当图片位于环境 \begin 之后时，如何包装图片？

Question

我正在尝试在环境中包装图片。我看到那里的人们insbox.tex在不同的答案中推荐使用。下面的代码一切都很好。但是，当图片被引入后，\begin{group}它根本不起作用。

编辑：我不\leavevmode这么认为。

看看我的 MWE：

\documentclass{book}
\usepackage{amsthm}
\usepackage{lipsum}
\newtheorem{thm}{Theorem}
\usepackage{graphicx}
\usepackage[font=footnotesize]{caption}
\input{insbox.tex}
\usepackage{threeparttable}
\usepackage{xargs}

\newcommand\insertpictureR[3][5]{
\InsertBoxR{0}{\begin{threeparttable}\begin{tabular}{c@{}}\includegraphics[width=#3\textwidth]{#2}\end{tabular}\captionof{figure}{}\end{threeparttable}}[#1]%
}
\newcommand\insertpictureL[3][5]{
\InsertBoxL{0}{\begin{threeparttable}\begin{tabular}{c@{}}\includegraphics[width=#3\textwidth]{#2}\end{tabular}\captionof{figure}{}\end{threeparttable}}[#1]%
}

\begin{document}
\begin{thm}
\insertpictureR{example-image-a}{0.2}
\lipsum[1]
\end{thm}

\begin{proof}
\insertpictureL{example-image-a}{0.2}
\lipsum[1]
\end{proof}
\end{document}

Answer 1

您缺少了\leavevmode和一些其他好东西。请注意，您的宏似乎系统地要求使用可选参数（也许没有正确考虑标题高度？）。

\documentclass{book}
\usepackage{amsthm}
\usepackage{lipsum}
\newtheorem{thm}{Theorem}
\usepackage{graphicx}
\usepackage[font=footnotesize]{caption}
\input{insbox.tex}
\usepackage{threeparttable}
\usepackage{xargs}

\newcommand\insertpictureR[3][5]{
\InsertBoxR{0}{\begin{threeparttable}\begin{tabular}{c@{}}\includegraphics[width=#3\textwidth]{#2}\end{tabular}\captionof{figure}{}\end{threeparttable}}[#1]%
}
\newcommand\insertpictureL[3][5]{
\InsertBoxL{0}{\begin{threeparttable}\begin{tabular}{c@{}}\includegraphics[width=#3\textwidth]{#2}\end{tabular}\captionof{figure}{}\end{threeparttable}}[#1]%
}

\begin{document}

\begin{thm} \leavevmode
\insertpictureR[3]{example-image-a}{0.2}\noindent
\lipsum[1]
\end{thm}%



\begin{proof}
\leavevmode\insertpictureL[3]{example-image-a}{0.2}\noindent
\lipsum[1]
\end{proof}

\end{document}
