Posted - Jun 28 2012 : 09:16:27 Hi @all,
is it possible with TImageEnVect to get the intersection of two polygons?
I need to calculate the area of this intersecting polygon. A workarount would be to merge the two polygons and then subtract this area value from the sum of the single areas.
Is one of these possible? I did not find something in the help nor in this forum.
Thanks a lot! |
