# Controlling the exact position of objects on a page

I'm using Linux on a server (CentOS 5) to generate a one page PDF report using LaTeX. The LaTeX distribution is quite old - latex --version returns the following:

pdfeTeX 3.141592-1.21a-2.2 (Web2C 7.5.4)
kpathsea version 3.5.4

As a result, there are several packages that are not available to me (wallpaper for example). I've made a pdf file for headers and footers which I insert as figures at the top and bottom of the page, and have some images inserted in the center part of the page. Is there a way that I can specify the location of objects using co-ordinates, rather than letting LaTeX choose the positioning? For the most part my current layout is satisfactory, but I would like to make sure that my footer is locked to the bottom of the page (for example).

I'd prefer not to install a recent version of LaTeX on the server as most things are currently working but just need some fine tuning.

Place a \begin{picture}(0,0) in the header of the page so that it makes a zero-sized box at a know position, then you can \put text or graphics at exact coordinates relative to that box.

There is an example of this technique in my answer to

Just to expand on the other two answer with a small example:

\documentclass{article}
\usepackage[left=1in,right=1in]{geometry}
\usepackage{xcolor,rotating,picture,lipsum}
\makeatletter

\def\even@samplepage{%
\begin{picture}(0,0)
\put(\Xeven,\Yeven){\turnbox{90}{\Huge \textcolor{\watermark@textcolor}{\watermark@text}}}
\end{picture}
}
%% Define a macro to print SAMPLE PAGE IN THE MARGIN
\def\odd@samplepage{%
\begin{picture}(0,0)
\put(\Xodd,\Yodd){\turnbox{90}{\Huge \textcolor{\watermark@textcolor}{\watermark@text}}}
\end{picture}
}

\def\watermarktext#1{\gdef\watermark@text{\fontfamily{phv}\selectfont#1}}
\def\watermarktextcolor#1{\gdef\watermark@textcolor{#1}}
\watermarktext{PRE-PRINT}
\watermarktextcolor{purple}
\def\ps@samplepage{\let\@mkboth\@gobbletwo
%%
\def\Xodd{500}
\def\Xeven{-70}\def\Yeven{-810}
\def\Yeven{-\expandafter\strip@pt\textheight}
\let\Yodd\Yeven
\makeatother
\begin{document}
\thispagestyle{samplepage}
\lipsum
\end{document}


The important part, as the other posters mentioned is to use the picture environment.

 \def\even@samplepage{%
\begin{picture}(0,0)
\put(\Xeven,\Yeven){\turnbox{90}{\Huge \textcolor{\watermark@textcolor}   {\watermark@text}}}
\end{picture}
}


Using the textpos package:

 \documentclass{article}
\usepackage[absolute]{textpos}
\setlength{\TPHorizModule}{1mm}%
\setlength{\TPVertModule}{1mm}%
\begin{document}
\begin{textblock}{200}(50,30)%
This is a test
\end{textblock}%
\end{document}

For a simple example, if I do the following: \begin{picture}(0,0) \put(6,3){}{text} \end{picture} this does not quite work for repositioning, but it does appear on the page. How can I adjust the location? I found it a little hard to understand what all the arguments are in the above example. – celenius Mar 28 '12 at 15:24
@celenius You want the text to repeat on every page or on a specific page only? – Yiannis Lazarides Mar 28 '12 at 15:28
It's just a one page document so there is no repetition. – celenius Mar 28 '12 at 15:30
@celenius Then you better off with texpos, I will post a short example. – Yiannis Lazarides Mar 28 '12 at 15:35
great - thank you for your help! – celenius Mar 28 '12 at 15:44

The textpos package might be what you're looking for.

+1, but could you add a little document demonstrating a really basic usage case of textpos? – doncherry Mar 28 '12 at 14:39
I'm not myself a textpos user, but the documentation in the directory I linked to contains a short example and there's a larger example niepraschk-eso-pic.tex which shows the combination with eso-pic. HTH. – Stephan Lehmke Mar 28 '12 at 14:51

At http://www.texample.net/tikz/examples/exam-sheet/ there is a very nice tikz solution with working code. It allows the instructor to dogear the corner hiding the name until the grading is completed. It works well for one-page quizzes.
