为什么文字没有环绕图像？

Question

为什么 \lipsum 可以工作，但实际文本却不行？我希望能够输入自己的文本。

这个问题出自于没有得到这个答案上班。

非常感谢您的帮助。

Answer 1

\lipsum定义以段落结尾，需要在前面留一个空行，如下所示\endgroup，或者更安全如果在文本剪切完成之前组有可能结束，则根本不要将 wrapfig 放在组中。

请注意，\columnsep 如果您有一个两列文档并且分页符恰好落在更改​​范围内，则在文档内进行更改将产生奇怪的效果。

Answer 2

归零设置\intextsep错误（尝试一下）。

最好定义自己的版本wrapfigure，而不是依赖文档中的代码重复。有必要使用\wrapfloat和\endwrapfloat构建类似于标准环境的新环境。

\documentclass{article}
\usepackage{graphicx,lipsum,wrapfig}

\newenvironment{lydiawrapfigure}
 {%
%  \setlength{\intextsep}{0pt}% <--- Wrong!
  \setlength{\columnsep}{15pt}%
  \wrapfloat{figure}%
 }
 {\endwrapfloat}

\begin{document}

\begin{lydiawrapfigure}{r}{0.45\textwidth}
\centering
  \includegraphics[width=\linewidth]{example-image-a}
  \caption{Caption}\label{versusMABs}
\end{lydiawrapfigure}

\lipsum[1]

\begin{lydiawrapfigure}{r}{0.45\textwidth}
\centering
  \includegraphics[width=\linewidth]{example-image-a}
  \caption{Caption}\label{versusMABs2}
\end{lydiawrapfigure}
