Getting started

dxfio is a static library that needs nothing but the standard library; the tests and doctest are built only when dxfio is the top level project.

dxfio/dxfio.hpp brings in the whole interface, under the namespace DxfIO. This program makes a drawing with one line, saves it, and reads it back. Nothing throws: a load or a save that fails returns its Failure, with what went wrong and, for a load, on which line.

  DxfIO::Document drawing = DxfIO::Create(DxfIO::Version::R2018);

  line.End = {.X = 100, .Y = 50, .Z = 0};
  DxfIO::Edit::Add(drawing, line);

  const auto saved = DxfIO::SaveFile(drawing, "first.dxf");
  if (!saved)
  {
    std::println("{}", saved.error().What);
    return 1;
  }

  const auto loaded = DxfIO::LoadFile("first.dxf");
  if (!loaded)
  {
    std::println("line {}: {}", loaded.error().Line, loaded.error().What);
    return 1;
  }
  std::println("{} entity, {} issues", loaded->Document.Entities.size(),
               loaded->Issues.size());
