All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible

Direct Known Subclasses:

HttpMap

public class LudMapPanel
extends JPanel

Klasa z której dziedziczy HttpMap. Choć powstała na potrzeby LudProxy to zbudowana jest w sposób uniwersalny - może być wykorzystana w dowolnym projekcie, który potrzebuje mapy świata na której będzie rysować coś a podstawie współrzędnych geograicznych.

Plik graficzny z mapą został stworzony przez NASA i może być swobodnie wykorzystywany bez opłat (zobacz zasady licencyjne). Wikipedia twierdzi nawet, że znajduje się on w Domenie Publicznej, ale nie udało mi się tego potwierdzić. Grafikę można pobrać z serwisu NASA Visible Earth.

Method Detail

scale

public void scale()

Skaluje grafikę mapy do wymiarów komponentu.

paintComponent

public void paintComponent(Graphics g)

Rysuje grafikę mapy na komponencie. W razie potrzeby (jeśli wymiary komponentu zmieniły się od ostatniego wywołania meotdy) wywołuje najpierw metodę scale().

Overrides:

paintComponent in class JComponent

getMapUpperLeftCorner

public Point getMapUpperLeftCorner()

Zwraca punkt zawierajacy współrzędne (relatywne w stosunku do komponentu) lewego górnego punktu mapy

getMapCenter

public Point getMapCenter()

Zwraca punkt zawierajacy współrzędne (relatywne w stosunku do komponentu) środka mapy

CoordinatesToMapPoint

public Point CoordinatesToMapPoint(Coordinates c)

Przelicza współrzędne geograficzne na współrzędne na mapie (relatywne w stosunku do komponentu)

Parameters:

c - współrzędne geograficzne

Returns:

punkt w komponencie w którym grafika mapy odpowiada zadanym współrzędnym geograficznym
