The elements include the positioning of text on a page, the disposition of floats on a page, the geometrical layout of lists and footnotes, the design of section headers and their display in a table of contents. It also enables document designers to experiment with potential layout designs. \end{abstract} \tableofcontents \listoftables \listoffigures \clearpage \pagenumbering{arabic} \section{Introduction} \LaTeX{} has several pre-defined styles for the layout of typeset documents~\cite{LAMPORT94}. Authors using \LaTeX{} sometimes wish to understand how these layouts are parameterised (or controlled). The \texttt{layouts} package enables the display of certain of these parameterised layouts, showing what the parameters control. It also provides facilities for experimenting with different values of the typesetting parameters, showing the results graphically. The \file{layouts} package was developed as an aid to the author when he was developing a new \LaTeX{} class for typsetting ISO standards. The development of the package has benefitted from Kent McPherson's \pixfile{layout.sty}~\cite{MCPHERSON88}. \subsection{Command types} The majority of the commands provided fall into one of several categories. \begin{description} \item[Drawing] Commands of the form \pcom{draw}\textit{L}, \pcom{}\textit{L}\texttt{diagram}, and \pcom{}\textit{L}\texttt{design} generate a \LaTeX{} \texttt{picture} of the layout \textit{L}. \item[Current layout] Commands of the form \pcom{current}\textit{L} collect, as far as possible, the values of the layout parameters for the current \textit{L} layout environment for use by the corresponding \pcom{draw}\textit{L} command. If a parameter value is not directly accessible, then a typical value is provided. \item[Layout values] Commands of the form \pcom{}\textit{L}\texttt{values} produce a tabular listing of the current values of the parameters controlling the layout \textit{L}. As far as possible these are the actual values. In some cases the values are hard-wired in the body of a macro, and in these cases reasonable guesstimates are made of a `typical' value. In the printed table, guesstimates are indicated by appending two question marks (??) to the printed value. Note that the tabular listing produced by a \pcom{}\textit{L}\texttt{values} command is not the same as a listing that might be produced by the corresponding \pcom{draw}\textit{L} command. The appearance of the table may be controlled as follows. \begin{itemize} \item The declaration \pixcom{printheadingstrue} will cause a short title to be placed above the tabular; the tabular is untitled when \pixcom{printheadingsfalse} is in effect. \item The font size used for the table is specified via the \pixcom{setvaluestextsize}\marg{fontsize} macro, where \meta{fontsize} is one of LaTeX's font size commands (e.g., \pixcom{footnotesize}, which is the default value.). \end{itemize} \item[User-specified parameter values] Commands of the form \pcom{try}\textit{P} can be used to change the value of the layout parameter \textit{P}. Note that these commands do \emph{not} affect the the layout of the document, they only modify the values used in displaying a layout. \item[Control] Commands of the form \verb|\|\textit{C}\texttt{true} or \verb|\|\textit{C}\texttt{false} control certain aspects of the kinds of layouts pictured. \end{description} \subsection{General facilities} In order to initialize the \file{layouts} package correctly for your document, the command \pixcom{setuplayouts} must be issued immediately after the \verb|\begin{document}|, or at least before any following command that changes font sizes or suchlike. Fortunately you don't have to concern youself with this as it is called automatically by the \file{layouts} package. However, you may call it yourself at some later point in the document to pick up the current value of the \pixcom{baselineskip} or \pixcom{parskip} if these have been modified. The \pixcom{setuplayouts} command also sets the \pixcom{setlayoutscale} to its default value of $0.5$. \subsubsection{Scaling} A few layout pictures are drawn full size. Most are drawn less than full size, typically to half-scale. To make the pictures fit your document neatly, you may wish to change the scale. The command \verb|\setlayoutscale{|\meta{frac}\verb|}|,\ixcom{setlayoutscale} where \meta{frac} is a decimal number (e.g., $0.75$) sets the scaling. For example, \verb|\setlayoutscale{0.5}| will produce pictures at half full size, and \verb|\setlayoutscale{1.0}| will make the pictures full size. \subsubsection{Layout types} In general, two kinds of layout pictures can be produced. \begin{enumerate} \item A picture showing a generic layout and its controlling parameters is produced by a command of the form \pcom{}\textit{L}\texttt{diagram}. The same effect may be achieved by using a \pcom{draw}\textit{L} after the declaration \pixcom{drawparameterstrue}. \item A picture showing an `actual' layout is produced by a command of the form \pcom{}\textit{L}\texttt{design}. The same effect may be achieved by using a \pcom{draw}\textit{L} after the declaration \\ \pixcom{drawparametersfalse}. \begin{quote} \textbf{Warning:} If an actual layout differs too much from a `normal' layout then LaTeX may hiccup a time or two. The typical problem is when a dimension that is expected to be positive is actually negative; LaTeX will respond with an error message like `Bad \pcom{line} or \pcom{vector} argument'. \end{quote} \end{enumerate} \begin{quote} \textbf{Note:} The \pcom{}\textit{L}\texttt{diagram} and \pcom{}\textit{L}\texttt{design} commands were introduced in version 2.5 of the package. The previous method of generating pictures (via \pcom{draw}\textit{L} and \verb?\drawparameters...?) is mainly retained for compatibility reasons. \end{quote} Examples of both kinds of layout are shown later. Some aspects of the appearance of the pictures can be controlled. The following apply to both generic and actual layouts. \begin{itemize} \item The size of the font used for displaying the parameters is specified via the command: \\ \pixcom{setparameterstextsize}\marg{size}, where \meta{size} is one of LaTeX's font size commands. \\ The initial setting is \verb|\setparameterstextsize{\footnotesize}|. \item Some parts of the layouts are labelled, for example the footer area in the page layout is labelled `footer'. The macro \pixcom{setlabelfont}\marg{font} can be used to control the font used for typesetting these labels. The default is \verb|\setlabelfont{\normalsize}|, but can be, for example, \verb|\setlabelfont{\large\itshape}| to use a large italic font instead. Note that \meta{font} must be specified as a declaration(s). \end{itemize} The following controls only apply to actual layouts (i.e., when using \pcom{}\textit{L}\texttt{design}, or the earlier \pixcom{drawparametersfalse} \pcom{draw}\textit{L} pairing is in effect). \begin{itemize} \item Some layouts have some explanatory header text. Putting \pixcom{printheadingsfalse} prohibits these while \pixcom{printheadingstrue} lets them be printed. \item In the generic layouts, the lengths controlled by the various parameters are indicated by dimension lines; these are not normally shown in actual layouts. Using \pixcom{drawdimensionstrue} will let these be shown in actual layouts. The default setting is \pixcom{drawdimensionsfalse}. \begin{quote} \textbf{Warning:} If you draw actual layouts with \pixcom{drawdimensionstrue} the drawings may be overburdened and if the layout differs too much from a `normal' layout then LaTeX may hiccup a time or two (typically with an error message like `Bad \pcom{line} or \pcom{vector} argument'). \end{quote} \item When \pixcom{printparameterstrue} is in effect, a table of the parameter values will be printed below the layout. Unsurprisingly, \pixcom{printparametersfalse} prohibits the table. The default is \pixcom{printparameterstrue}. \end{itemize} \subsubsection{Length units} The tabular listings of the parameter length values produced by the \pcom{}\textit{L}\texttt{values} macros give the lengths in TeX points by default. The length units may be set by the \pixcom{printinunitsof}\marg{unit} command. The \meta{unit} argument may be any of TeX's length units, except for scaled point. That is, the allowable values are \texttt{pt}, \texttt{pc}, \texttt{in}, \texttt{mm}, \texttt{cm}, \texttt{bp}, \texttt{dd}, or \texttt{cc}; an unkown unit is treated as though it were \texttt{pt}. When printing in pt units any stretch or shrink values are printed as well; using \texttt{PT} instead of \texttt{pt} eliminates these `rubber' values. The initial setting is \verb|\printinunitsof{pt}|. The macro \pixcom{prntlen}\marg{length} prints the value of \meta{length}, where \meta{length} is a LaTeX length, using the units specified by \pixcom{printinunitsof}. For example, the following code \begin{verbatim} The textwidth is \printinunitsof{pt}\prntlen{\textwidth} which is also \printinunitsof{in}\prntlen{\textwidth} or \printinunitsof{mm}\prntlen{\textwidth}. \end{verbatim} prints out: \\ \begingroup The textwidth is \printinunitsof{pt}\prntlen{\textwidth} which is also \printinunitsof{in}\prntlen{\textwidth} or \printinunitsof{mm}\prntlen{\textwidth}. \endgroup \subsection{Usage} The drawing commands (i.e., \verb|\...diagram|, \verb|\...design| and \verb|\draw...|) are typically used within a \pixenv{figure} environment, although they can be used in running text. Internally they generate a \pixenv{picture} and \pixenv{tabular} environment, both enclosed in their own \pixenv{center} environments. The \pixcom{setlayoutscale} command can be used anywhere in a document after the initial \pixcom{setuplayouts} command. Used in running text it will alter the scale factor for all succeeding drawing commands. However, if \pixcom{setlayoutscale} is called within an environment, such as the \pixenv{figure} environment, it will only affect the scale factors for succeeding drawing commands in that environment. The \file{layouts} package uses many \LaTeX{} counters and lengths. If it is used with too many other packages, the available number of counters and lengths may be exhausted. Essentially, the \file{layouts} package is intended to be used in short documents as an exploratory tool when designing the typesetting rules to be embodied in a new package or class file. \section{Page spread} \suppressfloats[t] Book designers often start by determining the proportions of a page, the proportions of the text block, and the position of the text block on the page. Often the width of a page is taken as the starting point. In the following let $w$ be the width of a single page; that is, the distance from the spine to the outside of the fore edge. I also use the other symbols given in \tref{tab:spread}. \begin{table} \centering \caption{Page spread symbols} \label{tab:spread} \begin{tabular}{|c|l|} \hline Symbol & Meaning \\ \hline $w$ & Page width \\ $P$ & Ratio of page height to width \\ $T$ & Ratio of text block height to width \\ $S$ & Ratio of spine width to page width \\ $H$ & Ratio of top margin height to spine width \\ $E$ & Ratio of fore edge margin width to spine width \\ $F$ & Ratio of bottom margin height to spine width \\ $G$ & Ratio of width of two-column gutter to spine width \\ \hline \end{tabular} \end{table} Given values for $w$, $P$, $T$, $S$, and any two of $H$, $E$ and $F$, it is possible to calculate the page size, the text block size and the position of the text. The command \\ \verb|\drawaspread[|\meta{F}\verb|]{|% \meta{w}\verb|}{|% \meta{P}\verb|}{|% \meta{T}\verb|}{|% \meta{S}\verb|}{|% \meta{H}\verb|}{|% \meta{E}\verb|}{|% \meta{G}\verb|}|\ixcom{drawaspread} \\ where the first parameter is optional, draws a two page spread with the given page width and proportions. If the optional \meta{F} is not provided, then the bottom margin is calculated from the values of other parameters. If \meta{G} is zero or negative, then a single column layout is shown, otherwise a double column layout is presented. \newlength{\pwlayi} \setlength{\pwlayi}{0.4375\textwidth} \newlength{\pwlayii} \setlength{\pwlayii}{0.5\pwlayi} \begin{figure} \centering \begin{minipage}[b]{\pwlayi} \drawaspread{\pwlayii}{1.294}{1.618}{0.176}{1.037}{1.685}{0} \end{minipage} \hfill \begin{minipage}[b]{\pwlayi} \drawaspread{\pwlayii}{1.5}{1.5}{0.111}{1.5}{2.0}{0} \end{minipage} \caption{(Left) The \LaTeX{} book spread; (Right) Spread for many of Gutenberg's books} \label{fig:spread} \end{figure} Figure~\ref{fig:spread} shows two different spreads. This was produced from the code below: \begin{verbatim} \newlength{\pwlayi} \setlength{\pwlayi}{0.4375\textwidth} \newlength{\pwlayii} \setlength{\pwlayii}{0.5\pwlayi} \begin{figure} \centering \begin{minipage}[b]{\pwlayi} \drawaspread{\pwlayii}{1.294}{1.618}{0.176}{1.037}{1.685}{0} \end{minipage} \hfill \begin{minipage}[b]{\pwlayi} \drawaspread{\pwlayii}{1.5}{1.5}{0.111}{1.5}{2.0}{0} \end{minipage} \caption{(Left) The \LaTeX{} book spread; (Right) Spread for many of Gutenberg's books} \label{fig:spread} \end{figure} \end{verbatim} The \pixcom{drawaspread} command does not scale via the \pixcom{setlayoutscale} command. The size of the illustration is controlled by the value given for the width of the page. %%%%%%%%%%%%%%% \clearpage \section{Page layout} \suppressfloats[t] %%\drawmarginparsfalse %%%%%%%%%%%%%%%%%%%%% %%\printheadingstrue %\printheadingsfalse %%\printparameterstrue %\printparametersfalse %\drawdimensionstrue %%\drawdimensionsfalse %%%%%%%%%%%%%%%%%%%%% The layout of a single page is produced by the \pixcom{pagediagram} or \pixcom{pagedesign} (or \pixcom{drawpage}) command. The kind of page drawn is specified via three control commands\footnote{Remember that all drawing commands of the form \pcom{draw...}, except for \pcom{drawaspread}, are also controlled by the \pcom{drawparameters...} command.}. Right- or left-hand page layouts are specified by the commands \pcom{oddpagelayout}\TF{} (\pixcom{oddpagelayouttrue} for an odd-numbered (i.e., right-hand) page, or \pixcom{oddpagelayoutfalse} for an even-numbered (i.e., left-hand or verso) page). The default is \pixcom{oddpagelayouttrue}. Double or single column layouts are controlled by the commands \pcom{twocolumnlayout}\TF. Using \pixcom{twocolumnlayouttrue} will result in a picture of a double column page layout and using \pixcom{twocolumnlayoutfalse} will result in a picture of a single column page layout. The default is \pixcom{twocolumnlayoutfalse}. The display of marginal notes is controlled by the commands \pcom{drawmarginpars}\TF. Using \pixcom{drawmarginparstrue} rusults in representations of marginal notes being drawn and using \pixcom{drawmarginparsfalse} hides the marginal notes. The default is \pixcom{drawmarginparstrue}. Normally \LaTeX{} places any marginal notes in the outside margin; the standard \LaTeX{} command \pixcom{reversemarginpar} causes notes to be placed in the opposite margin to the default one, and \pixcom{normalmarginpar} causes the notes to be put in the default margin. The package commands \pcom{reversemarginpar}\TF{} may be used to control the marginal note locations in the pictures. \pixcom{reversemarginpartrue} corresponds to \pixcom{reversemarginpar} and \pixcom{reversemarginparfalse} corresponds to \pixcom{normalmarginpar}. The package default is \pixcom{reversemarginparfalse}. A \LaTeX{} class may always place marginal notes into the same margin. The package command \pcom{marginparswitch}\TF, is supplied to control the placement in the diagrams. \pixcom{marginparswitchtrue} will place marginal notes according to the class desires, while \pixcom{marginparswitchfalse} will always draw marginal notes in one margin. As an example, \fref{fig:pplt} is produced by the following code. \begin{verbatim} \begin{figure} \oddpagelayoutfalse \twocolumnlayouttrue \pagediagram \caption{Left-hand two-column page layout parameters} \label{fig:pplt} \end{figure} \end{verbatim} \begin{figure} \oddpagelayoutfalse \twocolumnlayouttrue %\drawpage \pagediagram \caption{Left-hand two-column page layout parameters} \label{fig:pplt} \end{figure} The two lines forming an inverted `L' represent the left-hand and top of the printed sheet. By default, \LaTeX{} makes all page layout measurements from a point located one inch in from the left-hand side of the printed sheet and one inch down from the top of the sheet. This point is marked with a circle. The dashed lines correspond to the vertical and horizontal offsets from this point. The command \pixcom{currentpage} collects together the page parameter settings for the current document for the page on which it is issued. For example, it determines whether the current page is odd or even and in which margin any marginal notes would be placed. \fref{fig:ptrs} shows the odd page layout for the document you are now reading. It was produced by the following commands: \begin{verbatim} \begin{figure} \currentpage \oddpagelayouttrue \pagedesign \caption{Odd page layout for this document} \label{fig:ptrs} \end{figure} \end{verbatim} The resulting picture is correctly proportioned, both horizontally and vertically. \begin{figure} \currentpage %\drawparametersfalse \drawpage \pagedesign \caption{Page layout for this document} \label{fig:ptrs} \end{figure} When layouts are drawn with \verb|...diagram|\footnote{Or longhandedly with \pcom{drawparametersfalse} and \pcom{draw...}.} the actual values of the parameters used to produce the layout are normally listed at the bottom of the picture. This can be used, as in \fref{fig:ptrs}, to find out what the settings are for the current document. Among other parameters that are set by \pixcom{currentpage} are values for the page width and height. If these have been specified by the \pixcom{paperwidth} and \pixcom{paperheight} commands, these values are used. Otherwise the width and height are set to the size of American letter paper, which is eight by eleven and a half inches. \begin{table} \centering \caption{Commands for setting trial page parameters}\label{tab:tpage} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{trypaperwidth} & sets the \pixcom{paperwidth} value \\ \pixcom{trypaperheight} & sets the \pixcom{paperheight} value \\ \pixcom{tryhoffset} & sets the \pixcom{hoffset} value (usually 0pt) \\ \pixcom{tryvoffset} & sets the \pixcom{voffset} value (usually 0pt) \\ \pixcom{tryoddsidemargin} & sets the \pixcom{oddsidemargin} (usually 21--63pt) \\ \pixcom{tryevensidemargin} & sets the \pixcom{evensidemargin} value (usually 39--82pt) \\ \pixcom{trymarginparwidth} & sets the \pixcom{marginparwidth} value (usually 68--107pt) \\ \pixcom{trymarginparsep} & sets the \pixcom{marginparsep} value (usually 10--11pt) \\ \pixcom{trymarginparpush} & sets the \pixcom{marginparpush} value (usually 5--7pt) \\ \pixcom{trytopmargin} & sets the \pixcom{topmargin} value (usually 27pt) \\ \pixcom{tryheadheight} & sets the \pixcom{headheight} value (usually 12pt) \\ \pixcom{tryheadsep} & sets the \pixcom{headsep} value (usually 25pt) \\ \pixcom{tryfootskip} & sets the \pixcom{footskip} value (usually 30pt) \\ \pixcom{trytextheight} & sets the \pixcom{textheight} value (usually 36--43 times the \pixcom{baselineskip}) \\ \pixcom{trytextwidth} & sets the \pixcom{textwidth} value (usually 345--390pt) \\ \pixcom{trycolumnsep} & sets the \pixcom{columnsep} value (usually 10pt) \\ \pixcom{trycolumnseprule} & sets the \pixcom{columnseprule} value (usually 0pt) \\ \hline \end{tabular} \end{table} There are a set of commands for experimenting with the page layout parameters. They are listed in \tref{tab:tpage}. Each of these commands takes one argument which is a length value. There is, in addition, an odd command, \pixcom{setfootbox}\verb|{|\meta{height}\verb|}{|\meta{depth}\verb|}|, which may be used to specify the expected \meta{height} and \meta{depth} of the footer. Footers are typically a single line but may require more space than that. Note that there is no way to actually specify the vertical size of the footer in LaTeX, which will use as much space as it needs. If a footer is given a \meta{depth} then a dashed line is drawn at \pixcom{footskip} below the main text box. The following code provides an example of the use of some of these commands when trying an experimental page layout. The result is shown in \fref{fig:pudf}. Note that \pixcom{currentpage} is used to initialize all the appropriate parameter values before setting any trial values. \begin{verbatim} \begin{figure} \currentpage \trypaperwidth{11in} \trypaperheight{8.5in} \trytextwidth{500pt} \trycolumnsep{40pt} \trycolumnseprule{3pt} \tryhoffset{-0.5in} \tryvoffset{0.5in} \printheadingsfalse \drawdimensionstrue \twocolumnlayouttrue \pagedesign \caption{An experimental page layout}\label{fig:pudf} \end{figure} \end{verbatim} \begin{figure} \currentpage \trypaperwidth{11in} \trypaperheight{8.5in} \trytextwidth{500pt} \trycolumnsep{40pt} \trycolumnseprule{3pt} \tryhoffset{-0.5in} \tryvoffset{0.5in} \printheadingsfalse \drawdimensionstrue \twocolumnlayouttrue %\drawparametersfalse \drawpage \pagedesign \caption{An experimental page layout}\label{fig:pudf} \end{figure} As can be seen, the resulting layout runs off the bottom of the specified physical page; either because the page dimensions were incorrectly set (the designer getting a landscape page when a portrait page was desired), or because the text height and width parameters were set incorrectly for the physical page (probably satisfactory for a portrait page but certainly wrong for the landscape page). Note that \pixcom{printheadingsfalse} was used to delete the explanatory heading text, and dimensions were drawn because of \pixcom{drawdimensionstrue}. \clearpage \subsection{Changing the page layout in your document} You can only specify the page layout in a document's preamble. That is, it is set by the class, or by a package or per document via code you write in the preamble. To be on the safe side and avoid strange error messages like \texttt{You can't use `\bs spacefactor'\ixcom{spacefactor} in vertical mode}, enclose all your preamble commands within the command pair \pixcom{makeatletter} and \pixcom{makeatother}. The page layout parameters can all be changed using the \LaTeX{} \pixcom{setlength} command. For example, to set the width of the text to 3~inches, put this into the preamble: \begin{verbatim} \makeatletter \setlength{\textwidth}{3in} \makeatother \end{verbatim} The \pixcom{pagevalues} command can be used to produce a table, as shown here, of the values of the current document's page layout parameters. This is the default tabulation. \begin{verbatim} \pagevalues \end{verbatim} \pagevalues \begin{quote} \textbf{Note:} Prior to version 2.5 the tabulations were set in a \pixenv{center} environment. Starting with version 2.5 there is no surrounding environment. \end{quote} %%%%%%%%%%%%%%% \clearpage \section{The \file{memoir} class page layout} \suppressfloats[t] %%\drawmarginparsfalse The \file{memoir} class~\cite{MEMOIR} provides a different set of page layout parameters than the standard LaTeX classes. The layout of a single page for this class is produced by the \pixcom{stockdiagram} and \pixcom{stockdesign} (or \pixcom{drawstock}) commands. The kind of page drawn is specified via the same control commands that are used by the page drawing commands. That is: \\ \pcom{oddpagelayout}\TF, \\ \pcom{twocolumnlayout}\TF, \\ \pcom{drawmarginpars}\TF, \\ \pcom{reversemarginpar}\TF, and \\ \pcom{marginparswitch}\TF. Generally speaking, the commands for displaying and experimenting with the layout of a \file{memoir} class page are the same as, or analagous to, those for a standard page layout. As an example, \fref{fig:mempplt} is produced by the following code. \begin{verbatim} \begin{figure} \oddpagelayouttrue \twocolumnlayoutfalse \stockdiagram \caption{Right-hand page major layout parameters for the \file{memoir} class} \label{fig:mempplt} \end{figure} \end{verbatim} \begin{figure} \oddpagelayouttrue \twocolumnlayoutfalse %\drawmarginparsfalse \drawstock \stockdiagram \caption{Right-hand page major layout parameters for the \file{memoir} class} \label{fig:mempplt} \end{figure} Like the \pixcom{currentpage} command, \pixcom{currentstock} collects together the page parameter settings for the current \file{memoir} class document. For information on how to design a page layout the class documentation provides all the details~\cite{MEMOIR} (and uses the \file{layouts} package to illustrate them). \begin{table} \centering \caption{Commands for setting trial \file{memoir} page parameters}\label{tab:tmempage} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{trystockwidth} & sets the \pixcom{stockwidth} value \\ \pixcom{trystockheight} & sets the \pixcom{stockheight} value \\ \pixcom{trypaperwidth} & sets the \pixcom{paperwidth} value \\ \pixcom{trypaperheight} & sets the \pixcom{paperheight} value \\ \pixcom{trytrimedge} & sets the \pixcom{trimedge} value \\ \pixcom{trytrimtop} & sets the \pixcom{trimtop} value \\ \pixcom{tryspinemargin} & sets the \pixcom{spinemargin} (usually 21--63pt) \\ \pixcom{trymarginparwidth} & sets the \pixcom{marginparwidth} value (usually 68--107pt) \\ \pixcom{trymarginparsep} & sets the \pixcom{marginparsep} value (usually 10--11pt) \\ \pixcom{trymarginparpush} & sets the \pixcom{marginparpush} value (usually 5--7pt) \\ \pixcom{tryuppermargin} & sets the \pixcom{uppermargin} value (usually 27pt) \\ \pixcom{tryheadheight} & sets the \pixcom{headheight} value (usually 12pt) \\ \pixcom{tryheadsep} & sets the \pixcom{headsep} value (usually 25pt) \\ \pixcom{tryfootskip} & sets the \pixcom{footskip} value (usually 30pt) \\ \pixcom{trytextheight} & sets the \pixcom{textheight} value (usually 36--43 times the \pixcom{baselineskip}) \\ \pixcom{trytextwidth} & sets the \pixcom{textwidth} value (usually 345--390pt) \\ \pixcom{trycolumnsep} & sets the \pixcom{columnsep} value (usually 10pt) \\ \pixcom{trycolumnseprule} & sets the \pixcom{columnseprule} value (usually 0pt) \\ \hline \end{tabular} \end{table} There are a set of commands for experimenting with the page layout parameters. They are listed in \tref{tab:tmempage}. Each of these commands takes one argument which is a length value. The \pixcom{setfootbox} command may be used as well. The following code provides an example of the use of some of these commands when trying an experimental page layout. The result is shown in \fref{fig:pmemudf}. \begin{verbatim} \begin{figure} \currentstock \trystockheight{11in} \trystockwidth{8.5in} \trytrimtop{1in} \trytrimedge{1in} \trypaperheight{10in} \trypaperwidth{7.5in} \tryspinemargin{0.75in} \tryuppermargin{1.0in} \tryheadheight{12pt} \tryheadsep{24pt} \trytextwidth{5in} \trytextheight{7in} \tryfootskip{24pt} \setfootbox{50pt}{50pt} \trymarginparsep{17pt} \trymarginparwidth{62pt} \trymarginparpush{12pt} \setlabelfont{\small} \stockdesign \caption{An experimental \file{memoir} class page layout}\label{fig:pmemudf} \end{figure} \end{verbatim} \begin{figure} \currentstock \trystockheight{11in} \trystockwidth{8.5in} \trytrimtop{1in} \trytrimedge{1in} \trypaperheight{10in} \trypaperwidth{7.5in} \tryspinemargin{0.75in} \tryuppermargin{1.0in} \tryheadheight{12pt} \tryheadsep{24pt} \trytextwidth{5in} \trytextheight{7in} \tryfootskip{24pt} \setfootbox{50pt}{50pt} \trymarginparsep{17pt} \trymarginparwidth{62pt} \trymarginparpush{12pt} \printheadingsfalse %%\twocolumnlayouttrue %%\oddpagelayoutfalse \setlabelfont{\small} %\drawparametersfalse \drawstock \stockdesign \caption{An experimental \file{memoir} class page layout}\label{fig:pmemudf} \end{figure} There is also a \pixcom{stockvalues} command to print a tabulation of the current stock specifications. % As this manual does not use the \file{memoir} % class, calling it would only result in errors. %%%%%%%%%% \clearpage \section{Paragraph layout} \suppressfloats[t] The commands \pixcom{paragraphdiagram} and \pixcom{paragraphdesign} (or \pixcom{drawparagraph} ) can be used to visualize the parameters that affect paragraphing. This is illustrated in \fref{fig:fpara} which was produced by the following code: \begin{verbatim} \begin{figure} \paragraphdiagram \caption{Paragraph parameters}\label{fig:fpara} \end{figure} \end{verbatim} \begin{figure} %\drawparagraph \paragraphdiagram \caption{Paragraph parameters}\label{fig:fpara} \end{figure} The command \verb|\currentparagraph|\ixcom{currentparagraph} sets the drawing parameters to the settings for the current document. The commands listed in \tref{tab:para} can be used to set trial values for the relevant parameters. These commands take one argument which must be a length. \begin{table} \centering \caption{Commands for setting trial paragraph parameters}\label{tab:para} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{tryparindent} & sets the \pixcom{parindent} value \\ \pixcom{tryparskip} & sets the \pixcom{parskip} value \\ \pixcom{tryparlinewidth} & sets the \pixcom{linewidth} value \\ \pixcom{tryparbaselineskip} & sets the \pixcom{baselineskip} value \\ \hline \end{tabular} \end{table} Figure~\ref{fig:dpara} shows the paragraphing as used in this document.

It isn't demonstrated in this typescript but you can see the effect in \fref{fig:mpara} which was produced from: \begin{verbatim} \currentparagraph \begin{figure} \tryparindent{-4em} \paragraphdesign \caption{An outset paragraph}\label{fig:mpara} \end{figure} \end{verbatim} The \pixcom{paragraphvalues} command can be used to produce a table, shown below, of the values of the current document's paragraph layout parameters (as set at the time that the command is used). The tabulation was typeset via \begin{verbatim} \begin{center} \printinunitsof{mm} \paragraphvalues \end{center} \end{verbatim} Note the use of \pixcom{printinunitsof} to set millimetres as the unit of length. \begin{center} \printinunitsof{mm} \paragraphvalues \end{center} %%%%%%%%% \clearpage \section{Float layouts} \suppressfloats[t] Two sets of commands are provided for displaying the layouts of \LaTeX{} floats (e.g., the \pixenv{figure} and \pixenv{table} environments). One set is for a macro view of floats and the other is for a more detailed view. \subsection{Float and text page layout} This set of commands is for displaying the general parameters for the location of floats on a page and proportioning the available space between the floats and textual material. The commands \pixcom{floatpagediagram} and \pixcom{floatpagedesign} (or \pixcom{drawfloatpage}) are used to visualize the general parameters. These are illustrated in \fref{fig:fpp} which was produced by the following code: \begin{verbatim} \begin{figure} \floatpagediagram \caption{Float and text page parameters}\label{fig:fpp} \end{figure} \end{verbatim} \begin{figure} %\drawfloatpage \floatpagediagram \caption{Float and text page parameters}\label{fig:fpp} \end{figure} The command \pixcom{currentfloatpage} sets the drawing parameters to the settings for the current document. The `standard' \LaTeX{} settings are shown in \fref{fig:fpstd}, produced by the code below. \begin{verbatim} \begin{figure} \currentfloatpage \trytotalnumber{3} \trytopnumber{2} \trytopfraction{0.7} \trytextfraction{0.2} \trybottomfraction{0.3} \trybottomnumber{1} \setlayoutscale{0.25} \floatpagedesign \caption{The standard \LaTeX{} float and text page settings} \label{fig:fpstd} \end{figure} \end{verbatim} \begin{figure} \currentfloatpage \trytotalnumber{3} \trytopnumber{2} \trytopfraction{0.7} \trytextfraction{0.2} \trybottomfraction{0.3} \trybottomnumber{1} \setlayoutscale{0.25} %\drawparametersfalse \drawfloatpage \floatpagedesign \caption{The standard \LaTeX{} float and text page settings} \label{fig:fpstd} \end{figure} The commands listed in \tref{tab:tfloatp} can be used to set trial values for the relevant parameters. The commands take one argument, which is either an integer number or a decimal fraction, depending on the particular command. \begin{table} \centering \caption{Commands for setting trial float page parameters}\label{tab:tfloatp} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{trytotalnumber} & (integer) sets the \pixcom{totalnumber} (usually 3) \\ \pixcom{trytopnumber} & (integer) sets the \pixcom{topnumber} (usually 2) \\ \pixcom{trytopfraction} & (decimal) sets the \pixcom{topfraction} (usually 0.7) \\ \pixcom{trytextfraction} & (decimal) sets the \pixcom{textfraction} (usually 0.2) \\ \pixcom{trybottomnumber} & (integer) sets the \pixcom{bottomnumber} (usually 1) \\ \pixcom{trybottomfraction} & (decimal) sets the \pixcom{bottomfraction} (usually 0.3) \\ \hline \end{tabular} \end{table} \begin{figure} \currentfloatpage \trytotalnumber{4} \trytopnumber{2} \trytopfraction{0.9} \trytextfraction{0.1} \trybottomnumber{2} \trybottomfraction{0.6} \setlayoutscale{0.25} %\drawparametersfalse \drawfloatpage \floatpagedesign \caption{Float page layout for decreasing likelihood of float-only pages} \label{fig:fpudf} \end{figure} Figure~\ref{fig:fpudf} illustrates float page settings that increase the likelihood of a float remaining on a text page without being put on a page by itself. The figure was produced from the following code: \begin{verbatim} \begin{figure} \currentfloatpage \trytotalnumber{4} \trytopnumber{2} \trytopfraction{0.9} \trytextfraction{0.1} \trybottomnumber{2} \trybottomfraction{0.6} \setlayoutscale{0.25} \floatpagedesign \caption{Float page layout for decreasing likelihood of float-only pages} \label{fig:fpudf} \end{figure} \end{verbatim} %%%%%%%%% %%%%\clearpage \subsection{Detailed float layout} \suppressfloats[t] The other view of floats concentrates on the spacing between text and floats on a page. The \pixcom{floatdiagram} and \pixcom{floatdesign} (or \pixcom{drawfloat}) commands are used to visualize this aspect. The relevant parameters are shown in \fref{fig:flp}, produced from the following code: \begin{verbatim} \begin{figure} \setlayoutscale{0.9} \floatdiagram \caption{Float parameters}\label{fig:flp} \end{figure} \end{verbatim} \begin{figure} \setlayoutscale{0.9} %\drawfloat \floatdiagram \caption{Float parameters}\label{fig:flp} \end{figure} As usual, the command \pixcom{currentfloat} sets the trial float parameters to those in effect for the current document. \begin{figure} \currentfloat \tryintextsep{\intextsep} \trytopfigrule{0.5pt} \trybotfigrule{1pt} \setlayoutscale{0.9} %\drawparametersfalse \drawfloat \floatdesign \caption{Float layout with rules}\label{fig:fludf} \end{figure} The commands listed in \tref{tab:tfloat}, all of which take a length argument, set trial values for the float parameters. \begin{table} \centering \caption{Commands for setting trial float parameters}\label{tab:tfloat} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{trytextfloatsep} & sets the \pixcom{textfloatsep} value (usually 20pt) \\ \pixcom{tryfloatsep} & sets the \pixcom{floatsep} value (usually 12pt) \\ \pixcom{tryintextsep} & sets the \pixcom{intextsep} value (usually 12pt) \\ \pixcom{trytopfigrule} & sets the thickness of a \pixcom{topfigrule} (usually 0pt) \\ \pixcom{trybotfigrule} & sets the thickness of a \pixcom{botfigrule} (usually 0pt) \\ \hline \end{tabular} \end{table} The following code, used to produce \fref{fig:fludf}, shows the use of some of these commands: \begin{verbatim} \begin{figure} \currentfloat \tryintextsep{\intextsep} \trytopfigrule{0.5pt} \trybotfigrule{1pt} \setlayoutscale{0.9} \floatdesign \caption{Float layout with rules}\label{fig:fludf} \end{figure} \end{verbatim} The \pixcom{topfigrule} and \pixcom{botfigrule} are little known \LaTeX{} commands; they are not discussed by Lamport~\cite{LAMPORT94} but are described by Goossens \emph{et al}~\cite{GOOSSENS94}. They are like the \pixcom{footnoterule} command in that they draw a rule, or other decoration, below floats at the top of a page (\pixcom{topfigrule}) and above floats at the bottom of a page (\pixcom{botfigrule}). Both these commands have been defined in the preamble to this document as: \begin{verbatim} \makeatletter \newlength{\figrulesep} \setlength{\figrulesep}{0.5\textfloatsep} \newcommand{\topfigrule}{\vspace*{-1pt}% \noindent\rule[-\figrulesep]{\columnwidth}{1pt}} \newcommand{\botfigrule}{\vspace*{-2pt}% \noindent\rule[\figrulesep]{\columnwidth}{2pt}} \makeatother \end{verbatim} Their effect can be seen throughout the printed result. The typical thickness for a \pixcom{rule} is $0.4$pt; the thickness of these rules has been exagerated in order to make them more noticeable. The \pixcom{topfigrule} is drawn immediately after the top floats before the \pixcom{textfloatsep} spacing is applied. Similarly the \pixcom{botfigrule} is drawn after the \pixcom{textfloatsep} is applied for the bottom floats. Whatever is drawn as a \texttt{...figrule} should take no vertical space, hence the use of negative vertical space in their definitions above. Note that the rules have been given either positive or negative vertical offsets to ensure some space between a float and the rule. \subsection{Changing the float layout in your document} The \verb|\...number| commands are changed with the \LaTeX{} \pixcom{setcounter} command, while the \verb|\...fraction| commands have to be changed via the \pixcom{renewcommand}. For example, the preamble to this document contains the following (enclosed within \pixcom{makeatletter} and \pixcom{makeatother} commands): \begin{verbatim} \setcounter{topnumber}{2} \setcounter{bottomnumber}{2} \setcounter{totalnumber}{4} \renewcommand{\topfraction}{0.9} \renewcommand{\bottomfraction}{0.6} \renewcommand{\textfraction}{0.1} \end{verbatim} Note that there are also the commands: \begin{itemize} \item \pixcom{dbltopnumber} for setting the maximum number of two-column floats at the top of a two-column page (typically 2); \item \pixcom{dbltopfraction} for setting the maximum fraction of a two column page that can be occupied by the top two-column floats (typically 0.7); and \item \pixcom{dblfloatpagefraction} for setting the minimum fraction of a page that has to be occupied by two-column floats before a `float only' page is produced (typically 0.5). \end{itemize} The \verb|\...sep| commands are changed using the \pixcom{setlength} command. The separation values should have a little bit of give in them, that is, they should be rubber lengths. A typical set of values might be specified as: \begin{verbatim} \setlength{\floatsep}{12pt plus 2pt minus 2pt} \setlength{\textfloatsep}{20pt plus 2pt minus 4pt} \setlength{\intextsep}{\floatsep} \end{verbatim} There are corresponding separation commands for two-column floats at the top or bottom of a page. These are \pixcom{dblfloatsep} for inter-float separation and \pixcom{dbltextfloatsep} for spacing between a two-column float and the text area. \floatvalues The \pixcom{floatvalues} command can be used to produce a table, as shown here, of the values of the current document's float layout parameters (as set at the time that the command is used). %%%%%% \clearpage \section{List layout} \suppressfloats[t] The commands \pixcom{listdiagram} and \pixcom{listdesign} (or \pixcom{drawlist}), as their names suggest, display the layout of list\ixenv{list} environments. The list parameters are shown in \fref{fig:lstp}, which was produced by the following code: \begin{verbatim} \begin{figure} \listdiagram \caption{List parameters} \label{fig:lstp} \end{figure} \end{verbatim} The list layout may be controlled by the \verb|\listaspara|\TF{} commands. Use \pixcom{listasparatrue} for displaying the list when it is being treated as a paragraph, otherwise use \pixcom{listasparafalse}. The default is \pixcom{listasparatrue}. \begin{figure} %\drawlist \listdiagram \caption{List parameters} \label{fig:lstp} \end{figure} The command \pixcom{currentlist} extracts the list parameters from the current environment for display via \pixcom{drawlist}. Figure~\ref{fig:lstenum} graphically illustrates the layout for an \pixenv{enumerate} type list. The figure was generated by the following code: \begin{verbatim} \begin{enumerate} \item Figure~\ref{fig:lstenum} illustrates the layout of an \texttt{enumerate} list. \currentlist \begin{figure} \listdesign \caption{Layout of an \texttt{enumerate} list} \label{fig:lstenum} \end{figure} \end{enumerate} \end{verbatim} \begin{enumerate} \item Figure~\ref{fig:lstenum} illustrates the layout of an \texttt{enumerate} list. \currentlist \begin{figure} % \drawparametersfalse \drawlist \listdesign \caption{Layout of an \texttt{enumerate} list} \label{fig:lstenum} \end{figure} \end{enumerate} Note that \pixcom{currentlist} was called within the list environment in order to pick up the desired parameter values. Table~\ref{tab:tlist} gives a listing of the commands that are provided for experimenting with the list layout parameters. Each of these commands takes a length as its argument. \begin{table} \centering \caption{Commands for setting trial list parameters} \label{tab:tlist} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{tryitemindent} & sets the \pixcom{itemindent} value \\ \pixcom{trylabelwidth} & sets the \pixcom{labelwidth} value \\ \pixcom{trylabelsep} & sets the \pixcom{labelsep} value \\ \pixcom{tryleftmargin} & sets the \pixcom{leftmargin} value \\ \pixcom{tryrightmargin} & sets the \pixcom{rightmargin} value \\ \pixcom{trylistparindent} & sets the \pixcom{listparindent} value \\ \pixcom{trytopsep} & sets the \pixcom{topsep} value \\ \pixcom{tryparskip} & sets the \pixcom{parskip} value \\ \pixcom{trypartopsep} & sets the \pixcom{partopsep} value \\ \pixcom{tryparsep} & sets the \pixcom{parsep} value \\ \pixcom{tryitemsep} & sets the \pixcom{itemsep} value \\ \hline \end{tabular} \end{table} \newenvironment{listX}% {\begin{list}{item}% {\setlength{\itemindent}{-30pt}% \setlength{\labelwidth}{80pt}% \setlength{\labelsep}{1em}% \setlength{\leftmargin}{170pt}% \setlength{\rightmargin}{-40pt}% \setlength{\listparindent}{80pt}% \setlength{\topsep}{3ex}% \setlength{\partopsep}{\topsep}% \setlength{\parsep}{\topsep}% \setlength{\itemsep}{\topsep}% }% }% {\end{list}} Figure~\ref{fig:lstudf} shows the layout of a user-defined list. An example of the list as it would appear in a document is shown by the list that follows this paragraph. \begin{listX} \item[ListX, first item:] This is an example of a user-defined list. The appearance is somewhat different from that normally seen in \LaTeX{} lists. Note that the text extends into the normal right-hand margin. Also, the body of the list text is indented from the label. No claim is made that there is anything aesthetic about the design of the list. In fact, I think that it is pretty awful. It is merely provided as an example of a non-standard list and so that the \pixcom{drawlist} command can be shown off. \item[ListX, second item:] Now we will draw the layout of this list from within itself (see \fref{fig:lstudf} for the result). The code used is: \begin{verbatim} \currentlist \begin{figure} \drawdimensionstrue \listdesign \caption{The layout of the \texttt{listX} environment} \label{fig:lstudf} \end{figure} \end{verbatim} \currentlist \begin{figure} \drawdimensionstrue %\drawparametersfalse \drawlist \listdesign \caption{The layout of the \texttt{listX} environment} \label{fig:lstudf} \end{figure} \item[ListX, third item:] The definition of this list environment is: \begin{verbatim} \newenvironment{listX}% {\begin{list}{item}% {\setlength{\itemindent}{-30pt}% \setlength{\labelwidth}{80pt}% \setlength{\labelsep}{1em}% \setlength{\leftmargin}{170pt}% \setlength{\rightmargin}{-40pt}% \setlength{\listparindent}{80pt}% \setlength{\topsep}{3ex}% \setlength{\partopsep}{\topsep}% \setlength{\parsep}{\topsep}% \setlength{\itemsep}{\topsep}% }% }% {\end{list}} \end{verbatim} \end{listX} In \LaTeX{} many display environments, such as the \pixenv{quotation} environment, are defined in terms of the generic \pixenv{list} environment, so the settings for these may also be explored with \pixcom{currentlist}. For example, the following code shows how to determine the `list' settings for the \pixenv{thebibliography} environment (with apologies to Leslie Lamport). \begin{verbatim} \begin{thebibliography}{Dillo 83} \bibitem[Knud 66]{kn:gnus} D. E. Knudson. \emph{1996 World Gnus Almanac.} \currentlist \begin{figure} \listdesign \caption{Bibliography list} \end{figure} \end{thebibliography} \end{verbatim} Running this code is left as an exercise for the reader. \subsection{Changing lists} Many of \LaTeX's environments are defined in terms of lists, most noticeably the \pixenv{description}, \pixenv{enumerate} and \pixenv{itemize} environments. To change any of LaTeX's predefined list environments it is probably best to examine their definitions in the appropriate class file (e.g., \pixfile{classes.dtx}) and then put your modified definitions into a package file. \begin{quote} \printinunitsof{pc} \listvalues \end{quote} The \pixcom{listvalues} command can be used to produce a table, as shown here, of the values of the current document's list layout parameters (as set at the time that the command is used). This table was produced by: \begin{verbatim} \begin{quote} \printinunitsof{pc} \listvalues \end{quote} \end{verbatim} %%%%%%%%%%%%%%%%%% \clearpage \section{Sectional heading layout} \suppressfloats[t] In \LaTeX{} a few headings, like \pixcom{part} and \pixcom{chapter} are defined using special definition code. The majority, though, are defined via the internal \LaTeX{} \pixatcom{startsection} command. This command takes 6 arguments: \\ \verb|\@startsection{|\meta{name}\verb|}{|% \meta{level}\verb|}{|% \meta{indent}\verb|}{|% \meta{beforeskip}\verb|}{|% \meta{afterskip}\verb|}{|% \meta{font style}\verb|}|. The commands \verb|\headingdiagram{|\meta{font style}\verb|}|\ixcom{headingdiagram} and \verb|\headingdesign{|\meta{font style}\verb|}|\ixcom{headingdesign} (or \verb|\drawheading{|\meta{font style}\verb|}|\ixcom{drawheading}) draw a picture of the layout for sectional headings based on the \pixatcom{startsection} command. Unlike the other drawing commands it takes one parameter, which is the specification of the size and/or font of the heading. For example, \verb|\drawheading{\large\itshape}|. For \pixcom{headingdiagram} (or \pixcom{drawheading} with \pixcom{drawparameterstrue} is in effect) the parameter has no effect. There are two kinds of headings: \begin{enumerate} \item Display headings, where the heading is set off from the text body, and \item Run-in headings, where the text body starts on the same line as the heading. \end{enumerate} When \pixcom{headingdiagram} is called (or \pixcom{drawheading} with \pixcom{drawparameterstrue} in effect) the pair of commands \pixcom{runinheadtrue} and \pixcom{runinheadfalse} control whether a run-in head or a display head will be illustrated. The default is \pixcom{runinheadfalse}. %%%%%%%%%%%%%%%%%%%%%%% %%\drawdimensionsfalse %%%%%%%%%%%%%%%%%%%%%% Figures~\ref{fig:hdp} and~\ref{fig:hrp} show the parameters of the two kinds of headings. They were produced by the following code: \begin{verbatim} \begin{figure} \setlayoutscale{1} \headingdiagram{ } \caption{Display heading parameters}\label{fig:hdp} \end{figure} \begin{figure} \setlayoutscale{1} \runinheadtrue \headingdiagram{ } \caption{Run-in heading parameters}\label{fig:hrp} \end{figure} \end{verbatim} \begin{figure} \setlayoutscale{1} %\drawheading{ } \headingdiagram{ } \caption{Display heading parameters}\label{fig:hdp} \end{figure} \begin{figure} \setlayoutscale{1} \runinheadtrue %\drawheading{ } \headingdiagram{ } \caption{Run-in heading parameters}\label{fig:hrp} \end{figure} The command \pixcom{currentheading} sets up default parameter values for the illustration of a heading. These values are based on guesstimates of the values of the arguments of the \pixatcom{startsection} command. The commands given in \tref{tab:thead} can be used to explicitly set heading parameters. Each of these commands takes a length for its parameter value. \begin{table} \centering \caption{Commands for setting trial heading parameters}\label{tab:thead} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{trybeforeskip} & sets the \textit{beforeskip} value \\ \pixcom{tryafterskip} & sets the \textit{afterskip} value \\ \pixcom{tryindent} & sets the \textit{indent} value \\ \hline \end{tabular} \end{table} The regular reader of \LaTeX{} documents will have noticed that the \pixcom{subsubsection} headings in this manual do not conform to the usual \LaTeX{} style. In fact, the preamble to this document contains the following definition: \begin{verbatim} \makeatletter \renewcommand{\subsubsection}{\@startsection% {subsubsection}% name {3}% level {0mm}% indent {-\baselineskip}% beforeskip {0.5\baselineskip}% afterskip {\large\itshape}}% style \makeatother \end{verbatim} Note that the \pixcom{makeatletter} and \pixcom{makeatother} commands are required because of the use of the \tat{} character in the name of the \pixatcom{startsection} command. %%%%%%%%%%%%%%%%%%%%%%%% %%\drawdimensionsfalse %%%%%%%%%%%%%%%%%%%%%%% \currentheading \trybeforeskip{-\baselineskip} \tryafterskip{0.5\baselineskip} \tryindent{0mm} \begin{figure} \setlayoutscale{1} %\drawparametersfalse \drawheading{\large\itshape} \headingdesign{\large\itshape} \caption{Subsubsection heading layout parameters for this document} \label{fig:hdudf} \end{figure} Figure~\ref{fig:hdudf} illustrates the layout for this heading, and was produced by the code below. \begin{verbatim} \currentheading \trybeforeskip{-\baselineskip} \tryafterskip{0.5\baselineskip} \tryindent{0mm} \begin{figure} \setlayoutscale{1} \headingdesign{\large\itshape} \caption{Subsubsection layout parameters for this document} \label{fig:hdudf} \end{figure} \end{verbatim} \currentheading \trybeforeskip{-\baselineskip} \tryafterskip{-0.5\baselineskip} \tryindent{0mm} \begin{figure} \setlayoutscale{1} %\drawparametersfalse \drawheading{\large\itshape} \headingdesign{\large\itshape} \caption{Subsubsection layout parameters for a run-in heading} \label{fig:hrudf} \end{figure} The same heading, but specified as a run-in heading by making the value of \textit{afterskip} negative rather than positive, is illustrated in \fref{fig:hrudf}. %%%%%%%%%%%%%%%% \clearpage \section{Footnote layout} \suppressfloats[t] Footnote layouts are produced by the commands \pixcom{footnotediagram} and \pixcom{footnotedesign} (or \pixcom{drawfootnote}). The relevant footnote parameters are shown in \fref{fig:fp}, which was produced by the following code: \begin{verbatim} \begin{figure} \setlayoutscale{0.4} \setlabelfont{\huge\itshape} \footnotediagram \caption{The footnote parameter layout} \label{fig:fp} \end{figure} \end{verbatim} Note the use of \pixcom{setlabelfont} to change the font used for labelling (the `MAIN TEXT' in this case). \begin{figure} \setlayoutscale{0.4} \setlabelfont{\huge\itshape} %\drawfootnote \footnotediagram \caption{The footnote parameter layout} \label{fig:fp} \end{figure} Some of the current settings for the footnote parameters are set by the \pixcom{currentfootnote} command. Guesstimates are provided for the likely value of the \pixcom{baselineskip} that is used within a footnote, and also for the dimension of the footnote rule. Figure~\ref{fig:ftry} shows the default footnote layout, and was produced by the following code: \begin{verbatim} \begin{figure} \currentfootnote \setlayoutscale{0.4} \footnotedesign \caption{The current footnote layout}\label{fig:ftry} \end{figure} \end{verbatim} The resulting picture has all vertical dimensions magnified by a factor of 4 with respect to the horizontal dimensions. \begin{figure} \currentfootnote \setlayoutscale{0.4} %\drawparametersfalse \drawfootnote \footnotedesign \caption{A footnote layout}\label{fig:ftry} \end{figure} Commands for individually setting trial values for footnote parameters are given in \tref{tab:foot}. Except for \pixcom{tryfootrulefrac}, these all take a length as their parameter. The parameter value for \pixcom{tryfootrulefrac} is a decimal number representing a fraction of the \pixcom{textwidth}. The trial length of the footnote rule is set to this fraction of the width of the text block. \begin{table} \centering \caption{Commands for setting trial footnote parameter values}\label{tab:foot} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{tryfootins} & sets the \pixcom{skip}\pixcom{footins} value (usually 10pt) \\ \pixcom{tryfootnotesep} & sets the \pixcom{footnotesep} value (usually 7pt) \\ \pixcom{tryfootnotebaseline} & sets the footnote \pixcom{baselineskip} value \\ \pixcom{tryfootruleheight} & sets the \pixcom{footnoterule} height value (usually 0.4pt) \\ \pixcom{tryfootrulefrac} & sets the length of the \pixcom{footnoterule} \\ \hline \end{tabular} \end{table} \begin{figure} \currentfootnote \tryfootins{10pt} \tryfootnotesep{20pt} \tryfootnotebaseline{15pt} \tryfootruleheight{1pt} \tryfootrulefrac{0.8} \setlayoutscale{0.4} %\drawparametersfalse \drawfootnote \footnotedesign \caption{A user-specified footnote layout} \label{fig:fudf} \end{figure} Figure~\ref{fig:fudf}, produced from the following code, shows an experimental layout for footnotes. \begin{verbatim} \begin{figure} \currentfootnote \tryfootins{10pt} \tryfootnotesep{20pt} \tryfootnotebaseline{15pt} \tryfootruleheight{1pt} \tryfootrulefrac{0.8} \setlayoutscale{0.4} \footnotedesign \caption{A user-specified footnote layout} \label{fig:fudf} \end{figure} \end{verbatim} \subsection{Changing the footnote layout} The value of \pixcom{footnotesep} is changed via the \pixcom{setlength} command. Spacing between the bottom of the text area and the first footnote is normally a rubber length. The following is a typical set of values: \begin{verbatim} \setlength{\footnotesep}{7pt} \setlength{\skip\footins}{10pt plus 4pt minus 2pt} \end{verbatim} For changing other values, see the documented class file \pixfile{classes.dtx}. \footnotevalues The \pixcom{footnotevalues} command can be used to produce a table, as shown here, of the values of the current document's footnote layout parameters (as set at the time that the command is used). %%%%%%%%%%%%%%% \clearpage \section{Table of Contents layout} \suppressfloats[t] The format of an entry in the Table of Contents (ToC) is usually specified by the internal \LaTeX{} \pixatcom{dottedtocline} command: \\ \verb|\@dottedtocline{|% \meta{level}\verb|}{|% \meta{indent}\verb|}{|% \meta{numwidth}\verb|}| \\ where \meta{indent} and \meta{numwidth} relate to the formatting, and an entry will be typeset only if \meta{level} is less than or equal to the value of the \pixcount{tocdepth} counter. The \pixcom{tocdiagram} and \pixcom{tocdesign} (or \pixcom{drawtoc}) commands are used for visualizing the layout of section titles in a \textit{Table of Contents} listing based on the \verb|\@dottedtocline| command, as shown in \fref{fig:tocp}. This was produced by the following code: \begin{verbatim} \begin{figure} \setlayoutscale{0.8} \tocdiagram \caption{Table of Contents entry parameters}\label{fig:tocp} \end{figure} \end{verbatim} \begin{figure} \setlayoutscale{0.8} %\drawtoc \tocdiagram \caption{Table of Contents entry parameters}\label{fig:tocp} \end{figure} \begin{figure} \setlayoutscale{0.8} \currenttoc %\drawparametersfalse \drawtoc \tocdesign \caption{Typical Table of Contents entry for this document} \label{fig:thistoc} \end{figure} Figure~\ref{fig:thistoc} was produced by the following code:\footnote{The drawing of the dotted leader is not completely accurate due to scaling and rounding within the drawing algorithm.} \begin{verbatim} \begin{figure} \setlayoutscale{0.8} \currenttoc \tocdesign \caption{Typical Table of Contents entry for this document} \label{fig:thistoc} \end{figure} \end{verbatim} The command \pixcom{currenttoc} sets values for the ToC parameters based on those for the current document. The paramaters can all be individually adjusted via the commands listed in \tref{tab:toc}. These commands all require a length as their parameter, except for the \pixcom{trytocdotsep} command which takes a number (integer or decimal) as its parameter value. This sets the trial value for the separation between dots in the leader between the sectional title and the page number. The parameter is the separation value in \emph{mu} (math units).\footnote{There are \emph{18mu} units to \emph{1em} unit.} \begin{table} \centering \caption{Commands for setting trial values for ToC parameters}\label{tab:toc} \begin{tabular}{|l|l|} \hline Command & Parameter \\ \hline \pixcom{trytocindent} & sets the \textit{indent} value \\ \pixcom{trytocnumwidth} & sets the \textit{numwidth} value \\ \pixcom{trytoclinewidth} & sets the \pixcom{linewidth} value \\ \pixcom{trytocrmarg} & sets the \pixatcom{tocrmarg} value \\ \pixcom{trytocpnumwidth} & sets the \pixatcom{pnumwidth} value \\ \pixcom{trytocdotsep} & sets the \pixatcom{dotsep} value \\ \hline \end{tabular} \end{table} \begin{figure} \setlayoutscale{0.8} \currenttoc \trytocdotsep{1000} %\drawparametersfalse \drawtoc \tocdesign \caption{Table of Contents entry with a large value for \texttt{\bs @dotsep}} \label{fig:tocudf} \end{figure} Figure~\ref{fig:tocudf}, which was produced by the following code, shows that the effect of having a large value for \pixatcom{dotsep} is to eliminate the dotted leader line between the title text and the page number. \begin{verbatim} \begin{figure} \setlayoutscale{0.8} \currenttoc \trytocdotsep{1000} \tocdesign \caption{Table of Contents entry with a large value for \texttt{\bs @dotsep}} \label{fig:tocudf} \end{figure} \end{verbatim} \subsection{Changing the Table of Contents, etc} The methods of specifying the typesetting of the various entries in a Table of Contents or a List of Figures (or Tables) varies from one kind of entry to another. For details consult the documented class specification file \pixfile{classes.dtx}. However, the \pixatcom{dotsep}, \pixatcom{pnumwidth} and \pixatcom{tocrmarg} values can all be set with the \pixcom{renewcommand}. For example, in the preamble: \begin{verbatim} \makeatletter \renewcommand{\@dotsep}{4.5} \renewcommand{\@pnumwidth}{1.55em} \renewcommand{\@tocrmarg}{2.55em} \makeatother \end{verbatim} Typically, for figure and table captions, and for sectioning commands that are defined using the \pixatcom{startsection} command, table entry typesetting is specified via an \verb|\l@X| command, where \verb|X| is \verb|figure|, \verb|table|, \verb|subsection|, etc., as appropriate. In turn, these commands call the \pixatcom{dottedtocline} command. For example, to change the typesetting for a paragraph entry in the Table of Contents, and for a table caption you should do something like (changing the lengths as appropriate): \begin{verbatim} \makeatletter \renewcommand*{\l@paragraph}{\@dottedtocline{4}{7em}{4em}} \renewcommand*{\l@table}{\@dottedtocline{1}{0em}{3.0em}} \makeatother \end{verbatim} \tocvalues The \pixcom{tocvalues} command can be used to produce a table, as shown here, of the values of the current document's Table of Contents layout parameters (as set at the time that the command is used). \clearpage \section{Font boxing} \setlength{\unitlength}{1pt} Sometimes it is useful to see the size of the box enclosing some text. Two commands are provided for this purpose. The \verb|\drawfontframe{|\meta{text}\verb|}|\ixcom{drawfontframe} produces a drawing of \meta{text} together with its surrounding box drawn. A bullet is placed at the position of the reference point and a horizontal dotted line is drawn along the baseline. The command can be used in normal mode or can be \verb|\put| in a picture environment. \drawfontframe{\Huge\textbf{g}} The framed g was produced by the following code: \begin{verbatim} \drawfontframe{\Huge\textbf{g}} \end{verbatim} The command places the box inside a \texttt{picture} environment that is just big enough to enclose the box. Sometimes it is useful to see the size of the box enclosing some text. Two commands are provided for this purpose. The \verb|\drawfontframelabel{|\meta{text}\verb|}|\ixcom{drawfontframelabel} is similar, except that it labels the reference point, and the width height and depth of the box. The box is placed inside a picture environment that is just big enough to enclose the box. This means that the labels extend beyond the \texttt{picture}. If \verb|\printparameterstrue| is set before issuing the command, the actual values for the width, height and depth of the box are printed in a \texttt{center} environment following the drawing. Here is a simple example created by \verb|\drawfontframelabel{\Huge Q}| with \verb|\printparametersfalse|. \begin{center} \printparametersfalse% \drawfontframelabel{\Huge Q} \end{center} This time with \verb|\printparameterstrue| and \verb|\drawfontframelabel{\Huge\textbf{tangling}}| \begin{center} \printparameterstrue% \drawfontframelabel{\Huge\textbf{tangling}} \end{center} If either of the \verb|\drawfont...| commands are used inside a \texttt{picture} environment, then the \verb|\unitlength| must be set to 1pt, as the drawings are meant to be exact size and the commands assume that all drawing lengths are in terms of pts. Internally, the commands typeset their argument inside a `save box' called \verb|\layoutsbox|\ixsbox{layoutsbox} and then perform the size measurements on \verb|\layoutsbox|. You can use \verb|\layoutsbox| for your own purposes, but if you do so any subsequent use of a \verb|\drawfont...| command will overwrite anything that you might have saved in \verb|\layoutsbox|.
