This is sometimes required by publishers who use % photographic printing process that need ``camera-ready'' documents to be % printable on transparent films, so that one reads the pages correctly by % looking \emph{through} the film (i.e., with the \emph{unprinted} side of % the film towards his eyes). % % It is also possible to activate the mirroring capability on a page % by page basis. % % This package requires \Lpack{everypage} by the same author and works % with \hologo{pdfLaTeX} only. % % \section{User interface} % By default, once loaded as: % \begin{quote} % |\usepackage{pdfflip}| % \end{quote} % the \Lpack{pdfflip} becomes immediately \emph{active} (i.e., starts % flipping horizontally every page). Conversely, by selecting the % \Lopt{off} option as in % \begin{quote} % |\usepackage[off]{pdfflip}| % \end{quote} % The package is loaded but remains inactive. % % \DescribeMacro{\FlipPDF} The |\FlipPDF| command lets one switch on page % flipping. Conversely, \DescribeMacro{\UnFlipPDF}|\UnFlipPDF| switches % off page flipping. % % % \section{Examples} % \subsection{Plain case} % In this example, every page of the document is flipped, relying on the % automatic operation mode of the package. % \iffalse %<*test-1> % \fi % \begin{macrocode} \documentclass[a4paper]{article} \usepackage{flippdf} \usepackage{lipsum} \title{Test document for the flippdf package} \begin{document} \maketitle \lipsum[1-5] \end{document} % \end{macrocode} % \iffalse % % \fi % % \subsection{Case with activation and deactivation} % In this example, the page flipping is manually activated and deactivated. % \iffalse %<*test-2> % \fi % \begin{macrocode} \documentclass[a4paper]{article} \usepackage[off]{flippdf} \usepackage{lipsum} \title{Test document for the flippdf package} \begin{document} \thispagestyle{empty} {\Large Some non-mirrored initial info} \bigskip \lipsum[1] \maketitle \setcounter{page}{1} \FlipPDF \lipsum[2-6] \clearpage \UnFlipPDF \thispagestyle{empty} {\Large Some non-mirrored final info} \bigskip \lipsum[7] \end{document} % \end{macrocode} % \iffalse % % \fi % % \StopEventually {} % % \section{Implementation} % % \iffalse %<*flippdf> % \fi % Announce the name and version of the package, that requires % \hologo{LaTeX2e} (actually \hologo{pdfLaTeX}). % \changes{R1.0b}{2020/10/11}{% % Require \Lpack{everypage} package to be at least at its 2007/06/20 (R1.1) % release.} % \begin{macrocode} \NeedsTeXFormat{LaTeX2e} \ProvidesPackage{flippdf}% [2020/10/11 1.0b Horizontal flipping of pages with pdfLaTeX] % \end{macrocode} % % Assure that the dependence on \Lpack{everypage} is satisfied. % \begin{macrocode} \RequirePackage{everypage}[2007/06/20] % \end{macrocode} % \begin{macro}{\if@sc@flippdf} % % Define a boolean variable to remember if pages are to be flipped or % not. % \begin{macrocode} \newif\if@sc@flippdf % \end{macrocode} % \end{macro} % % \begin{macro}{\FlipPDF}\begin{macro}{\UnFlipPDF} % Define the commands used to switch on and off the horizontal % flipping of the document pages. % \begin{macrocode} \newcommand\FlipPDF{\@sc@flippdftrue} \newcommand\UnFlipPDF{\@sc@flippdffalse} % \end{macrocode} % \end{macro}\end{macro} % % By default activate the flipping: % \begin{macrocode} \FlipPDF % \end{macrocode} % % Set up the processing of options: % \begin{macrocode} \DeclareOption{off}{\UnFlipPDF} \ProcessOptions % \end{macrocode} % % And eventually, tell \LaTeX\ to flip every page, by using the % \Lpack{everypage} hook: % \begin{macrocode} \AddEverypageHook{% \if@sc@flippdf \pdfliteral direct {-1 0 0 1 \strip@pt\paperwidth\space 0 cm} \fi} % \end{macrocode} % \iffalse % % \fi % % \Finale % \PrintChanges % \PrintIndex % % \CharacterTable % {Upper-case \A\B\C\D\E\F\G\H\I\J\K\L\M\N\O\P\Q\R\S\T\U\V\W\X\Y\Z % Lower-case \a\b\c\d\e\f\g\h\i\j\k\l\m\n\o\p\q\r\s\t\u\v\w\x\y\z % Digits \0\1\2\3\4\5\6\7\8\9 % Exclamation \!
