Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v22.1.dll

NuGet Package: DevExpress.Win.Map

Declaration

C#

public void ZoomToRegion(
    CoordPoint topLeft,
    CoordPoint bottomRight,
    double paddingFactor
)

VB.NET

Public Sub ZoomToRegion(
    topLeft As CoordPoint,
    bottomRight As CoordPoint,
    paddingFactor As Double
)

Parameters

Name	Type	Description
topLeft	CoordPoint	A CoordPoint class descendant object.
bottomRight	CoordPoint	A CoordPoint class descendant object.
paddingFactor	Double	A Double object, which tunes the border size around the region.

Remarks

Note that 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)

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

In the instance of the following code

C#

GeoPoint topLeft = new GeoPoint(50, 15);
GeoPoint bottomRight = new GeoPoint(60, 10);
map.ZoomToRegion(topLeft, bottomRight, 0.4);

VB.NET

Dim topLeft As New GeoPoint(50, 15)
Dim bottomRight As New GeoPoint(60, 10)
map.ZoomToRegion(topLeft, bottomRight, 0.4)

the result should look like the following.
