\begin{slide}
\heading{About Electronic Presentations}
\begin{itemize}
\item Many disadvantages, but a few reasons to go with the tide
  \begin{itemize}
  \item Classic: Saves paper, plastic.  Easier to retrieve and store.
  \item Often Attractive.
  \item Occasionally beneficial: Easier to navigate. Easier to teach
    (for example, spatial data structures). Easier to learn. 
  \end{itemize}
\item Things to keep in mind
  \begin{itemize}
  \item Page layout: Matching screen dimensions, aspect ratio
  \item Adding emphasis: Color, animation
  \item Adding links: Enabling the user to navigate
  \end{itemize}
\end{itemize}
\end{slide}


\begin{slide}
\heading{About Microsoft PowerPoint}
\begin{itemize}
\item Front runner (for non technical presentations)
\item Several advantages: Robust, Large number of templates, Excellent
  integrated graphic tool, animation support, link support, WYSIWIG,
  audience notes
\item A few disadvantages: Not light weight, poor math support,
  imprecise placement, limited export options
\item Key Point: Your technical report is not written in PowerPoint!
\item Magic Point has different limitations
\end{itemize}
\end{slide}


\begin{slide}
\heading{Turning to  \LaTeX\  And Friends}
\begin{itemize}
\item Why?  Why Not? (Compare previous slide on disadvantages)
  \begin{itemize}
  \item What's possible: Use of color, links
  \item (In addition) What's the promise: Beautiful math, More control
  \item What's the drawback: Embedded and other animation, Runtime Overlay
  \end{itemize}
\item How?
  \begin{itemize}
  \item Use an appropriate document class: slides, foils, seminar
  \item Use appropriate packages: color, hyperref
  \item Use other tools: Acroread, Browsers (IE), mpegplay, realaudio
  \end{itemize}
\item Examples to follow 
\end{itemize}

\begin{slide}
\heading{Comparisons of Strategies}
\begin{itemize}
\item Can't stay with \verb+dvi+.
  \begin{itemize}
  \item Color, link, fonts cause  problems. 
  \item Special versions of drivers can handle these.
  \item \verb+xdvi+, \verb+dviwindo+, \verb+dviout+ are not really
  presentation tools 
  \end{itemize}
\item Downgrade to HTML using \verb+latex2html+, \verb+tth+, \verb+TeX4ht+
  \begin{itemize}
  \item Beautiful browsers are available. Lightweight solutions if
  pure text or straightforward \LaTeX. Also consider MathML. 
  \item Weak math support (math is translated to images)
  \item Plugin solution is possible (IBM TechExplorer)
  \item Precise placement is a problem.
  \end{itemize}
\item Work with PDF
  \begin{itemize}
  \item Factor of two size increase as compared to dvi
  \item Acroread is universal, and acceptable as a presentation tool
  \end{itemize}
\end{itemize}
\end{slide}

\begin{slide}
\heading{Wrinkles in the \LaTeX\ World}
\begin{itemize}
\item The good news: standard \LaTeX\ document classes handle the
  basic issues of 
  presentation (large size font, overlays, self contained pages,
  vertically centered pages)
  \begin{itemize}
  \item The \verb+slides+ document class: Standard but lacks bells and
    whistles 
  \item The \verb+foiltex+ has restricted licenses (copyright owned by
    IBM)
  \item The \verb+seminar+ document class is free, and has a long
    history. Standard in Redhat teTeX distribution.
  \end{itemize}
\item The bad news: Which \TeX\ to use? 
  \begin{itemize}
  \item Problem: color is non standard.  Need to convert to pdf using
    dvipdf. (ps2pdf is not an option) 
  \item Accept this reality and work with pdflatex but  debugging with
    pdflatex and acroread is very slow 
  \end{itemize}
\item Possible solution: Work with both teTeX  and pdflatex!
\end{itemize}
\end{slide}

\begin{slide}
\heading{A Few Words on the {\tt seminar} class}
\begin{itemize}
\item Mix both portrait and landscape in presentation (impossible in
  PowerPoint?!) 
\item  Recommended for presentations: \verb+\documentclass{seminar}+
and \verb+\usepackage{graphicx,times,semrot,sem-a4}+
\item For foils, use the \verb+portrait+ option.
\item Make frames using the \verb+fancybox+ package (Can put
  background text too).
\item Color handled with \\ \verb+\usepackage[dvips]{pstcol}\usepackage{semcolor}+
\item Can have default logo at the bottom
\item And a list of slides!
\end{itemize}

\begin{slide}
\heading{About PDF}
\begin{itemize}
\item  Compressed descendant of the PostScript language
  \begin{itemize}
  \item Not a programming language (has JavaScript support though)
  \item Page independent from resources
  \item Hypertext and security supported
  \item Font need not be part of the document
  \end{itemize}
\item Adobe makes money in the create PDF process (specs are open)
\item Can be used to create \emph{forms} (like HTML forms) with
  textfield, checkboxes, and so on.
\end{itemize}

\end{slide}

\begin{slide}
\heading{About {\tt hyperref}}
\begin{itemize}
\item A \LaTeX\ front to generate marks understood by Acrobat
\item Extends cross-refercing commands
\item Supported by xdvi, dvips, pdftex, dvipdfm
\item Two common packages (colorlinks, backref)
\item Can be used to control the acrobat menu (bookmarks, toolbar, and
  so on).
\end{itemize}
\end{slide}


\begin{slide}
\heading{About pdfscreen}
\begin{itemize}
\item Wrapper around hyperref to make attractive screen presentations 
\item Panels to let you navigate
\item Automatic color screen

\end{itemize}
\end{slide}


\begin{slide}
\heading{Options to Explore}
\begin{itemize}
\item ppower4: Postprocessor to enable  incremental additions to pages
\item texpower: Similar, doespage transitions, color highlighting and
  incremental page display
\item propser: A powerpoint lookalike built on top of seminar
\item ifmslide: Built on top of texpower
\end{itemize}
