Namespace: ThinkGeo.UI.XamarinForms.Adapters

Class IMapViewAdapter.

public interface IMapViewAdapter : IMapElementAdapter, System.IDisposable

Implements IMapElementAdapter, IDisposable

Properties¶

AdornmentOverlayAdapter¶

Gets or sets the adornment overlay.

public abstract IAdornmentOverlayAdapter AdornmentOverlayAdapter { get; }

Property Value¶

IAdornmentOverlayAdapter
The adornment overlay.

ZoomLevelSet¶

This property gets or sets the ZoomLevelSet used for the MapView control.

public abstract ZoomLevelSet ZoomLevelSet { get; set; }

Property Value¶

ZoomLevelSet

MapUnit¶

Gets or sets the map unit used by the MapControl.

public abstract GeographyUnit MapUnit { get; set; }

Property Value¶

GeographyUnit

Remarks:

The MapUnit reflects the data unit.

MinimumScale¶

public abstract double MinimumScale { get; set; }

Property Value¶

Double

MaximumScale¶

public abstract double MaximumScale { get; set; }

Property Value¶

Double

MapRotation¶

public abstract float MapRotation { get; set; }

Property Value¶

Single

CurrentExtent¶

Gets or sets the current extent of the MapControl.

public abstract RectangleShape CurrentExtent { get; set; }

Property Value¶

RectangleShape

Remarks:

The current extent stands for the extent of current position, this is very important metrics to caculate the scale.

Methods¶

Pan(PanDirection, Int32)¶

void Pan(PanDirection direction, int percentage)

Parameters¶

direction PanDirection

percentage Int32

Pan(Single, Int32)¶

void Pan(float degree, int percentage)

Parameters¶

degree Single

percentage Int32

Pan(Single, Single)¶

void Pan(float offsetScreenX, float offsetScreenY)

Parameters¶

offsetScreenX Single

offsetScreenY Single

ZoomIn(Int32)¶

void ZoomIn(int percentage)

Parameters¶

percentage Int32

ZoomOut(Int32)¶

void ZoomOut(int percentage)

Parameters¶

percentage Int32

ZoomIn()¶

Zooms the map in for one level.

void ZoomIn()

ZoomOut()¶

Zooms the map out for one level.

void ZoomOut()

ZoomInByAnchorPoint(ScreenPointF)¶

void ZoomInByAnchorPoint(ScreenPointF touchPosition)

Parameters¶

touchPosition ScreenPointF

ZoomTo(BaseShape)¶

This method zooms current map to the target shape.

void ZoomTo(BaseShape targetExtent)

Parameters¶

targetExtent BaseShape
A ractangle shape to locates the map.

Remarks:

When calling this method, it doesn't refresh existing Tiles on the current map. For example, if using a TileOverlay such as LayerOverlay; a layer style is changed, Refresh method is proper to call.

ZoomTo(PointShape, Double)¶

This method zooms current map to a specified position and scale.

void ZoomTo(PointShape worldCenter, double targetScale)

Parameters¶

worldCenter PointShape
A world center to zoom the map to.

targetScale Double
A double value indicates the scale to zoom the map to.

Remarks:

When calling this method, it doesn't refresh existing Tiles on the current map. For example, if using a TileOverlay such as LayerOverlay; a layer style is changed, Refresh method is proper to call.

ZoomToScale(Double)¶

Zooms the map to a provided scale. This method will simulate the ZoomToScale interaction.

void ZoomToScale(double targetScale)

Parameters¶

targetScale Double
A target scale to zoom the map.

Refresh()¶

This method will simulate the Refresh interaction. Refreshes current map control.

void Refresh()

Remarks:

Refreshes all the existing overlays and map tools.

Refresh(IEnumerable<Overlay>)¶

This method will simulate the Refresh interaction. Refreshes a specified overlay collection.

void Refresh(IEnumerable<Overlay> overlays)

Parameters¶

overlays IEnumerable<Overlay>
A collection of overlay to be refreshed.

Refresh(Overlay)¶

This method will simulate the Refresh interaction. Refreshes a specified overlay.

void Refresh(Overlay overlay)

Parameters¶

overlay Overlay
Overlay to be refreshed.

CenterAt(PointShape)¶

Locates the map center to the specified world point.

void CenterAt(PointShape worldCenter)

Parameters¶

worldCenter PointShape
A world point to locate the map.

ZoomToPreviousExtent()¶

Zooms to previous extent.

void ZoomToPreviousExtent()

ZoomToNextExtent()¶

Zooms to next extent.

void ZoomToNextExtent()
