Hello I am working with the template called: Radboud University Beamer(Version1), https://www.sharelatex.com/templates/presentations, this is a beautiful template however I would like to customize it a little.

Since I changed the image of background of the first page, I am using a picture of my university, in the following part:

% Background
\pgfdeclareimage[width=\paperwidth,height=\paperheight]{bg}{myImage}
\setbeamertemplate{background}{\pgfuseimage{bg}}

Of the file called ru.sty, the text that I am using for the author of the presentation at the following part:

\author[Pim Vullers MSc]{
  Pim Vullers MSc \\\medskip
  {\small \url{[email protected]}} \\ 
  {\small \url{http://www.cs.ru.nl/~pim/}}}

    % The institute:
%  - to start the name of the university as displayed on the top of each slide
%    this can be adjusted such that you can also create a Dutch version
%  - next the institute information as displayed on the title slide
\institute[School of science]{
  Institute for Computing and Information Sciences -- Digital Security \\
  Radboud University Nijmegen}

% Add a date and possibly the name of the event to the slides
%  - again first a short version to be shown at the bottom of each slide
%  - second the full date and event name for the title slide
\date[slides Example 2010]{
  the 1st example presentation 2010 \\
  7th October 2010}

Appears not so clear, to fix this I would like to enter a box o another color to make contrast, I tried:

\begin{block}{A box to enter text}

\author[Pim Vullers MSc]{
  Pim Vullers MSc \\\medskip
  {\small \url{[email protected]}} \\ 
  {\small \url{http://www.cs.ru.nl/~pim/}}}

% The institute:
%  - to start the name of the university as displayed on the top of each slide
%    this can be adjusted such that you can also create a Dutch version
%  - next the institute information as displayed on the title slide
\institute[School of Science]{
  Institute for Computing and Information Sciences -- Digital Security \\
  Radboud University Nijmegen}

% Add a date and possibly the name of the event to the slides
%  - again first a short version to be shown at the bottom of each slide
%  - second the full date and event name for the title slide
\date[slides Example 2010]{
  the 1st example presentation 2010 \\
  7th October 2010}


\end{block}

But I failed since the box is shown before the title of the presentation and is not displaying the information.

I am not sure why is failing since I made a prove and I create another frame of the presentation, just to test this function and it worked well, however I believe that due to the fact that I want to alter the first page of the presentation maybe I need to use a distinct approach, I would like to receive any advice to overcome this situation, thanks any how.

Reset to default

Your approach won't work, as \author etc. are just macros to store the information, not to use them. So at the place you tried to insert the block, the document not even started.

However there are other possibilities. All the information are by default inside boxes. These boxes are transparent in your example, but you can set the colour 

\setbeamercolor{author}{parent=title}
\setbeamercolor{institute}{parent=title}
\setbeamercolor{date}{parent=title}

enter image description here

Or if you don't like this, you can define your own title page

\makeatletter
\setbeamertemplate{title page}{%
  \vbox{}
  \vfill
  \begingroup
    \centering
    \begin{beamercolorbox}[sep=8pt,center,colsep=-4bp,rounded=true]{title}
      \usebeamerfont{title}\inserttitle\par%
      \ifx\insertsubtitle\@empty%
      \else%
        \vskip0.25em%
        {\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle\par}%
      \fi%     
    \end{beamercolorbox}%
    \vskip1em\par
    \begin{beamercolorbox}[sep=8pt,center,colsep=-4bp,rounded=true]{author}
      \usebeamerfont{author}\insertauthor
    \end{beamercolorbox}
    \begin{beamercolorbox}[sep=8pt,center,colsep=-4bp,rounded=true]{institute}
      \usebeamerfont{institute}\insertinstitute
    \end{beamercolorbox}
    \begin{beamercolorbox}[sep=8pt,center,colsep=-4bp,rounded=true]{date}
      \usebeamerfont{date}\insertdate
    \end{beamercolorbox}\vskip0.5em
    {\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic\par}
  \endgroup
  \vfill
}
\makeatother

and insert whatever code you want there.

  • just another comment I realized that with a solid red the image of background is not visible, I tried changing the color of the box with \setbeamercolor{author}{fg=red!80!black,bg=red!20!white}, however this way gave me solid colors do you know how to get a red a little bit transparent?

  • I really appreciate the support I tried with that but again only work with blocks, it is not working with parts such as \author that as you explained me before are just macros to store the information...
