% \section{Introduction}
%
% This \LaTeX\ package makes it possible to typeset a document
% horizontally flipping its pages. This is sometimes required by
% publishers who want ``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 pdf\LaTeX\ 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}\DescribeMacro{\UnFlipPDF}
% The |\FlipPDF| command lets one switch on page flipping. Conversely,
% |\UnFlipPDF| switches off page flipping.
%
% \StopEventually {}
%
% \section{Implementation}
%
% Announce the name and version of the package, which requires
% \LaTeXe (actually pdfLaTeX).
% \begin{macrocode}
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{flippdf}%
[2006/06/30 1.0 Horizontal flipping of pages with pdfLaTeX]
% \end{macrocode}
%
% Reminds the dependence on \Lpack{everypage}.
% \begin{macrocode}
\RequirePackage{everypage}
% \end{macrocode}
% \begin{macro}{\if@sc@flippdf}
%
% Defines 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}
\endinput
