How can I interesect an Iso_rectangle_2 and Segment_2 using CGAL::intersection() ? I get a lot of errors regarding its definition. I believe the most rellevant is:

Iso_rectangle_2 is not a member of CGAL::Projection_traits_xy_3<K>

At the intersection line I get the error:

cannot convert from 'const CGAL::Iso_rectangle_2<portho::cgal_utils::Gt>' to 'const CGAL::Bbox_3'

The Segment_2 comes from a CGAL::Polygon_2<Gt>::Segment_2.

I've tried defining Iso_rectangle_2 as

CGAL::Iso_rectangle_2<Gt> as well as Gt::Iso_rectangle_2

CGAL::intersect() documentation says Iso_rectangle_2 and Segment_2 are accepted.

If I can't figure it out I'll just create a copy of the segment and the iso rectangle based on K instead of Gt
