# How to create a tex file in which reflections of the top will be in the bottom of the same page?

I want to prepare a .tex document using TeXStudio satisfying the following:

• Take an A4 size paper.

• What ever is written in the top half of the page.

• Same writing will be reflected on the bottom half of the page.

• Whether I read from top or bottom it is the same, i.e., same margin (top,bottom), indent etc.

• Like the following example below.

• Use a \savebox, minipage and \rotatebox (from the graphicx package). Stick a \vfill in between the top and bottom \usebox. If you want text to flow across pages, that will be much more difficult. – John Kormylo Sep 30 '15 at 4:10
• Or you can do it in two steps. Create a half page document (literally) then use pdfpages or \includegrahics to copy these pages into a new document. – John Kormylo Sep 30 '15 at 4:14
• Your first comment is not clear to me, Please give a minimal example. – Litun John Sep 30 '15 at 5:59
• Second one is okay. But every time I write any thing I have to take the half page and include it as a figure file, which is not a good idea. Is there any other way to do this? In my example even though I have presented boxed material, but my intention was for all (documents as well as figures). For Example In case of Exam class I want my questions reflected as above in a page, so that I can save paper. – Litun John Sep 30 '15 at 6:19
• I think @JohnKormylo's 2nd solution is the best easy one. you need 2 files .tex let say source.tex and final.tex you don't need to change any thing in final.tex you just use it to produce your final output. – touhami Sep 30 '15 at 8:13

Package atbegshi captures the output box before it is shipped out. This can be used to place a rotated copy of the page on the output page:

\documentclass{article}

\usepackage[a4paper, margin=15mm]{geometry}

\usepackage{graphicx}
\usepackage{picture}
\usepackage{atbegshi}
\AtBeginShipoutInit
\AtBeginShipout{%
\AtBeginShipoutUpperLeft{%
\put(\paperwidth, -.5\paperheight){%
\rotatebox{180}{%
\smash{\hbox to 0pt{\kern1in\copy\AtBeginShipoutBox\hss}}%
}%
}%
}%
}

\usepackage{blindtext}

\begin{document}
\blinddocument
\end{document}


First two pages:

• This is the code I was searching for. – Litun John Sep 30 '15 at 11:48

THis the source.tex

\documentclass{article}
\usepackage[a5paper,landscape]{geometry}

\usepackage{blindtext}% just for dummy example
\begin{document}
\blinddocument
\end{document}


and this is your final.tex produce the output you dont need to change it every time.

\documentclass{article}
\usepackage[a4paper,scale=1]{geometry}
\usepackage{graphicx}
\newcounter{mtpage}

\setlength{\parindent}{0pt}
\begin{document}
\loop
\stepcounter{mtpage}
\includegraphics[scale=.99,page=\value{mtpage}]{doc1.pdf}
\vfill\includegraphics[scale=.99,angle=180,page=\value{mtpage}]{doc1.pdf}
\newpage
\ifnum\value{mtpage}<\pdflastximagepages
\repeat
\end{document}


• Is there any alternative to this method. Is it possible to get the required result from your Source.tex file, with out using any other .tex file (final.tex). – Litun John Sep 30 '15 at 9:37
