lib2geom v1.1.0

2Geom v1.1 is not ABI compatible with v1.0, it switches from boost::optional to std::optional.

Changes:

  • Add Geom::Parallelogram
  • Add Geom::PathIteratorSink::inPath()
  • Add Geom::are_near_rel() for Geom::Point
  • Move headers to include directory
  • Make build system git submodule friendly
  • Fix Python 3 support (py2geom)
  • Remove Python 2 support (py2geom)

lib2geom v1.0.0

2geom is a C++ library of mathematics for paths, curves, and other geometric calculations, designed to be well suited for vector graphics: Bézier curves, conics, paths, intersections, transformations, and basic geometries.

Originally developed to restructure and improve path data structures in Inkscape, this library's codebase has been maintained and shipped as part of the professional vector graphics software for over a decade.

The major contributors to the 2geom library are Nathan Hurst, Michael G. Sloan, Krzysztof Kosiński, Johan B. C. Engelen, MenTaLguY, Aaron Spike, Marco Cechetti and JF Barraud.

Work on this release has focused on updating the 2geom source control, build, test and packaging systems for both Linux and Windows. The py2geom python extension package has been restored and improvements have been made to overall code stabilization and quality.

The primary motivation for 2geom's 1.0 release is to support a future Inkscape 1.0 launch.

With this evolution to a distinct package, the 2geom team is seeking new opportunities to collaborate with individuals and projects interested in using this proven tool.
