When generating DVI output, users should +% note that rotation is typically \emph{not} visible in a DVI viewer: +% conversion to, and viewing, PostScript or PDF is necessary. +% +% \section{Usage} +% +% \subsection{Package options} +% +% Sideways figures and tables always take up the whole page. In +% single-sided documents, they may be rotated so that the bottom of +% the figures is on the left (package option +% `\texttt{counterclockwise}') or the right (package option +% `\texttt{clockwise}'). The default is to turn so that the bottom is +% on the right (option `\texttt{clockwise}'). +% +% Option `\texttt{anticlockwise}' is an alias for +% `\texttt{counterclockwise}'. +% +% If the `\texttt{twoside}' option has been given to the main document +% class (either explicitly, or implicitly as in the default for book +% class), the package will rotate sideways figures according to the +% page number (this requires at least two passes through \LaTeX{}). +% If you want the `\texttt{twoside}' option, but want the figures +% always in one direction, use the `\texttt{figuresright}' or +% `\texttt{figuresleft}' options to the package. +% +% The package can produce a lot of logging information; the +% amount of information is controlled by the package options +% `\texttt{quiet}' (fewest messages; default), `\texttt{log}' and +% `\texttt{chatter}' (most messages). +% +% All other options are passed to the \textsf{graphicx} package when +% it is loaded to provide rotation functions. +% +% \subsection{Float environments} +% +% The environments \texttt{sidewaystable} and \texttt{sidewaysfigure} +% introduce landscape-form floating tables and figures, respectively. +% (Each of the environments has a ``starred'' version, such as +% \texttt{sidewaystable*}, for a single-column float in a double-column +% area of the document.) +% +% New rotated environments may be declared using the combined +% facilities of the float and rotfloat packages. +% +% \subsection{Other environments and commands} +% The package provides other \LaTeX\ environments: +% \begin{description} +% \item[\mdseries\ttfamily sideways] prints the contents of the +% environment turned through 90 degrees counterclockwise; +% \item[\mdseries\ttfamily turn] prints the contents turned through an +% arbitrary angle (the argument to the environment); +% \item[\mdseries\ttfamily rotate] prints the contents turned through +% an arbitrary angle but does \emph{not} leave any space for the result +% \end{description} +% +% The command \cs{turnbox}\marg{angle}\marg{matter to turn} is a macro +% version of the \texttt{rotate} environment. +% +% A set of examples is given in the file \texttt{examples.tex} +% +% \subsection{Positioning} +% +% Floats appear one to a page, and are positioned by spacer skips that +% appear (logically) above and below the floating object. The skips, +% \cs{rotFPtop} and \cs{rotFPbot}, are initialised from the standard +% \LaTeX{} (internal) \cs{@fptop} and \cs{@fpbot} skips. As a result, +% by default, rotated floats appear horizontally centred on their +% float pages. +% +% Some sensible values for the registers are: +% \par\noindent +% \begin{tabular}{@{}llp{3in}@{}} +% \cs{rotFPtop} & \cs{rotFPbot} & Effect \\ +% \hline +% 0pt plus 1fil & 0pt plus 1fil & figure/table appears in middle +% (default value) \\ +% 0pt & 0pt plus 1fil & figure/table appears with its top +% nearest the edge of the page \\ +% 0pt plus 1fil & 0pt plus 2fil & figure/table's bottom appears +% twice as far from the edge as the +% top does +% \end{tabular} +% +% \StopEventually{} +% +% \section{Setup} +% Now we present the documented code.

These are `fixed' +% environments that just do 90 degree rotation, but it would be easy +% to parameterize this to do other rotations if needed (the mind +% boggles\ldots) +% +% \begin{macro}{\@rotfloat} +% \begin{macro}{\@xrotfloat} +% \begin{macro}{\rot@float@box} +% First a generalised `rotfloat' environment. We need to intercept +% \LaTeX's float macros, in order to change the assumed width of a +% float being |\columnwidth|. We want it to work on a width of +% |\textheight| so that when we rotate the float, it comes out +% the right height. This is not actually very satisfactory, since what +% we \emph{really} want is for rotated floats to occupy the space they +% actually \emph{use}. The captions are a problem --- since they can +% precede the figure or table, we cannot set them in a box of the +% right width (ie the \emph{height} of the forthcoming object), because +% it has not happened yet. The result of these difficulties is that +% rotated figures always end up as full page figures. +% \begin{macrocode} +\newsavebox\rot@float@box +\def\@rotfloat#1{% + \@ifnextchar[% + {\@xrotfloat{#1}}% + {\edef\@tempa{\noexpand\@xrotfloat{#1}[\csname fps@#1\endcsname]}\@tempa}% +} +\def\@xrotfloat#1[#2]{% + \@float{#1}[#2]% +% \end{macrocode} +% Set the float contents in +% a box of width \cs{textheight} instead of \cs{columnwidth}. +% \begin{macrocode} + \begin{lrbox}\rot@float@box + \begin{minipage}\textheight + } +% \end{macrocode} +% \end{macro} +% \end{macro} +% \end{macro} +% +% \begin{macro}{\end@rotfloat} +% We call \LaTeX's \cs{end@float} macro having previously rotated +% the box \cs{@currbox}. +% The rotation is either clockwise or +% anti-clockwise, depending on whether the page is odd or even; +% in oneside mode it is always odd. +% \begin{macrocode} +\def\end@rotfloat{% +% \end{macrocode} +% If we are going to know whether pages are odd or even, +% we need to use the a variant \cs{pageref} mechanism and our own +% specialised labels. +% \begin{macrocode} + \end{minipage}\end{lrbox}% + \stepcounter{r@tfl@t}% + \rot@label{RF\ther@tfl@t}% + \rot@pageref{RF\ther@tfl@t}{\R@@page}% + \edef\@tempa{Adding sideways \@captype\space on page \R@@page\space} + \rot@mess@toks\expandafter{\@tempa} + \wd\rot@float@box\z@ + \ht\rot@float@box\z@ + \dp\rot@float@box\z@ + \vbox to \textheight{% +% \end{macrocode} +% We need to know for sure which direction rotation is going to +% be in, so locally reset the graphics units. +% \begin{macrocode} + \setkeys{Grot}{units=360}% + \if@rot@twoside + \else + \let\R@@page\rot@LR + \fi + \ifthenelse{\isodd{\R@@page}}{% + \if@rot@twoside + \rot@mess@toks\expandafter{\the\rot@mess@toks (right hand page)}% + \fi + \vfill + \@@line{% + \hskip\rotFPtop + \rotatebox{90}{\box\rot@float@box}% + \hskip\rotFPbot + }% + }{% + \if@rot@twoside + \rot@mess@toks\expandafter{\the\rot@mess@toks (left hand page)}% + \fi + \@@line{% + \hskip\rotFPbot + \rotatebox{-90}{\box\rot@float@box}% + \hskip\rotFPtop + }% + \vfill + }% + \rot@message{\the\rot@mess@toks} + }% + \end@float +} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\sidewaysfigure} +% \begin{macro}{\endsidewaysfigure} +% \begin{macro}{\sidewaystable} +% \begin{macro}{\endsidewaystable} +% The following definitions set up two environments, +% \texttt{sidewaystable} and \texttt{sidewaysfigure}, which uses this +% type of float.
