#243 closed enhancement (invalid)
a question about the conversion from Geometry* to Polygon*

Description
I use the following function to get the intersection of two polygons which have holes and the value returned is Geometry *.
geos::precision::EnhancedPrecisionOp:: intersection(Poly_A,Poly_B);
If getGeometryTypeId() tells me the geometry returned is a polygon, how can I get a pointer Polygon * from Geometry * safely ? If I convert it directly, is it always safe ?
Thanks.

Aya,
This is not a bug report, neither a feature request. This is a question that should go on the mailing list.
Please post this and all further questions to the mailing list (subscribe first, if you haven't yet, at geos-devel) and reserve the Trac for bug reports, enhancements proposals or feature requests, but avoid support-like requests or discussions here. Thank you!
Closing.
