Interface GeoGraphable

All Known Implementing Classes:

CalibratedMap, TiledMap

public interface GeoGraphable

Object capable of converting Geo points into a graphic context.

Method Summary

ewe.fx.Point	getMapPointFromPosition(GeoPoint pos, GeoDirection tmp, ewe.fx.Point pt) Compute X and Y on map from geo position.
GeoPoint	getPointFromMap(int xx, int yy, GeoPoint dest) Compute lat and long from position on map.

Method Detail

getMapPointFromPosition

ewe.fx.Point getMapPointFromPosition(GeoPoint pos,
                                     GeoDirection tmp,
                                     ewe.fx.Point pt)

Compute X and Y on map from geo position.

Parameters:

pos - geo position to transpose.

tmp - GeoDirection reference to compute intermediate direction. If null a new object is allocated.

pt - point on bitmap image to compute. If null a new Point object is allocated.

Returns:

Computed point. Should be pt or a new Point object.

getPointFromMap

GeoPoint getPointFromMap(int xx,
                         int yy,
                         GeoPoint dest)

Compute lat and long from position on map.
