Using the Acrobat Reader for presentations

• Easy solution:

1. Use FoilTEX (or any other slide package).

FoilTEX uses a larger font, allows for landscape mode, slide

titles, etc, and is very easy to use.

2. Use pdflatex to produce a pdf-file.

pdflatex works just like LATEX, but produces a pdf-file.

3. View the pdf-file in Acrobat Reader, fullscreen mode.

A small FoilTEX example

\documentclass[30pt,landscape]{foils}\usepackage[pdftex]{geometry}\geometry{headsep=3ex,hscale=0.9}\begin{document}\foilhead{Top 3 reasons to emigrate}\begin{enumerate}\item Rosengren\item Sahlin\item Winberg\end{enumerate}\end{document}

Including pictures

PDF files can be included “as is”.

\usepackage[pdftex]{graphicx}

\includegraphics{mdh.pdf}

Postscript files must be converted, using e.g. epstopdf.

I’ll describe METAPOST later.

What about bitmaps?

JPEG and PNG images can also be included. . .

but remember that bitmap images don’t scale well.

Color

• The color package is the preferred way to use colors.

• New colors are defined in RGB or CMY, for instance:

\definecolor{chocolate}{rgb}{0.82,0.41,0.12}

• Text can be set in a certain color,

\textcolor{chocolate}{$\phi = {(1+\sqrt{5}) \over 2}$}

which comes out as φ = (1+√

Pros and cons

• Good: Platform independent.

• Good: Inherits all of LATEX’ power:

– Typesetting of mathematical formulæs:

limn→∞

n∑i=1

1i2

=π2

6

– Automatic referencing, command definitions, etc.

• But: Not as exciting as e.g. Powerpoint.

Using links

You can define a label on a page with

\toptarget{toc}

and then later reference on another page with

\toplink{toc}{Table of Contents}

which will be shown as Table of Contents.

As usual with references, you have to run LATEX twice.

Multimedia and external applications

Movies and other scripts can be invoked using

\href{run:}{filename}{title}

Calling applications is however more platform dependent.

Backgrounds and page transitions

• Backgrounds can have a solid color or a gradient.

pagecolor{color} solid color

vpagecolor[color 1]{color 2} vertical gradient

hpagecolor[color 1]{color 2} horizontal gradient

• On this page I have chosen the romantic sunset motif.

\definecolor{bgblue}{rgb}{0.4,0.6,1.0}\definecolor{bgred}{rgb}{1.0,0.6,0.4}\vpagecolor[bgred]{bgblue}
