\section{Introduction}

Beginning with Version 5.0, ``Acrobat Distiller allows a Postscript
language program to specify that a given set of graphical operations
should be encapsulated and treated as a single object. The pdfmarks
\textbf{BP} (Begin Picture) and \textbf{EP} (End Picture) enclose a
set of graphic operations. The \textbf{SP} (Show Picture) pdfmark
indicates where to insert an object (which may be inserted in more
than one place).''\,\footnote{Section 4.6.1 of the \textit{pdfmark
Reference Manual}, Technical Note \#5150, Version 5.0} This is the
approach taken by this package.

\pkg{GraphicxSP} includes commands for embedding an EPS graphic (using the
\textbf{BP} and \textbf{EP} pdfmark operators) in a PDF derived from
a {\LaTeX} source and for displaying the graphic, possibly multiple
times. For documents that use the same graphic multiple times (for
backgrounds, watermarks, company logos, appearances for form fields,
etc.) using \pkg{GraphicxSP} will (greatly) reduce the size of the
PDF.\footnote{The amount of reduction in file size depends on how
many times a particular graphic is repeatedly used.}

The PDF 1.4 (Acrobat version 5.0) introduces the notion of
transparency into the Adobe imaging model. Support for transparency
through the pdfmark paradigm does not appear until Version
6.0.\,\footnote{Section 4.6.1 of the \textit{pdfmark Reference
Manual}, Technical Note \#5150, Version 6.0, page~33.} This package
also supports transparency feature through the
\textbf{SetTransparency} pdfmark.

\pkg{GraphicxSP}, as the name might suggest, is an extension of the
graphicx package. Functionality for \pkg{GraphicxSP} is accessed through
the \cs{includegrapics} command. Additional key-values for the
\cs{includegrapics} command are defined that support the use
\pkg{GraphicxSP}.

\section{Requirements}

{\LaTeX}, PDF, and transparency requirements are discussed in this section.

\subsection{{\LaTeX} package requirements}

This package requires the \pkg{graphicx} package (by D. P. Carlisle and S. P. Q.
Rahtz), the \pkg{eso-pic} package (by Rolf Niepraschk) and the \pkg{everyshi}
package (by Martin Schr\"oder). \pkg{GraphicxSP} redefines a few commands of the
first two packages: the \pkg{graphics}/\pkg{graphicx} package commands \cs{Gin@setfile}
and \cs{Gin@getbase} are redefined, as is the \pkg{eso-pic} command \cs{@ShipoutPicture}.

\pkg{AeB} (Acro\negthinspace\TeX{} eDucation Bundle) is not a required
package, but to successfully compile the example
\texttt{grxsp\_forms\_aeb.tex}, you need the latest \pkg{AeB} as some
modification to the eforms package were made. See
\mlurl{http://www.math.uakron.edu/~dpstory/graphicxsp.html} for the latest
version.

\subsection{PDF creator requirements}

The big restriction on this package is the requirement to use
\textbf{Acrobat Distiller} (version 5.0, or version 6.0 for transparency).
The package was developed using Acrobat Distiller 8.1. The package supports the
creation of Postscript using \app{dvips} and \app{dvipsone}.

Though distiller is required, there is no reason why, however, this
package can't be modified to work for any PDF creator that supports
the pdfmark; in particular, I invite anyone to extend this package
to \app{GhostScript}.

\subsection{Transparency requirements}

To get the transparency effect, \app{Acrobat Distiller} version 6.0 or
later is required. The default setting of the distiller does not
support the \textbf{SetTransparency} pdfmark; it is necessary to
edit the \texttt{.joboptions} file.

\newtopic\noindent
The procedure for editing \texttt{.joboptions} to support transparency is as follows:
\begin{enumerate}
    \item Start Acrobat Distiller

    \item From the Default Settings list, select the setting you want to
        edit, usually, this will be the \texttt{Standard} job options.
    \item Select \textsf{Settings\;>\;Edit\;Adobe\;PDF\;Settings\;(Ctrl+E)}
        from the distiller menu.
    \item Click the \texttt{SaveAs} button at the bottom of the
        \texttt{Adobe PDF Settings} dialog box. Save your
        \texttt{.jobsettings} file under a new name, say
        \texttt{Standard\_transparency} and make a note of where the
        distiller saves this file.
    \item With your favorite text editor, navigate to the folder where you
        saved your new \texttt{.joboptions} file, and open it in your
        editor.
    \item Look for the line \texttt{/AllowTransparency false}, change
        \texttt{false} to \texttt{true} so that it now reads
        \texttt{/AllowTransparency true}. Save the changes and close the
        file.
    \item Use this \texttt{.joboptions} file,
        \texttt{Standard\_transparency} for example, whenever you distill
        with transparency pdfmarks.  If your {\LaTeX} file uses
        transparency, and you are using a \texttt{.joboptions} file with
        \texttt{/AllowTransparency false}, distillation will fail and the
        distiller log should say
\begin{Verbatim}[fontsize=\small]
%%[Error: The Postscript contains Transparency pdfmark, job aborted.]%%
%%[ /AllowTransparency is false in job option settings.]%%
%%[ Error: undefined; OffendingCommand: pdfmark;
    ErrorInfo: Transparency Group ]%%
\end{Verbatim}
This suggests that you should use your \texttt{.joboptions} file that supports transparency!

\end{enumerate}

\section{Options of this package}

Currently, there is a minimal of package options

\begin{itemize}
\item \texttt{dvips}: Use this option if you are a user of most any other
    {\TeX} systems available to the community.
\item \texttt{dvipsone}: Use this option if you are a user of the Y{\small\&}\!Y
    {\TeX} system to create your Postscript file.
\item \texttt{preview}: The dvi previewers are designed to show a preview
    of the graphic, these previewers know nothing about the \textbf{SP}
    pdfmark (Show Picture). If you use the \texttt{preview} option, a
    \cs{fbox} is placed around all graphics inserted by the
    \pkg{GraphicxSP} package. This option sets a boolean switch,
    \cs{ifpreview} to true. You are free to locally set this switch to get
    the \cs{fbox} to appear, use include \cs{previewtrue} in your document,
    or, to turn the preview off again, type \cs{previewfalse}.
\item \texttt{showembeds}: As just mentioned, dvi previewers are
    designed to preview graphics; consequently, the graphic files
    embedded by \pkg{GraphicxSP}, will have a preview as well. The
    embedding command \cs{embedEPS} is required to appear only in
    the preamble, so the preview for this embedded graphics always
    appears on the first page. \pkg{GraphicxSP} covers these embedded
    files using a white \texttt{colorbox}; content and other
    graphics are placed on top of the white \texttt{colorbox}. Using
    the \texttt{showembeds} will cause this white color box not to
    be created, hence, you can see the dvi preview of the embedded
    graphics, stacked one on top of the other.
\item \texttt{draft}: Similar to the option of the same name in the
    graphicx package. Instead of displaying an image, a rectangular
    box is displayed with the name of the graphic in its interior.
\item \texttt{shownonames}: If this option is chosen along with
    the \texttt{draft} option, the name of the graphic is not displayed.
\end{itemize}

\section{The \texorpdfstring{\protect\pkg{GraphicxSP}}{GraphicxSP} commands}

In this section we present the new commands defined in the \pkg{GraphicxSP} package.

\subsection{Embedding commands}

Before we can show a graphic, we first must embed it using the
\cs{embedEPS} command.
\bVerb\takeMeasure{\string\embedEPS[\meta{key-values}]\darg{\meta{name}}\darg{\meta{path}}}
\begin{dCmd}[commandchars=!()]{\bxSize}
\embedEPS[!meta(key-values)]{!meta(name)}{!meta(path)}
\end{dCmd}
\endgroup
\CmdLoc This command is restricted to the preamble.

\PD The parameters are as follows:
\begin{enumerate}
\item The first optional parameter takes key-value pairs:
\begin{itemize}
    \item \texttt{hiresbb}: This is a key from the graphicx package.
        When this key is present, graphicx will look for the high
        resolution bounding box; otherwise, is looks for the
        bounding box.
    \item \texttt{transparencyGroup}: Use this key if the embedded
        graphic is to be used with transparency. The key is normally
        used by itself, but it can be given values, a good old-fashion
        reading of Chapter 7 on Transparency in the PDF Reference, sixth
        edition, version 1.7, is necessary.
\end{itemize}
\item The second parameter \meta{name} is the symbolic name for
the graphic. This symbolic name must be unique to the document (or
distiller will crash); \pkg{GraphicxSP} will stop compilation if two
embedded EPS files are given the same name.
\item The third parameter is the path to the graphic, an EPS
graphic. The graphic can be in the current folder, or on the
graphics search path. The same rules hold here as in the graphicx
package.
\end{enumerate}
For example,
\bVerb\takeMeasure{\string\embedEPS[hiresbb,transparencyGroup]\darg{myBestPic}\darg{graphics/AdobeDon}}
\begin{dCmd*}[commandchars=!()]{\bxSize}
\embedEPS[hiresbb,transparencyGroup]{myBestPic}{graphics/AdobeDon}
\end{dCmd*}
\eVerb
When a file is embedded, certain parameters are saved and are
available for use by the document author. Each of the commands below
take the symbolic name, \meta{name} of the graphic as their only
argument.
\begin{itemize}
\item \cs{bboxOf\darg{\meta{name}}}: The dimensions of the bounding box,
    \texttt{llx} \texttt{lly} \texttt{urx} \texttt{ury}, of the graphic
    with symbolic name \meta{name}. The individual values of this bounding box
    can be accessed by the next four commands.

\item \cs{llxOf\darg{\meta{name}}}: The lower left x-coordinate of the
    (high res) bounding box as read by graphicx.

\item \cs{llyOf\darg{\meta{name}}}: The lower left y-coordinate of the
    (high res) bounding box as read by graphicx.

\item \cs{urxOf\darg{\meta{name}}}: The upper left x-coordinate of the
    (high res) bounding box as read by graphicx.

\item \cs{uryOf\darg{\meta{name}}}: The upper left y-coordinate of the
    (high res) bounding box as read by graphicx.

\item \cs{heightOf\darg{\meta{name}}}: The height of the graphic, based on
    the bounding box information, \cs{uryOf\darg{\meta{name}}} -
    \cs{llyOf\darg{\meta{name}}}.

\item \cs{widthOf\darg{\meta{name}}}: The width of the graphic, based on
    the bounding box information, \cs{urxOf\darg{\meta{name}}} -
    \cs{llxOf\darg{\meta{name}}}.
\end{itemize}
Each expands to a number representing Adobe points. To convert these
numbers for use by {\TeX} just add the suffix \texttt{bp}, e.g., in
{\TeX} space, the height of the graphic is \cs{heightOf\darg{\meta{name}}bp}.

These commands are useful when creating variations on an
\cs{embedEPS} graphic using the \texttt{createImage} environment
defined below, or for creating form fields with an \cs{embedEPS}
graphic as an appearance.

The \cs{embedEPS} command is designed for graphics that are in an exterior
EPS file. You can also define a graphic, or image, using raw
Postscript using the \Indextt{createImage} environment.

%\bVerb\takeMeasure{\string\begin\darg{createImage}[\meta{key-values}]\darg{\meta{bbox}}\darg{\meta{name}}}
%\begin{dCmd}[commandchars=!()]{\bxSize}
%\begin{createImage}[!meta(key-values)]{!meta(bbox)}{!meta(name)}
%    !meta(postscript code)
%\end{createImage}
%\end{dCmd}
%\eVerb


\bVerb\takeMeasure{\string\begin\darg{createImage}[\meta{key-values}]\darg{\meta{bbox}}\darg{\meta{name}}}
\begin{minipage}[c]{\linewidth}
\begin{minipage}[c]{\bxSize}
\begin{dCmd}[commandchars=!()]{\bxSize}
\begin{createImage}[!meta(key-values)]{!meta(bbox)}{!meta(name)}
    !meta(postscript code)
\end{createImage}
\end{dCmd}
\end{minipage}\hfill
\begin{minipage}[c]{\linewidth-(\bxSize)}
\setDisplayNumber\label{createImg}
\end{minipage}
\end{minipage}\medskip
\eVerb The \env{createImage} environment defines a command \cs{\meta{name}} that expands to
\meta{name}. If \cs{\meta{name}} is already defined, a message appears in the log to that effect.
Normally \meta{name} consists of non-active characters; however, if other characters are used,
the command \cs{csOf\darg{\meta{name}}} can be used. The \cs{\meta{name}} command was created to support
the \pkg{icon-appr} package.

\PD The parameters are as follows:
\begin{enumerate}
\item The first optional parameter takes key-value pairs:
\begin{itemize}
    \item \texttt{transparencyGroup}: Use this key if the embedded
        graphic is to be use with transparency. The key is normally
        used by itself, but it can be given values, a good
        old-fashion reading of Chapter 7 on Transparency in the PDF
        Reference, sixth edition, version 1.7, is necessary.
\end{itemize}
\item The second parameter, \meta{bbox}, is the bounding box of the
image being created.
\item The third parameter \meta{name} is the symbolic name for
the graphic. This symbolic name must be unique to the document (or
distiller will crash); \pkg{GraphicxSP} will stop compilation if two
embedded EPS files are given the same name.
\end{enumerate}
The following image appears in one of the demo files of this package, and is code
written many years ago for a tic-tac-toe game in PDF.
\begin{Verbatim}
\begin{createImage}{0 0 100 100}{xO}
.7529 setgray 0 0 100 100 rectfill 1 setgray 2 2 moveto 2 98 lineto
98 98 lineto 96 96 lineto 4 96 lineto 4 4 lineto fill 0.34 setgray
98 98 moveto 98 2 lineto 2 2 lineto 4 4 lineto 96 4 lineto
96 96 lineto fill 0 setgray 22.5 22.5 moveto 1 0 0 setrgbcolor
/Helvetica 72 selectfont (O) show
\end{createImage}
\end{Verbatim}

\begin{Verbatim}
\embedEPS[hiresbb,transparencyGroup]{myBestPic}{graphics/AdobeDon}
\end{Verbatim}
we can then manipulate this image a little
\begin{Verbatim}
\begin{createImage}{\bboxOf{myBestPic}}{upsideDownAD}
     0 \heightOf{myBestPic} rmoveto
     currentpoint translate
     1 -1 scale [ {myBestPic} /SP pdfmark
\end{createImage}
\end{Verbatim}
Notice that we reposition the graphic to fit inside the bounding box.

I don't mean to get ahead of myself, but you can introduce transparency as well.

\begin{Verbatim}
\begin{createImage}{\bbox{myBestPic}}{transparentAD}
    [ /ca .3 /SetTransparency pdfmark
    [ {myBestPic} /SP pdfmark
\end{createImage}
\end{Verbatim}
All these examples will appear again below when \cs{includegraphics} and \cs{insertEPS}
are discussed.

\newtopic\noindent
The commands \cs{llxOf}, \cs{llyOf}, \cs{urxOf}, \cs{uryOf}, \cs{bboxOf},
\cs{heightOf} and \cs{widthOf} are also defined for images created by the
\texttt{createImage} environment.


\subsection{Inserting graphics commands}

Once we have embedded our graphics using \cs{embedEPS} or create a
new image or modified an old image using the \texttt{createImage}
environment, we can display them to our heart's content. There are two
commands for displaying a embedded graphic, \cs{includegraphics} and
\cs{insertEPS}.

\bVerb\takeMeasure{\string\includegraphics[name=\meta{name},\meta{key-values}]\darg{\meta{path}}}
\begin{dCmd}[commandchars=!()]{\bxSize}
\includegraphics[name=!meta(name),!meta(key-values)]{!meta(path)}
\insertEPS[!meta(key-values)]{!meta(name)}
\end{dCmd}
\endgroup

\PD The \meta{name} key is required in the \cs{includegraphics}
command, the value is the symbolic \meta{name} of the graphic to
be used. When the name key is used, the \meta{path} parameter is not
used in \pkg{GraphicxSP} and can actually be empty; if the name key is not
specified, then \cs{includegraphics} behaves just like it always
does, includes the file in the document and displays it. Because
\meta{path} is not used with SP graphics, \pkg{GraphicxSP} offers
\cs{insertEPS} as an alternative; here the \meta{name} is given as the
second argument. The \meta{key-values} are described next.

\KVP Both commands take all the key-values of the \cs{includegraphics} command, plus
a few more:
\begin{enumerate}
    \item \texttt{name=\meta{name}}: The symbolic name (\meta{name}) for
        the graphic, it is required with the \cs{includegraphics} command,
        and is ignored in the \cs{insertEPS} command. In the later command,
        \meta{name} is entered as the second argument.

    \item \texttt{transparency=\meta{key-values}}: Here you can enter
    various key-value pairs for setting transparency. These
    keys-values are listed in the pdfmark Reference in the section
    on the SetTransparency pdfmark. Of the ones listed, I've only explored
    \textbf{BM}, \textbf{ca} and \textbf{CA}. The following come from the pdfmark Reference on these three:
    \begin{itemize}
        \item \textbf{CA}: Current stroking alpha constant,
        specifying the constant shape or constant opacity value to
        be used for stroking operations. Default is 1.0.
        \item \textbf{ca}: Same as CA, but for nonstroking operation. Default is 1.0.
        \item \textbf{BM}: Current blend mode. Default is Normal.
            Other blend modes are Normal, Multiply, Screen,
            Darken, Lighten, ColorDodge, ColorBurn, HardLight,
            SoftLight, Difference, Exclusion. See the PDF
            Reference for a description of these.

    \end{itemize}
    The most useful of these is \textbf{ca}, and it is illustrated
    in the demo files and well as here.

    \item[] \textbf{Example:} \verb!transparency={/ca .3 /BM/Normal}!

    \item \texttt{presp=\meta{postscript}}: This allows you to insert
        Postscript commands just before \textbf{SP} pdfmark.
    \item \texttt{postsp=\meta{postscript}}: This allows you to insert
        Postscript commands just after \textbf{SP} pdfmark.
\end{enumerate}
The latter two key-values can be used to create special effects, as illustrated below.

\subsection{Examples}

%\previewtrue

\begin{center}
\includegraphics[name=myBestPic,width=1in]{}\\
\small\verb!\includegraphics[name=myBestPic,width=1in]{}!
\end{center}

Below is the image created not from a EPS file, but from Postscript language code.

\begin{center}
\includegraphics[name=xO,width=1in]{}\\
\small\verb!\includegraphics[name=x0,width=1in]{}!
\end{center}

The \meta{path} argument can remain empty as it is not used when the name key is
present. Now, we'll switch over to the shorter \cs{embedEPS} command.

Here is the image created earlier using the \texttt{createImage} environment. The same effect
can be done with \cs{scalebox}.

\begin{center}
\insertEPS[width=1in]{upsideDownAD}\\
\verb!\insertEPS[width=1in]{upsideDownAD}!
\end{center}

Below is the transparent image created using the \texttt{createImage} environment. The same effect
can be done by setting the \texttt{transparency} key set to \verb!{/ca .3}!. The background is white
and it is this white background you see showing through the image.

\begin{center}
\insertEPS[width=1in]{transparentAD}\\
\verb!\insertEPS[width=1in]{transparentAD}!
\end{center}



Next, we set the \texttt{transparency} key to an opacity value ranging from 70\% on the left (\texttt{/ca .7})
to 30\% on the right (\texttt{/ca .3}), and place a colorful background under the
image so you can see the transparency of the image.

\begin{center}\previewfalse
\insertEPS[width=\linewidth,height=80pt]{myBG} %transparency={/ca .3 /BM/Normal},
\smash{\raisebox{15pt}{\makebox[\linewidth][c]{%
\insertEPS[width=1in,transparency={/ca .7}]{myBestPic}\hfill
\insertEPS[width=1in,transparency={/ca .6}]{myBestPic}\hfill
\insertEPS[width=1in,transparency={/ca .5}]{myBestPic}\hfill
\insertEPS[width=1in,transparency={/ca .4}]{myBestPic}\hfill
\insertEPS[width=1in,transparency={/ca .3}]{myBestPic}}}}
\small\verb!transparency={/ca .7}...transparency={/ca .3}!
\end{center}

We can rotate the image using the usual graphicx controls, as below, or we can
use \cs{rotatebox}.

\begin{center}
\insertEPS[width=1in,angle=45]{myBestPic}\\
\small\verb!\insertEPS[width=1in,angle=45]{myBestPic}!
\end{center}

Any of the keys of \cs{includegraphics} can be used to manipulate
the image. The images can also be manipulated using other graphicx
commands, \cs{resizebox}, \cs{scalebox} and \cs{rotatebox}, for
example.

Finally, here is an example of the use of \texttt{presp} and \texttt{postsp}:

\def\mypreSP#1{%
    newpath
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    Draw_Ellipse
    clip
    newpath
}
\def\mypostSP#1{%
    gsave
    [ /ca .4 /SetTransparency pdfmark
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    Draw_Ellipse
    0.4 0.7 1 setrgbcolor
    fill
    grestore
    gsave
    [ /CA .5 /BM/Screen /SetTransparency pdfmark
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    Draw_Ellipse
    40 setlinewidth
    0.4 0.7 1 setrgbcolor
    stroke
    grestore
}

\begin{center}
\includegraphics[name=myBestPic,width=1.5in,
    presp={\mypreSP{myBestPic}},
    postsp={\mypostSP{myBestPic}}]{myBestPic}
\end{center}
The \texttt{presp} code is

\begin{Verbatim}[fontsize=\small]
\def\mypreSP#1{%
    newpath
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    Draw_Ellipse
    clip
    newpath
}
\end{Verbatim}
and clips the image in the shape of an ellipse. In this case, the
image is almost square, so the image is almost circular.

The \texttt{postsp} is

\begin{Verbatim}
\def\mypostSP#1{%
    gsave
    [ /ca .4 /SetTransparency pdfmark
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    Draw_Ellipse
    0.4 0.7 1 setrgbcolor
    fill
    grestore
    gsave
    [ /CA .5 /BM/Screen /SetTransparency pdfmark
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    \widthOf{#1} 2 div \heightOf{#1} 2 div
    Draw_Ellipse
    40 setlinewidth
    0.4 0.7 1 setrgbcolor
    stroke
    grestore
}
\end{Verbatim}
After clipping the image itself, and displaying the image, we then
cover the image with an ellipse the same size, set the transparency
to 40\% opacity and fill, giving the image a bluish haze. Next, draw
the ellipse again and stroke it with a line 40 points wide. Give it an
opacity of 50\%, so \texttt{AdobeDon} will shine through.


\section{Special techniques for form appearances}\label{forms}

In addition to using embedded graphics to display an image with
\cs{includegraphics} or \cs{insertEPS}, these images can be
used as appearances for form fields. Examples of a push button and
checkbox can be found in the demo files, here reproduce the push
button example.

For this techniques, the eforms package is required. The forum
support of hyperref may not support the \textbf{AP} key the way
eforms does.

In the preamble, we have
\begin{Verbatim}
\begin{createImage}{\bboxOf{myBestPic}}{nAdobeDon}
    [ {myBestPic} /SP pdfmark
\end{createImage}

\begin{createImage}{\bboxOf{myBestPic}}{rAdobeDon}
    [ /ca .5 /SetTransparency pdfmark
    [ {myBestPic} /SP pdfmark
\end{createImage}

\begin{createImage}{\bboxOf{myBestPic}}{dAdobeDon}
    [ /ca .3 /SetTransparency pdfmark
    [ {myBestPic} /SP pdfmark
\end{createImage}
\end{Verbatim}

We use \cs{bboxOf} to set the bounding boxes to be the same as the
original \texttt{myBestPic} image, and define a normal, rollover and
down appearances for the button (\texttt{nAdobeDon},
\texttt{rAdobeDon} and \texttt{dAdobeDon}), respectively. We use
various opacity settings for the appearances.

The button code is

\begin{Verbatim}[xleftmargin=\parindent,fontsize=\small]
\resizebox{.5in}{!}{\pushButton[\BC{}\BG{}\S{S}
  \A{\JS{app.alert("AcroTeX rocks the world!"); this.dirty=false;}}
  \autoCenter{y}\TP{1}\FB{true}
  \I{nAdobeDon}\IX{dAdobeDon}\RI{rAdobeDon}
]{pbAdobeDon}{\widthOf{myBestPic}bp}{\heightOf{myBestPic}bp}}
\end{Verbatim}
See the \pkg{eforms} manual for details of these key-value pairs.\smallskip

Finally, the button looks like this: \resizebox{.5in}{!}{\pushButton[%
    \autoCenter{y}\BC{}\BG{}\S{S}
    \A{\JS{app.alert("AcroTeX rocks the world!");this.dirty=false;}}
    \I{nAdobeDon}\IX{dAdobeDon}\RI{rAdobeDon}\TP{1}\FB{true}
]{pbAdobeDon}{\widthOf{myBestPic}bp}{\heightOf{myBestPic}bp}}\par\smallskip\noindent
In light of the discussion following display~\eqref{createImg} on page~\pageref*{createImg}, the code for the above
button could have been,
\begin{Verbatim}[xleftmargin=\parindent,fontsize=\small]
\resizebox{.5in}{!}{\pushButton[\BC{}\BG{}\S{S}
  \A{\JS{app.alert("AcroTeX rocks the world!"); this.dirty=false;}}
  \autoCenter{y}\TP{1}\FB{true}
  \I{\nAdobeDon}\IX{\dAdobeDon}\RI{\rAdobeDon}
]{pbAdobeDon}{\widthOf{myBestPic}bp}{\heightOf{myBestPic}bp}}
\end{Verbatim}
When using \textbf{SP} images for form fields in this way, the images
\textbf{must always pass} through a \texttt{createImage} environment where the
bounding boxes can be precisely set, in the verbatim listing above,
note \verb!\bboxOf{myBestPic}! sets the bounding box. The reason you
can't use an embedded image directly is that the embedded image has
had its bounding box reset to an enormous value. See the
documentation in graphicxsp.dtx for more details.

The dimensions of the push button are the last two arguments of the
\cs{pushButton} command and are set to \verb!\widthOf{myBestPic}bp!
and \verb!\heightOf{myBestPic}bp!, (Note the use of the \texttt{bp}
dimension.)  We then resize this field using \cs{resizebox}! Very
swave how the graphicx and \pkg{GraphicxSP} work together.

\section{Tips}

Since you are using distiller, you have Acrobat as well. Try using
the PDF Optimizer (\texttt{Advanced > PDF Optimizer} menu) to
further reduce the size of the file. If you have Acrobat Pro 8.0,
you can do a Save As, by selecting Adobe PDF Files, Optimized from
the Save as type list. This is the same as using the PDF Optimizer.

An example of the savings is this manual, after distillation
document size was 176.6 KB, after the PDF Optimizer was done, the
file size was 113.6 KB. That's a reduction of 63 KB or that's a
reduction of 38\,\%. For some of the demo files, the reduction is
much more dramatic since the images are used and re-used many more
times than in this document.


\section{\texorpdfstring{\protect\pkg{GraphicxSP}}{GraphicxSP} example files}

The example files can be found in the \texttt{examples} folder of the \pkg{GraphicxSP}
distribution. They are
\begin{itemize}
\item \texttt{grxsp\_tst\_noaeb.tex}: General test file demonstrating SP graphics,
    does not require AeB (Acro\negthinspace\TeX{} eDucation Bundle).
\item \texttt{grxsp\_tst\_aeb.tex}: Same as previous file, but using AeB.
