[mkgmap-dev] bug in LineClipper (branches/nod)

Thu Nov 27 22:24:28 GMT 2008

Hi,

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  
RoadDef.writeNod2 due to a null RoadDef.node. Since my attempts to  
understand LineClipper.clip failed, I reimplemented it somewhat more  
explicitly, patch attached. I won't be offended if you prefer to fix  
your algorithm; the patch is quite ugly and I'm not really sure it  
works outside my samples.

The resulting maps appear to have some segments missing. Do you think  
this might be caused by clipping?

Cheers
Robert
