%% SECTION 3 - OPTIONS
%%
\section{Quick options \& customisation}
\begin{frame}[fragile]{(A) Math font}
In preamble of demo.tex there are a few options to easily modify or customise your presentation
\medskip
Default sans-serif math:
\begin{itemize}
\item $ c^2 = a^2+b^2 - 2ab \cos\gamma $
\item $e^{ \pm i\theta } = \cos \theta \pm i\sin \theta$
\end{itemize}
\medskip
To change to serif math everywhere
\begin{itemize}
\item $ \mathnormal{c^\mathrm{2} = a^\mathrm{2}+b^\mathrm{2} - \mathrm{2}ab \cos\gamma} $
\item $\mathnormal{e^{ \pm i\theta } = \cos \theta \pm i\sin \theta}$
\end{itemize}
\medskip
\verb+ \usefonttheme[onlymath]{serif}+
\end{frame}
\begin{frame}[fragile]{(B) Change primary colour}
\begin{itemize}
\item Default color for frame titles, itemization and other elements is \textcolor{pblue}{blue}
\item You can redefine primary color, to e.g. orange, by changing RGB values:
\end{itemize}
\medskip
\verb+\definecolor{pblue}{RGB}{+{\color{red}\verb+206,125,66+}\verb+}+
\end{frame}
\begin{frame}[fragile]{(C) First page foreground image}
\begin{itemize}
\item Add additional small foreground image on the title page
\item Add in preamble:
\end{itemize}
\vspace{12pt}
\begin{verbatim}
\titlegraphic{\includegraphics[height=3cm]{myimage.png}}
\end{verbatim}
\medskip
\centering Not that this not for the background image. Go to: \hyperlink{background_image}{\beamergotobutton{First page background}}
\end{frame}
\begin{frame}[fragile]{(D) Footline logo}
\begin{itemize}
\item Add your logo in bottom right corner
\item Command \verb+\logo+ can be removed, and no logo will be shown
\end{itemize}
\vspace{12pt}
\begin{verbatim}
\logo{\includegraphics[height=0.7cm]{logo.png}\hspace{12pt}
\vspace{-6pt}}
\end{verbatim}
\end{frame}
\begin{frame}[fragile]{(E) Footline information bar}
\begin{itemize}
\item Add information on bottom of every frame
\item Four options:
\begin{itemize}
\item \verb+infoline+ ~:~ Text line with author, titile and institute
\item \verb+navigation+ ~:~ Dots by frame and section showing progress
\item \verb+navsym+ ~:~ Navigation symbols
\item Nothing (delete/disable all)
\end{itemize}
\smallskip
\item Options cannot be combined
\item Can be combined with logo
\end{itemize}
\medskip
\verb+\setbeamertemplate{footline}[+{\color{red}\verb+infoline+}\verb+]+
\end{frame}
\begin{frame}[fragile]{(F) Widescreen}
Default screen ration is 4:3. Load the following package in the preamble to make all frames wider to 16:9 ratio:
\begin{verbatim}
\usepackage[orientation=landscape,size=custom,
width=16,height=9,scale=0.45,debug]{beamerposter}
\end{verbatim}
Title page or other frames should not get (too) distorted because of it.
\end{frame}
%%
%% SECTION 4 - GALLERY
%%
\section{Title page background templates gallery}
\begin{frame}[fragile]{First page background}\label{background_image}
\begin{itemize}
\item Easily change first page background image with a selection of templates, or any photo you want (change filename \textcolor{red}{in red})
\item All included images are based on photos that free for commercial and non-commercial use. Attribution is not required.
\item Background image can be removed (delete the entire line)
