MapControl.ZoomToRegion(MapBounds, Boolean, Double) Method
Zooms the map to the specified region. Allows you to specify whether to use an integer zoom level.
Namespace: DevExpress.Xpf.Map
Assembly: DevExpress.Xpf.Map.v23.2.dll
NuGet Package: DevExpress.Wpf.Map
Declaration
public void ZoomToRegion(
MapBounds bounds,
bool roundZoomLevel,
double paddingFactor = 0.15
)Parameters
| Name | Type | Description |
|---|---|---|
| bounds | MapBounds | The bounds that specify a map region to display. |
| roundZoomLevel | Boolean | Specifies whether to round the zoom level value. |
Optional Parameters
| Name | Type | Default | Description |
|---|---|---|---|
| paddingFactor | Double | 0.15 | Specifies the size of the border around displayed map items. |
Remarks
The padding factor is applied to the larger dimension of the bounding box that contains visible items.
The following image shows an instance of a horizontal dimension that is larger than the vertical (“PF” means “Padding Factor” on images):
When the vertical dimension is larger than the horizontal, the zoom appears as follows:
Note that the padding factor is divided by two for each side of the region.
The following example zooms a map into a region, and applies an integer zoom level value:
private void OnWindowLoaded(object sender, RoutedEventArgs e) {
mapControl.ZoomToRegion(bounds: new MapBounds(new GeoPoint(51.30, 0.07), new GeoPoint(41.54, 12.3)), roundZoomLevel: true, paddingFactor: 0.15);
}
