[Tex/LaTex] Wrong behaviour of wrapfigure environment when using “placement = outer”

koma-scriptwrapfigure

I'm trying to place some pictures inside my text using the wrapfig package of Donald Arseneau with KOMAscript of Markus Kohm. The intention is to place the pictures partly in the margin area at the outer side of a twosided document.

According to the package documentation I have to set the placement parameter value to the capital letter O to gain the outside edge–far from the binding, and the overhang parameter to a value of how much the figure should hang out into the margin.

That's what I have done in the attached minimum working example. As you can see in the attached picture, this works fine on odd pages, but the picture is misplaced on even pages.

Additional it seems that the overhang parameter — different from the manual's description — specifies the value how much the figure should hang into the text (not the margin).

Is it my fault, or a bug in the package?

\documentclass[twoside]{scrartcl}

\usepackage[ngerman]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{blindtext}

\begin{document}

\section{Hello, World!}
\Blindtext

\begin{wrapfigure}{O}{1cm}
    \includegraphics[width=3cm]{qr}
\end{wrapfigure}
\Blindtext

\blindtext

\begin{wrapfigure}{O}{1cm}
    \includegraphics[width=3cm]{qr}
\end{wrapfigure}
\Blindtext

\end{document}

I can make out that you have seen the manual, but still have a look at this:

Now in this:

\begin{wrapfigure}{O}{1cm}

you haven't specified the overhang but the width as 1cm and putting a picture of width=3cm.

Let us correct it:

\begin{wrapfigure}{O}[1cm]{3cm}

Here overhang is 1cm and total width is 3cm.

The code:

\documentclass[twoside]{scrartcl}

\usepackage[ngerman]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{blindtext}

\begin{document}

\section{Hello, World!}
\Blindtext

\begin{wrapfigure}{O}[1cm]{3cm}
    \includegraphics[width=3cm]{example-image-a}
\end{wrapfigure}
\Blindtext

\blindtext

\begin{wrapfigure}{O}[1cm]{3cm}
    \includegraphics[width=3cm]{example-image-b}
\end{wrapfigure}
\Blindtext

\end{document}

[Tex/LaTex] Textwidth wrong after wrapfigure

To cite the manual of the wrapfig package, page 1:

You must not specify a wrapfigure in any type of list environment or or immediately before or immediately after one. It is OK to follow a list if there is a blank line (\par) in between.

[...]

\linewidth is now adjusted within the wrapped text, but since it can only be set for whole paragraphs at a time, it will persist with the wrong value after the wrapping, until the paragraph is finished.

And at page 2:

For esthetic reasons, only plain text should wrap around the figure. Section titles and big equations look bad; lists are bad if the figure is on the left. (All these function properly, they just don’t look very good.) Small equations look fine.

Thus: Put a \par before \begin{formel}:

\documentclass{book}
\usepackage{graphicx}
\usepackage{amsthm}
\usepackage{wrapfig}
\usepackage{mdframed}

\newtheoremstyle{mystyle}{}{}{}{}{}{}{0.5em}{}
\theoremstyle{mystyle}
\newmdtheoremenv{formel}{Formel}

%\usepackage{picins}

\begin{document}
\begin{wrapfigure}{l}{8cm}
  \includegraphics[scale=0.48]{example-image-a}
\end{wrapfigure}
text 
\par
\makeatletter
\loop
\ifnum\c@WF@wrappedlines>3
\hspace*{1sp}\newline
\advance\c@WF@wrappedlines by -1
\repeat
\makeatother
\par
\begin{formel}[Formel]
$1+1=2$
\end{formel}
\end{document}

If the text to be wrapped is too short, the formula would be placed in the wrapped text, where it has the smaller width, of course. (And an additional \usepackage{picins} is needed, otherwise the formula is printed "over" the picture.) Using \c@WF@wrappedlines of the wrapfig package and automatically inserting the appropriate number of empty lines fixes this.

[Tex/LaTex] Strange behaviour of wrapfigure if followed by equation

I can't profess to understand the internals of what brought on the problem to begin with; however, placing a \leavevmode after the \end{wrapfigure} resolves the issue.

I inferred the answer from the observed behavior that adding some text after the wrapfigure also resolves the issue. One thing that adding text does is take you out of vertical mode, so I tried leaving vertical mode as a solution, and it worked. Is that a bug with wrapfig? I couldn't say.

(For the rest of the readers, commenting that one line will re-create the problem.)

\documentclass[a4paper, 12pt]{article} 

\usepackage{wrapfig} % to have text around figures
\usepackage[demo]{graphicx}   
\usepackage{amsmath}

\begin{document}
\subsubsection*{Sample Subsection}
\begin{wrapfigure}{r}{0.25\textwidth}
    \includegraphics[width=0.23\textwidth]{sampleFigure}
    \caption{Heat Balance for the ceiling node}
\end{wrapfigure}
\leavevmode% THIS RESOLVED IT
\begin{equation*}
    a^2+b^2=c^2
\end{equation*}
with 
\begin{align*}
    a^2+b^2&=c^2 & a^2+b^2&=c^2 \\
    a^2+b^2&=c^2 & a^2+b^2&=c^2 \\
    a^2+b^2&=c^2 & a^2+b^2&=c^2
\end{align*}
can be solved to
\begin{equation}
   a^2+b^2=c^2
\end{equation}

\begin{wrapfigure}{r}{0.25\textwidth}
    \includegraphics[width=0.23\textwidth]{sampleFigure}

-> With some text it is working!
\begin{equation*}
