+The richtext Package
+Author: D. P. Story
+Dated: 2016/10/03
+
+The richtext package is used to create rich text strings that can, in turn,
+be inserted into the RV (and V) keys of text field. Currently, only the eforms
+package supports the RV key.
+
+Now, I simply must get back to my retirement.

+\section{Introduction}
+
+Rich text contents for variable text (text fields and editable combo boxes)
+and markup annotations was introduced into the PDF specification beginning
+with PDF 1.5 (\app{Acrobat} and \app{Adobe Reader} version~6). The rich text
+strings are difficult to create for it requires reading from a number of
+sources. The \pkg{richtext} package provides commands and documentation
+needed to ``easily'' produce such rich strings. We demonstrate the results
+using the \pkg{eforms} package (the text field produced by \pkg{hyperref}
+does not support rich text).
+
+References for this material includes the \textsl{PDF
+Reference}~\cite{book:pdfspec}, the XFA specification~\cite{webpage:XFASpec},
+and the CSS2 specification~\cite{webpage:CSS2}. Additionally, the \textsl{JavaScript for
+Acrobat API Reference}~\cite{tech:AcroJS} covers the JavaScript API for
+handling rich text content.
+
+\section{Preamble: Required packages and options}
+
+The package has no options and only requires \pkg{xkeyval} and \pkg{ifxetex} packages.
+The package can produce rich text strings, but to actually use them, you'll need
+the \pkg{eforms} package.
+
+The package works for all drivers \app{dvips}, \app{pdflatex}, \app{xelatex},
+and \app{luatex}. The \pkg{eforms} package can automatically detect all
+drivers except \pkg{dvips}, and that is used by default.
+
+\section{Creating rich text strings}\label{s:CreateRTS}
+
+We begin by illustrating the result of the \pkg{richtext} package, consider the rich text field below.
+
+\rtpara[indent=first]{para1}{Now is the time for
+\span{style={bold,italic,strikeit},color=ff0000}{J\374rgen} and all
+good men to come to the aid of \it{their} \bf{country}. Now is the time for
+\span{style=italic}{all good} women to do the same.}
+\rtpara[indent=first]{para2}{With rich text, we can format the text within
+the text field. As a reader of this rich text field, you can edit the
+contents of the box, feel free to do so.}
+\rtpara[halign=right]{para3}{D. P. Story \span{url=http://www.acrotex.net}{AcroTeX.Net}}
+

+\end{center}
+
+To edit the field above, click in the field, press \uif{Ctrl+E} or \uif{Cmd+E} (for \app{Mac OS}) to obtain
+the \uif{Form Field Text Properties} toolbar. By pressing the \uif{More} button, you can see the additional
+properties of the field, as seen in \hyperref[fig:FPtabs]{Figure~\ref*{fig:FPtabs}}.
+
+
+A rich text may have any of several style attributes, many of these are illustrated in the above example.
+As a guide to introducing the attributes, we follow the \uif{Form Field Text Properties} dialog box shown
+in \hyperref[fig:FPtabs]{Figure~\ref*{fig:FPtabs}}.

+\caption{The Font, Paragraph and Link tabs}\label{fig:FPtabs}
+\end{figure}
+
+\newtopic\noindent
+The basic command for creating a rich text \emph{paragraph} is \cs{rtpara}:
+\bVerb\takeMeasure{\string\rtpara[\ameta{Para-Font-attrs}]\darg{\ameta{name}}\darg{\ameta{rich-text-paragraph}}}%
+\begin{dCmd}[commandchars=!()]{\bxSize}
+\rtpara[!ameta(Para-Font-attrs)]{!ameta(name)}{!ameta(rich-text-paragraph)}
+\end{dCmd}
+\eVerb where \ameta{Para-Font-attrs} are key-value pairs (in the {\LaTeX}
+sense) that are described in \hyperref[s:FLtabs]{Sections~\ref*{s:FLtabs}}
+and~\ref{s:Paratab}; these attributes are applied to the paragraph as a
+whole. The \ameta{name} is a unique name to be associated with
+\ameta{rich-text-paragraph} so it can be referenced later from within a text
+field. There are two types of attributes: \uif{Font} and \uif{Paragraph}, as
+guided by \hyperref[fig:FPtabs]{Figure~\ref*{fig:FPtabs}}. For convenience,
+the \uif{Link} attributes (URLs) are classified as \uif{Font}. The optional
+argument of \cs{rtpara} consists of usually \uif{Paragraph} attributes, most
+\uif{Font} attributes are also recognized.
+
+The definition of the first paragraph of the above rich text field reads as
+follows:
+\begin{Verbatim}[fontsize=\small]
+\rtpara[indent=first]{para1}{Now is the time for
+ \span{style={bold,italic,strikeit},color=ff0000}{J\374rgen}
+ and all good men to come to the aid of \it{their}
+ \bf{country}. Now is the time for \span{style=italic}
+ {all good} women to do the same.}
+\end{Verbatim}
+In this example, the optional argument for \cs{rtpara} was used to indent the
+paragraph. The rich text defined here is named \texttt{para1}. The third
+argument, \ameta{rich-text-string}, consists of ordinary text, the \cs{span}
+command used to insert special formatting for text, and certain other
+`short-cut' markups like \cs{it} and \cs{bf}. Note that the umluat (\"{u}) is
+expressed as octal (\cs{374}).
+
+The \cs{span} command is used to format individual sentence fragments. Its
+syntax is,
+\bVerb\takeMeasure{\string\span\darg{\ameta{Font-attrs}}\darg{\ameta{rich-text-string}}}%
+\begin{dCmd}[commandchars=!()]{\bxSize}
+\span[!ameta(Font-attrs)]{!ameta(rich-text-string)}
+\end{dCmd}
+\eVerb where \ameta{Font-attrs} are \uif{Font} attributes as described in
+\hyperref[s:FLtabs]{Sections~\ref*{s:FLtabs}}; these attributes are applied
+to the string \ameta{rich-text-string} only. The \cs{span} command, as
+described here, is only defined within the third argument
+(\ameta{rich-text-paragraph}) of \cs{rtpara}. This is necessary because
+\cs{span} is a {\TeX} primitive command, and we must not overwrite its
+definition.
+
+When you create a \emph{rich text string} there is a parallel development of a
+\emph{plain text string}, the string without its rich text markup, these two
+(rich and plain strings) are used to populate the values of the \psf{RV} and
+\psf{V} keys of a text field. When you define a rich text paragraph string
+under its own \ameta{name}, you can typeset it (to check the syntax) and its
+plain text counterpart using the \cs{useRV\darg{\ameta{name}}} and
+\cs{useV\darg{\ameta{name}}} commands. For example,
+\begin{quote}\raggedright\ttfamily\makeatletter\def\rt@SC{;\penalty0}%
+\rtpara[indent=first]{para1}{Now is the time for
+\span{style={bold,italic,strikeit},color=ff0000}{J\string\374rgen} and all
+good men to come to the aid of \it{their} \bf{country}. Now is the time for
+\span{style=italic}{all good} women to do the same.}
+\makeatother
+\hspace*{-\leftmargini}\textbf{\cs{useRV\darg{para1}:}}\ \useRV{para1}\\[\baselineskip]
+\hspace*{-\leftmargini}\textbf{\cs{useV\darg{para1}:}}\ \useV{para1}
+\end{quote}
+These commands may also be used to insert the strings into the \psf{RV} and
+\psf{V} keys, respectively; though the \pkg{richtext} package offers an
+alternative technique.
+
+\subsection{The \texorpdfstring{\uif{Font}}{Font} and
+\texorpdfstring{\uif{Link}}{Link} tabs}\label{s:FLtabs}
+
+In this section, we cover the \uif{Font} and \uif{Link} tabs, as well as other attributes
+not listed on any tab.
+
+\subsubsection{The \texorpdfstring{\uif{Font}}{Font} tab}
+
+We discuss the \uif{Font} tab of \hyperref[fig:FPtabs]{Figure~\ref*{fig:FPtabs}}. The
+key-value for each of the attributes is given and described briefly. These key-values
+may appear as \ameta{Font-attrs} or \ameta{Para-Font-attrs}.
+\begin{description}
+%The font family used to draw the text. It is an array of family names to be searched for in order. The first
+%entry in the array is the font name of the font to use. The second entry is an optional generic family name
+%to use if an exact match of the first font is not found. The generic family names are
+%symbol, serif, sans-serif, cursive, monospace, fantasy
+%The default generic family name is sans-serif.
+\item[\uif{Font:}] \texttt{font=\ameta{font\_name}} A font name or a list of
+ font names to be used to display the enclosed text. The first
+ entry is the font name of the font to use. The second font name is
+ typically a generic family name to use if an exact match is not found.
+ The generic family names are \texttt{symbol}, \texttt{serif},
+ \texttt{sans-serif}, \texttt{cursive}, \texttt{monospace}, and
+ \texttt{fantasy}. The default is \texttt{sans-serif}. If a typeface name
+ contains white space, enclose it within single quotes (\texttt{'}).

+In the second example, only `Myriad Pro' is actually set in the Myriad Pro font; the rest of the sentence
+is typeset in the default font, Helvetica in this case. Use \uif{Ctrl+E} (\uif{Cmd+E}) to inspect the properties
+of these two fields and verify the fonts are Arial, Myriad Pro, and Helvetica.
+
+\item[\uif{Size}:] \texttt{size=\ameta{dec\_num}} The size of the font to
+ be used. The value of \texttt{size} is \ameta{dec\_num}, a (positive)
+ decimal number.
+\begin{flushleft}\small %\previewtrue

+\item[\uif{Baseline Shift:}] \texttt{raise=\ameta{def\_num}} The position of the baseline of the text is determined

+it \texttt{4pt}.
+\begin{flushleft}\small

+\end{flushleft}
+
+\item[\uif{Underline:}]
+ \texttt{ulstyle=\ameta{\upshape{none|ul|2ul|wul|2wul}}} The
+ \texttt{ulstyle} key determines the style of underlining, possible values
+ are \texttt{none} (no underlining), \texttt{ul} (underlining),
+ \texttt{2ul} (double-line underlining), \texttt{wul} (word underlining),
+ and \texttt{2wul} (double-line word underlining).

+
+\item[\uif{Style}:]
+ \texttt{style=\darg{\upshape{[bold,][italic,][strikeit]}}} Unlike some
+ of the other (choice) keys, the value of the \texttt{style} key is any
+ \emph{subset} of the values listed: for example, \texttt{style=bold}
+ paints the underlying text in bold, \texttt{style=\darg{bold,italic}}
+ yields bold-italic font, and, for a final example,
+ \texttt{style=\darg{italic,strikeit}} typesets its text in
+ strike-through italic. Multiple values must be enclosed in braces
+ (\darg{}) so that \pkg{xkeyval} can correctly parse them.

+
+\item[\uif{Color:}]
+ \texttt{color=\ameta{\upshape{\meta{rrggbb}|\darg{rgb(\meta{rrr,ggg,bbb})}}}}
+ Use this key to color the effected text. There are two
+ methods of defining color:
+\begin{itemize}
+ \item[(1)] \meta{rrggbb} uses a 2-digit hexadecimal
+ value for each component;
+ \item[(2)] \texttt{rgb(\meta{rrr,ggg,bbb})} uses a decimal
+ value (0--255) for each component.
+\end{itemize}
+ Because the second form contains
+ commas, it must necessarily be enclosed in braces (\darg{}) to be
+ correctly parsed by \pkg{xkeyval}.
+\begin{flushleft}\small %\previewtrue
+\verb|\rtpara{para1}{This is \span{color={rgb(255,0,0)}}{red} and|
+\hspace*{20pt}\verb|this is \span{color=0000ff}{blue}.|

+Things are not as bad as it seems. The \pkg{xcolor} package has the

+\paragraph[Bold and italic]{Bold and italic.}\chgCurrLblName{Bold and italic}\label{para:BandI}
+There are a couple of XHTML
+elements that can also be used for bold and italic.
+\begin{itemize}
+ \item \cs{bf\darg{\ameta{text}}} expands to \texttt{<b>\ameta{text}</b>} and places
+ \ameta{text} in bold font. May be used within a \cs{span} command.
+ \item \cs{it\darg{\ameta{text}}} expands to \texttt{<i>\ameta{text}</i>} and places
+ \ameta{text} in italic font. May be used within a \cs{span} command.
+\end{itemize}
+Both \cs{bf} and \cs{it} are local commands, undefined outside of the third argument
+of \cs{rtpara}. Do not code \texttt{<b>\ameta{text}</b>} or \texttt{<i>\ameta{text}</i>}

+\begin{itemize}

+There is another key, the \texttt{raw} key, that can be used

+The syntax for a CSS2 attribute is `\texttt{\ameta{key}:\ameta{value};}', that is, keys and values are separated

+
+It appears that tab stops work as well, these can be specified using the \texttt{raw} key as well. Refer to the

+\paragraph[Special characters]{Special characters.}\chgCurrLblName{Special characters}\label{para:SpecChars}

+number of changes in \cs{catcode}s and redefinitions occur. Within
+\cs{rtpara}, the following characters \emph{do not need to be} escaped:
+\texttt{\$}, \texttt{\#}, and \texttt{\string~} (tilde). The following
+characters \emph{need to be} escaped: \texttt{\cs{<}}, \texttt{\cs{>}},
+\verb|\&|, \verb|\%| (the comment character (\texttt{\%}) retains its
+{\LaTeX} meaning), \verb|\{|, and \verb|\}| (the left and right braces have
+their usual \TeX/LaTeX{} meaning). The single quote (\texttt{'}) and double quote (\texttt{"}) may
+be optionally escaped (to \cs{'} and \cs{"}). Escape them if something goes wrong. Use the
+command \cs{cs\darg{\ameta{text}}} to obtain a literal backslash (`\verb|\|'); for example
+\verb|\cs{LaTeX}|, shown below, expands to `\texttt{\cs{LaTeX}}'.

+\section{Rich text fields}
+
+Up to this point in the manual, the discussion has focused on creating rich
+text strings. They may be fun to create and look at, but usually we want to
+insert them into a text field. The comments here are for \pkg{eforms}
+package, having checked with \pkg{hyperref} to see if there is a \psf{RV}
+key, there is not.
+
+To create a rich text field, use the \cs{textField} command of \pkg{eforms}:
+\begin{Verbatim}[xleftmargin=\amtIndent,commandchars=!()]
+\textField[\Ff{\FfRichText}\Ff{\FfMultiline}
+ \DS{!ameta(defaultstyle)}\RV{!ameta(rich-value)}\V{!ameta(value)}
+]{!ameta(fld-name)}{!ameta(width)}{!ameta(height)}
+\end{Verbatim}
+Remove \cs{Ff\darg{\cs{FfMultiline}}} if the field is only a single line. We
+discuss the \psf{DS} key (\cs{DS}) key first, followed by the keys \psf{RV}
+and \psf{V} (\cs{RV} and \cs{V}).
+
+\subsection{The \texorpdfstring{\protect\psf{DS}}{DS} key}
+
+The value of the \psf{DS} key sets the formatting for the text field as a
+whole. Most importantly, use it to set the font, text size, and color.
+There is a built-in default style, defined below:
+\bVerb\takeMeasure{\small\string\newcommand\string\useDefaultDS\darg{font-family:Helvetica,sans-serif;}}%
+\begin{dCmd}[fontsize=\small,commandchars=!()]{\bxSize}
+\newcommand\useDefaultDS{font-family:Helvetica,sans-serif;
+ font-size:12.0pt;font-style:normal;font-weight:normal;
+ text-align:left;color:#000000}
+\end{dCmd}
+\eVerb You may redefine it to suit your purposes, but this is what
+\app{Acrobat}/\app{Adobe Reader} sets as the default style. I would recommend
+\cs{setDefaultStyle} to define your own custom default style. \cs{useDefaultDS} is the reason
+why most all rich text fields in this document use Helvetica at \texttt{12pt}! Use
+\cs{useDefaultDS} as follows, shown in bold font:
+\begin{Verbatim}[xleftmargin=\amtIndent,commandchars=!()]
+\textField[\Ff{\FfRichText}\Ff{\FfMultiline}
+ \DS{!textbf(\useDefaultDS)}\RV{!ameta(rich-value)}\V{!ameta(value)}
+]{!ameta(fld-name)}{!ameta(width)}{!ameta(height)}
+\end{Verbatim}
+
+\newtopic\noindent To create a custom default style use \cs{setDefaultStyle}.
+\bVerb\takeMeasure{\string\setDefaultStyle\darg{\ameta{name}}\darg{\ameta{Font-Para-attrs}}}%
+\begin{dCmd}[commandchars=!()]{\bxSize}
+\setDefaultStyle{!ameta(name)}{!ameta(Font-Para-attrs)}
+\useDS{!ameta(name)}
+\end{dCmd}
+Typically, the key-values associated with the \uif{Font} tab, Section~\ref{s:FLtabs}, may be used,
+some key-values are removed, such as \texttt{ul}, \texttt{raise}, and \texttt{url}. When you've defined
+a custom default style using \cs{setDefaultStyle}, insert \cs{useDS\darg{\ameta{name}}} as the value
+of the \psf{DS} key.\incFldCnt
+\begin{Verbatim}[xleftmargin=\amtIndent,fontsize=\small,commandchars=!()]

+These are discussed in the next section.
+
+\subsection{The \texorpdfstring{\protect\psf{RV}}{RV} and
+\texorpdfstring{\protect\psf{V}}{V} keys}
+
+The techniques to handle multiple paragraph fields are more complex (but not discouragingly so),
+that topic will be taken up after the discussion of single paragraph fields.
+
+\subsubsection{Single paragraph fields}
+
+For a single paragraph field, there is only one \cs{repara} defined prior to the field. This string
+data (both rich and plain) are inserted into the \cs{RV} and \cs{V} keys using \cs{useRV} and \cs{useV}. We repeat the
+previous example, but with the emphasis on \cs{RV} and \cs{V}, and not on \cs{DS}.
+\begin{Verbatim}[xleftmargin=\amtIndent,fontsize=\small,commandchars=!()]
+\rtpara{para1}{The font should be \'Myriad Pro\' at 10pt
+ and the default color of the field is webbrown, a
+ color defined in the web package.}
+\setDefaultStyle{myStyle}{font='Myriad Pro',size=10,
+ color=!htmlWebBrown}
+\textField[\Ff{\FfRichText}\Ff{\FfMultiline}
+ \DS{\useDS{myStyle}}\RV{!textbf(\useRV{para1})}\V{!textbf(\useV{para1})}
+]{rtFld!the!fldCnt}{3in}{16bp*3}
+\end{Verbatim}
+\begin{quote}
+\rtpara{para1}{The font should be \'Myriad Pro\' at 10pt and the
+default color of the field is webbrown, a color defined in the web package.}
+\setDefaultStyle{myStyle}{font='Myriad Pro',size=10,color=\htmlWebBrown}
+\textField[\Ff{\FfRichText}\Ff{\FfMultiline}
+\DS{\useDS{myStyle}}\RV{\useRV{para1}}\V{\useV{para1}}]{rtFld\the\fldCnt}{3in}{16bp*3}
+\end{quote}
+We declare our rich paragraph string using \cs{rtpara} and name it
+\texttt{para1}. We insert two data streams, one into the rich text key
+(\cs{RV\darg{useRV\darg{para}}}) and the other into the (plain) text key
+(\cs{V\darg{useV\darg{para}}}).
+
+
+\subsubsection{Multiple paragraph fields}
+
+The strategy is to use several \cs{rtpara} commands to declare several rich
+text paragraph. What is the best way to `paste' these paragraphs together? The method
+developed is to use \cs{setRVVContent} command.
+\bVerb\takeMeasure{\string\setRVVContent\darg{\ameta{name}}\darg{ \darg{\ameta{name\SUB{1}}}\darg{\ameta{name\SUB{2}}}...\darg{\ameta{name\SUB{k}}} }}%
+\begin{dCmd}[commandchars=!()]{\bxSize}
+\setRVVContent{!ameta(name)}{ {!ameta(name!SUB(1))}{!ameta(name!SUB(2))}...{!ameta(name!SUB(k))} }
+\end{dCmd}
+\eVerb where \ameta{name\SUB{i}} is the name of a rich text paragraph string,
+or is the keyword \texttt{skipline}. The keyword \texttt{skipline} is
+case-sensitive, it must be typed exactly. The role \texttt{skipline} plays is to
+insert a blank line between paragraphs; \texttt{\darg{skipline}} inserts one
+blank line between paragraphs.
+
+Having composed how the strings are to be put together, we need to insert them into
+\psf{RV} and \psf{V}.
+\bVerb\takeMeasure{\string\useRVContent\darg{\ameta{name}}}%
+\begin{dCmd}[commandchars=!()]{\bxSize}
+\useRVContent{!ameta(name)}
+\useVContent{!ameta(name)}
+\end{dCmd}
+\eVerb where \ameta{name} is the name given in a previous \cs{setRVVContent}
+command. Insert \cs{useRVContent} as the value of the \psf{RV} key, and
+\cs{useVContent} as the value of the \psf{V} key.
+
+We take as an example, the one from Section~\ref{s:CreateRTS}.\incFldCnt
+\begin{Verbatim}[fontsize=\small]
+\rtpara[indent=first]{para1}{Now is the time for
+ \span{style={bold,italic,strikeit},color=ff0000}{J\374rgen}
+ and all good men to come to the aid of \it{their}
+ \bf{country}. Now is the time for \span{style=italic}
+ {all good} women to do the same.}
+\rtpara[indent=first]{para2}{With rich text, we can format the
+ text within the text field. As a reader of this rich text
+ field, you can edit the contents of the box, feel free to
+ do so.}
+\rtpara[halign=right]{para3}{D. P. Story
+ \span{url=http://www.acrotex.net}{AcroTeX.Net}}
+\end{Verbatim}
+Now set the content with \cs{setRVVContent}, naming it \texttt{myContent}.
+\begin{Verbatim}[fontsize=\small]
+\setRVVContent{myContent}{{para1}{para2}{skipline}{para3}}
+\end{Verbatim}
+Having done all that, we create our rich text field:
+\begin{Verbatim}[fontsize=\small,commandchars=!()]
+\begin{center}
+\textField[\Ff{\FfRichText}\Ff{\FfMultiline}
+ \DS{\useDefaultDS}
+ !textbf(\RV{\useRVContent{myContent}})
+ !textbf(\V{\useVContent{myContent}})
+]{rtFld!the!fldCnt}{4in}{10\baselineskip}
+\end{center}
+\end{Verbatim}
+where, the \cs{RV} and \cs{V} keys are highlighted in bold for your viewing pleasure.
+The rich text field the result of these declarations.
+
+\rtpara[indent=first]{para1}{Now is the time for
+\span{style={bold,italic,strikeit},color=ff0000}{J\374rgen} and
+all good men to come to the aid of \it{their} \bf{country}. Now
+is the time for \span{style=italic}{all good} women to do the same.}
+\rtpara[indent=first]{para2}{With rich text, we can format the text within
+the text field. As a reader of this rich text field, you can edit the
+contents of the box, feel free to do so.}
+\rtpara[halign=right]{para3}{D. P. Story \span{url=http://www.acrotex.net}{AcroTeX.Net}}
+
+\setRVVContent{myContent}{{para1}{para2}{skipline}{para3}}
+
+\begin{center}
+%\previewtrue
+\incFldCnt
+\textField[\Ff{\FfRichText}\Ff{\FfMultiline}
+\DS{\useDefaultDS}%\DS{\useDS{myDS}}%
+\RV{\useRVContent{myContent}}\V{\useVContent{myContent}}]{rtFld\the\fldCnt}{4in}{10\baselineskip}
+\end{center}
+
+The argument of \cs{setRVVContent} is pretty robust. In making our declarations, we can type:
+\begin{Verbatim}[xleftmargin=\amtIndent,fontsize=\small]
+\setRVVContent{myContent}
+{
+ {para1}
+ {para2}
+ {skipline}
+ {skipline}
+ {para3}
+}
+\end{Verbatim}
+Note that I've added a \texttt{skipline} so that are two blank lines after the second paragraph
+and before the third paragraph.

+% \section{Introduction}
+% This package supports the creation of \emph{rich text strings} (a type of pdf string). A
+% rich text string is used in a rich text field as the value of the PDF key \psf{RV}. We also support
+% the \psf{DS} key which determines the default style.
+%
+% From the PDF Reference (PDF~1.7), page 1310, ``these rich text strings are fully-formed XML documents that conform to the rich
+% text conventions specified for the XML Forms Architecture (XFA) specification,
+% which is itself a subset of the XHTML 1.0 specification, augmented with a
+% restricted set of CSS2 style attributes.''
+%
+% A rich text field may be created using the \pkg{eforms} package, like so
+%\begin{verbatim}
+% \textField[\Ff{\FfRichText}\Ff{\FfMultiline}<other-options>
+% \DS{<defaultstyle>}\RV{<richvalue>}\V{<value>}
+% ]{<fldname>}{<width>}{<height>}
+%\end{verbatim}
+% This package provides commands and methods for `conveniently' create values
+% \texttt{<richvalue>} and \texttt{<defaultstyle>} for \psf{RV} and
+% \psf{DS}; additionally, the value \texttt{<value>} of the \psf{V} key is the `plain' text
+% value of the field; that is the text with all the formatting stripped out.

+% \subsection{The \texorpdfstring{\protect\uif{Font}}{Font}
+% and \texorpdfstring{\protect\uif{Link}}{Link} tabs}
+% We support the attributes seen in the above list. We further
+% support subscripts, superscript, and links in this section.
+% \begin{macrocode}
+\newif\ifrtfontstyle\rtfontstylefalse
+% \end{macrocode}
+% The keys of the \texttt{rtFont} key-value family. Supported keys are \texttt{font}, \texttt{size}, \texttt{raise}, \texttt{ulstyle},
+% \texttt{color}, \texttt{url}, and \texttt{style}. Superscripts and subscripts are handled differently.
+% \begin{macrocode}
+% \end{macrocode}
+% The \IndexKey{font}\texttt{font} key's value is a font name, if the name contains a space, it should be enclosed
+% in single quotes: \texttt{font=Arial} or \texttt{font='Myriad Pro'}.
+% \begin{macrocode}
+\define@key{rtFont}{font}[]{\def\rt@argi{#1}\ifx\rt@argi\@empty
+ \let\rf@font\@empty\else\rtfontstyletrue
+ \def\rf@font{font-family:#1}\fi}
+% \end{macrocode}
+% The value of \IndexKey{size}\texttt{size} is the size of the font, as measured in points
+% \texttt{font=12pt}, note the use of the entity `\texttt{pt}'.
+% \begin{macrocode}
+\define@key{rtFont}{size}[]{\def\rt@argi{#1}\ifx\rt@argi\@empty
+ \let\rf@size\@empty\else\rtfontstyletrue\def\rf@size@num{#1}%
+ \def\rf@size@pt{#1pt}\def\rf@size{font-size:#1pt}\fi}
+\def\rf@size@num{12}\def\rf@size@pt{12pt}
+% \end{macrocode}
+% The key \IndexOpt{raise}\texttt{raise} corresponds to the user interface item \uif{Baseline Shift},
+% measured in points, for example, \texttt{raise=6pt}.
+% \begin{macrocode}
+\define@key{rtFont}{raise}[]{\def\rt@argi{#1}\ifx\rt@argi\@empty
+ \let\rf@raise\@empty\else\rtfontstyletrue
+ \def\rf@raise{vertical-align:#1pt}\fi}
+% \end{macrocode}
+% The key \IndexOpt{ulstyle}\texttt{ulstyle} supplies an underline attribute, for example,
+% \texttt{ul=word} underlines each word in the span.
+% \begin{macrocode}
+\define@choicekey+{rtFont}{ulstyle}[\val\nr]%
+ {none,ul,2ul,wul,2wul}[none]{%
+ \ifcase\nr\relax
+ \def\rf@ul{none}\or
+ \def\rf@ul{underline}\or
+ \def\rf@ul{double}\or
+ \def\rf@ul{word}\or
+ \def\rf@ul{double word}\fi
+ \rtfontstyletrue
+}{}
+% \end{macrocode}
+% The key \IndexOpt{color}\texttt{color} supplies a color attribute for the text in the span.
+% There are two formats: \texttt{rrggbb} (hex) and \texttt{rgb(r,g,b)} (0-255). For example,
+% \texttt{color=ff0000} or \texttt{color=rgb(255,0,0)} both color the text red.
+% \begin{macrocode}
+\def\rt@r{r}\let\rt@One=1 \let\rt@Zero=0
+\def\rt@parseColor#1(#2\@nil{\def\rt@argi{#2}\ifx\rt@argi\@empty
