Hi I am just about to commit a merge the work from trunk into nod which I hope doesn't confuse things too much. Sorry if it does.
there seems to be something wrong in LineClipper.clip -- it seems to create a bunch of zero-node roads, which then cause a crash in
OK, I havn't looked at your patch fully yet, but I see a problem. MapRoad is a sublass of MapLine, but if one is clipped, then it is copied as if it were a MapLine. Therefore it will not get a roadId or a roadDef set.
The resulting maps appear to have some segments missing. Do you think this might be caused by clipping?
Perhaps, but nothing should be clipped, should it? There may be a bug where more is being clipped than should be. This was recently the case with polygons and a similar bug caused all polygons to be invisible. Cheers, ..Steve
