beamerfootnotespositioning
I'm using beamer for a presentation, and introducing some references along it using \footonote. However, the spacing between the bottom of the slide and the last footnote reference is too big : I would like to save as much space as possible, for exemple by aligning the slide number and the footnote line.
How can I modify this in a clean way ? I would like to have the same result as using the footmisc package, which can not be used in beamer.
Thanks
No automated solution, but perhaps \enlargethispage can help. It should quite easy to measure the gap between text and footnotes on the last chapter page and issue an \enlargethispage{-??\baselineskip}, where ?? stands for the number of lines to cut from the page.
Let's hope that the among the requirements there's a page number at the bottom.
Of course this should be done when the text is completely definitive.
Depending on how many footnote you have, you can use textpos to emulate a footnote like this:
\documentclass{beamer}
\usepackage[absolute,overlay]{textpos} % new package
\usetheme{Warsaw}
\newenvironment{reference}[2]{ %
\begin{textblock*}{\textwidth}(#1,#2) % This is the code
\footnotesize\it\bgroup\color{white}}{\egroup % for the emulated
\end{textblock*}} % footnote environment
\begin{document}
\begin{frame}
\begin{reference}{10mm}{93mm} % this is the code used inside a
$^1$foo % frame to state the position
\end{reference} % of the footnote
abc$^1$
\end{frame}
\end{document}
which produces this:
knowing that a beamer slide is 128*96mm in size you can place text pretty much anywhere with this method.

This causes probably more problems then it solves (for example overlapping if the footnotes are longer then one line), but in case you can sacrifice the navigation symbols:
