\section{Introduction}
\begin{frame}{Slide-Making in \LaTeX}
We assume that you can use \LaTeX. If not, you can refer to \href{https://www.overleaf.com/learn/latex/Learn_LaTeX_in_30_minutes}{this page}.
\href{https://www.overleaf.com/learn/latex/Beamer}{Beamer} is one of the most popular and influential document classes for slide-making in \LaTeX. You can find its \href{https://mirror-hk.koddos.net/CTAN/macros/latex/contrib/beamer/doc/beameruserguide.pdf}{full manual here}.
Here, we will only introduce the basic functionalities so you can master them immediately.
\end{frame}
\begin{frame}{Beamer vs. MS PowerPoint}
Compared to Microsoft PowerPoint, \LaTeX\ and Beamer provides these advantages:
\begin{itemize}
\item Beamer produces a \texttt{.pdf} file with no problems on fonts, formulas, or program versions.
\item Math typesetting in \LaTeX\ is much easier, e.g.,
\begin{equation*}
\mathrm{i}\,\hslash\frac{\partial}{\partial t} \Psi(\mathbf{r},t) =
-\frac{\hslash^2}{2\,m}\nabla^2\Psi(\mathbf{r},t)
+ V(\mathbf{r})\Psi(\mathbf{r},t).
\end{equation*}
\end{itemize}
\end{frame}
\section{Examples}
\begin{frame}[fragile]{Document Class}
To begin with, just use \texttt{beamer} document class with \texttt{poly} theme. It should be noted that the \texttt{poly.sty} file should be included in the same directory as the \texttt{main.tex} file.
\begin{block}{Preamble about the document class}
\begin{lstlisting}[language=TeX]
\documentclass[10pt,aspectratio=169]{beamer}
\usepackage{poly}
\end{lstlisting}
\end{block}
You can change the \texttt{aspectratio} to \texttt{43} to adjust the slide aspect ratio to 4:3.
\end{frame}
\begin{frame}[fragile]{Metadata}
You can change the metadata displayed on the title slide:
\begin{block}{Metadata}
\begin{lstlisting}[language=TeX]
\title{Your Title}
\subtitle{Your Subtitle}
\author{First Author, Second Author}
\institute[COMP]{Department of Computing}
\date{Date}
\end{lstlisting}
\end{block}
Once settled, you can render the title slide with the command \verb|\maketitle| in the body.
\end{frame}
\begin{frame}[fragile]{Texts}{In a Sequence}
\begin{itemize}[<+->]
\item A typical slide has bulleted points.
\item These can be uncovered in sequence.
\item When rendered, they will be separated into multiple slides.
\end{itemize}
\end{frame}
\begin{frame}{Images}
Adding images works like in normal \LaTeX:
\begin{figure}[hbt]
\includegraphics[width=0.5\textwidth]{source/tagline}
\caption{A sample of image}
\end{figure}
\end{frame}
\begin{frame}{Columns}
Splitting the page is easy and common.
Typically, one side has a picture and the other text:
\vspace{20pt}
\begin{columns}
\begin{column}{0.6\textwidth}
This is the first column.\\[10pt]
You can have some texts here.
\end{column}
\begin{column}{0.3\textwidth}
And this is the second one.\\[10pt]
You can have some pictures or tables here.
\end{column}
\end{columns}
\end{frame}
\begin{frame}{Fonts}
The priority when choosing a font is readability.
Here, we give some advice:
\begin{itemize}
\item Use serif (default) fonts only with high-resolution projectors or monitors.
\item Use \textsf{sans-serif} fonts otherwise.
\item Use \textit{italic} or \textbf{bold} fonts to emphasize or highlight points.
\item We also provide an \alert{alert} font for emphasise.
\item Use \texttt{monospace} fonts to display codes.
\end{itemize}
\end{frame}
\section{Summary}
\begin{frame}{Good Luck!}
\begin{itemize}
\item Enough for an introduction! You should know enough by now.
\item If you have corrections or suggestions, please feel free to contact \href{mailto:ruisong20@gmail.com}{me}!
\item You can also find this project on \href{https://github.com/wurahara/PolyU-Beamer-Slides}{Github}! Stars are welcome!
\end{itemize}
\end{frame}
\backmatter % generate the final slide
