My question is in a sense the reverse of this question on overlays. Here's what I'd like to do.

I have a beamer presentation that includes two frames, each with some overlays. Each frame looks like

\begin{frame}
\includegraphics<1>{fig1}
\includegraphics<2>{fig2}
....
\end{frame}

Suppose I have 3 overlays in each frame. Then my output PDF has 6 pages and even if I don't render page numbers in my style, I can see the page numbers in the viewer.

What I'd like instead to have happen is that the pages are numbered X-Y in the final PDF, so that in my PDF viewer, I see "1-1, 1-2, 1-3, 2-1, 2-2, 2-3" instead of 1-6.

Note that this may be independent of whether I choose to render the page numbers in a beamer style (I'm not sure if it is).

My reason is that I want a better way to calibrate the "number of slides" that my talk has, and overlays shouldn't really count (because they animate quickly)

Update: Here's an example of what I'd see in the viewer:

  • At its heart, this seems to be asking for custom page numbers in the PDF to be displayed in the viewer (ie not (just) typeset on the page). Am I right? If so, there are two parts: customising the PDF page numbers and getting beamer to put the A-B part in there. The first of these is not beamer related and, without investigation, for me looks the harder task. Do you know if it is possible? If not, and my interpretation is right, you might want to consider splitting this into two questions accordingly.

  • You may be right. I know this is possible because when I generate views in ipe, I can get this effect. Since Ipe uses latex to generate the final output, I assumed that it's a tex trick. Specifically, using the "create page" feature in ipe to make a multipage pdf, and the 'create view" to create overlays, I can get this.

The PDF page labels are added by beamer via \thispagelabel{\insertframenumber}. Because hyperref uses \pdfstringdef to convert the page label to a PDF string, its methods, \pdfstringdefDisableCommands can be used to change \insertframenumber for the page labels. I have not found a counter for the overlays, the only useful thing was the page number \beamer@framestartpage, when the frame starts. That at least allows the calculation of the overlay number.

\listfiles
\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage{lmodern}

\pdfstringdefDisableCommands{%
  \renewcommand*{\insertframenumber}{%
    \theframenumber-%
    \the\numexpr\value{page}-\beamer@framestartpage+1\relax
  }%
}

\begin{document}

\begin{frame}
\fontsize{20mm}{30mm}\selectfont\bfseries
1st frame,\\
\only<1>{1st overlay}
\only<2>{2nd overlay}
\only<3>{3rd overlay}
\end{frame}

\begin{frame}
\fontsize{20mm}{30mm}\selectfont\bfseries
2nd frame,\\
\only<1>{1st overlay}
\only<2>{2nd overlay}
\only<3>{3rd overlay}
\end{frame}

\end{document}

  • No, it does not change the page numbers, but the page labels. A PDF page label is a string that tells the PDF viewer, how the page should be labeled.

  • @AndrewStacey: Unfortunately \the\beamer@slideinframe will not help here, the values are not correct, increased by one except for the last slide in a frame.
    – Heiko Oberdiek
    Aug 22, 2012 at 10:35
  • From a glance at the code, my guess is that \beamer@slideinframe gets incremented after the frame content is read but before it gets written out, whence when \insertframenumber is used then it actually is at the next setting, except for the last frame as that skips the incrementation step.
