# Picture as “numbering” for section?

is there a chance to use a small picture (like 60x25 px) as "numbering" for sections (or maybe as a item-marker in the item-environment?) An example of a picture is this one .

Edit: I think one could use a itemize list for it, but I would like to customize the section "markers" to this picture. The same picture for each section. I don't need the number of the sections. I just want the picture to be on the left margin to indicate the beginning of a new section. Like a customization for \section*{New Topic}

• Welcome to TeX.SE. This is possible, but how does the picture change if the section number changes? (One thing to consider: A picture can't enter the bookmarks section of a pdf file, however). Changing \thesection is no good idea! – user31729 Apr 23 '17 at 21:28
• Sure. That's easy. – Ulrike Fischer Apr 23 '17 at 21:29
• In my case it's no necessary to use a toc, the picture doesn't need to change and the sections are more like a list of items. – Michael Schmid Apr 23 '17 at 21:35
• @MichaelSchmid: A pure itemize list? – user31729 Apr 23 '17 at 21:37
• You should take a look t the documentation of titlesec. – Bernard Apr 23 '17 at 21:46

A quick and dirty method for \section and all other section commands below that level is to redefine \@seccntformat to ignore the usual \csname the#1\endcsname and insert another command in there, which should be robust, however.

This could be basically anything, in the example I showed a quick tikz shaded ball, but an image can be included and scaled accordingly.

\documentclass{article}

\usepackage{graphicx}
\usepackage{tikz}

\DeclareRobustCommand{\picturetodisplay}{\includegraphics[scale=0.05]{ente}}

% Redefine it

\makeatletter
\makeatother

\begin{document}

\section{A nice section}

\section{Another nice section}

\section{Yet another nice section}

\end{document}


Shifting the 'section number' to the margin:

\documentclass{article}

\usepackage{showframe}

\usepackage{graphicx}
\usepackage{tikz}

\makeatletter
\makeatother

\begin{document}

\section{A nice section}

\section{Another nice section}

\DeclareRobustCommand{\picturetodisplay}{\includegraphics[scale=0.03]{ente}}

\section{Yet another nice section}

\end{document}


• This way sections look like itemize lists – user31729 Apr 23 '17 at 22:11
• And then I have to replace the text in the second {} of the redefinition to something like "/path/to/the/picture.jpg" ? – Michael Schmid Apr 23 '17 at 22:13
• @MichaelSchmid: If you mean \includegraphics: Yes! The usual call is \includegraphics[some options]{path/to/the/picture.jpg], The options might be scaling, height, rotating even, if needed, but I don't recommend that in the section heading line – user31729 Apr 23 '17 at 22:18
• Thank you very much! Do you have a idea how to make the text of the sections start at the beginning of the \textwidth-area? So the picture (section-marker) is in the left margin. – Michael Schmid Apr 23 '17 at 22:20
• @MichaelSchmid: That's changing the question ;-) – user31729 Apr 23 '17 at 22:23
