% \section{Introduction}
%
%    The \pkg{aeb\_pro} package that access the `advanced' features of the PDF
%    specification. It uses various combinations of driver-dependent code,
%    \textbf{pdfmark} code, and JavaScript methods and techniques that require
%    \app{Acrobat~7.0 Professional} for document assembly. The package provides
%    the \textbf{AeB Control Central}. Use the \textbf{AeB Control Central} to
%    load all your Acro\negthinspace\TeX packages in the correct order. See
%    additional remarks in the titled paragraph \textbf{\nameref{para:beast}}

%    \paragraph*{On the nature of the beast}\label{para:beast} There are three types of commands
%    (and environments) in this package: (1) commands that use driver dependent
%    code, available to all workflows; (2) commands that depend on the
%    \textbf{pdfmark} operator, available only to the \app{dvips/Distiller}
%    workflow; and (3) commands that use `post-PDF creation' methods that rely
%    on the document author having the full \app{Acrobat} application.
%
%    For the workflow \app{dvips/Distiller}, all three code types are
%    available; for whose authors that prefer \app{pdflatex/\penalty0
%    lualatex/\penalty0 xelatex}, but \emph{do not have} the full
%    \texttt{Acrobat} product, the commands of type~(1) are available through
%    the \opt{nopro} option. Finally, for authors that prefer
%    \app{pdflatex/\penalty0 lualatex/\penalty0 xelatex} and \emph{do have}
%    \app{Acrobat}, the commands of type~(1) and~(3) are available through
%    the \opt{useacrobat} option.

% \subsection{The \texttt{useacrobat} option}

% \app{pdflatex}, \app{xelatex}, etc, we shall let them but under

% The normally \pkg{aeb\_pro} will brings in all the
% code that would require the use of the \app{Distiller} and \app{Acrobat Pro},

% no involve layers or post-PDF creation methods.

%    \xBld[true|false|print=(true|false)]
%        {<layer_name>}<content in layer>\eBld
%\end{verbatim}
%The description of the optional parameters follows:
%\begin{itemize}
%  \item \texttt{true}\IndexKey{true}: Inserting \texttt{true} as an optional argument causes the layer to be initially visible.
%  \item \texttt{false}\IndexKey{false}: Inserting \texttt{false} as an optional argument causes the layer to be initially hidden.
%  The default is \texttt{false}, so if no \texttt{true} or \texttt{false} argument is passed as an optional argument,
%  the layer will be initially hidden.
%  \item \texttt{print}\IndexKey{print}: This key allows you to set the printability of the layer: If \texttt{print=true},
%  the layer \emph{always prints}, no matter if it is visible or not. If \texttt{print=false},
%  the layer \emph{never prints}, no matter if it is visible or not. If the print key is not specified,
%  then the layer will print if visible, otherwise, it does not print. Normally, the \texttt{print}
%  key is not specified, and the layer is printed if visible.

% \subsection{In Support of Anime using Layers}
% Using layers, it is possible to create a sort of animation (anime).  The following
% are some rudimentary methods for creating anime. An example can be found below,
% as well as in \texttt{aebpro\_ex4.tex}.
%

%    \begin{macro}{\DeclareAnime}
% The command \cs{animeBld} increments \texttt{ocSeq}, and names
% the layer so that the JS can run through the layers in an orderly way.
%
% \cs{DeclareAnime} takes three arguments, the anime base name, the speed at which
% you wish the anime to be played, and the number of frames of this animation. It
% saves these three parameters in macros, and creates \cs{animBldName}, which is used
% in the creation of the anime. See example file \texttt{aebpro\_ex4.tex}.
%    \begin{macrocode}
\newcommand{\animeBld}[1][]{\stepcounter{ocSeq}%
    \xBld[#1]{\animBldName}}
\newcounter{ocSeq}
%    \end{macrocode}
% (10/01/01) We give an animation the special `\texttt{anime!!}' prefix, so JavaScript can identify
% animation layers.

%  {\CMD{ahyperref}, \CMD{ahyperlink}, \CMD{ahyperextract}}}
%
% The \cs{ahyperref} command is for linking between parent and child, or
% between child and child. \cs{ahyperref} takes three arguments, the first optional
% and the second two required.
%\begin{verbatim}
%   \ahyperref[<optargs>]{<label>}{<text>}
%\end{verbatim}
% where \texttt{<label>} is one defined by either \cs{autolabelNum} or \cs{labelName}. The
% \texttt{<text>} is the text to be typeset around the link. The optional arguments are defined
% and described below.
% \begin{itemize}
%   \item \verb!goto=p2c,c2p,c2c!: The type of jump, parent to child, child to parent, and child to
%         child. The default is \texttt{p2c}
%   \item \texttt{page=<number>}: the page of the embedded document to jump to. Default is \texttt{0}
%   \item \texttt{view=<value>}: the view to be used for the jump. Default is \texttt{Fit}
%   \item \texttt{dest=<string>}: jump to a named destination. When this key has a value, the values
%         of the keys \texttt{page} and \texttt{view} are ignored.
%   \item \verb!open=usepref|new|existing!: open the attachment according to the user preferences,
%         a new window, or the existing window. The default is \texttt{userpref}
%   \item \verb!border=visible|invisible!: Determines whether a visible rectangle appears around the
%         link. The default is \texttt{invisible}
%   \item \verb!highlight=none|invert|outline|insert!: How the viewer highlights the link when the
%         link is clicked.  The default is \texttt{invert}.
%   \item \texttt{bordercolor=r g b}: The color of the border when it is visible. The default is black.
%   \item \verb!linestyle=solid|dashed|underlined!: The line style of the border when it is visible.
%         The default is \texttt{solid}
%   \item \texttt{textcolor=<color>}: the color of the text in the hypertext link. An empty
%           value is equivalent to \cs{normalcolor}.
%   \item \verb!linewidth=thin|medium|thick!: The line width when the border is visible. When invisible,
%         this is set to a width of zero. The default is \texttt{thin}
%   \item \texttt{preset=\cs{presetCommand}}: A convenience key. You can define some preset values, like so
%\begin{verbatim}
%\def\preseti{bordercolor={0 0 1},highlight=outline,border=visible,%
%             linestyle=dashed}
%\end{verbatim}
%           Then you can say, for example,
%\begin{verbatim}
%\ahyperref[dest={target1-s:intro},preset=\preseti]{target1}{Jump!}
%\end{verbatim}
% \end{itemize}

% \section{Document Assembly Methods}
%    Special ``helper'' commands and one environment are defined to take advantage of \app{Acrobat}'s extensive
%    library of security restricted methods. It is assumed the document author has properly
%    installed \texttt{aeb\_pro.js}.
%
% \subsection{The \texttt{docassembly} environment}
%
%    \begin{environment}{docassembly}
% This is a wrapper environment for the \texttt{execJS} environment of the
% \textsf{insDLJS} Package. Place JavaScript lines in this environment and
% the script will execute one time after the PDF has been created and opened
% in \app{Acrobat Pro} for the first time.
%    \begin{macrocode}
\newenvironment{docassembly}{%
\execJS{docassembly}
}{\endexecJS}
%    \end{macrocode}
%    \end{environment}
% \subsection{Supported Assembly JS API}
%
%    These are convenience commands -- called JavaScript helper commands -- to
%    executing security restricted JavaScript. The JS methods are defined in the
%    \texttt{aeb\_pro.js} file, kept as folder JavaScript. These commands are
%    executed in a verbatim environment where `\verb!\!' is still the escape
%    character. Each of the JavaScript helper commands expects a left
%    parenthesis `\texttt{(}' following the command name \emph{on the
%    same line} as the command name.\footnote{This requirement is consistent with JavaScript function usage.}
%    See the example below for correct usage.
%\begin{verbatim}
%\begin{docassembly}
%\addWatermarkFromFile({
%    bOnTop:false,
%    cDIPath:"/C/AcroTeX/AcroPackages/ManualBGs/Manual_BG_Print_AeB.pdf"
%});
%\end{docassembly}
%\end{verbatim}
% For each of the methods below, see the \textsl{JavaScript for Acrobat API Reference}.
%
%\medskip\noindent The command \cs{theDocObject} is normally set to \texttt{this}, meaning
% the current document. You may need to set it to some other doc object if you are trying to
% access a doc object other than the current one.
% \par\medskip\noindent
% Revised all these function that use \cs{theDocObject}; the revisions allow you to change
% the use of \cs{theDocObject}. The following are support commands for changing \cs{theDocObject}
% from within the \texttt{docassembly} environment.
% \changes{v2.5}{2016/08/03}{Revised all these function that use \string\cs{theDocObject}.}
%    \begin{macro}{\chngDocObjectTo}
%    All the JavaScript helper commands use \cs{theDocObject}, which is defined to be the \texttt{this}
%    object. To change it within the \env{docassembly} environment is difficult. The next command
%    aids in that problem.
%    \begin{macrocode}
\let\ap@mrk\@empty
\def\ap@gobtocomma#1,{}
\providecommand\chngDocObjectTo[2]{%
    \def#1##1\ap@mrk{#2,\ap@gobtocomma##1}}
%    \end{macrocode}
%    \end{macro}
%    The above defines a new command given by \texttt{\#1}. The command has one argument which is all content
%    up to the terminating mark \cs{ap@mrk}. The trick to removing \cs{thisDocObject} and replacing it with
%    \texttt{\#2}, in the above definition, we insert `\texttt{(\#2}' followed by \cs{ap@gobtocomma}, which absorbs
%    \cs{thisDocObject,} (absorbs everything through the first comma), followed by all content (\texttt{\#\#1}); the second \cs{@gobble} absorbs the left
%    parenthesis that opens the argument.
%    \begin{macrocode}
\def\ap@TF{aebTrustedFunctions}
%    \end{macrocode}
% An example of usage of \cs{chngDocObject} is \verb~\chngDocObjectTo{\newDO}{doc}~
% expanded above the \texttt{docassembly} environment. Later, we can say,
%\begin{verbatim}
%   \chngDocObjectTo{\newDO}{doc}
%   \begin{docassembly}
%   ...
%   \docSaveAs\newDO({ cPath: _path });
%   ...
%   \end{docassembly}
%\end{verbatim}
%That is, it is placed immediately after any of the commands below that uses \cs{theDocObject}.
%    \begin{macro}{\theDocObject}
%    This command is used in the definition of all JavaScript helper commands, as seen in the
%    definition of \cs{DeclareJSHelper} below. It is set to the doc object \texttt{this}. It can
%    be changed using \cs{chngDocObjectTo}, as described above.
%    \begin{macrocode}
\def\theDocObject{this}
%    \end{macrocode}
%    \end{macro}
%    \begin{macro}{\DeclareJSHelper}

%    \end{macrocode}
%    For example, we declare |\DeclareJSHelper{\docSaveAs}{aebDocSaveAs}| below, the declaration defines a new command,
%    \cs{docSaveAs}:
%\begin{verbatim}
%    \def\docSaveAs#1({\ap@TF(#1\theDocObject,aebDocSaveAs,\ap@mrk}}
%\end{verbatim}
%    Note that the argument of \cs{docSaveAs} is delimited by the left parenthesis, thus \texttt{\#1} is everything through that opening
%    parenthesis. This approach allows more flexibility in the definition, there can be spaces following the
%    command name |\docSaveAs ({path: _path})|, for example.
%    \end{macro}
%    \begin{macro}{\retnAbsPathAs}\hskip-\marginparsep\texttt{(\ameta{js-var})}
%    Several methods require an absolute path to the current folder. The code is,

% \subsection{Pre-docassembly Commands}
%
% In this section, we'll gather some ``useful'' commands
% for combining several \texttt{docassembly} tasks together.
% The \texttt{docassembly} environment is a partial-verbatim
% environment, expansion is severely limited. (\verb!\! is
% the escape sequence, but \verb!{}! are no longer grouping characters; hence
% macros with no argument can be expanded.) The trick is to expand
% before placing the lines in the \texttt{docassembly} environment.
%
% \subsubsection{Import and Place Images}
%
%    \begin{macro}{\declareImageAndPlacement}
% With this command, the document author can import images (icons)
% into the document give them names, and associate the image with a
% push button, specifically, once created by the \cs{placeImage}
% command, defined below. The command may be used several times, once
% for each image (icon) that is to be embedded and placed.
%
% This command should appear outside the \texttt{docassembly} environment.
%
% In the example below, give an image a name manAvatar, specify the
% path (\texttt{man1.pdf}) and list the names of the push buttons
% (ones created by \cs{placeImage}) where this image is to appear as
% a button face.

% If there is no optional argument, the default is 0, for the normal appearance state.
