A user asked a question about scaling a figure to a factor of \textwidth and got an answer like this:

\documentclass{article} \usepackage{graphicx} \begin{document} \includegraphics[width=0.5\textwidth]{file} \end{document}

however, I'm not sure how to apply this to my document:

\documentclass{article} \usepackage{graphicx} \usepackage{tikz} \begin{document} \begin{figure}[!h] \centering \begin{tikzpicture} % \end{tikzpicture} \caption{This figure has a width which is a factor of \\textwidt} \end{figure} \end{document}

I've tried

\begin{figure}[!h, width=\textwidth]

but that didn't work.

  • That solution would work if you produce a single file containing the image produced by the tikz. Commented Jan 22, 2014 at 0:15

    @sigur yes but I have dozens of tikz figures and I don't want the source for my document to be spread across dozens of files that I need to keep, backup, and maintain constantly. There must be a way to scale it. \resizebox[\textwidt][!]{...} doesn't seem to work either. Commented Jan 22, 2014 at 0:25
  • In this case you have to scale the tikz using \begin{tikzpicture}[scale=.7] for example. But this will change the scale of coordinates. Commented Jan 22, 2014 at 0:26
  • \resizebox works. You should use it as follows: \resizebox{\textwidth}{!}{\begin{tikzpicture}...\end{tikzpicture}} Commented Jan 22, 2014 at 0:30

You need tikzscale package. Save the contents 

\begin{tikzpicture} \draw (0,0) circle (2cm); \node at (0,0) {Me}; \end{tikzpicture}

as myfig.tikz (say) and use \includegraphics

Code:

\documentclass{article} \usepackage{tikz} \usepackage{tikzscale} \usepackage{filecontents} %% only for this demo \begin{filecontents*}{myfig.tikz} \begin{tikzpicture} \draw (0,0) circle (2cm); \node at (0,0) {Me}; \end{tikzpicture} \end{filecontents*} \begin{document} \begin{figure}[htb] \centering \includegraphics[width=0.5\textwidth]{myfig.tikz} \caption{This figure has a width which is a factor of text width} \end{figure} \begin{figure}[htb] \centering \includegraphics[width=0.2\textwidth]{myfig.tikz} \caption{This figure has a width which is a factor of text width} \end{figure} \end{document}

Unlike \resizebox, the fonts are not scaled in-appropriately. If you want to scale fonts too, use \begin{tikzpicture}[transform shape] instead of \begin{tikzpicture}.

With \resizebox from graphicx:

\documentclass{article} \usepackage{tikz} \begin{document} \begin{figure}[htb] \centering \resizebox{0.5\textwidth}{!}{% \begin{tikzpicture} \draw (0,0) circle (2cm); \node at (0,0) {Me}; \end{tikzpicture} }% \caption{This figure has a width which is a factor of text width} \end{figure} \begin{figure}[htb] \centering \resizebox{0.2\textwidth}{!}{% \begin{tikzpicture} \draw (0,0) circle (2cm); \node at (0,0) {Me}; \end{tikzpicture} }% \caption{This figure has a width which is a factor of text width} \end{figure} \end{document}

    If the fonts are not scaled, then unfortunately I cannot use this method. Commented Jan 22, 2014 at 0:43

    @user41709 Scaling fonts is a bad idea. Any way it is your document. You can use \resizebox then. Commented Jan 22, 2014 at 0:45
  • @user41709: You can still use this method, I think, if you pass the transform shape option to tikzpicture. Commented Jan 22, 2014 at 0:46

    @HarishKumar The issue is I've spent weeks on all the content and figures for one document, and now for a different conference we need to use a template with a significantly narrower text width. I simply do not have the time to re-create these figures for the larger page margins. Commented Jan 22, 2014 at 0:50

    So my best option is to compile each figure as a separate PDF file, and include them with a scale? That will scale everything correctly? Commented Jan 22, 2014 at 0:59

You may want to consider package adjustbox as well.

\documentclass{article} \usepackage{graphicx,adjustbox} \usepackage{tikz} \begin{document} \begin{figure}[!h] \centering \begin{tikzpicture} \draw (0,0) rectangle (10,2); \end{tikzpicture} \caption{This figure uses no factor} \end{figure} \begin{figure}[!h] \centering \begin{adjustbox}{max width=0.5\textwidth} \begin{tikzpicture} \draw (0,0) rectangle (10,2); \end{tikzpicture} \end{adjustbox} \caption{This figure uses 0.5 factor} \end{figure} \begin{figure}[!h] \centering \begin{adjustbox}{max width=0.7\textwidth} \begin{tikzpicture} \draw (0,0) rectangle (10,2); \end{tikzpicture} \end{adjustbox} \caption{This figure uses factor 0.7} \end{figure} \end{document}
