I'm preparing a beamer presentation and have a complicated mindmap in it. To make it nicely fit on the frames I use \tikzset{small mindmap}.

On subsequent frames I have images with nicely drawn scale bars.

Setting a 'small mindmap' messes up the placement of my scalebar label, as can be seen in the screenshot below.

messed up background

I think it has something to do with setting a general zoom/scale factor in tikz. Is there a way I can 'reset' tikz to a normal state after drawing my mindmap? This would result in (something like) the second screenshot.

intended result

Below is the code, boiled down to nearly minimal state. I couldn't manage to find an example image, is this not available in beamer? The issue can be seen when commenting/uncommenting line 12 and recompiling the document.



\newlength\imagewidth% needed for scalebars
\newlength\imagescale% needed for scalebars


\tikzset{small mindmap}

        \path[mindmap] node[concept] {Something} child {node[concept] {A}};

    \def\x{949}% scalebar-x starting at golden ratio of image width of 1536px = 949
    \def\y{1335}% scalebar-y at 90% of image height of 1483px = 1335
        \node[anchor=north west, inner sep=0pt, outer sep=0pt] at (0,0) {\includegraphics[width=\imagewidth]{example−image}};
        \draw[|-|,blue,thick] (0,742) -- (1536,742) node [sloped,midway,above,fill=green,semitransparent,text opacity=1] {1536px};

    Call \tikzset{small mindmap} in your first tikzpicture... Jun 21 at 14:33

    Note: example−image is not example-image ( is not -). Jun 21 at 14:47
  • @PaulGaborit: Comment1: Thanks for the pointer, this helps. I'll move all the settings changes into the tikzpictures. Comment2: I copy-pasted from texdoc mwe and the dashes were not copied correctly.
