% \section{Introduction}
%
%    This \LaTeXe\ package is a reimplementation of \file{layout.sty}
%    by Kent McPherson. It defines the command |\layout| which
%    produces an overview of the layout of the current document.
%
% \StopEventually{}
%
%    This package has an option \Lopt{verbose}. Using it will make the
%    command |\layout| type some of the parameters on the terminal.
%    \begin{macrocode}
%<*package>
\DeclareOption{verbose}{\let\type\typeout}
\DeclareOption{silent}{\let\type\@gobble}
%    \end{macrocode}
%    The default mode is \Lopt{silent}.
%    \begin{macrocode}
\ExecuteOptions{silent}
\ProcessOptions
%    \end{macrocode}
%
% \begin{macro}{\bs}
%    Define |\bs| if it is undefined, redefine it if it is already
%    defined.
%    \begin{macrocode}
\@ifundefined{bs}{\newcommand\bs{\char '134 }}%
  {\renewcommand\bs{\char '134 }}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\ConvertToCount}
%    This macro stores the value of a \emph{length} register in a
%    \emph{count} register.
%    \begin{macrocode}
\def\ConvertToCount#1#2{%
%    \end{macrocode}
%    First copy the value
%    \begin{macrocode}
  #1=#2
%    \end{macrocode}
%    Then divide it by 65536.
%    \begin{macrocode}
  \divide #1 by 65536}
%    \end{macrocode}
%    The result of this is that the \emph{count} register holds the
%    value of the \emph{length} register in points.
% \end{macro}
%
% \begin{macro}{\SetToHalf}
% \begin{macro}{\SetToQuart}
%    Small macros used in computing positions.
%    \begin{macrocode}
\def\SetToHalf#1#2{#1=#2\relax\divide#1by\tw@}
\def\SetToQuart#1#2{#1=#2\relax\divide#1by4}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\Identify}
%    A small macro used in identifying dimensions.
%    \begin{macrocode}
\def\Identify#1{%
  \put(\PositionX,\PositionY){\circle{20}}
  \put(\PositionX,\PositionY){\makebox(0,0){\tiny #1}}
}
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\InsideHArrow}
%    This macro is used to produce two horizontal arrows inside a box.
%    The argument gives the width of the box.
%    \begin{macrocode}
\def\InsideHArrow#1{{%
  \ArrowLength = #1
  \divide\ArrowLength by \tw@
  \advance\ArrowLength by -10
  \advance\PositionX by -10
  \put(\PositionX,\PositionY){\vector(-1,0){\ArrowLength}}
  \advance\PositionX by 20
  \put(\PositionX,\PositionY){\vector(+1,0){\ArrowLength}}
}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\InsideVArrow}
%    This macro is used to produce two vertical arrows inside a box.
%    The argument gives the height of the box.
%    \begin{macrocode}
\def\InsideVArrow#1{{%
  \ArrowLength = #1
  \divide\ArrowLength by \tw@
  \advance\ArrowLength by -10
  \advance\PositionY by -10
  \put(\PositionX,\PositionY){\vector(0,-1){\ArrowLength}}
  \advance\PositionY by 20
  \put(\PositionX,\PositionY){\vector(0,+1){\ArrowLength}}
}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\OutsideHArrow}
%    This macro is used to produce two horizontal arrows to delimit a
%    length. The first argument is the position for the right arrow,
%    the second argument gives the length and the third specifies the
%    length of the arrows.
%    \begin{macrocode}
\def\OutsideHArrow#1#2#3{{%
  \PositionX = #1
  \advance\PositionX by #3
  \put(\PositionX,\PositionY){\vector(-1,0){#3}}
  \PositionX = #1 \advance\PositionX-#2
  \advance\PositionX by -#3
  \put(\PositionX,\PositionY){\vector(+1,0){#3}}
}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\OutsideVArrow}
%    This macro is used to produce two vertical arrows to delimit a
%    length. The first argument is the position for the lower arrow,
%    the second argument gives the length and the third and fourth
%    specify the lenghts of the lower and upper arrow.
%    \begin{macrocode}
\def\OutsideVArrow#1#2#3#4{{%
  \PositionY = #1
  \advance\PositionY by -#3
  \put(\PositionX,\PositionY){\vector(0,+1){#3}}
  \PositionY = #1
  \advance\PositionY#2
  \advance\PositionY#4
  \put(\PositionX,\PositionY){\vector(0,-1){#4}}
}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\Show}
%    Macro used in the table that shows the setting of the parameters.
%    \begin{macrocode}
\def\Show#1#2{\bs #2 = \expandafter\number\csname #1@#2\endcsname pt}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\Type}
%    Macro used to show a setting of a parameter on the terminal.
%    \begin{macrocode}
\def\Type#1#2{%
  \type{#2 = \expandafter\number\csname #1@#2\endcsname pt}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\oneinch}
%    A constant, giving the length of an inch in points (approximately)
%    \begin{macrocode}
\newcount\oneinch
\oneinch=72
%    \end{macrocode}
% \end{macro}
%
%    Because the overview of the layout is produced in a figure
%    environment we need to allocate a number of counters that are
%    used to store the values of various dimensions.
%
%    The dimensions of the paper
%    \begin{macrocode}
\newcount\cnt@paperwidth
\newcount\cnt@paperheight
\ConvertToCount\cnt@paperwidth\paperwidth
\ConvertToCount\cnt@paperheight\paperheight
%    \end{macrocode}
%
%    the offsets,
%    \begin{macrocode}
\newcount\cnt@hoffset
\newcount\cnt@voffset
\ConvertToCount\cnt@hoffset\hoffset
\ConvertToCount\cnt@voffset\voffset
%    \end{macrocode}
%
%    dimensions of the text area,

%    \end{macrocode}
%
%    dimensions of the running heads,
%    \begin{macrocode}
\newcount\cnt@headheight
\newcount\cnt@headsep
\ConvertToCount\cnt@headheight\headheight
\ConvertToCount\cnt@headsep\headsep
%    \end{macrocode}
%
%    marginal paragraphs,
%    \begin{macrocode}
\newcount\cnt@marginparsep
\newcount\cnt@marginparwidth
\newcount\cnt@marginparpush
\ConvertToCount\cnt@marginparsep\marginparsep
\ConvertToCount\cnt@marginparwidth\marginparwidth
\ConvertToCount\cnt@marginparpush\marginparpush
%    \end{macrocode}
%
%    the distance between the running footers and the text,
%    \begin{macrocode}
\newcount\cnt@footskip
\ConvertToCount\cnt@footskip\footskip
%    \end{macrocode}
%    and the height of the footers, which is needed here to display a
%    box, but which isn't used by \LaTeX.
%    \begin{macrocode}
\newcount\fheight
\fheight=12
%    \end{macrocode}
%
%    Apart from integer representations of the page layout parameters
%    we also need registers to store reference values in.
%
%    The position of the top of the `printable area' is
%    one inch below the top of the paper by default. The value of
%    |\ref@top| is relative to the lower left corner of the picture
%    environment that will be used.
%
%    \begin{macrocode}
\newcount\ref@top
\ref@top=\cnt@paperheight \advance\ref@top by -\oneinch
%    \end{macrocode}
%
%    For the offsets,
%    \begin{macrocode}
\newcount\ref@hoffset
\newcount\ref@voffset
%    \end{macrocode}
%    The |\hoffset| and |\voffset| values are added to the default
%    offset of one inch.
%    \begin{macrocode}
\ref@hoffset=\cnt@hoffset  \advance\cnt@hoffset by \oneinch
\ref@voffset=\cnt@voffset  
%    \end{macrocode}
%
%    |\cnt@voffset| is converted to be relative to the origin of the
%    picture. 
%    \begin{macrocode}
\cnt@voffset=\ref@top 
\advance\cnt@voffset by -\ref@voffset
%    \end{macrocode}
%
%    and the text areas, running heads,
%    \begin{macrocode}
\newcount\ref@head
\ref@head=\ref@top
  \advance\ref@head by -\ref@voffset
  \advance\ref@head by -\cnt@topmargin  
  \advance\ref@head by -\cnt@headheight
%    \end{macrocode}
%
%    body of the text
%    \begin{macrocode}
\newcount\ref@body
\ref@body=\ref@head  
  \advance\ref@body by -\cnt@headsep   
  \advance\ref@body by -\cnt@textheight
%    \end{macrocode}
%
%    and running footers.
%    \begin{macrocode}
\newcount\ref@foot
  \ref@foot=\ref@body
  \advance\ref@foot by -\cnt@footskip
%    \end{macrocode}
%
%    These are different for even and odd pages, so they are computed
%    by |\layout|.
%    \begin{macrocode}
\newcount\ref@margin
\newcount\ref@marginwidth
\newcount\ref@marginpar
%    \end{macrocode}
%
%    The following are a number of scratch registers, used in the
%    positioning of the various pices of the picture..
%    \begin{macrocode}

\newcount\ExtraYPos
\newcount\PositionX
\newcount\PositionY
\newcount\ArrowLength

%  Now we begin the picture environment; dividing all the lengths by

%    Here we can end the picture environment and indsert a little

%    Below the picture we put a table to show the actual values of the

%
%    The table is typeset inside a box with a depth of 0 to always
%    keep it on the same page as the picture.
