MapControl.ZoomToRegion(CoordPoint, CoordPoint, Double, Boolean) Method
Zooms the map to the specified region. Allows you to set whether the map should use a non-negative integer zoom level.
Namespace: DevExpress.XtraMap
Assembly: DevExpress.XtraMap.v24.1.dll
NuGet Package: DevExpress.Win.Map
Declaration
public void ZoomToRegion(
CoordPoint topLeft,
CoordPoint bottomRight,
double paddingFactor,
bool roundZoomLevel
)
Parameters
Name | Type | Description |
---|---|---|
topLeft | CoordPoint | The top-left coordinate of the region. |
bottomRight | CoordPoint | The bottom-right coordinate of the region. |
paddingFactor | Double | Specifies the size of the border around displayed map items. |
roundZoomLevel | Boolean | Specifies whether to round the zoom level value. |
Remarks
The padding factor is applied to the larger dimension of a region.
The following image shows an instance of a horizontal dimension that 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.
Example
The following code zooms a map into a region:
using DevExpress.XtraMap;
private void OnVectorLayerDataLoaded(object sender, DataLoadedEventArgs e) {
mapControl1.ZoomToRegion(
topLeft: new GeoPoint(61.6, 1.9),
bottomRight: new GeoPoint(48.1, 32.1),
paddingFactor: 0.3,
roundZoomLevel: true);
}
