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.

Diese Klasse ist erstellbar.

Diese Klasse verhält sich wie ein nur lesbar-Array.

Mit dem FOR EACH-Schlüsselwort ist diese Klasse zählbar.

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
