[Tex/LaTex] Centering an image vertically

graphicspositioning

I'm currently having a few problems with centering an image on a page (both vertically and horizontally) while enlarging the image so that it is taking the whole width of the page.

I'm managing to center the picture horizontally, but not vertically. The code below shows the version I made that centers the image horizontally. My question is here what can I do to center it also vertically?

I'm having an srcbook class .tex:

\documentclass[11pt,a4paper,BCOR10mm,DIV11,toc=listof,parskip=full]{scrbook}

\usepackage[english]{babel}
\usepackage[utf8x]{inputenc}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{booktabs}            
\usepackage{multicol}

I'm currently positioning the image like this:

\centerline\noindent\makebox[\textwidth]{\includegraphics[width=\paperwidth]{MyImage.jpg}

Best Answer

\centerline takes an argument so in

\centerline\noindent\makebox[\textwidth]{\includegraphics[width=\paperwidth]{MyImage.jpg}

the argument is just \noindent

so it is equivalent to

\centerline{\noindent}%
\makebox[\textwidth]{\includegraphics[width=\paperwidth]{MyImage.jpg}}

so you get one blank white line from the \centerline then an overfull box with the image.

possibly you want

\vspace*{\fill}
\noindent
\hspace*{-\oddsidemargin}%
\makebox[0pt][l]{\includegraphics[width=\paperwidth]{MyImage.jpg}}
\vspace*{\fill}

I am assuming here you did intend your image to be as wide as the paper not just as wide as the text block, so covering both margins.

The multicols needs to be smaller than the outer text so it can be centered. This can be done by using the minipage environment with a smaller width then \textwidth. If it has the same width it is technically already centered when printed with justification. I'm not sure if this is what you are looking for. Using a enumeration environment with short text like in your MWE is not a good way to show that. Enumerations are differently aligned than normal text.

Here my code which includes some normal text and an enumeration. The blindtext package is used to insert some dummy text.

\documentclass{article}
\usepackage{multicol}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage[demo]{graphicx}
\begin{document}
\blindtext
\begin{center}
  \includegraphics[width=3in]{plan}
  \begin{minipage}{3in}
    \begin{multicols}{2}
        \blindtext
    \end{multicols}
  \end{minipage}
  \begin{minipage}{3in}
    \begin{multicols}{2}
        \begin{enumerate}
            \item 1
            \item 2
            \item 3
            \item 4
            \item 5
            \item 6
            \item 7
            \item 8
            \item 9
            \item 10
            \item 11
            \item 12
            \item 13
        \end{enumerate}
    \end{multicols}
  \end{minipage}
\end{center}
\blindtext
\end{document}

[Tex/LaTex] Centering an equation vertically

beamer frames are vertically centered by default unless you have \documentclass[t]{beamer} or \begin{frame}[t].
You can use \vfil and \vfill to accomplish a vertically centered equation and some text that is vertically centered between the top and the equation.

Code

\documentclass{beamer}
%\usepackage{lua-visual-debug} % used to show output debug
\begin{document}
\begin{frame}{Title}
Text over equation
\vfill
\(equatio^n\)
\vfill
\end{frame}
\end{document}

Output

output without lua-visual-debug output with lua-visual-debug

Is this what you want?
