public void ZoomToRegion(
    CoordPoint p1,
    CoordPoint p2,
    double paddingFactor = 0.15
)

Public Sub ZoomToRegion(
    p1 As CoordPoint,
    p2 As CoordPoint,
    paddingFactor As Double = 0.15
)

Name	Type	Description
p1	CoordPoint

A GeoPoint object.

| | p2 | CoordPoint |

A GeoPoint object.

Name	Type	Default	Description
paddingFactor	Double	0.15

A Double object, which tunes the border size around the region.

Note that the padding factor is applied to the larger dimension of the region.

The following image shows an instance when the horizontal dimension is larger than the vertical. (“PF” means “Padding Factor” on an image)

When vertical dimension larger than the horizontal, the zoom appears as follows.

Note that the padding factor is divided by two for each side of the region.

In the instance of the following code

csharp

GeoPoint p1 = new GeoPoint(10, 10);
GeoPoint p2 = new GeoPoint(30, 60);
mapControl.ZoomToRegion(p1, p2, 0.3);

Dim p1 As New GeoPoint(10, 10)
Dim p2 As New GeoPoint(30, 60)
map.ZoomToRegion(p1, p2, 0.3)

the result should look like the following.
