Graphics created using AlDraTex must be treated like verbatim text. The reason is that DraTex fiddles with catcodes and spaces much like verbatim does. So, in order to insert a picture, either add the fragile option to the frame or use the \defverbatim command to create a box containing the picture.

Text in an alltt environment must be treated like verbatim text. So add the fragile option to frames containing this environment or use \defverbatim.

This package is automatically loaded since beamer uses it for typesetting theorems. If you do not wish it to be loaded, which can be necessary especially in article mode if the package is incompatible with the document class, you can use the class option noamsthm to suppress its loading. See Section 12.4 for more details.

When using the french style, certain features that clash with the functionality of the beamer class will be turned off. For example, enumerations are still produced the way the theme dictates, not the way the french style does.

When using the spanish style, certain features that clash with the functionality of the beamer class will be turned off. In particular, the special behavior of the pointed brackets < and > is deactivated.

To make the characters < and > active in article mode, pass the option activeospeccharacters to the package beamerbasearticle. This will lead to problems with overlay specifications.

The color package is automatically loaded by beamer.cls. This makes it impossible to pass options to color in the preamble of your document in the normal manner. To pass a ⟨list of options⟩ to color, you can use the following class option:

The color package is not loaded automatically if beamerarticle is loaded with the noxcolor option.

With newer versions of xcolor.sty, you need to pass the option table to xcolor.sty if you wish to use colortbl. See the notes on xcolor below, on how to do this.

When using the CJK package for using Asian fonts, you must use the class option CJK.

The caption generation facilities of deluxetable are deactivated. Instead, the caption template is used.

See AlDraTex.

This package is loaded automatically in the presentation modes, but not in the article mode. If you use its features, you have to load the package “by hand” in the article mode.

Use the T1 option only with fonts that have outline fonts available in the T1 encoding like times or the lmodern fonts. In a standard installation standard Computer Modern fonts (the fonts Donald Knuth originally designed and which are used by default) are not available in the T1 encoding. Using this option with them will result in very poor rendering of your presentation when viewed with pdf viewer applications like Acrobat, xpdf, evince or okular. To use the Computer Modern fonts with the T1 encoding, make sure you have installed cm-super package in your TeX distribution, or use Latin Modern fonts provided by lmorden instead. See also Section 18.2.3. This applies both to latex+dvips and pdflatex.

The newest version of LaTeX2ε kernel has introduced TU encoding for xelatex and lualatex. Note that xelatex and lualatex support OpenType fonts, and font encodings work very different compared to pdflatex. Again, see Section 18.2.3 for more information.

The package switches to a T1 encoding, but it does not redefine all fonts such that outline fonts (non-bitmapped fonts) are used by default. For example, the sans-serif text and the typewriter text are not replaced. To use outline fonts for these, write \usepackage{lmodern} before including the fourier package.

You cannot use this package with beamer. However, you might try to use the package beamerprosper instead, see Section 24.1.

The hyperref package is automatically loaded by beamer.cls and certain options are set up. In order to pass additional options to hyperref or to override options, you can use the following class option:

Alternatively, you can also use the \hypersetup command.

In the article version, you must include hyperref manually if you want to use it. You can do so by passing option hyperref to beamerarticle. It is not included automatically.

When using Unicode, you may wish to use some of the following class options:

If you use a Unicode character outside the first two code pages (which includes the Latin alphabet and the extended Latin alphabet) in a section or subsection heading, you have to use the command \PreloadUnicodePage{⟨code page⟩} to give ucs a chance to preload these code pages. You will know that a character has not been preloaded, if you get a message like “Please insert into preamble.” The code page of a character is given by the unicode number of the character divided by 256.

Note that none of these options apply to lualatex and xelatex, since both support Unicode natively without any extra packages. Most of the time using these options actually harms output quality, so be careful about what you use. If you want to have a document that allows compiling with multiple drivers, take a look at iftex, ifxetex and ifluatex packages.

Passing option utf8 to beamerarticle has the same effect as saying \usepackage[utf8]{inputenc} in the preamble.

Again, take care if you use lualatex or xelatex.

Note that you must treat lstlisting environments exactly the same way as you would treat verbatim environments. When using \defverbatim that contains a colored lstlisting, use the colored option of \defverbatim.

Example:

\usepackage{listings}

\begin{document}
\defverbatim[colored]\mycode{%
  \begin{lstlisting}[frame=single, emph={cout}, emphstyle={\color{blue}}]
    cout << "Hello world!";
  \end{lstlisting}
  }

\begin{frame}
  \mycode
\end{frame}
\end{document}

Since this package uses pstricks internally, everything that applies to pstricks also applies to msc.

When using MusiXTeX to typeset musical scores, you have to have -TeX extensions enabled. Most modern distributions enable that by default both in pdflatex and latex. However, if you have an older distribution, the document must be compiled with pdfelatex or elatex instead of pdflatex or latex.

Inside a music environment, the \pause is redefined to match MusiXTeX’s definition (a rest during one quarter of a whole). You can use the \beamerpause command to create overlays in this environment.

beamer automatically patches list-related commands using beamerpatchparalist package at the beginning of document. Besides, beamer also supports using compactitem and compactenum environments with overlays, just like the usage of enumerate environments:

\begin{compactitem}[<+->][$\bullet$]
  \item Alpha
  \item Bravo
\end{compactitem}

Commands like \includepdf only work outside frames as they produce pages “by themselves.”

If you use a professional font package, beamer’s internal redefinition of how variables are typeset may interfere with the font package’s superior way of typesetting them. In this case, you should use the class option professionalfonts to suppress any font substitution. See Section 18.2.2 for details.

You should add the option xcolor=pst to make xcolor aware of the fact that you are using pstricks.

You cannot use this package with beamer. However, you might try to use the package beamertexpower instead, see Section 24.4.

beamer automatically installs a white background behind everything, unless you install a different background template. Because of this, you must use the overlay option when using textpos, so that it will place boxes in front of everything. Alternatively, you can install an empty background template, but this may result in an incorrect display in certain situations with older versions of the Acrobat Reader.

See \usepackage[utf8,utf8x]{inputenc}.

The xcolor package is automatically loaded by beamer.cls. The same applies as to color.

When using beamer together with the pstricks package, be sure to pass the xcolor=pst option to beamer (and hence to xcolor).

The color package is not loaded automatically if beamerarticle is loaded with the noxcolor option.
