A floating object distorts background watermark

[nanabaahgyan]

Thanks a lot for this package.

I realised with the latest update that a floating object like a figure on a page distorts (changes font type, size, etc.) the text of the watermark on that page. I've tried it on multiple cases and it remains the same. I wonder if this is something you are aware of too.

[callegar]

Was not aware, thanks for reporting. Can you provide a minimal test case? The package now relies on new LaTeX mechanisms and there may be some corner cases.

[nanabaahgyan]

On the page I'm working on with a figure floating object as follows:
\begin{figure}[!ht]
\includegraphics[option]{graphic.png}
\end{figure}
The background watermark has different font and size.

If I remove the environment (\begin{figure} \end{figure}) and use only '\includegraphics...',the behaviour is reverted.

[callegar]

Please be so kind to provide a minimal, but full example with the document class, any package that may be needed to trigger the issue in addition to draftwatermark, etc. You can save the actual .png file. That will really be helpful.

[callegar]

Tried this:

\documentclass{article}
\usepackage{draftwatermark}
\begin{document}
test
\begin{figure}[!ht]
prova
\end{figure}
\end{document}

cannot reproduce...

I have quite a number of packages in use. Importantly, I'm using the exam class.

\documentclass[12pt]{exam}
\usepackage{graphicx} 
\usepackage{geometry}
\usepackage{listings}   
\usepackage[inline]{enumitem}
\usepackage{tikz}
\usepackage[most]{tcolorbox}
\usepackage{draftwatermark} 
\DraftwatermarkOptions{%
 text=Confidential,
 scale=1.2,
 color={[gray]{0.8}},
 angle=55,
 fontsize=5cm
}

[callegar]

Still cannot reproduce with

\documentclass[12pt]{exam}
\usepackage{graphicx}
\usepackage{geometry}
\usepackage{listings}
\usepackage[inline]{enumitem}
\usepackage{tikz}
\usepackage[most]{tcolorbox}
\usepackage{draftwatermark}
\DraftwatermarkOptions{%
  text=Confidential, scale=1.2, color={[gray]{0.8}}, angle=55, fontsize=5cm }
\begin{document}
test
\begin{figure}[!ht]
prova
\end{figure}
\end{document}

the result does not change for me if I comment out (or not) the \begin{figure} \end{figure}.

Hi @callegar,
You are right that the environment does not produce the error I got. At the moment I'm unable to tell exactly what causes it as it keeps changing due to arbitrary actions I take within the document.

But I have attached a zip of the files that produce the error I describe.
Do run the TextWTMRK.tex file from the folder and particularly consider the output on page 8.

Don't hesitate to reach out to me if you need any clarification.

This is what I get (obviously there are no images since I do not have the graphic files). Can you tell me if there is the issue that you are mentioning?

Please compare with my output attached. The issue is the output on page 8 of the attached document.

[callegar]

OK! this is interesting. We have evident differences in the environment and the way in which the default fonts operate and scale. So these are to be investigated. Can you please:

• Try to see if it is possible to distill a smaller test case (for instance producing only two pages one with the watermark as you expect it and one without), that can be compiled without graphic files (you can put anything you want inside a figure environment and it should make no difference), with the smallest possible set of dependencies on other packages (try to remove them one by one, conserving the issue - for instance ulem should not be relevant to it). This is going to be quite useful also in the future as a regression test.
• Let me know all you can about your environment. Are you using texlive? which version? are you on Win, Linux or Mac? Are you using LaTeX, pdflatex, xelatex, lualatex? At what version? What version of draftwatermark are you using?

[nanabaahgyan]

The following is minimal version (using fewer packages to produce the same effect). Please see attached.
TestWTRMRK.pdf

\documentclass[12pt]{exam}
\usepackage{longtable,tabu}
\usepackage{listings}   
\lstset{language=C++,
        basicstyle=\ttfamily, 
        breaklines=true,
        showstringspaces=false 
}
\usepackage{lipsum}
\usepackage{draftwatermark} 
\DraftwatermarkOptions{%
 text=Confidential,
 scale=1.2,
 color={[gray]{0.8}},
 angle=55,
 fontsize=5cm
}
`
Below is a description of my environment:
XeTeX, Version 3.141592653-2.6-0.999993 (TeX Live 2021)
Linux (KDE Neon)
draftwatermark version 57099 (3.0)

[nanabaahgyan]

I just realised that what actually causes the minimal version to fail is the basicstyle=\ttfamily setting for the listings package. Once that is disabled draftwatermark works as expected.

[callegar]

That is interesting.
Now that you have found the incompatibility with listings, I wonder if you could help me with a really minimal testcase, with no dependencies on external files where I might be able to reproduce the issue, to check if such incompatibility can be removed.
In case, thanks in advance.

[callegar]

This is not enough to reproduce the issue for me (even on xelatex):

\documentclass[12pt]{exam}
\usepackage{listings}
\lstset{language=C++,
        basicstyle=\ttfamily, 
        breaklines=true,
        showstringspaces=false 
}
\usepackage{lipsum}
\usepackage{draftwatermark} 
\DraftwatermarkOptions{%
 text=Confidential,
 scale=1.2,
 color={[gray]{0.8}},
 angle=55,
 fontsize=5cm
}

\begin{document}
prova\clearpage
\begin{figure}[ht]
  \centering
  \fbox{\parbox{10cm}{\hspace*{10cm}\\[10cm]}}
\end{figure}
\end{document}
