Problem using Biolinum font with Beamer in pdflatex liantze 10/13/11 8:11 AM
I'm using the Biolinum font (part of the libertine package) in a Beamer
presentation. This used to work fine, until a recent slew of updates.
Notice how, in the following, the heights of the headline and footline
boxes are very small, almost as if they can't detect a font size. The
same happens with the enumerated list markers.

-----------8<------------
\documentclass{beamer}
\usetheme{Warsaw}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine}

\author{An Author}
\title{A Presentation}

\begin{document}
\begin{frame}
\maketitle
\end{frame}

\section{Intro}
\begin{frame}
\begin{enumerate}
\item Hey
\end{enumerate}
\end{frame}
\end{document}
-----------8<------------

The problem is only with the Biolinum font, i.e. the sans serif font
supplied by the libertine package. If you add

\usefonttheme{serif}

or even use a different sans serif font altogether, such as

\usepackage{helvet}

then the headline and footline boxes, as well as the enumerate list
marker, will have the correct heights. This happens with both TeXLive
and MikTeX.

While I know xelatex is one possible solution, does anyone know how to
solve this problem if one absolutely has to use pdflatex?


Many thanks in advance,

That's obviously a bug in the font. It doesn't set the "ex" value
correctly. You should make a bug report.

You can reset the value, but I don't know how you can add this to
the beamer font command.

\documentclass{article}


\usepackage[T1]{fontenc}
\usepackage{libertine}
\begin{document}
\sffamily x \rule{1ex}{1ex}

\rmfamily x \rule{1ex}{1ex}

\sffamily x \fontdimen5\font=\fontcharht\font`\x \rule{1ex}{1ex}
\end{document}

Thank you Ulrike. I've just discovered that a bug about this has indeed
been filed (and is still open). Funny how I didn't see it in the bug
list earlier this evening... *shamefaced*


Thanks again and best regards,

Thank you, Robin, modifying the .fd files did the trick!

Can I also say a personal "thanks" for your hard and excellent work at
maintaining the FAQs? It remains my first reference whenever I'm
wondering how to do something.

I've received a complaint about a Biolinum type1 font which is apparently similar to this. Please enlighten me where the ex value is set in a pfb font. The otf version doesn't have the same issue when xelatex is used. The pfb is generated by cfftot1 from the otf font without any modification (except the FontName).

Well if you mean there is a problem when the font is used with
pdflatex: the value must be in the tfm-file. And the tfm-file
normally gets it from the afm and the "XHeight" value. But there are
no afm files in the package so I can't check what their value is and
I don't have today the time to run autoinst.

But I can confirm that the ex-value is wrong in the type1 case: it
is about 1.38pt instead of 4.3pt:

\documentclass{book}
\usepackage[biolinum]{libertine}

\begin{document}
\showthe\fontdimen5\font %ok

\sffamily abc \showthe\fontdimen5\font %wrong

\fontdimen5\font=\fontcharht\font`\x \rule{1ex}{1ex}
\showthe\fontdimen5\font %now ok.
\end{document}

Thanks. The afms aren't generated by otftotfm and I never see them using
autoinst. But I think I've managed to fix the problem.

From the discussion at linuxlibertine.org, I learned that the original
(2011) bugs were introduced by a buggy version of fontforge and that
the current otfs didn't have those bugs; indeed the Beamer problems
don't arise with xelatex or lualatex. But I had unknowingly used
fontforge-2011 to change the FontNames and re-introduced the original
bugs!

I've now installed fontforge-2012, re-generated and over-written the
pfbs and support files for Biolinum, and the Beamer problems seem to be
gone. The ex value is 4.6pt, which is perhaps more than it should be but
better than 1.38pt.
