beamer's Introduction

Beamer - A LaTeX class for producing presentations

Overview

The beamer class is focused on producing (on-screen) presentations, along with support material such as handouts and speaker notes. Content is created in a frame environment, each of which can be divided up into a number of slides (actual output pages). A simple 'action' notation is used to specify which material appears on each slide within a frame. The class supports a range of environments to enable complex slide relationships to be constructed.

The appearance of slides is controlled by a template system. Many of the elements of slides can be adjusted by setting simple key-based values in the preamble. More complex changes can be implemented by altering specific, targeted definitions without needing to rewrite entire blocks of code. This allows a variety of visual appearances to be selected for the same content source.

License

The beamer class is made available under the LaTeX Project Public License (LPPL) and the GNU Public License (GPL). See the information in LICENSE for information on licensing.

beamer's Issues

blocks with [default] corners not placed properly in columns env

Originally reported by: Jürg Treichler (Bitbucket: juergtr, GitHub: Unknown)


Hi,

I came across an issue with blocks using the default (i.e. not rounded) corners. When such a block is placed inside a column, the whole column gets shifted to the left. The block does no longer properly align to a block outside of the columns env (see attached test case).

I believe that the strange behavior originates in the code for beamercolorbox in beamerbasecolor.sty:

When I change (around line 210)
#\else%
#\if@tempswa\setbox\beamer@tempbox=\vbox{%
#\usebeamercolor{\beamer@colbox@color}%

to
#\else%
#\if@tempswa\setbox\beamer@tempbox=\hbox{%
#\usebeamercolor{\beamer@colbox@color}%

(\vbox to \hbox), everything seems ok.

Do you believe that this fix is ok, or do I mess up anything else?

Thx
Jürg


Accented math operators do not work with T1 and beamer (beamer-specific)

In spanish, you write, for instance, m\'aximo'', and l'imite'', and the corresponding math operators max and lim (with backslash, of course) automatically put the accent. But you get horrible results with beamer if you use T1 encoding:

\[
  \max\{ 2, 3 \} = 3.

\[
  \lim_{n \to \infty} \frac1n = 0
\]

They works properly without T1 enconding or without beamer.

Add a template for the contents of the sidebar

Originally reported by: Anonymous


The contents of the sidebar "header" (title and author) seem to be hardcoded in
\defbeamertemplate*{sidebar \beamer@sidebarside}{sidebar theme}{...}
in beamerouterthemesidebar.sty.
It would be useful to have a template for this so that you can re-define it without having to redefine the whole thing. The sections and subsections are fine, but in my case I would like to add the lecture title, and I could imagine wanting to add the date or other things in there.


\footnote[frame]{} wraps text at column width

Originally reported by: idleroux (Bitbucket: idleroux, GitHub: Unknown)


A footnote in a frame with columns, gets wrapped at the width of the first column, even when the [frame] option is used to make the footnote frame-global. I can prevent the undesired wrapping by putting the footnote in an \mbox, but that seems like an unnecessarily ugly hack.

Simple example:

\documentclass{beamer}
\begin{document}
\begin{frame}
  \begin{columns}
  \column{0.5\textwidth}
  Column text
  \column{0.5\textwidth}
  More column text\footnote[frame]{This footnote gets wrapped at the column width.}
  \end{columns}
\end{frame}

\begin{frame}
  Frame text.

  More frame text\footnote[frame]{This footnote, on the other hand,
  gets the full frame width.}
\end{frame}
\end{document}

Merge translator into beamer

Originally reported by: Vedran Miletić (Bitbucket: rivanvx, GitHub: Unknown)


Since translator has so far only supported strings that Beamer required, and since it would make it easier to maintain both if there was just one package instead of two, the goal is to make Translator a part of Beamer in an intelligent way.

This will (hopefully) make translator a lot more popular, and once we write a section of beameruserguide that talks about translating, it will make it easier to reach people who are willing to contribute translations.

This must not stop other packages from using translator without beamer, if they wish to.


problem with subsubsection code

Originally reported by: ax006ho (Bitbucket: ax006ho, GitHub: ax006ho)


I'm not sure but I think, that there is a problem in the subsubsection code in file beamerbasetoc.sty (beamer 2010) in line 186, column 126: where is a \if for that \else?

My presentation, which compiled fine under beamer 2009, runs into an error at that point. For a deeper investigation of that error I created a smaller test and a shell script. The test compiles under beamer 2009, but not under beamer 2010. I attach the two files.


Old CTAN repository

Hi guys,

I appreciate people spending their spare time on developing something that is useful to others but why (on earth) was the CTAN repository with the old beamer class files taken down before the new version is finished?

Blocks and itemize: incompatibility?

Originally reported by: Anonymous


I discovered the problem while trying to use blocks as containers/frames for images: the title works as caption.

If I have only blocks in the page, I can make them appear using the notation, but if I also have an itemize environment in the page, they don't work anymore: when using "transparent" they appear according to the specifications, but they are transparent until the last step of the slide.

Examples are given here, where I asked before making further tests and finding it could be a bug of beamer:

Beamer and Geometry

Originally reported by: ben122684 (Bitbucket: ben122684, GitHub: Unknown)


Hi. There is a new Geometry package out and it seems to conflict with the latest Beamer package; i.e., Beamer files will not compile when using the latest Geometry package, but will compile when reverting back to an older version. I have sent an email to the maintainers of the Geometry package without a response. Here is the email I sent to them.

"Hi. This may be a documented problem already, but I am having an issue trying to use the latest version of the Geometry package with Beamer. I am using

This error no longer occurs when I revert back to the previous version of the Geometry package."


textblock and \setbeameroption{show notes on second screen}

Hi,

I may have found a bug when using textblock and \setbeameroption{show notes on second screen}

== Normal case ==
Here is a simple example : two frames. There is a textblock on the second.

\documentclass{beamer}
\usepackage[latin1]{inputenc}
\usepackage[absolute,overlay]{textpos}

\begin{document}

	\begin{frame}
		Frame 1
	\end{frame}

	\begin{frame}
		Frame 2
		\begin{textblock}{5}[0,0](5,5)
			Mon textblock
		\end{textblock}
	\end{frame}

\end{document}

Here every thing is okay. The textblock appears on the second slide.

== The bug ==

Then, I want to display the notes with \setbeameroption{show notes on second screen}

\documentclass{beamer}
\usepackage[latin1]{inputenc}
\usepackage[absolute,overlay]{textpos}

\usepackage{pgfpages}
\setbeameroption{show notes on second screen=right}

Stop frame numbering after a slide

Originally reported by: Anonymous


Hi,

(Re-submitting SourceForge feature request. Not //that// important, but I'd appreciate having this in Beamer)

I have a presentation with, say, 47 slides, and 3
"backup slides" that I'll use only if I get questions
about them.

Currently, the last slide is numbered 47/50 (and the
backup slides are 48/50, 49/50 and 50/50). So, when I
show the presentation, the public still expects
something at the end.

I have a dirty hack:

\newcommand{\noframenumber}%
{\makeatletter\global\advance\c@framenumber
by-1\relax\makeatother}

and the presentation ends with

\noframenumber
\begin{frame}
  \frametitle{Backup slides}
  
\end{frame}

\noframenumber
\begin{frame}
...
\end{frame}

But I'd like something cleaner, like
"\stopframenumbering", "\backupslides" or perhaps
"\appendix".

Another option would be to allow

\begin{frame}[nonumber]
...
\end{frame}

How to invoke short section name

Originally reported by: said (Bitbucket: said, GitHub: said)


In beamer we can defined section as

\section< mode specification >[ short section name ]{ section name }

I want to invoke the "short section name" in the frame title.
As I know, \secname can invoke the " section name", \subsecname the "subsection name" and \lastsubsection the "short subsection name". However, I didn't find a method for invoking the "short section name".

Any suggestion is appreciate.


beamercolorbox: unexpected behavior

Originally reported by: Nico Schlömer (Bitbucket: nschloe, GitHub: nschloe)


Hi,

not really sure if this is a bug or not, but the behavior is somewhat unexpected to me: When invoking

\begin{beamercolorbox}[leftskip=1cm,right]{}
[...]
\end{beamercolorbox}

the leftskip is entirely ignored. When doing

\begin{beamercolorbox}[right,leftskip=1cm]{}
[...]
\end{beamercolorbox}

the text [...] is not set flush right.

Cheers,
Nico


Documentation: incorrect new paragraph start

Originally reported by: Daniel Arteaga (Bitbucket: darteaga, GitHub: darteaga)


Hi,

The documentation there are several instances of new paragraphs (i.e, double blank space lines) openening right after verbatim statements in places where you wouldn't expect a new paragraph.

I attach a patch with several of those instances fixed.

I profit the ocasion to congratulate Vedran for the new life to the fantastic Beamer project!

Best regards,

Horizontal shading in sidebar

Originally reported by: hakante (Bitbucket: hakante, GitHub: hakante)


Hi,

I wanted to create a horizontal shading in the sidebar, but there seems to be a small bug in that code.

Consider the file <<file 25c1d2087065:beamer/base/beamerbasecompatibility.sty#L399>>

The lines

\newcommand{\beamertemplatesidebarhorizontalshading}[3][left]{%
  \setbeamertemplate{sidebar canvas #1}[vertical shading][right=#3,left=#2]}

should be

\newcommand{\beamertemplatesidebarhorizontalshading}[3][left]{%
  \setbeamertemplate{sidebar canvas #1}[horizontal shading][right=#3,left=#2]}

beamer user guide doesn't compile correctly

Originally reported by: Anonymous


I have MiKTeX 2.8 running on 64-bit Windows 7. The most recent versions of beamer, pgf, and xcolor are installed.

I wanted to look at documentation. So, I downloaded the beamer distribution 3.09 and tried to compile the file

\beamer\doc\beameruserguide.tex

The document will compile but will not include any of the graphics. In places where there should be graphics in the pdf output, there is a box containing the words "pgflastimage1" or "pgflastimage2".

I tried this on three different computers on which MiKTeX was correctly installed and on which other beamer slide presentations correctly compile.


corrections and wishes

Originally reported by: ax006ho (Bitbucket: ax006ho, GitHub: ax006ho)


  • On page 14 (Fedora) there is a text "aptitude install..."
    It must be changed into "yum install ..."
  • On pages 16 and 18 there is mentioned the command \defverbatim, but in the complete manual you can't read any documentation of that command. Could you provide a small documentation and an example for that command in beameruserguide?

enumerate vs. beamerarticle

Originally reported by: akim (Bitbucket: akim, GitHub: akim)


Hi all,

Thanks for making beamer live again, it's one of the most beautiful existing tools.

First, a small grief: I download the zip, and I can't make use of it, because it's full to $Header$, which, apparently, cause plenty of parse errors. I had to comment out a couple of lines involving \beamer@parseid to get it to work.

Now to the point.

The enumerate package seems to be very well supported in the beamer class, but it does not work at all in the beamerarticle mode. This is a pity. The doc does mention that you have to usepackage enumerate yourself, but it makes no difference. The following example shows that it does not work. Remove the beamerarticle use to see what the expected output is.

Cheers!

Page numbers when using \addcontentsline

Originally reported by: Anonymous


Hi, I'm so happy to see a new maintainer has been found that I want to enter this seemingly minor issue here. I had posted about it on comp.text.tex but never really reported it as a bug.

In presentations, usually, the outline at the beginning does not contain page numbers as a table of contents in an article does. However, when using `addcontentsline{toc}{...}{...}` directly to add a comment to the outline, the frame number is added to the end of the added material.

Specifying
\renewcommand\addcontentsline[3]{\addtocontents{#1}{\protect\contentsline{#2}{#3}
in the document fixes this, but it really should be fixed in the package, unless maybe you are not supposed to use addcontentsline in beamer at all (is there a beamer command for this which I missed in the docs?)


Beamer supports LuaLaTeX and XeLaTeX, but it's not documented

Originally reported by: Vedran Miletić (Bitbucket: rivanvx, GitHub: Unknown)


Since Beamer was mostly developed in time before LuaLaTeX existed and before XeLaTeX was a popular choice (and likely before it was included in TeX Live), Till didn't consider necessary to discuss Beamer's compatibility with both. But now, instead of two (latex+dvips+ps2pdf and pdflatex), we have four engines.

However, they both work and that should be documented. TikZ/PGF manual is better in this regard, even it doesn't mention LuaLaTeX for same reasons.


Header/footer and vertical centering of the body text

Originally reported by: Nico Schlömer (Bitbucket: nschloe, GitHub: nschloe)


Hi,

when putting a, say, 3cm high image at the footer of each page, the body text still gets vertically centered in the middle of the page. It should however be vertically centered between the top and 3cm above the bottom line.

Not sure if there's any way already to tell beamer about the vertical centering manually somehow.

Cheers,

Issu with background image/color get darker and alpha channel

Originally reported by: Anonymous


Hi,
While making my beamer presentation, I noticed that my background image (a png) get darker when:

  • an image is included
  • block are used with shadow
    I observed the same problem with a gradient instead of the background image.

After some investigations, I found that adding an alpha channel to my image fixed the problem with block. Also, adding an alpha channel to the included image helps.

I don't think this is a bug, but maybe it would be nice to tell about this issue into the documentation. Also, maybe a warning message at compile time could help.

I use beamer since years and it's a great tool: thanks a lot.

beamer should generate pdf page labels using hyperref

Originally reported by: Chung-chieh Shan (Bitbucket: ccshan, GitHub: ccshan)


Hello,

hyperref version 6.75p disables pdfpagelabels if \thepage is undefined when hyperref is loaded, which is the case when the first line of the document is \documentclass{beamer}. Instead, beamer should (1) define \thepage earlier so that hyperref enables pdfpagelabels; (2) use the \thispdfpagelabel macro (introduced in hyperref version 6.71f) to set the pdf page label on every frame. Currently, I achieve these effects by saying

\pagenumbering{arabic}
\documentclass{beamer}
\mode<presentation>{\setbeamertemplate{sidebar left}{\thispdfpagelabel{\insertframenumber`

in my presentation document. The page labels are useful because they ease navigation in PDF viewers such as Acrobat Reader and pspresent (the latter in conjunction with the next version of pdftops from poppler).

Thank you!


Text is justified in overlayarea

Originally reported by: Manuel Pégourié-Gonnard (Bitbucket: mpg, GitHub: mpg)


Hi,

Text is justified in an overlayarea environment, while it is usually flushed left. This does not seem to happen with overprint, though I remember it did with previous versions of beamer.

Here is a reproducer, with beamer 3.07:

\documentclass{beamer}
\usepackage[ascii]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lipsum}

\begin{document}

\begin{frame}{normal}
\lipsum[1]
\end{frame}

\begin{frame}{overlayarea}
  \begin{overlayarea}{\textwidth}{13\baselineskip}
    \lipsum[1]
  \end{overlayarea}
\end{frame}

\begin{frame}{overprint}
  \begin{overprint}
    \lipsum[1]
  \end{overprint}
\end{frame}

\end{document}

This is a bit surprising and slightly annoying, though easily worked around by placing a \raggedright command inside each overlayarea environment.

Thanks,
Manuel.

support for several logos

Originally reported by: Nico Schlömer (Bitbucket: nschloe, GitHub: nschloe)


Right now it's possible to only include exactly one logo into a beamer presentation template.
In reality, people often use several logos, e.g., the one of their university, of the project they're sponsored by, and so forth. Also, one institution might have several logos to be placed, e.g., an actual logo at the top and some sort of mission statement at the bottom of the page.

I believe it would enhance beamer to have support for this.

Latex Beamer Problem with footnote author()

i think this a small thing to change but i have no idea where:

when i compile using beamer with the boadila theme, in the footnote on every slide it appears my name followed by (). In some other cases with different theme it does not. It seems to be in the same way as on the following pages on Sebastian Franks Site:

Boadila: http://www.namsu.de/latex/themes/Boadilla-Titel.html

Malmoe: http://www.namsu.de/latex/themes/Malmoe-Titel.html

Perhaps one knows what to change...

More slide thumbnails in notes

Originally reported by: michaelaoash (Bitbucket: michaelaoash, GitHub: michaelaoash)


This request would apply to material on page 176 of the User Guide v. 3.06.

I love giving talks with the notes on the second screen. It's one of the best of latex-beamer's many excellent features.

It would be neat to be able to see thumbnails of the current slide, next slide, and perhaps the previous slide at the top of the notes on the second screen. In the current version, the notes screen displays a thumbnail of the current slide, but it would be really nice if the default were to display thumbnails of the current slide and the next slide.

An alternative would be to modify \insertslideintonotes so that it is possible to specify an arbitrary slide number.

This would be very helpful because it could cue remarks such as, "On the next slide I will show you..."


Add release tarballs to the uploaded files section

Originally reported by: Tim Harder (Bitbucket: radhermit, GitHub: radhermit)


It would be great to add versioned archives available of the newer releases (3.08, 3.09, ...) under the Uploaded files section of the Downloads area.

In addition, it would be nice to have the archives and directory names follow the standard format used previously on the older sourceforge releases. For example, using an archive name of latex-beamer-3.07.tar.gz with the top-level directory name being latex-beamer-3.07. Basically, PN-PV.tar.gz where PN is the package name and PV is the package version with a top-level directory name of PN-PV. Currently the tagged archive checkouts don't follow this standard as well.

Trying to add shading to frametitle.

Originally reported by: mattbellis (Bitbucket: mattbellis, GitHub: mattbellis)


Hi all,

This is more a general question for the beamer community than a bug (I think).

I'm trying to add the color fading that used in the Singapore theme for the head to a different section of a frame. I don't use a head, but I'd like to use that effect for the frametitle for my own .sty.

The easiest way to show you what I'm trying to do is for you to add these lines to the end of the Copenhagen theme. The end of beamerthemeCopenhagen.sty then looks like this for me.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Added this
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\AtBeginDocument{%
    {
     \usebeamercolor{frametitle}
    }
    \pgfdeclareverticalshading{beamer@frametitlefade}{\paperwidth}
    {%
     color(0.0cm)=(bg);
     color(1.00cm)=(frametitle.bg)%
    }
    \setbeamercolor{frametitle}{bg=}
}
\addtobeamertemplate{frametitle}{\pgfuseshading{beamer@frametitlefade}\vskip-1.15cm}{}
\beamertemplatedotitem


\mode
<all>

I admit I kind of hacked it together after reading the user guide and trying to understand what was happening in the Singapore theme. My Latex compiles and I get the fading effect but there's a blank white space on the left of the frame title about an inch or so wide. I've been trying to find out where that's coming from, but no luck.

The fading looks pretty good if I could just get this last part swinging! Any help is greatly appreciated.

Beamer is awesome. :)

Make Beamer able to generate asymetric two-screen presentations

Originally reported by: Vedran Miletić (Bitbucket: rivanvx, GitHub: Unknown)


From Stanislaw Polak:

"I use the \setbeameroption{show notes on second screen=left} option to divide a slide into two equal size parts / rectangles (left part with notes and right part with a content). I use the "Impress!ve" application, under Linux, to display my presentation. Because my laptop has possibility to use an extended desktop, Impress!ve displays the left part (the notes) on my laptop's screen and the right part (the content) on a projector. Presentation is displayed properly if both the laptop and the projector use the same resolution. If they use two different resolutions, a fragment of other part is visible, i.e., students see the whole content of a slide and a fragment of the part with notes. I have a proposition - a new option should be added to the Beamer class. Thanks to this option, a user could set that the left part will be displayed in 1680x1050 while the right part in 1024x768, and the Beamer class should divide the slide into two proportional parts (different size of rectangles (parts), different size of fonts, ...)"


(x)dvipdfmx produces annotation out of page boundary warnings on Beamer presentations

Originally reported by: Vedran Miletić (Bitbucket: rivanvx, GitHub: Unknown)


When compiling Beamer presentations with XeLaTeX, there are usually lots of errors:

** WARNING ** Annotation out of page boundary.
** WARNING ** Current page's MediaBox: [0 0 362.835 272.126]
** WARNING ** Annotation: [8.50402 263.614 58.7396 272.389]
** WARNING ** Maybe incorrect paper size specified.

XeTeX mailing list thread [1] discusses the issue, but without any real solution and with an example that isn't so useful (since it actually goes out of page boundary).

However, I can reproduce the same issue with Antibes theme, and (somewhat strangely) it doesn't happen without fontspec and xltxtra packages. It should be investigated:

what exactly is out of page boundary and gest cropped, and

why does fontspec and xltxtra affect that.

This is a nontrivial task, so it will be left for a future release, unless, of course, an XeTeX expert randomly stumbles upon this and decides to fix it.

Wrong section numbering qith \section in groups.

Originally reported by: Manuel Pégourié-Gonnard (Bitbucket: mpg, GitHub: mpg)


Hi,

When a \section command appears inside an group (e.g. inside an environment), the section numbers in the table of contents are wrong. The reason is, \beamer@section increments \beamer@tocsectionnumber using \advance without a \global prefix.

Using \section inside a group may sound weird, but is quite natural when preparing alternative version using the comment package. Here is a reproducer, tested with beamer 3.07:

\documentclass{beamer}
\usepackage[ascii]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{verbatim}
\newenvironment{fr}{\comment}{\endcomment}
\newenvironment{en}{}{}

\useinnertheme{rounded}

\begin{document}

\frame{\tableofcontents}

\begin{en}
  \section{Beamer is cool}
\end{en}
\begin{fr}
  \section{Beamer, c'est bien}
\end{fr}
\frame{blabla}

\begin{en}
  \section{Beamer is really cool}
\end{en}
\begin{fr}
  \section{Beamer, c'est vraiment bien}
\end{fr}
\frame{blabla}

\end{document}

Thanks,
Manuel.

article mode: \titlepage resets page counter

Originally reported by: Vedran Miletić (Bitbucket: rivanvx, GitHub: Unknown)


A new frame with \titlepage will reset the page count to 1 in article mode (probably in all modes but truly a problem in article mode).

It is a minor problem, given that a simple workaround is to wrap this behaviour in some macro and make it mode sensitive, but it took a while to find out the problem.

A quick fix would simply be to have a message that indicates page count is reset, such that one can look into the log and quickly understand the problem, and save some time fooling around!
