This is an example of what i want to create

I have three images, I want to organize them in a frame to cause the effect of a zoom, similar to the image I have posted above. In this image the galaxy is at left, but i want to learn how to modified this position in the code, becouse acctually I need the second image(in our case, the Solar System) at right.

It is no necessarily that one image overlap the other, but it is not a problem if this occurs

I have no clue how to do it, any advice?

  • what's the format of the images? Just bitmaps or tikz/ps? Do you have them as separate files? – Bordaigorl Nov 30 '14 at 20:42
  • @Bordaigorl I have them in separate files in png format. – JuanMuñoz Nov 30 '14 at 21:58

    So basically you need to overlay several different images. \raisebox, \llap and \rlap can be used to overlay things, but the most elegant solution would be to use tikz to overlay nodes containing \includegraphics. – John Kormylo Nov 30 '14 at 22:41

Here is a simple version based on John Kormylo's comment and Caramdir's answer. (Some explanation in my answer to another question.) Background image courtesy of NASA.

\documentclass[border=10pt,tikz]{standalone}

\begin{document}

  \begin{tikzpicture}
    \node (nasa) [anchor=south west, inner sep=0pt, outer sep=0pt] at (0,0) {\includegraphics[scale=.25]{pia17172}};
%   \draw [help lines] (nasa.south west) grid (nasa.north east);% for placing help with specifying locations
    \begin{scope}[x=(nasa.south east), y=(nasa.north west)]
      \node [pin={[pin distance=300, pin edge={thick, white}]-5:{\includegraphics[scale=.2]{tiger}}}] at (.615,.275) {};
      \node [font=\Huge\bfseries, text=white, anchor=south west] {Credit: NASA};
    \end{scope}
  \end{tikzpicture}

\end{document}
