Thanks for the help!

Hi Mateus,

You have encountered a bug (or perhaps two) in the exporter and importer of polycurves.

The relevant code resides in include/CGAL/Arr_geometry_traits/Polycurve_2.h

Attached is a patch, so that you can fix the code immediately.

The next release of CGAL will include the fix.

Thank you,

Efi

I'm not sure about that: the kernel is the CGAL::Cartesian<Number_type> ?

I'm sending the .cpp and CMakeLists attached.

Thank you

What kernel are you using?
Please provide a complete example we can compile and run.

Sebastien.

Hello

I'm trying to use the I/O functions to write and read an arrangement to
a file. The problem is that when I try to read the arrangement from the
file the program get stucked. I'm using a very simple program to test
and I already checked the file generated by write and it is not empty.
My .cpp code:

   Arrangement_2 arr1,arr2;
   Point_2 p1 (1 , 3 ) , p2 (3 , 5 ) ;
   XSegment_2 s1 (p1 , p2 ) ;

   Arrangement_2::Halfedge_handle e1 = arr1.insert_in_face_interior( s1
,arr1.unbounded_face( ) ) ;
   Vertex_handle v1 = e1->source();

   ofstream out_file("arr_ex_io.dat");
   out_file << arr1;
   out_file.close();


   ifstream in_file("arr_ex_io.dat");
   in_file >> arr2;
   in_file.close();


Anyone had the same problem? Thanks in advance
