附录中的图片标题使用 minipage

Question

我正在使用 article 类撰写一篇论文，并使用并排的 2 个图来压缩材料。我正在使用 float 包为附录制作不同的图标签，这样附录图的标题就不会显示在主图列表中。由于某种原因，第一个标题没有显示在附录图中，而第二个标题代替了第一个标题。有什么想法吗？

\documentclass[letterpaper,11pt]{article}
\usepackage{float}
\newfloat{figurea}{htbp}{lofa}[section]
\floatname{figurea}{Figure}
\usepackage{caption}
\captionsetup{labelsep=period,font=small,labelfont=bf,aboveskip=2ex,belowskip=0ex}
\usepackage[title]{appendix}

\begin{document}

\listoffigures
\section{Figures in main body}
\begin{figure}[htb]
  \begin{minipage}[b]{0.48\textwidth}
    \centering
    \framebox[\textwidth]{First fig}
    \caption{First fig.}
    \label{fig1}
  \end{minipage}
  \hfill
  \begin{minipage}[b]{0.48\textwidth}
    \centering
    \framebox[\textwidth]{Second fig}
    \caption{Second fig.}
    \label{fig2}
  \end{minipage}
\end{figure}

\begin{appendices}
\section{Figures in appendix}
\begin{figurea}[htb]
  \begin{minipage}[b]{0.48\textwidth}
    \centering
    \framebox[\textwidth]{First figa}
    \caption{First figa.}
    \label{figa1}
  \end{minipage}
  \hfill
  \begin{minipage}[b]{0.49\textwidth}
    \centering
    \framebox[\textwidth]{Second figa}
    \caption{Second figa.}
    \label{figa2}
  \end{minipage}
\end{figurea}
\end{appendices}

\end{document}

Answer 1

使用完全支持的 float 包caption-newfloat：

\documentclass{article}

\usepackage{newfloat}
\DeclareFloatingEnvironment[
  fileext = lofa,
  placement = htbp,
  name = Figure,
  within = section
  ]{figurea}
\usepackage{caption}
\captionsetup{labelsep=period,font=small,labelfont=bf,aboveskip=2ex,belowskip=0ex}
\usepackage[title]{appendix}

\begin{document}

\listoffigures
\section{Figures in main body}
\begin{figure}[htb]
  \begin{minipage}[b]{0.48\textwidth}
    \centering
    \framebox[\textwidth]{First fig}
    \caption{First fig.}
  \end{minipage}
  \hfill
  \begin{minipage}[b]{0.48\textwidth}
    \centering
    \framebox[\textwidth]{Second fig}
    \caption{Second fig.}
  \end{minipage}
\end{figure}

\begin{appendices}
\section{Figures in appendix}
\begin{figurea}[htb]
  \begin{minipage}[b]{0.48\textwidth}
    \centering
    \framebox[\textwidth]{First figa}
    \caption{First figa.}
  \end{minipage}
  \hfill
  \begin{minipage}[b]{0.49\textwidth}
    \centering
    \framebox[\textwidth]{Second figa}
    \caption{Second figa.}
  \end{minipage}
\end{figurea}
\end{appendices}

\end{document}

Answer 2

解决方案floatrow。注意float必须加载后floatrow (或用它替换)：

\documentclass[letterpaper,11pt]{article}
\usepackage{floatrow}%
\DeclareNewFloatType{figurea}
{placement=htbp, name=Figure, within=section, fileext=lofa}
\renewcommand\thefigurea{\arabic{figurea}}
\newfloatcommand{ffigabox}{figurea}[\nocapbeside][]
\usepackage{caption}
\captionsetup{labelsep=period,font=small,labelfont=bf,aboveskip=2ex,belowskip=0ex}
\usepackage[title]{appendix}

\usepackage{float}
 \begin{document}

\listoffigures

\section{Figures in main body}

\begin{figure}[!ht]
 \begin{floatrow}
\ffigbox{\caption{First fig.} \label{fig1}}{\framebox[0.48\textwidth]{First fig}}
 \ffigbox{\caption{Second fig.} \label{fig2}}{\framebox[0.48\textwidth]{Second fig}}
 \end{floatrow}
\end{figure}

\begin{appendices}

\section{Figures in appendix}

\begin{figurea}[htb]
  \begin{floatrow}%
    \ffigabox{\caption{First figa.} \label{figa1}}{\framebox[0.48\textwidth]{First figa}}
    \ffigabox{ \caption{Second figa.} \label{figa2}}{\framebox[0.48\textwidth]{Second figa}}
  \end{floatrow}
\end{figurea}
\end{appendices}

\end{document}
