These files are +% embedded right in the \acronym{PDF} file, so they get transmitted +% along with it. The package also gives you control over the +% corresponding icon's properties and various other associated +% metadata. +% \end{abstract} +% +% \tableofcontents +% +% \section{Introduction} +% +% \acronym{PDF}, \adobe's Portable Document Format, is a common way to +% distribute documents that look the same on all platforms and output +% devices. Beginning with \acronym{PDF} version~1.3, \acronym{PDF} +% supports ``file attachment annotations''. These are arbitrary +% auxiliary files that get embedded directly into the \acronym{PDF} +% document, just like attachments in an e-mail message. +% +% The \pkgname{attachfile} package gives \pdflatex{} users the ability +% to add these attachments to their documents automatically. And +% because \latex{} is a markup language, not a \acronym{WYSIWYG} tool, +% the user has precise control over the location of the file attachment +% icons. If an icon representing an attached spreadsheet file is placed +% next to a figure, the icon will move along with the figure whenever +% the document is modified. Furthermore, it is possible to define +% global properties for all the file attachments in a document. With +% one command, a user can change the properties of all the icons in the +% entire document. +% +% Finally, one nifty feature that \pkgname{attachfile} supports is the +% ability to use your own icons, which can be text, graphics, tables, +% mathematics---you name it! With this feature, a \acronym{PDF} file +% can, for example, instruct the reader to click on a formula to extract +% the Mathematica\smallreg\ notebook that derived it. Or to click on a +% graph to extract the Microsoft\smallreg\ Excel spreadsheet that +% contains all the data that was plotted. The possiblities are endless. +% +% \bigskip +% +% Okay, let's get down to business. Here are some sample file +% attachments, so you can see if your \acronym{PDF} viewer is able to +% handle them: +% +% \begingroup +% \attachfilesetup{^^A +% color=1 0 0, +% mimetype=text/plain, +% author={Scott Pakin}, +% icon=PushPin, +% description={This document's BibTeX bibliography} +% } +% +% \begin{center} +% \begin{tabular}{@{}lc@{\qquad(Should look like this:~}c@{)}} +% Icon: & +% \attachfile{attachfile.bib} & +% \noattachfile \\ +% +% \latex\ text: & +% \textattachfile{attachfile.bib}{\texttt{attachfile.bib}} & +% \textcolor[rgb]{1,0,0}{\texttt{attachfile.bib}} +% \end{tabular} +% \end{center} +% \endgroup +% +% \noindent +% Each of the above points to the \bibtex\ bibliography (a plain text +% file) for the document you're reading now. Try extracting the +% attachment. In \adobeacrobat, this is achieved by right-clicking on +% the icon and choosing ``Extract File$\ldots$''. You can also +% double-click to open the file immediately. If you're unable to access +% the attached file, or you observe miscellaneous strange behavior, your +% \acronym{PDF} viewer might not be cabable of handling file attachments +% properly. See Section~\ref{sec:caveats} for some \acronym{PDF} viewer +% problems I encountered while testing \pkgname{attachfile}. +% +% +% \section{User interface} +% +% Load \pkgname{attachfile} by putting a |\usepackage{attachfile}| in +% your document's preamble. \pkgname{attachfile} implicitly loads a +% variety of other packages. Section~\ref{sec:caveats} presents the +% complete list. +% +% \pkgname{attachfile}~\fileversion{} does not have any of its own +% package options; any options that get passed to \pkgname{attachfile} +% are forwarded to \pkgname{hyperref}. Because \pkgname{hyperref} works +% best when loaded as one of the last packages in the document, the same +% holds true for \pkgname{attachfile}. +% +% \subsection{Commands} +% \label{sec:commands} +% +% The following are the commands that \pkgname{attachfile} makes +% available for attaching files, customizing the icon appearance, and +% changing various file attachment metadata. +% +% \begin{describemacro}{attachfile} +% \begin{decl} +% |\attachfile| \oarg{options} \marg{filename} +% \end{decl} +% \DescribeMacro{\attachfile} +% The |\attachfile| macro, has only one required argument: the name of +% the file to attach. |\attachfile| will insert an icon at the current +% point in the document to represent the attachment. \meta{options} is +% a list of optional parameters for describing the icon and other +% assorted metadata. It is described in Section~\ref{sec:options}. +% \end{describemacro} +% +% \begin{describemacro}{noattachfile} +% \begin{decl} +% |\noattachfile| \oarg{options} +% \end{decl} +% \DescribeMacro{\noattachfile} +% When writing instructions, it is sometimes convenient to describe what +% a file attachment icon looks like without actually attaching a file. +% That's what |\noattachfile| is for. All it does is insert the image +% of a file attachment icon into the document. \meta{options} is a list +% of optional parameters for describing the icon and other assorted +% metadata. It is described in Section~\ref{sec:options}. In +% particular, note that if the |print| option is set to |false| then +% |\noattachfile| will output empty space of the same size as the icon +% image. +% \end{describemacro} +% +% \begin{describemacro}{textattachfile} +% \begin{decl} +% |\textattachfile| \oarg{options} \marg{filename} \marg{text} +% \end{decl} +% \DescribeMacro{\textattachfile} +% |\textattachfile| is just like |\attachfile|, except that instead of +% using one of the predefined \acronym{PDF} icons, it lets you use an +% arbitrary piece of text to represent the attachment. The \meta{text} +% parameter is not limited to text; it can contain any arbitrary +% horizontal material. The following are all legal uses of +% |\textattachfile|: +% +% \begin{itemize} +% \item \texttt{You can} |\textattachfile{myfile.cc}{extract| \texttt{my +% source code}|}| \texttt{if your PDF viewer supports file annotations.} +% +% \item \texttt{It is intuitively obvious to even the most casual observer +% that} +% \begin{verbatim} +% \textattachfile{derivation.m}{$\displaystyle +% \frac{\partial E_p}{\partial w_{ji}^h} = +% -\sum_k (y_{pk} - o_{pk}) f_k^{o}{}'(\mbox{net}_{pk}^o) +% w_{kj}^o f_j^h{}'(\mbox{net}_{pj}^h) x_{pi}$} +% \end{verbatim} +% +% \item |\textattachfile{earningsdata.csv}{\includegraphics{earnings}}| +% +% \end{itemize} +% \end{describemacro} +% +% \begin{describemacro}{notextattachfile} +% \begin{decl} +% |\notextattachfile| \oarg{options} \marg{text} +% \end{decl} +% \DescribeMacro{\noattachfile} +% Just as |\noattachfile| is a dummy version of |\attachfile|, so +% |\notextattachfile| is a dummy version of |\textattachfile|. All +% |\notextattachfile| does is insert \meta{text} into the document +% according to \meta{options} (described in Section~\ref{sec:options}). +% In particular, note that if the |print| option is set to |false| then +% |\notextattachfile| will output empty space of the same size as +% \meta{text}. +% \end{describemacro} +% +% \begin{describemacro}{attachfilesetup} +% \begin{decl} +% |\attachfilesetup| \marg{options} +% \end{decl} +% \DescribeMacro{\attachfilesetup} +% If you find yourself passing the same set of options to multiple +% |\attachfile| calls in your document, you can use |\attachfilesetup| +% to specify default option values. |\attachfilesetup|'s \meta{options} +% parameter is the same as that used by |\attachfile| and is described +% in Section~\ref{sec:options}. Some noteworthy points are: +% +% \begin{enumerate} +% \item |\attachfilesetup| can be called as many times as desired. +% Any options specified replace the previous value of those options. +% All unspecified options are left alone. +% +% \item Options passed to |\attachfile| take precedence over those +% specified by |\attachfilesetup|. This lets you define default +% values for all file attachments and selectively override them on a +% per-attachment basis. +% +% \item Options set by |\attachfilesetup| are local to the current +% scope. This lets you assign defaults to a group of file attachments +% without affecting the global defaults. To define options that apply +% to the entire document, |\attachfilesetup| should be called at the +% top-level scope (which includes the document's prologue). +% \end{enumerate} +% \end{describemacro} +% +% \subsection{Options} +% \label{sec:options} +% +% \pkgname{attachfile} gives the user a great deal of control over the +% way files are attached to a document. All the commands in +% Section~\ref{sec:commands} accept the same set of options, which are +% entered as comma-separated, \meta{key}|=|\meta{value} pairs. Options +% can be specified in any order. Case is significant. And only the +% options you want to change need to be specified; the others will +% retain their previous value (or the default, if no previous value was +% specified). +% +% The following are the options \pkgname{attachfile} accepts, in +% alphabetical order. +% +% \begin{describeopt}{appearance} +% \begin{decl} +% |appearance=|\meta{boolean} +% \end{decl} +% The \pkgname{attachfile} package normally embeds the file attachment's +% icon explicitly with each file attachment annotation. (In +% \acronym{PDF}-speak, it includes an appearance dictionary in the +% \pdfname{FileAttachment} object.) The advantages to doing this are to +% ensure that: +% +% \begin{itemize} +% \item The file attachment icons look the same in all \acronym{PDF} +% viewers. +% +% \item \tex\ knows exactly how much space to allocate, instead of +% just guessing based on the size of the \adobeacrobat icons. +% +% \item Pre-1.3 \acronym{PDF} viewers don't regress to showing an +% ``unknown annotation type'' graphic. +% \end{itemize} +% +% \noindent +% However, the problems with embedding the icon graphic are: +% +% \begin{itemize} +% \item It adds a bit of extra bulk to the \acronym{PDF} file. +% +% \item It takes flexibility away from the \acronym{PDF} viewer, which +% can no longer choose for itself how best to render a file attachment +% icon. +% \end{itemize} +% +% The |appearance| option gives the author the ability to prevent the +% icon's appearance from being specified explicitly in the \acronym{PDF} +% file. By setting \texttt{appearance=false}, it will be left up to the +% \acronym{PDF} viewer to decide how to display the icon. +% \end{describeopt} +% +% \begin{describeopt}{author} +% \begin{decl} +% |author=|\meta{text} +% \end{decl} +% The metadata associated with a file attachment annotation includes the +% name of the person who attached the file. In \adobeacrobat, this +% information is shown when one right-clicks on the file attachment icon +% and selects \menuname{Properties}. By default, no author is listed, +% but specifying |author=|\meta{name} sets the author field to +% \meta{name}. +% \end{describeopt} +% +% \begin{describeopt}{color} +% \begin{decl} +% |color=|\meta{red} \meta{green} \meta{blue} +% \end{decl} +% The icons inserted by |\attachfile| and the text inserted by +% |\textattachfile| can be any color. The |color| option sets this +% color. Each of \meta{red}, \meta{green}, and \meta{blue} must be a +% decimal number between 0~(darkest) and 1~(brightest). The default is +% |color=1 0.9255 0.7765|, which is a beige. +% \end{describeopt} +% +% \begin{describeopt}{date} +% \begin{decl} +% |date=|\meta{text} +% \end{decl} +% Every annotation in a \acronym{PDF} can have a timestamp indicating +% when the annotation was last modified. \pkgname{attachfile} +% automatically adds a timestamp to file attachment annotations. It +% uses the time and date at which \latex\ started processing your job +% and converts it to the form ``|D:|\textit{YYYYMMDDHHmmSS}'', which is +% the format recommended by the \acronym{PDF} reference manual~\cite[p.\ +% 89]{PDFRef}, minus the Universal Time information.\footnote{In +% addition, seconds are hardwired to zero, because \tex's +% \texttt{\bslash time} command has only minute precision.} +% +% The |date| option lets you specify the modification date and time +% explicitly. Note, however, that although the \acronym{PDF} reference +% manual clearly states that ``viewer applications should be prepared to +% accept and display a string in any format''~\cite[p.\ 400]{PDFRef}, +% \adobeacrobat will ignore any timestamp that is not in the recommended +% format and will instead show the current date and time. +% \end{describeopt} +% +% \begin{describeopt}{description} +% \begin{decl} +% |description=|\meta{text} +% \end{decl} +% The metadata associated with a file attachment annotation can include +% a brief description of the file. In \adobeacrobat, this information +% is shown when one right-clicks on the file attachment icon and selects +% \menuname{Properties}. Also, in later versions of \adobeacrobat, the +% description field shows up as a tool~tip when the user mouses over the +% attachment. By default, no description is included, but specifying +% |description=|\meta{text} sets the description field to \meta{text}. +% \end{describeopt} +% +% \begin{describeopt}{subject} +% \begin{decl} +% |subject=|\meta{text} +% \end{decl} +% The metadata associated with a file attachment annotation can include +% a brief comment about the subject of the attachment. In +% \adobeacrobat, this information is shown when one right-clicks on the +% file attachment icon and selects \menuname{Properties}. By default, +% no subject is included, but specifying |subject=|\meta{text} sets the +% subject field to \meta{text}. +% \end{describeopt} +% +% \begin{describeopt}{icon} +% \begin{decl} +% |icon=|\meta{name} +% \end{decl} +% \acronym{PDF}~1.3 defines four icons that can be used for file +% attachments: \pdfname{Graph}, \pdfname{Paperclip}, \pdfname{PushPin}, +% and \pdfname{Tag}. These are shown in Table~\ref{tbl:icons}. If no +% icon name is specified, \pdfname{PushPin} is assumed. While the +% \acronym{PDF} specifications say that, normally, a \acronym{PDF} +% viewer chooses how to display each of those, the \pkgname{attachfile} +% package specifies the appearance explicitly. This is what +% \adobeacrobat does, presumably because doing so ensures that viewers +% which don't support file attachment annotations can still display +% something reasonable. The tradeoff is that it slightly increases the +% size of the \acronym{PDF} file. +% +% \begin{table}[tbp] +% \newcommand{\tallspace}{\rule[-2pt]{0pt}{24pt}} +% \centering +% \begin{tabular}{lc} +% \tallspace\pdfname{Graph} & \noattachfile[icon=Graph] \\ +% \tallspace\pdfname{Paperclip} & \noattachfile[icon=Paperclip] \\ +% \tallspace\pdfname{PushPin} & \noattachfile[icon=PushPin] \\ +% \tallspace\pdfname{Tag} & \noattachfile[icon=Tag] +% \end{tabular} +% \caption{Valid file attachment icons} +% \label{tbl:icons} +% \end{table} +% \end{describeopt} +% +% \begin{describeopt}{mimetype} +% \begin{decl} +% |mimetype=|\meta{type} +% \end{decl} +% It is considered good practice to specify the \acronym{MIME} +% type~\cite{Freed1996} of each attached file. That way, a +% \acronym{PDF} viewer can automatically launch an appropriate +% application to process the file. \meta{type} should be the form +% ``\meta{type}|/|\meta{subtype}''. For instance, a plain text file +% would be specified with ``\texttt{mimetype=text/plain}''. An +% \acronym{MPEG} movie would be specified with +% ``\texttt{mimetype=video/mpeg}''. The +% \href{http://www.iana.org/}{Internet Assigned Numbers Authority} +% maintains a list of registered media types~\cite{MediaTypes}, so look +% there first to see what type to use for a given file. +% \end{describeopt} +% +% \begin{describeopt}{print} +% \begin{decl} +% |print=|\meta{boolean} +% \end{decl} +% By default, file annotation icons print along with the rest of the +% document. By setting \texttt{print=false}, the icons will not print. +% Note that in \adobeacrobat, annotations will \emph{never} print unless +% the Annotations box is checked in the \Acrobatmenu{Print}{Print +% dialog}. +% \end{describeopt} +% +% \begin{describeopt}{timezone} +% \begin{decl} +% |timezone=|\meta{offset} +% \end{decl} +% Because \tex\ doesn't make the current timezone available, +% \pkgname{attachfile} is unable to include timezone information when it +% timestamps a file attachment. The |timezone| option lets you manually +% specify the timezone. \meta{offset} is the offset from +% Universal\index{Universal Time|usage} Time (a.k.a.\ \acronym{GMT}) and +% should be in the format specified in the \acronym{PDF} reference +% manual~\cite{PDFRef}, namely: +% +% \begin{center} +% \begin{tabular}{cp{0.66\textwidth}} +% |+|\meta{HH}|'|\meta{mm}|'| & +% \meta{HH} hours, \meta{mm} minutes later than Universal Time (i.e., +% east of Greenwich, England) \\[\baselineskip] +% +% |-|\meta{HH}|'|\meta{mm}|'| & +% \meta{HH} hours, \meta{mm} minutes earlier than Universal Time (i.e., +% west of Greenwich, England) \\[\baselineskip] +% +% |Z| & +% Universal Time (i.e., at the same longitude as Greenwich, England) +% \end{tabular} +% \end{center} +% +% \noindent +% For example, U.S. Central Time would be specified with |timezone=-06'00'|. +% \end{describeopt} +% +% \begin{describeopt}{zoom} +% \begin{decl} +% |zoom=|\meta{boolean} +% \end{decl} +% Normally, when a reader magnifies or reduces the view of the +% \acronym{PDF} document, the file annotation icons change size +% proportionally with the text. By setting \texttt{zoom=false}, the +% icon size does not scale. +% \end{describeopt} +% +% \bigskip +% The defaults for all of the options described above are summarized in +% Table~\ref{tbl:opt-defaults}. +% +% \begin{table}[htbp] +% \centering +% \edef\indexentry{options\levelchar default values\encapchar usage} +% \expandafter\index\expandafter{\indexentry} +% \begin{tabular}{@{}l@{\qquad}l@{}} \hline +% \multicolumn{1}{c}{Option\strut} & +% \multicolumn{1}{c}{Default setting} \\ \hline +% \indexedopt{appearance} & |true| \\ +% \indexedopt{author} & \emph{none} \\ +% \indexedopt{color} & |1 0.9255 0.7765| \\ +% \indexedopt{date} & \emph{automatic} \\ +% \indexedopt{description} & \emph{none} \\ +% \indexedopt{subject} & \emph{none} \\ +% \indexedopt{icon} & |PushPin| \\ +% \indexedopt{mimetype} & \emph{none} \\ +% \indexedopt{print} & |true| \\ +% \indexedopt{timezone} & \emph{none} \\ +% \indexedopt{zoom} & |true| \\ \hline +% \end{tabular} +% \caption{Default values for all options} +% \label{tbl:opt-defaults} +% \end{table} +% +% +% \section{Caveats} +% \label{sec:caveats} +% +% Note that there are a few caveats you should be aware of: +% +% \begin{enumerate} +% \item \pkgname{attachfile} will not run unless the following \latex\ +% packages are installed: \pkgname{calc}, \pkgname{keyval}, +% \pkgname{color}, \pkgname{hyperref}, and \pkgname{ifpdf}. +% +% \item File attachments are a \acronym{PDF}~1.3 feature. They will +% not be visible in \acronym{PDF} viewers that do support +% \acronym{PDF}~1.3. (Version~4.0 of \adobeacrobat is the first +% version of that program which does.) +% +% \item Even some viewers that purportedly support \acronym{PDF}~1.3 +% don't support file attachments. As far as I can tell, +% \adobeacrobatreader (the free, view-only version of \adobeacrobat) +% doesn't seem to support \emph{any} annotations except text +% annotations. +% +% \item Even some viewers that do support \acronym{PDF}~1.3 and file +% attachments don't support them under all circumstances. For +% instance, the Windows\smallreg\ version of \adobeacrobat, when +% functioning as a Web-browser plug-in, gives an error +% message\footnote{``Launching embedded files from within a browser +% environment is not allowed''.} when a file attachment icon is +% activated. +% +% \item Even in circumstances where file attachments are supported, +% the support may be flawed. For example, the Windows\smallreg\ +% version of \adobeacrobat changes a custom icon to the default icon +% when it's selected. +% \end{enumerate} +% +% \noindent +% In addition, \pkgname{attachfile} requires \pdflatex{} version~0.14 or +% later. While there are many other ways to produce \acronym{PDF} files +% from \latex{} source, \pkgname{attachfile}~\fileversion{} supports +% only \pdflatex, and only versions~0.14+. +% +% \bigskip +% +% Even given all of those caveats, file attachments can be a useful way +% to pass additional information along with a \acronym{PDF} file. The +% \pkgname{attachfile} package makes file annotations automatic and +% easy. +% +% +% \StopEventually{^^A +% \section{Future work} +% +% The following are some avenues for future work on +% \pkgname{attachfile}. First, \pkgname{attachfile} supports only +% \pdflatex\ for generating \acronym{PDF} files. It would be nice if it +% supported all the backends that \pkgname{hyperref} supports: +% dvipdfm\SortIndex{dvipdfm}{dvipdfm\encapchar usage}, +% dvips\SortIndex{dvips}{dvips\encapchar usage} with +% pdfmarks\SortIndex{pdfmarks}{pdfmarks\encapchar usage}, +% V\TeX\SortIndex{VTeX}{V\TeX\encapchar usage}, and so forth. Along +% those same lines, a ``draft'' package option would be a welcome +% addition, for use when \acronym{PDF} is not the final output format. +% +% Second, \acronym{PDF} supports platform-specific file attachments. +% That is, a file attachment icon can represent a different file when +% activated on Windows, Unix, or MacOS. It might be nice for +% \pkgname{attachfile} to support that feature. +% +% Finally, I'd like to see \pkgname{attachfile} expand sometime to +% support \emph{all} the various \acronym{PDF} annotations: +% \pdfname{Sound}, \pdfname{Movie}, \pdfname{Stamp}, \pdfname{Ink}, +% \pdfname{Popup}, etc. +% +% Of course, I make no promises that I'll ever do \emph{any} of the +% above. \pkgname{attachfile} was just something I wrote in my spare +% time, and it's unlikely I'll be able to devote another large block of +% time to enhance it. +% +% \begin{thebibliography}{1} +% \addcontentsline{toc}{section}{References} +% \bibitem{PDFRef} +% {Adobe Systems Incorporated}. +% \newblock {\em {PDF} Reference Version~1.6}. +% \newblock Adobe Press, fifth edition, December~3, 2004. +% \newblock ISBN~\mbox{0321304748}.

(Future versions of \pkgname{attachfile} may support +% dvipdfm\SortIndex{dvipdfm}{dvipdfm\encapchar usage}, +% dvips\SortIndex{dvips}{dvips\encapchar usage} with +% pdfmarks\SortIndex{pdfmarks}{pdfmarks\encapchar usage}, +% V\TeX\SortIndex{VTeX}{V\TeX\encapchar usage}, etc.) Also, \pdflatex\ +% must be in \acronym{PDF}-generating mode, not \acronym{DVI}-generating +% mode. So, to save the user some aggravation, we check for the correct +% backend right up front and give a warning if all is not well. Later, +% in Section~\ref{sec:dummy-commands}, we replace all of the core +% \pkgname{attachfile} macros with dummy versions so \latex\ can at +% least run to completion. +% \begin{macrocode} +\RequirePackage{ifpdf} +\ifpdf +\else + \PackageWarningNoLine{attachfile}{% + attachfile works _only_ with pdfLaTeX and _only_ in\MessageBreak + PDF-generating mode.
