[Tex/LaTex] Positioning logo in the front page as well as slides

beamer

Question 1:
I am creating a slide template for a presentation in LaTex using Beamer package. I found the placement of logo in the slide is not that easy. Instead of placing the logo in the same position throughout the slides, I want to place the logo in the middle or a bit up from the middle in the title slide. Is it possible?

Question 2:
In the slides after the titleslide I want to have the logo in the top right corner. So, I put this command,

\logo{\includegraphics[height=0.8cm]{logo.eps}\vspace{220pt}}

It went well:

Logo visible

However, if I change the color of the top bar then the logo goes behind the bar and it's no longer visible:

Logo not visible anymore

Is there any way by which I can put the logo on the top?

Best Answer

Question 1: You can use any of the fields given by \author, \title, \date, or \institute to place the image in the title page; if none of those fields allow you to achieve the desired placement, you can use the textpos package. The example below uses the \author field to add the image.

Question 2: With the help of the textpos package you can add the logo to the frametitle template using \addtobeamertemplate.

A simple example code:

\documentclass{beamer}
\usetheme{Madrid}
\usecolortheme{beaver}
\usepackage{textpos}

\title{The title}
\author[The author]{\includegraphics[height=1cm,width=2cm]{cat}\\The Author}
\institute[Inst.]{The Institute}
\date{\today}

\begin{document}

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

\addtobeamertemplate{frametitle}{}{%
\begin{textblock*}{100mm}(.85\textwidth,-1cm)
\includegraphics[height=1cm,width=2cm]{cat}
\end{textblock*}}

\begin{frame}{Motivation}
Now the logo is visible
\end{frame}

\end{document}

As osjerick mentions in a comment, the above solution won't behave correctly if \framesubtitle is used (the image will shift downwards); in this case, a TikZ approach can be used to prevent the movement:

\documentclass{beamer}
\usetheme{Madrid}
\usecolortheme{beaver}
\usepackage{tikz}

\title{The title}
\author[The author]{\includegraphics[height=1cm,width=2cm]{cat}\\The Author}
\institute[Inst.]{The Institute}
\date{\today}

\begin{document}

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

\addtobeamertemplate{frametitle}{}{%
\begin{tikzpicture}[remember picture,overlay]
\node[anchor=north east,yshift=2pt] at (current page.north east) {\includegraphics[height=0.8cm]{cat}};
\end{tikzpicture}}

\begin{frame}{Motivation}
Now the logo is visible
\end{frame}

\begin{frame}{Motivation}
\framesubtitle{A}
Now the logo is visible
\end{frame}

\end{document}
