\hangindent=3.5cm \hangafter -5 \noindent This is test file for
\texttt{ocgtools} package. You can (using \texttt{pdflatex}) insert
hidden \TeX{} material into PDF files and open/close by clicking
active links. The active links in this document are pictures (like the
picture in this paragraph) or blue text. There are two kinds of
behavior
\begin{itemize}
\item OCG spans over allmost whole PDF pages (with black or
transparent boundary) and can be hidden by clicikng anywhere in the
page -- \makeatletter
\ocgtext[0pt,bg=red,fg=yellow]{Try it here!}{Click
\ifocg@hide@button anywhere \else red cross \fi to close.} \makeatother
\item OCG is small and can be hidden either with the same link which
opens this text or with red mark on the right top corner --
\ocgminitext[4cm, bg=red]{Try it here!}{Click the same link or the red mark
to close.}
\end{itemize}
\beamernewpage Note that the pictures may look darker in Adobe Reader
on Linux if you use package option \texttt{transparent} (means
transparent boundary of the OCG's, used for example in demos for
Beamer class and \verb|pdfscreen.sty| package). For comparison you can
look at the original picture
\href{http://math.mendelu.cz/en/analyza?lang=en}{here}) or at the
demos which use \verb|web.sty| package. \ocgtext[5cm,fg=red]{PDF viewer}{More
preciselly, Adobe Reader. \par \bigskip It is well known program.
You can install it on both Linux and Windows.} uses another
rendering when trasparency is called and this seems to be system
dependent. So be carefull when combining

This is some \ocgtext{random text}{anmf asdfh akdfjha adfjh akjdfh }
to see that \ocgminitextlb{\texttt{wrapfig}}{Wrapfig is a package for
\LaTeX.} works and wide pictures are scaled properly. Several
options are available for the package \verb|ocgtools|:
\ocgminitext[6cm]{transparent}{\texttt{beamer} and \texttt{pdfscreen}
demo files are compiled with \texttt{transparent} option -- the
black boundary of big layers is opaque.},
\ocgminitext[6cm]{insertvisible}{The file \texttt{ocgtools-example-web.tex}
is compiled with \texttt{insertvisible} option. The layers are
inserted as visible layers and are turned to invisible when the PDF
file is opened.},
\ocgminitext[8cm]{nobutton}{Normally the pages
with active layers have a transparent button which can be used to
hide this layer. The user simply clicks anywhere and the layers
become hidden. In some viewers (like Foxit Reader) the button is not
100\% transparent. This option allows not to include the big button
to hide layers. The layers can be closed by clicking the red cross
below. Demo files based on \texttt{pdfscreen} are compiled with this option.
Use this option to make the document accessible to Foxit Reader users.},
\ocgminitext{noocg}{All OCG's are ignored},
\ocgminitext{inactive}{The same as
\texttt{noocg}}, \ocgminitext{active}{OCG's are inserted, overrides
\texttt{inactive} and \texttt{noocg}},
\ocgminitext[6cm]{noprogressmsg}{No messagae about processing OCG's at
the first page when document is opened.},
\ocgminitext[8cm]{minimouseover}{\texttt{web} and \texttt{beamer} demo
files are compiled with \texttt{minimouseover} option. You can open
the minilayer by mouseover action in the area which is in the form
of invisible square 8pt$\times$8pt placed at the bottom right corner
of the referrence text.},
\ocgminitext[8cm]{mouseover}{The same as
\texttt{minimouseover}, but works also for big layers. No demo file is
compiled with this option.},
\ocgminitext[8cm]{nopageclose}{By default, layers and buttons for hiding them are
turned into hidden when entering a page. This option turns this behavior off.
Demo files based on \texttt{pdfscreen} are compiled with this option.}
(each option has an associated
minilayer with an explanation). Examples distributed with the package
are in the form of demo files based on three packages (\verb|beamer|,
\verb|web|, \verb|pdfscreen|). Each example has three variants with no
panel, with panel on the right and on the left and each example is
compiled with different options. The current document is compiled with
the following options: {\bfseries \makeatletter
\if@ocgtools@transparent transparent, \fi \if@ocgtools@insertvisible
insertvisible, \fi \ifocg@hide@button \relax \else nobutton, \fi
\ifx \ocgtools@progressmsg\relax
noprogressmsg, \fi \if@ocgtools@mouseover mouseover,\fi
\if@ocgtools@minimouseover minimouseover,\fi \if@ocgtools@pageclose\else nopageclose,\fi \makeatother }

\verb|\def\defaultocgfontcolor{green}| on this page.

\section{Few more tests}
Package \verb|ocgtools.sty| redefines output routine via
\verb|atbegshi.sty| package. From this reason it may be incompatible
with some other packages dealing with output routine. However, the
package \verb|eso-pic.sty| works fine.
Test for placing OCG's:
\hbox to \hsize{\hss\begin{minipage}{0.2\linewidth}
\ocgminitextlb{lb}{This is optional OCG.}
\ocgminitextrb{rb}{This is optional OCG.}

\ocgminitextrt{rt}{This is optional OCG.}

\ocgminitextrt{rt}{This is optional OCG.}
\end{minipage}
\hss
}
\ifx \MyPersonalMacro \undefined \else
We inserted equation \eqref{eq:label} and Figure \ref{fig:figure} in
this document.
The reference to Maxwell equations \eqref{eq:maxwell} works only if
compiled on Linux via \texttt{ocgtools-preview.sh} (called from
\texttt{ocgtools-test.sh} automatically with correct parameter). \fi
