\section{Introduction}
The \verb"pageframe" document style option was written as an aid
for people who are using \LaTeX\ to make books.  It assumes that
the pages generated by \LaTeX\ are printed on paper larger than the
ultimate trimmed and bound size of the leaves of the book
(for example, pages of a $7{\rm in}\times9{\rm in}$ book printed
on $8\frac12{\rm in}\times11{\rm in}$ paper). The \verb"pageframe"
style option provides the following services:
\begin{itemize}
\item Corner marks to serve as guides in trimming the page to final size
\item An identifying line of text (commonly called a tag line)
      across the top of each printed page,
      outside the final trim area, containing
\begin{itemize}
\item the name of the job that produced the page
      (this is the name of the main input file),
\item the time and date when the job was run,
\item the folio (the number of the page in the document's
      own numbering system---this number may be a roman numeral,
      and it may not be unique within the document), and
\item the absolute sequence number of the sheet within the document
      (this starts at number 1 and increases throughout the document)
\end{itemize}
\item A frame around the trim area of the page
\item Frames around the running head, text body, and footline
\item A grid (of user-specified dimensions) within the text body
\end{itemize}
The tag line and corner marks are always printed; the other
features may be turned on (separately) for draft or proof runs
but would be turned off when the final form of the document is
being generated.

This document illustrates and explains the features that the
\verb"pageframe" style provides.  The pages of the document are printed
with different combinations of the \verb"pageframe" option settings;
you may want to look at the \LaTeX\ source for the document
to see how these are specified.  You will find
a summary of the \verb"pageframe" commands near the end
of this document.

\section{The Page Frame}
The page frame is a rectangle that outlines the entire area of the
final trimmed page.  (The edges of this rectangle therefore line up
with the lines that make up the corner marks.)
It's useful in drafts to allow the designer to see where
the design elements (folios, running heads and feet,
displays, text body, etc.) will fall in relation to the edges
of the printed page.  The page you're now reading
has this frame.  This feature is turned on
by default when the \verb"pageframe" style is used, but you can
turn it off and back on with the commands
\begin{center}
\begin{tabular}{l}
\verb"\pageframefalse"\\
\verb"\pageframetrue"
\end{tabular}
\end{center}
(respectively).
The setting (false=off or true=on) that is in effect when a page
is actually emitted to the \verb"dvi" file (that is, when \LaTeX's
``output routine'' is invoked) is the one that is obeyed, so if you
change this setting partway through a document it may take effect
a page or so before or after you expected.  (This happens because
\TeX\ is typically in the middle of page $n+1$ before it realizes
that it has accumulated enough material to fill page $n$.)

\section{The Inner Skeleton}
The \verb"pageframe" style also allows the designer to outline
the headline, footline, and text body rectangle of a page.
I call this the ``inner skeleton'' of the page (for want of a
better name), and you can turn it on or off with
\begin{center}
\begin{tabular}{l}
\verb"\innerskeltrue"\\
\verb"\innerskelfalse"
\end{tabular}
\end{center}
This feature is off by default, because it's distracting,
but it's useful in the early stages of design when you want
to judge the precise placement of the heads and feet, or
later when you want to see how unusual features like
displayed material or marginal notes fit on the page in relation
to the main text.

When the page frame and inner skeleton are both turned on,
you can see at a glance almost all the parameters that
\LaTeX\ uses to lay out a page.  The width of the text rectangle
is \verb"\textwidth", the distance from the edge of the
text rectangle to the outer edge of the (trimmed) paper is
\verb"\evensidemargin",
and the distance from the text rectangle to the inner edge of the
paper is \verb"\oddsidemargin".  The distance from the top of
the (trimmed) paper to the rule that represents the top of
the page header is \verb"\topmargin", the distance from the top
of the header to the bottom is \verb"\headheight", and the distance
from the bottom of the header to the top of the text rectangle is
\verb"\headsep".  The height of the text rectangle is \verb"\textheight",
the distance from the baseline of the text rectangle to the
baseline of the footer is \verb"\footskip", and the distance
from the top to the bottom of the footer is \verb"\footheight".
The section {\it Things You Need To Know\/} later in this document
has a more detailed discussion of some of these parameters.

The inner skeleton can be turned on
without the page frame, although that seems to me to be
of questionable value.  I can see wanting the page frame
without the inner skeleton, but not vice versa.  However,
the switches are independent.

\innerskelfalse

\section{The Text Grid}
Another optional feature is a grid laid
over\footnote{well, actually under---it's
laid on the page {\em before\/} the text---but you usually
won't be able to tell the difference} the text body.
This can be useful for measuring the leading
(\LaTeX's \verb"\baselineskip" parameter), or space above and
below a display or section head.  The text grid will not be
displayed unless the \verb"innerskel" switch is on.  Even then,
the grid is omitted unless the \verb"textgrid" switch is also on,
which it is by default.  As usual, you can turn it off and on
with the commands
\begin{center}
\begin{tabular}{l}
\verb"\textgridfalse"\\
\verb"\textgridtrue"
\end{tabular}
\end{center}

Although a grid makes it almost impossible to read the text
on a page, it can be useful when you are trying
to gauge parameters that affect the layout of the text
within the text rectangle
(rather than the parameters listed earlier, which
affect the way the larger features of the page --- header,
footer, and text area as a whole --- are arranged).  Text
layout parameters include the \verb"\baselineskip", the
\verb"\parskip", the \verb"\parindent", the \verb"\topskip",
the space above and below section heads
(usually specified in a style file as arguments to the
\verb"\@startsection" macro), space around figures, tables,
and lists, space above footnotes, and many others.

The next two pages show grids of different sizes laid
over the text body.  The first page uses the default grid,
which is composed of squares 10pt on a side.  The grid on the
following page has rectangles 10 picas wide and 15 points high;
this was specified with the command
\begin{center}
\verb"\gridsize{10pc}{15pt}"
\end{center}
The grid size that is in effect when a page is
actually sent to the \verb"dvi" file is the one that is used
for that page.

\pagebreak
\innerskeltrue
\textgridtrue
{\Large
This page has the default grid, which consists of squares 10pt on a side.}

\fourtestpars
\pagebreak
\gridsize{10pc}{15pt}%
{\Large
This page has a grid with vertical lines 10pc apart and
horizontal lines 15pt apart.}

\fourtestpars
%%
\columnsep 2pc
\twocolumn
\textgridfalse
\section{Two-Column Format}
As you can see, the inner skeleton does work on a page in
two-column format, but it still outlines the text body as
a whole (rather than outlining each column separately).
Similarly, a text grid on a two-column page
covers both columns together
(not each column separately).  To treat the columns
as separate objects, I would have had to alter
much more of \LaTeX's output routine than I was
comfortable with.  And that approach still would not
be able to handle \LaTeX\ extensions like
Frank Mittelbach's \verb"multicol" style option, which are
increasingly used instead of \LaTeX's built-in
two-column feature.  So I decided to punt.

The rest of this page is simply filler.

\section{Things You Need To Know}
This section details a few more things you need to know before you
use the \verb"pageframe" document style option.

One of the basic assumptions underlying the \verb"pageframe" code
is that your document is being laid out for back-to-back two-sided
printing (remember, \verb"pageframe" was created primarily to assist in book
production).  As explained below, this assumption is used in calculating
the width of the trimmed pages, so the frame may have the wrong width
if you use \verb"pageframe" with a one-sided document
style.  Note that the standard \LaTeX\ \verb"article" and \verb"report"
document styles both accept \verb"twoside" as an option, so a document
that begins
\begin{center}
\verb"\documentstyle[twoside,pageframe]{article}"
\end{center}
(for example) should come out just fine.

Strictly speaking,
\LaTeX\ doesn't know how wide your page is---it doesn't place anything
on the page to the right of the text body, so it doesn't care how
much farther out the edge of the paper is.  For this reason \LaTeX\ only
provides parameters to specify the widths of the left-hand margins
(\verb"\oddsidemargin" for odd-numbered pages, and \verb"\evensidemargin"
for even-numbered pages).  How then do we figure out where
to put the corner marks and rules that mark the right-hand edge
of the paper?  We do it by assuming that the right-side margin
on a recto (= right-hand-side = odd-numbered) page is equal to
the left-side margin on a verso (= left-hand-side = even-numbered) page,
and vice versa.  This is usually the case, because
otherwise the text rectangles of the pages on the
opposite sides of a leaf wouldn't line up
back-to-back.\footnote{Books are occasionally designed that way,
but it often looks horrible,
because the mass of ink in the text area on the back of a page is usually
dark enough to show through.
That isn't a problem if the text rectangles are aligned, because the text
ink is dark enough that the eye doesn't notice the ``ghost'' from the
other side of the leaf.}
Therefore the \verb"pageframe" style option assumes that the
\verb"\evensidemargin" is the fore-edge margin for all pages (recto
and verso), and the \verb"\oddsidemargin" is the gutter
margin for all pages.\footnote{This is correct: note that the left edge
of a recto page is in the gutter, while the left edge of a verso page
is at the fore-edge.}
It computes the width of a (trimmed) page
to be the sum of the width of the text body (which is given by \LaTeX's
\verb"\textwidth" parameter) and the widths of the fore-edge and gutter
margins.  (I could remove this assumption, having the user instead specify
the page width explicitly, and I will do so if user feedback shows
a demand for this.)


Unfortunately, there is
no parameter, or sum of parameters, that tells us the
total height of a page. Once again, \LaTeX\ doesn't need
to know that.  It simply starts at the top of the page, laying down
space above the header (the \verb"\topmargin"), then the header
(a box of height \verb"\headheight"), then space below the header and
above the text body (the \verb"\headsep"), then the text body
(a box of height \verb"\textheight"), then the footer
(a box of height \verb"\footheight" whose baseline is a distance
\verb"\footskip" below the bottom of the text body).
Since \LaTeX\ places nothing on the page below the footer,
it doesn't care---and doesn't know---how far below the footer
the physical edge of the printed page will fall.
And there's no clever assumption that we can make to figure
it out, as we did in computing the paper width.
The top-to-bottom analogue of the left-to-right reflection argument
given above doesn't work: there's no reason why the distance
below the footer on recto
pages should equal the distance above the header on verso
pages.\footnote{If books were bound across the top
instead of along the side, this would be true---but then
the left and right margins would be
independent and you'd have to specify the width of a page.  You can't win.}
This means that
in order for the bottom corner marks to be placed in the right
positions I had to provide a way for you to specify the
trim height of the paper.
You do it this way:
\begin{center}
\verb"\paperheight{9in}"
\end{center}
This declaration goes in the preamble of your \LaTeX\ document (after
the \verb"\documentstyle" command but before the \verb"\begin{document}"
command).  If you omit it, the rules that outline
the left and right edges of the page in the page frame will disappear,
and the bottom corner marks will abut the footer.

There is a half-truth in the preceding paragraph, regarding the height
of the page footer.  The \LaTeX\ manual does state
(on page 163) that \verb"\footheight" is the height of the
box into which the page's footer is placed, and the code for
\verb"pageframe" acts as if this were so.
But \LaTeX\ doesn't actually work that way.
In fact, the file \verb"latex.tex" contains a comment
to the effect that the \verb"\footheight" parameter is never
used by \LaTeX{}, and this does seem to be the case.
The standard \verb"article", \verb"book", and \verb"report" document
styles do not even specify a value for \verb"\footheight", leaving it
at its default setting of 0pt.  With this setting, the upper and lower
rules drawn by \verb"\innerskeltrue" to demarcate the footer will coincide,
so you'll only see a single line on the page, representing the baseline of
the page footer.  The document you're now reading arbitrarily
sets \verb"\footheight"
to 10pt just to illustrate how the inner skeleton was intended to look,
but you should be aware that it's not a bug in the \verb"pageframe" code
if you see only a single line indicating the position of the footer. 

\setcounter{page}{1}
I reset the page number counter to 1 on this page to demonstrate
that the sheet sequence number in the tag line at the top of a page
is independent of the page number printed on the page.
Even if a book design calls for a roman-numeral page $i$ and
a new page 1 for every part or chapter, there will still
be only one page with sheet number 1.

\pagebreak
\pffont{cmti10}
By default the tag line across the top of the page
is printed in whatever font is current while \LaTeX\ is
loading the \verb"pageframe" style file (this is ordinarily
\verb"cmr10", but some installations might be configured
with different fonts). You can select any font you like for
the tag lines with the \verb"\pffont" command.
I reset the tag line font on this page to \verb"cmti10" by putting
the declaration \verb"\pffont{cmti10}" just before this paragraph.
A tag line font that you declare in this way takes effect as soon as
\LaTeX\ ships out the next page to the \verb"dvi" file, and
remains in effect through the end of the document (unless you
give another \verb"\pffont" command).  Remember that because of the
way output routines work in \TeX\ the next page shipped out
might actually be the page before or after the one on which the
\verb"\pffont" declaration would seem to fall by its position
in the source file.

Observe that the arms of the corner marks do not quite meet,
but are positioned
so that if they were extended to meet, the meeting point would be
the corner of the paper.  The gap allows leeway for
positioning and cutting the paper.  The current version of
\verb"pageframe" doesn't allow you to control the lengths of the
corner marks, the size of the gaps between them and the page corners,
or the distance between the tag line and the top of the page
frame, but it wouldn't be too hard to parametrize these.
I didn't do it because I didn't see a reason to, but I will
if there's demand.

Just in case you're worried about all these extra words and rules
on the page
throwing off the measurements, relax! The code for \verb"pageframe"
uses constructions like \verb"\llap" and \verb"\rlap" to ``hide'' the
height, width, and depth of every mark that it places on the page,
so that the marks placed by your document (text, illustrations,
or whatever) fall into exactly the same positions when you
use \verb"pageframe" as when you don't.

Piet van~Oostrum has written the \verb"fancyheadings" style option
to provide enhanced formatting capabilities for running heads
and feet.  This style option allows for
\begin{itemize}
\item three-part headers and footers
\item rules in header and footer
\item headers and footers wider than \verb|\textwidth|
\item multiline headers and footers
\item separate headers and footers for even and odd pages
\item separate headers and footers for chapter pages
\end{itemize}
To provide extra-wide headers and footers, \verb"fancyheadings"
defines a new dimension parameter, \verb"\headwidth", which it uses
instead of \verb"\textwidth" to specify the widths of the
boxes in which the running heads and feet are constructed.
The \verb"pageframe" style option does not take account of this
new parameter, and continues to draw its rules outlining header
and footer at width \verb"\textwidth".  It would be possible
to make \verb"pageframe" sensitive to \verb"fancyheadings", using
\verb"\headwidth" if \verb"fancyheadings" is in effect and
\verb"\textwidth" otherwise.
I'm willing to do this if there is any demand for it.
(Keep those cards and letters coming in, folks!)

The use of the margin parameters (\verb"\topmargin",
\verb"\evensidemargin", and \verb"\oddsidemargin") calls for
further comment.  The \LaTeX\ manual (on page 163 again) defines
the margin parameters to be ``one inch less than the distance
from the [top or left] edge of the paper'' to the running head
or the text (as appropriate).  Why ``one inch less''?  Well,
it so happens (although the \LaTeX\ manual doesn't tell you this) that
\TeX\ always uses a point one inch down from the top edge of the
paper and one inch right of the left edge of the paper as the
origin of its coordinate system, and all the marks on the paper
are positioned relative to that point.  You'll have to read
{\it \TeX: The Program\/} (Volume B of the Computers \& Typesetting
series) for an explanation of why it's done
that way (or do what I'm doing: wait for the movie).  At any rate,
\LaTeX's margin parameters are {\em really\/} measuring relative
to \TeX's origin point, not the corner of the paper.  For that reason
I used that point as the upper left corner of the ``virtual'' page
area (to which the larger actual paper will be trimmed when the
book is bound), and that's why this document speaks of \verb"\topmargin",
\verb"\evensidemargin", and \verb"\oddsidemargin" as specifying the
actual margins (relative to the trimmed page area) rather than
``one inch less than'' the actual margins.

Incidentally, suppose you're working with a document design
that calls for pages a bit wider than $7\frac12{\rm in}$ or taller
than $10{\rm in}$, and you want to proof the document on
$8\frac12{\rm in}\times11{\rm in}$ paper.  Does the fact that
\TeX's origin is set down and in by one inch make this impossible?
No!  Should you use negative values of \verb"\topmargin",
\verb"\evensidemargin", and \verb"\oddsidemargin" to move the text
farther up and to the left than it would ordinarily go?  Well,
you can, but you will get very confusing results---for example,
a negative \verb"\topmargin" will cause the running head to overstrike
the tag line that \verb"pageframe" puts across the top of the sheet.
Mind you, \verb"pageframe" doesn't complain or malfunction; it just
does what you told it to do.  Still, to obtain useful results, you should
always use positive values for the margin parameters.  How can you
fit a wide or tall page onto the paper, then?  You can use a feature
of \TeX\ that (regrettably) isn't documented in the \LaTeX\ manual:
\verb"\hoffset" and \verb"\voffset".  These parameters tell \TeX\ to
displace its origin horizontally or vertically (respectively) from
its usual $(1{\rm in},1{\rm in})$ position.  They both normally have the
value 0pt, but if you put
\begin{center}
\begin{tabular}{l}
\verb"\hoffset -0.5in"\\
\verb"\voffset -0.25in"
\end{tabular}
\end{center}
(for example)
into the preamble of your document, then every mark on every page will
be shifted a quarter inch up and a half inch to the left of where it
would have been.  Using the \verb"\hoffset" and \verb"\voffset" parameters
makes a single adjustment in the \verb"dvi" file, so it affects all
marks the same way (including those made by \verb"pageframe"), and they
all maintain their relative positions to one another.  Of course, if you
move the origin up too far (more than about half an inch), then the
tag line across the top of the sheet will fall off the top edge of the
paper; your device driver may or may not accept this gracefully.
On the other hand, if you are printing the document directly (rather
than printing a camera-ready repro from which to make a printing
plate), you might want to move the origin up one inch and left one
inch; that way the upper left corner of the virtual page will coincide
with the physical upper left corner of the paper and you'll only have
to trim the sheets on two sides instead of four.

One last caveat: the \verb"pageframe" style option does its work by
substituting new code for a part of \LaTeX's output routine
(specifically, the \verb"\@outputpage" subroutine).
This means that any other document style option that also attempts
to hook into or replace this part of the output routine will
be incompatible
with the \verb"pageframe" option.  It isn't very common for style
files to do this, but it does happen.

\section{Summary}
This section summarizes the user commands provided by the
\verb"pageframe" style option.  The code for \verb"pageframe"
also defines some ``private'' control sequences that are not intended
to be used directly; all such control sequences have \verb"@" signs
in their names.

\begin{cmdlist}
%
\item[\tt\bslash paperheight]
The command \verb"\paperheight{HT}" (where \verb"HT"
is a \TeX\ dimension specification) tells the \verb"pageframe"
code that the trimmed height of the paper on which your document
will ultimately appear is \verb"HT".  This is used to determine
how far down the page the bottom corner marks are positioned.
This should be specified in the preamble of your document
(after the \verb"\documentstyle" command and before the
\verb"\begin{document}" command).  If you forget to declare
a paper height, the bottom corner marks will be positioned parallel
with the bottom of the footer.
%
\item[\tt\strut\vtop to 0pt{%
\hbox{\bslash pageframetrue}%
\hbox{\bslash pageframefalse}%
\vss}]
The conditional \verb"\ifpageframe" is used
in the code for \verb"pageframe" to control the printing of the
rectangle that outlines the trim edges of the paper.
It is true by default (so the rectangle is printed);
you will want to turn it off before printing a final copy
of your document.
%
\item[\tt\strut\vtop to 0pt{%
\hbox{\bslash innerskeltrue}%
\hbox{\bslash innerskelfalse}%
\vss}]
The conditional \verb"\ifinnerskel" is used
to control the printing of the
rectangle around the text area and the rules that
outline the header and footer.
It is false by default (so the inner skeleton is not printed).
Turning off the inner skeleton also disables the text grid feature.
%
\item[\tt\strut\vtop to 0pt{%
\hbox{\bslash textgridtrue}%
\hbox{\bslash textgridfalse}%
\vss}]
The conditional \verb"\iftextgrid" is used, together with the
\verb"\ifinnerskel" conditional,
to control the printing of a grid over the main text area of the
page.  It is true by default; however, this is not sufficient to
cause the text grid to appear.
If the inner skeleton is turned off, the text grid is not printed,
regardless of the setting of the \verb"textgrid" switch.  The text
grid is only printed if the \verb"innerskel" and \verb"textgrid"
switches are both on.  The default grid is made up of squares 10pt
on a side; it can be reset with the \verb"\gridsize" command.
%
\item[\tt\bslash gridsize]
The command \verb"\gridsize{WD}{HT}" (where \verb"WD" and \verb"HT"
are \TeX\ dimension specifications) causes the text grid to be drawn
with vertical rules separated by \verb"WD" and horizontal rules
separated by \verb"HT" (so the grid cells are rectangles of dimensions
${\tt WD}\times{\tt HT}$).
%
\item[\tt\bslash pffont]
The command \verb"\pffont{FONTSPEC}" causes the tag line across
the top of each page to be printed in the font specified by
the \verb"FONTSPEC", which should be a font designation such as
\verb"cmr10" or {\tt times at 12pt} or {\tt cmbx10 scaled
\bslash magstep2}.

\section{Acknowledgements}
The author of the \verb"pageframe" document style option is
very grateful for the assistance of Irma Tani, who beta tested
both the \TeX\ code and the documentation and suggested many
improvements in both.  Having professional experience
in book production (which the author completely lacks), she was able
to say what features would be useful in real applications.
Brian Junker also made very helpful comments about the beta
version of the documentation.

\section{Feedback}
The author of the \verb"pageframe" document style option
used it for over a year in both large and
small documents before releasing it for beta testing, and the code
went through several conceptual overhauls during that time.
He now believes it to be, not perfect, but complete enough and
clean enough to be widely useful.
Even so, he realizes that errors and pitfalls may remain, and
he would be grateful to receive reports of them, whether they
represent coding gaffes that cause malfunctions, or infelicities
of design that make \verb"pageframe" hard to use.  His name is Cameron
Smith, and he can be reached through electronic mail
as \verb"cameron@midd.cc.middlebury.edu"
or \verb"cameron@symcom.math.uiuc.edu", or by telephone
at (513) 429-2707.
