• tools/pdf — generators for the PDF engine's committed encoding data.

This project comes with CMake as a build system and Conan as package manager. In principle they should be independent and one can build without Conan.

Using Conan one can use our Artifactory as a Conan remote for convenience: https://artifactory.opendocument.app/

As an alternative to the Conan remote you can also export the package locally via Conan i.e. conan export . --name odrcore --version VERSION (fill VERSION with something appropriate).

Versions and history are tracked on GitHub.

OpenDocument.core is licensed under the Mozilla Public License 2.0 (MPL-2.0).

Optional build features link the library against third-party components under their own terms — notably pdf2htmlEX (ODR_WITH_PDF2HTMLEX) and wvWare (ODR_WITH_WVWARE), both GPL-licensed. Enabling them and distributing the combined binary may subject the whole to those components' license terms; consult each project's own license before redistributing.

Separately, the committed PDF font/encoding tables in src/odr/internal/pdf/ are generated from third-party source data whose provenance and terms are documented in tools/pdf/THIRD_PARTY_LICENSES.md.
