Placement of logo in the default beamer theme

Question

I follow Logo on the top right of each slide in Warsaw theme but the beamer default theme is different.

I would like to add a logo to each beamer slide in

• top right corner
• bottom right corner

I know I should redefine beamertemplate{frametitle) found in http://tug.ctan.org/macros/latex/contrib/beamer/base/beamerouterthemedefault.sty

Where to start?

Answer 1

top right image

You can tweak the vertical position by modifying the \raisebox, the horizontal position via the width of the minipage.

bottom right corner

use \logo{...}

\documentclass{beamer}

\logo{\includegraphics[width=1cm]{example-image}}

\makeatletter
\setbeamertemplate{frametitle}{%
  \ifbeamercolorempty[bg]{frametitle}{}{\nointerlineskip}%
  \@tempdima=\textwidth%
  \advance\@tempdima by\beamer@leftmargin%
  \advance\@tempdima by\beamer@rightmargin%
  \begin{beamercolorbox}[sep=0.3cm,left,wd=\the\@tempdima]{frametitle}
    \begin{minipage}{.87\@tempdima}%
        \usebeamerfont{frametitle}%
        \vbox{}\vskip-1ex%
        \if@tempswa\else\csname beamer@fteleft\endcsname\fi%
        \strut\insertframetitle\strut\par%
        {%
          \ifx\insertframesubtitle\@empty%
          \else%
          {\usebeamerfont{framesubtitle}\usebeamercolor[fg]{framesubtitle}\insertframesubtitle\strut\par}%
          \fi
        }%
        \vskip-1ex%
        \if@tempswa\else\vskip-.3cm\fi% set inside beamercolorbox... evil here...
      \end{minipage}%
      \raisebox{-0.3cm}{\includegraphics[width=1cm]{example-image}}
  \end{beamercolorbox}%
}
\makeatother

\begin{document}

\begin{frame}
\frametitle{title}
    abc
\end{frame}
