# How could I modify vertical space between inst on titlepage?

I think everything is in the question. My problem is that my graphic is half visible because of the 4 \inst I have on the title page... So my approach to get my graphic 100% visible is to decrease the space between the \insts.

Here is a MWE :

\documentclass[slidetop,11pt, xcolor=dvipsnames]{beamer}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[frenchb]{babel}

\usetheme{Warsaw}

\title[ bla bla bla bla bla bla bla]{Bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla}
\author[ bla bla bla bla]{ bla bla bla\inst{1}\and  bla bla bla \inst{2}\and  bla bla bla         \inst{1}\and  bla bla bla \inst{1} \and  bla bla bla \inst{3} \and bla bla bla \inst{4} \and  bla bla bla \inst{4}}
\institute[XLIM]{\inst{1}  bla bla bla bla bla bla bla bla bla bla bla bla bla bla \and %
\inst{2}  bla bla bla bla bla bla \and
\inst{3}  bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla     \and
\inst{4}  bla bla bla bla bla bla bla bla bla bla}
\date{bla bla bla bla bla}
\titlegraphic{\includegraphics[height=1cm]{./figures/logo_drapeau.jpeg}}

\begin{document}
\frame{\titlepage}

\end{document}


Which produces :

The default is to insert a space of 1em between \inst items (inserted using \and) - see beamerbasetitle.sty. This insertion is done by a macro \beamer@andinst which has the following definition:

\def\beamer@andinst{\\[1em]}


\makeatletter
\def\beamer@andinst{\\[0.5em]}
\makeatother


would half the distance inserted usually. To insert no space at all, use 0pt. Here is a minimal example where \date is used to indicate the vertical space inserted by \and:

\documentclass{beamer}

\usetheme{Warsaw}

\title[ bla bla bla bla bla bla bla]
{Bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla}
\author[ bla bla bla bla]{%
bla bla bla \inst{1} \and
bla bla bla \inst{2} \and
bla bla bla \inst{1} \and
bla bla bla \inst{1} \and
bla bla bla \inst{3} \and
bla bla bla \inst{4} \and
bla bla bla \inst{4}}
\institute[XLIM]{\inst{1} bla bla bla bla bla bla bla bla bla bla bla bla bla bla \and
\inst{2} bla bla bla bla bla bla \and
\inst{3} bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla \and
\inst{4} bla bla bla bla bla bla bla bla bla bla}
\titlegraphic{\includegraphics[height=1cm]{example-image}}

\begin{document}

\date{1em}
\frame{\titlepage}

\makeatletter
\def\beamer@andinst{\\[0.5em]}
\date{0.5em}
\makeatother

\frame{\titlepage}

\makeatletter
\def\beamer@andinst{\\[0pt]}
\date{0pt}
\makeatother

\frame{\titlepage}

\end{document}

• Thank you Werner. Exactly what I looked for ! So what is your secret ? – rhum187 Sep 18 '14 at 7:42
• @rhum187: Secrets? What? – Werner Sep 18 '14 at 14:06
• It was exactly the right code lines that I need to so I assume you read my thoughts. Anyway I was kidding because I put a lot of efforts to not ask to the forum and figure it out my myself but I gave up and finally ask... – rhum187 Sep 18 '14 at 14:12
