Overview

The LaTeX class beamer allows production of high quality presentations using LaTeX and pdf processing. Org-mode has special support for turning an Org-mode file or tree into a beamer presentation.

Example

Here it is an example of how a presentation file should look like

Let's review it by section

  • First you just need to set the basic information about your presentation (title, author, email, date, description and keywords)
  • Then you indicate if you want some extra options in each slide
  • BEAMER_HEADER_EXTRA: include raw LaTeX statements, this is used to define the beamer's theme, in this case we are using the theme Madrid with the default color theme.
  • BEAMERMODE: set the presentation mode in beamer
  • BEAMERINSTITUTE: let you define your college, business, etc.
  • At the end we just write our slides, each level 2 section is a slide.

You can open the file [[file:org-mode.beamer.presentation.org]] in emacs and use the shortcut C-c C-e p to generate a pdf of the presentation. The produced pdf can be downloaded [[file:org-mode.beamer.presentation.pdf][here]]

Setup

Execute the following command in Debian or Ubuntu

sudo apt-get install texlive-extra-utils \
    texlive-binaries \
    latex-beamer \

Add the following to your .emacs file:
