Recent policy changes in the United States and the European Union request that +course materials be delivered as tagged, accessible PDFs. LaTeX Beamer is not compatible +with these requirements, but ltx-talk, a modern LuaLaTeX package based on Beamer can +produce fully tagged PDFs. + +We describe the process that brought ltx-talk export support to Org mode. We then show +some of the features of the export backend and ltx-talk, and the current limitations. +Because ltx-talk is relatively new and under development itself, we conclude with a call +for help to further improve Org's support of accessible PDFs on ox-beamer (and, why not, +ox-latex) and ensure future compatibility and feature completeness. + +About the speaker: + +Pedro A. Aranda (he), currently maintaining ox-latex and ox-beamer in +Org mode. I came from LaTeX + Emacs to Org mode and have been using ox-beamer +and ox-latex for a long time and wanted to give back. After some patches, and +a lo of patience to get better font configuration for LuaLaTeX, I felt +I could go ahead and take care of them. I'm in the process of switching to +ltx-talk for my presentations using ox-beamer. + + + +[[!inline pages="internal(2026/info/ltx-talk-after)" raw="yes"]] + +[[!inline pages="internal(2026/info/ltx-talk-nav)" raw="yes"]] + + |
