Map (gb.map)

This class acts like the drawing engine for the map.

After the initialization time, you only have to change the X, Y, Width and Height properties and call the Draw method to draw a map anywhere.

This class is creatable.

This class acts like a read-only array.

This class is enumerable with the FOR EACH keyword.

Static properties
Debug   Returns or sets the Debug messages

Properties
Bounds   Returns the lat/lon coordinates at the limits of the drawed map.
Center   Returns or sets the center point of the map
Count   Returns the number of Map Layers, both _MapShape and _MapLayer layers.
DefaultCache   Returns or sets the default cache path for storing Tiles Layer files.
Height  
Left  
MaxZoom   Returns or sets the maximum Map zoom level
PixelBox  
Proxy   Returns an _MapProxy virtual object used for defining Proxy and Authentication parameters.
Top  
Width  
X  
Y  
Zoom   Returns or sets the actual Map zoom level

Methods
AddShape   Adds a new _MapShape Layer to the current Map.
AddTile   Adds a new _MapTile Layer from remote server or local cache to the current Map
Draw  
Exists   Returns if a given _MapShape or _MapLayer Layer actually exists
GetShape   Returns an existing _MapShape Layer object.
GetTile   Returns an existing _MapTile Layer object
Grab   Return an image of the given bounds, with the given Width and Height, with the given margin arround. If the zoom is not defined then the better rendering zoom is used.
MapPointToPixelRel   Return a Point relative to the view from a MapPoint
PixelToMapPointRel   Return a MapPoint from a point relative to the view
Refresh  
Remove   Removes a Layer
Resize  

Events
Draw  
Refresh  

Examples

This is an example of how to initialize the map:

Private hMap as New Map

Public Sub _New()

  With hMap.AddTile("OpenStreet", "http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png")

    .Copyright = "OpenStreetMap contributors"

  End With

End

Public Sub DrawingArea1_Draw()

  hMap.Width = Draw.Width
  hMap.Height = Draw.Height
  hMap.Draw()

End
