问题
I\'m working with OpenStreet Maps in Java with JMap Viwer http://wiki.openstreetmap.org/wiki/JMapViewer I can load the maps and everything ok but I don\'t know how to draw a line between two points from a latitude and longitude.
Any body know the function to draw this kind of lines?
Thank you.
回答1:
The addMapPolygon()
method of JMapViewer
works for this, but paintPolygon()
silently rejects a polygon having fewer than three vertices. For a line between two points, just repeat the last Coordinate
.
Coordinate one = new Coordinate(...);
Coordinate two = new Coordinate(...);
List<Coordinate> route = new ArrayList<Coordinate>(Arrays.asList(one, two, two));
map.addMapPolygon(new MapPolygonImpl(route));

I am also working on this software and using the JMapviewer.jar. Yet, I do not seem to have the addMapPolygon nor the MapPolygonImpl ... Is there a specific version I should be working with ? (I downloaded my version here: enter link description here
