I found a very neat beamer theme (Arguelles, https://github.com/piazzai/arguelles) however there are three things that I believe are troublesome with the theme. I am trying to improve them but I am finding myself short of the required knowledge in the beamer class and LaTeX in general. Any help would be greatly appreciated.

This question is about circumventing the use of TikZ to define every frame's background. The background of each slide is defined using a TikZ picture, recomputed for every slide. This is not bothering for short presentations with few other TikZ figures, but it becomes quite a problem once one tries to write long presentations with many TikZ figures, where the use of the TikZ library externalize would be beneficial. Again, I can circumvent this by replacing lines 62-69 of beamerinnerthemeArguelles.sty by \setbeamercolor{background canvas}{bg=structure.bg}, but it removes the bottom black bar and seems to break other things such as standout slides. The question is then: how to rewrite the background specification in beamerinnerthemeArguelles.sty so that it produces the same output, without using TikZ.

Instead of using a dark background colour and then overpaint all frames with tikz, I would use a light colour and add the small black stripe as a footline:

\documentclass{beamer}

\usetheme{Arguelles}

\setbeamercolor{background canvas}{bg=structure.bg}

\setbeamertemplate{footline}{%
  \color{structure.fg}%
  \rule{\paperwidth}{.01\paperheight}
}

\makeatletter
\def\ps@navigation@titlepage{%
  \setbeamercolor{background canvas}{bg=structure.fg}
  \@nameuse{ps@navigation}}
\addtobeamertemplate{title page}{\thispagestyle{navigation@titlepage}}{}

% standout frame
\define@key{beamerframe}{standout}[true]{
 \booltrue{Arguelles@standout}
 \begingroup
 \setbeamercolor{background canvas}{bg=structure.fg}
 \beamer@frametopskip=0pt plus 1fill\relax%
 \beamer@framebottomskip=0pt plus 1.25fill\relax%
 \color{structure.bg}
 \large
}
\makeatother


\begin{document}

\begin{frame}
\titlepage
\end{frame}

\begin{frame}[standout]
test
\end{frame}

\begin{frame}
  text
\end{frame}

\end{document}

  • That makes much more sense indeed, but for some reason it makes a complete blank slide for the title slide (when using the plain option) and the standout slides are "normal slides" with no text. Did you also modify the inner theme?

    You need to remove the tikz stuff: %% background %\BeforeBeginEnvironment{frame}{ % \setbeamertemplate{background}{ % \begin{tikzpicture} % \useasboundingbox (0,0) rectangle (\paperwidth,\paperheight); % \ifnum\thepage>1\relax % \fill[structure.bg] (0,.01\paperheight) rectangle (\paperwidth,.99\paperheight); % \fi % \end{tikzpicture} % } %}

  • Ah I see. Then there is one last caveat. The title page should not have a progress bar. The way this was done before was by calling \frame[plain]{\titlepage}. If I do that I get a blank page. I could call \frame{\titlepage}, but then it shows the progress bar.

  • I have found a way to remove it using \setbeamertemplate{headline}{} for the whole title frame. It feels hack-ish but it works.
