MapPropertyChangedEventArgs e)
{
    if (e.Name == "bounds" && e.Value is LatLngBounds bounds)
        this.labelBounds.Text = bounds.ToString();
}

Constructors​

Instance member LatLngBounds()​

Initializes a new instance of the LatLngBounds class with all the coordinates set to 0.

Properties​

Instance member East​

Double: Returns or sets the east longitude in degrees. Values outside the range [-180, 180] will be wrapped to the range [-180, 180). For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.

Instance member North​

Double: Returns or sets the north latitude in degrees. Values will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.

Instance member South​

Double: Returns or sets the south latitude in degrees. Values will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.

Instance member West​

Double: Returns or sets the west longitude in degrees. Values outside the range [-180, 180] will be wrapped to the range [-180, 180). For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.
