如何让图形框架向内扩展？

我怎样才能让红色框架向内扩展？例如，下面的代码生成一个向外扩展的框架。我怎样才能让它向内扩展，这样它就不会占用图形之外的任何额外空间？例如\frame(color=(1,0,0),width=0.1mm,expand_inwards=True){\includegraphics[width=\imagewidth]{example-image-a}}

\documentclass{article}

\usepackage{graphicx}

\begin{document}


\begin{figure}
    \centering
    \def\imagewidth{0.12\textwidth}%
    \includegraphics[width=\imagewidth]{example-image-a}\\
    \frame{\includegraphics[width=\imagewidth]{example-image-a}}
    \caption{Caption}
    \label{fig:my_label}
\end{figure}

答案1

\fbox和之间存在有趣的交互\includegraphics，因此我的解决方案是排版具有零宽度和\fbox适当尺寸的图形。

\documentclass{article}
\usepackage{graphicx}

\NewDocumentCommand{\frameincludegraphics}{O{}m}{%
  \begingroup
  \sbox{0}{\includegraphics[#1]{#2}}%
  \setlength{\fboxrule}{0.4mm}% exaggerated to better see the effect
  \setlength{\fboxsep}{-\fboxrule}%
  \makebox[0pt][l]{\usebox{0}}%
  \fbox{\rule{0pt}{\ht0}\rule{\wd0}{0pt}}%
  \endgroup
}

\begin{document}

\begin{figure}
\centering

\includegraphics[width=0.12\textwidth]{example-image-a}

\frameincludegraphics[width=0.12\textwidth]{example-image-a}

\caption{Caption}
\label{fig:my_label}

\end{figure}

\end{document}

我这样做0.4mm只是为了让框架更加清晰可见。

如果您想要彩色框架，可以添加尾随颜色可选参数。

\documentclass{article}
\usepackage{graphicx,xcolor}

\NewDocumentCommand{\frameincludegraphics}{O{}mO{black}}{%
  \begingroup
  \sbox{0}{\includegraphics[#1]{#2}}%
  \setlength{\fboxrule}{0.4mm}%
  \setlength{\fboxsep}{-\fboxrule}%
  \makebox[0pt][l]{\usebox{0}}%
  {\color{#3}\fbox{\rule{0pt}{\ht0}\rule{\wd0}{0pt}}}%
  \endgroup
}

\begin{document}

\begin{figure}
\centering

\includegraphics[width=0.12\textwidth]{example-image-a}

\frameincludegraphics[width=0.12\textwidth]{example-image-a}

\frameincludegraphics[width=0.12\textwidth]{example-image-a}[red!60]

\caption{Caption}
\label{fig:my_label}

\end{figure}

如果您使用\frame、\fbox或\framebox，则问题在于，某些规则会在内容之前绘制。因此，您必须修剪内容以避免其超出已绘制的规则。另一个建议是，先绘制图像，然后绘制具有所需大小的框架：

\documentclass{article}

\usepackage{graphicx}

\newlength{\imageheight}

\begin{document}
%\setlength{\fboxrule}{1ex}% Try to see what happens with fat rules

\begin{figure}
    \centering
    \def\imagewidth{0.12\textwidth}%
    \settoheight{\imageheight}{\includegraphics[width=\imagewidth]{example-image-a}}%
    \fboxsep=0pt
    \includegraphics[width=\imagewidth]{example-image-a}\\
    \makebox[0pt][l]{\includegraphics[width=\imagewidth]{example-image-a}}%
    \raisebox{\fboxrule}{\framebox[\imagewidth]{\rule{0pt}{\dimexpr\imageheight-2\fboxrule}}}%
    \caption{Caption}
    \label{fig:my_label}
\end{figure}

\end{document}

或者，您可以使用包按规则宽度剪辑内容trimclip：

\documentclass{article}

\usepackage{graphicx,trimclip}

\begin{document}

\begin{figure}
    \centering
    \def\imagewidth{0.12\textwidth}%
    \fboxsep=0pt
    \includegraphics[width=\imagewidth]{example-image-a}\\
    \framebox[\imagewidth]{\clipbox{\fboxrule}{\includegraphics[width=
        \imagewidth]{example-image-a}}}\\
    \setlength{\fboxrule}{1ex}
    \fbox{\clipbox{\fboxrule}{\includegraphics[width=
        \imagewidth]{example-image-a}}}\\
    \caption{Caption}
    \label{fig:my_label}
\end{figure}

\end{document}

您还可以\color在之前使用\fbox或将放入命令\fbox中\textcolor或替换\fbox为来\fcolorbox更改框架的颜色：

\documentclass{article}

\usepackage{graphicx,trimclip,xcolor}

\begin{document}

\begin{figure}
    \centering
    \def\imagewidth{0.12\textwidth}%
    \fboxsep=0pt
    \includegraphics[width=\imagewidth]{example-image-a}\\
    \framebox[\imagewidth]{\clipbox{\fboxrule}{\includegraphics[width=
        \imagewidth]{example-image-a}}}\\
    \setlength{\fboxrule}{1ex}%
    \textcolor{green}{%
    \fbox{\clipbox{\fboxrule}{\includegraphics[width=
        \imagewidth]{example-image-a}}}}\\
    \fcolorbox{blue}{white}{\clipbox{\fboxrule}{\includegraphics[width=
      \imagewidth]{example-image-a}}}\\
    \caption{Caption}
    \label{fig:my_label}
\end{figure}

解决方案是使用 \textcolor 和 \frame。比 fbox 更好，因为它不会移动图形。

\documentclass{article}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{float}
\usepackage{subfig}
\usepackage{tikz}% loads graphicx
\usepackage{graphicx,xcolor}

\begin{document}

\makeatletter
\newcommand{\definetrim}[2]{%
  \define@key{Gin}{#1}[]{\setkeys{Gin}{trim=#2,clip}}%
}
\makeatother

\definetrim{kit_mocap}{0 0 0 0} % {left bottom right top}
\def\barheight{0.015}
\def\imagewidth{0.12\textwidth}
\def\imagehspace{\hspace{-0.2em}}
\def\imagevspace{\vspace{-0.3cm}}
\setlength{\fboxrule}{1pt}
\setlength{\fboxsep}{0pt}
