# Positioning and opacity

I'm trying to include an image to my beamer using Tikz. The problem is that I don't find the code to position the image horizontally and vertically as well as being able to change its opacity.

\usepackage{tikz}
\usetikzlibrary{calc}
\begin{frame}{Outline}
\begin{picture}(0,0)
\put(200,-200){\includegraphics[opacity=0,5][height=12cm]{Images/image.png}}
\end{picture}
\end{frame}

• Welcome to TeX.se. You haven't given us very much information to be able to help you. Can you edit your question to show a minimal compilable document that shows what you are trying to do? Are you using beamer? Is the image supposed to be a background image for all your slides? On positioning, see e.g. Beamer background image centered On setting opacity for an included image see Includegraphics: set image opacity. – Alan Munn Mar 3 at 22:21

Welcome to TeX-SE! Thanks for adding some code. Given that you load tikz and the calc library, I'd like to suggest

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
\begin{frame}
\frametitle{Outline}
\begin{tikzpicture}[overlay,remember picture]
\node[opacity=0.5] at ($(current page.center)+(1,1)$)
{\includegraphics[height=2cm]{example-image-duck}};
\end{tikzpicture}
\end{frame}
\end{document}


With overlay,remember picture you can access and use absolute page coordinates, and with calc you can add coordinates, as illustrated.
