Question

How do I align an image to center?

In a beamer presentation I have a 2-3 items on a slide followed by an image. The image is not wide enough to cover whole slide, so it leaves around 30% space from right. How do I adjust it to leave enough space on both sides?

\begin{frame}
\frametitle{Outlook}
\begin{itemize}
\item apps
\item apps
\item apps
\includegraphics[scale=0.3]{P2P}    
\end{itemize}
\end{frame}

Answer 1

It is enough to use the center enviroment:

\begin{center}
    \includegraphics{yourimage}
\end{center}

Answer 2

The third way is to use the figure environment, which is the best way in my opinion, since it provides the right mark-up. (beamer centers the figures by default.)

\begin{figure}
   \includegraphics{<your image>}
\end{figure}

In this case on may also add a caption with \caption{<text>}

Answer 3

You could also do something like this:

\begin{figure}[!h]
    \caption{My caption}
    \centering
    \includegraphics[width=50mm]{theImage}
    \label{fig:label}
\end{figure}

Answer 4

Here are two ways of achieving this:

\begin{center}
  \includegraphics{<your image>}
\end{center}

or

\hfill\includegraphics{<your image>}\hspace*{\fill}

The former may add some vertical whitespace, while the latter centers its contents on the line used.

Answer 5

One simple way to center an image is to use the adjustbox package with the export option. It provides the center=<width> key to \includegraphics, which centers the image around the given width. It defaults to the \linewidth, so use:

\usepackage[export]{adjustbox}
% ....

\includegraphics[scale=0.3,center]{P2P} 

Inside a itemize this will center the image relative to the itemize text width, not to the frame.

Answer 6

\centering\includegraphics{...} — when the figure is smaller than the text width \centerline{\includegraphics{...}} — when the figure is wider than the text width

Answer 7

This helps me

\begin{figure}[!h]
\includegraphics[width= 365pt]{./figures/xyz.png}
\centering
\caption{The picture shows xyz architecture}
\label{fig:xyz}
\end{figure}

You can of course change the width and other things as per your case. The only major part is \centering which helps here.

Answer 8

I always use:

\begin{center}
  \includegraphics[width=\textwidth]{image}
\end{center}

That's almost perfect for raw screenshots, as images will not overflow the visible content.

Answer 9

You can also use tikz.

\begin{tikzpicture}[remember picture,overlay]
   \node at (current page.center) node[anchor=center]{\includegraphics{}};
\end{tikzpicture}

will place your image on the center of the page. This does not account for any header, however. If you have a header that is 1 cm tall you can move the picture to compensate thus:

\begin{tikzpicture}[remember picture,overlay]
   \node at ($(current page.center) +(0,-1cm)$) node[anchor=center]{\includegraphics{}};
\end{tikzpicture}

You can also anchor the node to any corner of side of the page, thus achieving absolute positioning with complete control rather effectively.

(I realize this question is old, but the solution is versatile and offers excellent positioning control)
