Beamer image not centered

The following code:

\frame[plain]
{
\frametitle{}
\includegraphics[scale=0.75]{1.jpg}
}


is resulting in an image which is offset to the right. The left margin is larger than the right margin. Wrapping the \includegraphics in a figure or center environment does not solve the problem.

How can I center the image in beamer?

• Presumably the image is too wide. Check the log file (*.log) for corresponding warnings. Scale the image to text width if necessary. – Thorsten Donig Oct 30 '13 at 19:48
• Is the image wider than the text width? try [width=.75\textwidth] instead of using scale – David Carlisle Oct 30 '13 at 19:50
• @ThorstenDonig: The image is appearing on the page with space all around it. It's just that the space on the left is too large so it's not centered. – SabreWolfy Oct 30 '13 at 19:50
• @DavidCarlisle: That resulted in a right margin, which was too wide. Using [width=1\textwidth] solved this for many images. Others were solved by placing them in a centering environment and specifying the height. – SabreWolfy Oct 30 '13 at 20:23

If you insist on using scale key, then find the best value for it. Varying the value in a closed interval (as shown in the following animation) can help you find the best value for the scale key.

\documentclass{beamer}
\usepackage{graphicx,multido}
\begin{document}
\multido{\n=0.1+0.1}{15}{%
\begin{frame}{scale=\n}
\begin{center}
\includegraphics[scale=\n]{example-image-a}
\end{center}
\end{frame}}
\end{document}


• I don't insist on using scale. I just thought it was the best way. I tried a few different scale sizes and a left margin was still present in all cases. – SabreWolfy Oct 30 '13 at 19:58
• Note: Adjust the increment value (2 decimal places should be more than enough, for example \n=0.01+0.01) to get more precise scale. – kiss my armpit Oct 30 '13 at 20:06
