Changing fontsize within osx-presentation

Question

This question is based on the second answer from Is there a nice solution to get a "presenter mode" for Latex presentations? where the author of the answer wrote a tool called osx-presentation.

I am wondering if anywhere is aware of a way to change the font size and font color for the notes?

The LaTeX command to include a note is

\marginnote{\pdfcomment[icon=note]{Your notes goes here.}}

I tried specifying the size like

\marginnote{\pdfcomment[icon=note]{\tiny Your notes goes here.}}

and

\marginnote{\pdfcomment[icon=note]{\Large Your notes goes here.}}

But the size does not appear to be changing. I'm not sure if I'm doing it wrong or if there's something specific to osx-presentation that requires a different method to change the size?

Answer 1

I'm not sure I understand you quite right, but it seems you want to change the fontsize of the printed \pdfcomment.

You tried to use \pdfcomment[icon=note]{\tiny Your notes goes here.}. That does not work, because the used fontsize for displayed pdf comment is set with the class option fontsize=15bp of package pdfcomment.

As far as I can see you can not change the fontsize with \tiny or \Large, the documentation of pdfcomment does not mention any possibility to do this.

You can also test the line

\marginnote{\pdfcomment[icon=note]{\tiny Your notes goes here. \Large Your notes goes here.}

to see that are no font size changings in your pdf comment (and no warnings or error messages too)!

You can only define the general fontsize for all pdf comments with class option fontsize:

\usepackage[fontsize=15bp]{pdfcomment}

You can use the following code for testing:

\documentclass{beamer}

\mode<presentation>{%
  \usetheme{Berlin}
}

\usepackage{graphicx} % Allows including images
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{cancel}
\usepackage{algorithm2e}
\usepackage{float}
\usepackage{caption}
\usepackage{fancyvrb}
\usepackage[toc,page]{appendix}

\usepackage{subfig}
\usepackage{color}
\usepackage[export]{adjustbox}
\usepackage{multicol}
\usepackage{footnotebackref}
\usepackage[absolute,overlay]{textpos}
% define some useful commands
\usepackage{lmodern}
\usepackage{etoolbox}
\usepackage{xfrac}

\usepackage{hyperref}
\usepackage[fontsize=15bp]{pdfcomment}
%\usepackage[draft]{pdfcomment}

\setbeamerfont{footnote}{size=\tiny}

\AtBeginSection[]{
  \begin{frame}
  \vfill
  \centering
  \begin{beamercolorbox}[sep=8pt,center,shadow=true,rounded=true]{title}
    \usebeamerfont{title}\insertsectionhead\par%
  \end{beamercolorbox}
  \vfill
  \end{frame}
}


\begin{document}
\begin{frame}
\titlepage % Print the title page as the first slide

my slide content here

\marginnote{\pdfcomment[icon=note]{\tiny Your notes goes here. \Large Your notes goes here.}}
\end{frame}

\end{document}

If you change the line with the \pdfcomment to the following

\marginnote{\pdfcomment[icon=note]{Your notes goes here. Your notes goes here.}}

you will see no differences. So changing the fontsize does not work here ...

Please see that I deleted all the packages you called twice or more and I changed the order of calling the packages ...

Because I can not create an screenshot of the resulting pdf comments I ommited the image for the result :-(
