[mkgmap-dev] [mp: PATCH] Multipolygons: inner and nested polygons supported now

Sat Jan 2 09:26:02 GMT 2010

Thanks for committing the new multipolygon to a branch and for all of 
your comments. They're helpful always!

I have improved the multipolygon handling in the mp-branch.

Changes:
* Tagged inner polygons are supported now
* Nested polygons (outer in inner in outer etc) are supported now
* Bugfix in the findCpa method (this could also be interesting for the 
trunk). findCpa did search only for the two closest points. It didn't 
check if this connection intersects the outer polygon. The bugfix checks 
this (see attached picture: old version selects the red line, bugfix 
selects the green line).

Next thing to do is to bugfix the PolygonSplitter.

Comments are welcome!
