Copy

public class MapView : UserControl, IComponentConnector

Public Class MapView
	Inherits UserControl
	Implements IComponentConnector

public ref class MapView : public UserControl, 
	IComponentConnector

type MapView =  
    class
        inherit UserControl
        interface IComponentConnector
    end

The MapView type exposes the following members.

Constructors

	Name	Description
	MapView	Initializes a new instance of the MapView class.

Properties

	Name	Description
	Center	Gets or sets the center of the map.
	CurrentEnvelope	Gets the bounding box of the visible map section while the map is in animation mode.
	CurrentScale	Gets the scale factor while the map is in animation mode. Defined in Logical units per pixel.
	CurrentX	Gets the logical x-coordinate while the map is in animation mode.
	CurrentY	Gets the logical y-coordinate while the map is in animation mode.
	CurrentZoom	Gets the floating tile level while in animation mode.
	FinalEnvelope	Gets the anticipated bounding box of the visible map section after the map was in animation mode / the current box while the map is in animation mode.
	FinalScale	Gets the scale factor after the map was in animation mode / the anticipated scale factor while the map is in animation mode. Defined in logical units per pixel.
	FinalX	Gets the x-coordinate after the map was in animation mode / the anticipated x-coordinate while the map is in animation mode.
	FinalY	Gets the y-coordinate after the map was in animation mode / the anticipated y-coordinate while the map is in animation mode.
	FinalZoom	Gets the level of detail according to the standard tiling scheme (float value).
	FitInWindow	Gets or sets a value indicating whether the map should be fitted in the window or not.
	IsAnimating	Gets a value indicating whether an animation is in progress. Returns true while the map performs a transition to a new map section.
	MaxZoom	Gets or sets the maximal level of detail according to the standard tiling scheme. The current detail level (see FinalZoom property) is corrected, if it is higher than the new maximum value.
	MetersPerPixel	Gets the number of meters spanned by one pixel.
	MinZoom	Gets or sets the minimal level of detail according to the standard tiling scheme. The current detail level (see FinalZoom property) is corrected, if it is lower than the new minimum value.
	OriginOffset	Gets the origin offset value for Deep Zoom
	Printing	Gets or sets a value indicating whether the printing of a map is in process.
	ZoomScale	Gets or sets the current zoom scale value.

Methods

	Name	Description
	InitializeComponent	InitializeComponent
	SetEnvelope(MapRectangle, Boolean)	Sets the visible map section to a bounding box, so the box is contained in the map section.
	SetEnvelope(MapRectangle, Boolean, Double)	Sets the visible map section to a bounding box, so the box is contained in the map section.
	SetXYZ(Double, Double, Double, Boolean)	Positions the map to a center and zoom factor.
	SetXYZ(Double, Double, Double, Boolean, Boolean)	Positions the map to a center and zoom factor.
	SetZoom	Sets the level of detail according to the standard tiling scheme.
	ZoomAround	Zooms around a point.

Events

	Name	Description
	ViewportBeginChanged	Event indicating the beginning of a change of the visible map section. This event is intended for more longtime actions (for example reading DB-objects), when the map section will change.
	ViewportEndChanged	Event indicating the ending of a change of the visible map section. It is the counterpart of the event.
	ViewportWhileChanged	Event indicating an intermediate view, when animation mode is active. It can be used to adapt the size of WPF objects, or other actions, which are not time-consuming. This event may called multiple times, when animation mode is active.

Fields

	Name	Description
	BackPaneCanvas	BackPaneCanvas Name Field
	CenterProperty	Dependency property for the center of the map. This enables animation, styling, binding, etc...
	EARTH_RADIUS	The earth radius of the map is 6371000.0 (so the main projection is PTV_Mercator).
	ForePaneCanvas	ForePaneCanvas Name Field
	GeoCanvas	GeoCanvas Name Field
	Layers	Layers Name Field
	LogicalSize	The size of the map in logical coordinates.
	ReferenceSize	An arbitrary value.
	ScaleProperty	Dependency property for the scale value of the map object.
	TopPaneCanvas	TopPaneCanvas Name Field
	ZoomAdjust	The zoom adjust is used to minimize rounding errors in deep zoom levels.
