Watermark on document image or custom boxes

Question

I have added water mark using \backgroundsetup

\backgroundsetup{
angle=45,
scale=1,contents={\includegraphics[allpages,
    ]{water_mark.png}}}

\usepackage[most]{tcolorbox}\tcbset{colback=blue!8!white,colframe=blue!25!white, boxrule=0pt, left=10pt,right=10pt,top=10pt,bottom=10pt, arc=0pt,outer arc=0pt}

\begin{tcolorbox}\begin{verbatim} texts in box\end{verbatim} \end{tcolorbox}

This what I have achieved:

I am happy to see the watermark in every page but the problem is that some pages have images and custom boxes, in such pages the watermark is below that images and boxes. I want the watermark above the image or box.

Answer 1

Instead of using background package, you could use xwatermark.

Its starred (*) variant of \newwatermark command puts the watermark in the foreground instead of the background.

\documentclass{article}
\usepackage[printwatermark]{xwatermark}

\usepackage[most]{tcolorbox}
\tcbset{colback=blue!8!white,colframe=blue!25!white, boxrule=0pt, left=10pt,right=10pt,top=10pt,bottom=10pt, arc=0pt,outer arc=0pt}

\usepackage{mwe}% for test purpose only, you don't need to use this in your document

\begin{document}

\newwatermark*[angle=45,scale=1,xpos=0,ypos=40, allpages]{\includegraphics[height=2cm,width=10cm]{example-image}}% put your image here with the correct height and width

\section{An example of section}

\blindtext

\begin{tcolorbox}
\begin{verbatim} 
texts in box
\end{verbatim} 
\end{tcolorbox}

\blindtext
\newpage
\blindtext
\end{document}
