Hi all! Is it possible to render point layer as line layer? In my situation, all points have "time" attribute (which impose order on the set of point), and I would like to draw line between p1 and p2, when time(p1) 'strictly less' then time(p2), i.e. there are no point p3 between them, such that time(p1)<time(p3)<time(p2). Of course, I can use  org.geotools.swing.event.MapPaneListener,
and by redefining method onRenderingStopped I can analyze my layer, sort points by time, and then 'connect the dots'. Downside of this approach is performance and memory degradation, since I need to keep in memory entire set of points for some time (when sorting them and rendering). What can I do? Maybe some out-of-the-box solution exists? Thanks, Sergey |
