I am trying to set a semi-transparent background for some text, so we can see the image behind it. To do so, I am using tcolorbox. However, it seems that I can not get it working with the leaflet document class.

Any suggestions?

\documentclass[10pt,a4paper]{leaflet}
\usepackage[many]{tcolorbox}

\newtcolorbox{mybox}[1][]{
width=\textwidth,
arc=2mm,
% auto outer arc,
boxsep=0cm,
toprule=0.5pt,
leftrule=0.5pt,
bottomrule=0.5pt,
rightrule=0.5pt,
colframe=black,
colback=white!25,
breakable,
nobeforeafter,
enhanced jigsaw,
opacityframe=0.1,
opacityback=0.5
}

\AddToBackground{1}{\put(0,415){\includegraphics[width=9.9cm]{example-image-c}}}

\begin{document}

\begin{mybox}[]
    \begin{itemize}
        \item a
        \item b
        \item c
        \item d
    \end{itemize}
\end{mybox}

\end{document}

The leaflet class empties the shipout hooks and this means that tikz can't add the needed resources to the page. With a current (!) LaTeX you could try to use the new pdfmanagement. It uses a different hook that is not affected by leaflet:

\DocumentMetadata{} %load new pdfmanagement, requires current latex
\documentclass[10pt,a4paper]{leaflet}
\usepackage[many]{tcolorbox}

\newtcolorbox{mybox}[1][]{
width=\textwidth,
arc=2mm,
% auto outer arc,
boxsep=0cm,
toprule=0.5pt,
leftrule=0.5pt,
bottomrule=0.5pt,
rightrule=0.5pt,
colframe=black,
colback=white!25,
breakable,
nobeforeafter,
enhanced jigsaw,
opacityframe=0.1,
opacityback=0.5
}

\AddToBackground{1}{\put(0,415){\includegraphics[width=9.9cm]{example-image-c}}}

\begin{document}

\begin{mybox}[]
    \begin{itemize}
        \item a
        \item b
        \item c
        \item d
    \end{itemize}
    
\end{mybox}

\end{document}

  • @Tom with the newest pdflatex, or with pdflatex-dev, or with by first loading pdfmanagement-testphase

  • I see. Thank you! I try it successfully on local compile. But not working on overleaf, that's could need some time.

  • @Tom On overleaf you could try to load pdfmanagement-testphase and then use \DeclareDocumentMetadata as command (we shortened the name in newer latex). But I'm not sure if all the needed patches are already there in overleaf.

    @Philippe add this \RequirePackage{pdfmanagement-testphase} \DeclareDocumentMetadata{} before \documentclass command.
