The question is very simple: I have TikZ pictures inside a LaTeX document and I need to determine the heights and widths of their bounding boxs to calculate the aspect ratios.
I know how to do that for pdf, eps files and whatnot in ghostscript, and one possible solution is to just compile the TikZ code for each picture as standalone and then use GS.
However, this seems neither direct nor elegant and even might give wrong values, depending on what the standalong compilation does.
So how do I get the bounding box coordinates directly?
MWE - I'd like to get the coordinates of the bounding box of Figure 1:
\documentclass[10pt,a4paper]{article}
\usepackage{tikz}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{figure}[h!]
\begin{center}
\begin{tikzpicture}
\node[draw,fill,red,circle,radius=5cm] at (0,0) {};
\draw[fill,green,] (2,0) rectangle (4,1);
\end{tikzpicture}
\end{center}
\caption{\lipsum[1][1-3]}
\end{figure}
\lipsum[1]
\end{document}

Reset to default 1You could place the tikzpicture in a box and measure the size of the box:
\documentclass[10pt,a4paper]{article}
\usepackage{tikz}
\usepackage{lipsum}
\newsavebox{\quack}
\begin{document}
\lipsum[1]
\begin{figure}[h!]
\begin{center}
\sbox{\quack}{%
\begin{tikzpicture}
\node[draw,fill,red,circle,radius=5cm] at (0,0) {};
\draw[fill,green,] (2,0) rectangle (4,1);
\end{tikzpicture}%
}
\usebox{\quack}
Width: \the\wd\quack
Height: \the\ht\quack
Depth: \the\dp\quack
\end{center}
\caption{\lipsum[1][1-3]}
\end{figure}
\lipsum[1]
\end{document}
