• zoom

  public void zoom(double ratio)

  Zoom in or zoom out the map to a specified zoom percentage The scale of the map after zooming equals to the original scale multiplied by ratio, where, the ratio should be a positive value. When ratio is larger than 1, the map will be zoomed in; when ratio is less than 1, the map will be zoomed out.

  Parameters:

  ratio - the zoom percentage which must be positive.

• panOffset

  public void panOffset(double offsetX,
                        double offsetY)

  Pans this map by the specified distance.

  Parameters:

  offsetX - x

  offsetY - y

• viewEntire

  public void viewEntire()

  Displays the map in full extent.

• dispose

  public void dispose()

  Disposes the resources occupied by the object. After calling this method, this object will not be usable.

• refresh

  public void refresh()

  Redraw the current map and refresh the current map window.
