MapControl.ZoomToRegion(CoordPoint, CoordPoint, Double) Method

Zooms to the region described by its top left and bottom right points.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v18.2.dll

Declaration

C#

public void ZoomToRegion(
    CoordPoint p1,
    CoordPoint p2,
    double paddingFactor = 0.15000000596046448
)

VB.NET

Public Sub ZoomToRegion(
    p1 As CoordPoint,
    p2 As CoordPoint,
    paddingFactor As Double = 0.15000000596046448
)

Parameters

Name	Type	Description
p1	CoordPoint	A GeoPoint object.
p2	CoordPoint	A GeoPoint object.

Optional Parameters

Name	Type	Default	Description
paddingFactor	Double	0.150000005960464	A Double object, which tunes the border size around the region.

Remarks

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

C#

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

VB.NET

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.
