子图标题中的水平文本对齐

Question

子图中的标题默认是两端对齐的，但看起来并不总是很漂亮：

\documentclass[]{tGIS2e} % http://www.tandf.co.uk/journals/authors/tgislatex.zip

\begin{document}

\begin{figure}
\begin{center}
%\raggedright
\subfigure[caption for a]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_a}%
}
~
\subfigure[capture for b, justified]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_b}%
}
~
\subfigure[justification becomes ugly sometimes]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_c}%
}
~
\subfigure[there should be a way of applying \textbackslash raggedright or a similar command ]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_d}%
}
\caption{Figure example}%
\label{fig:myfig}
\end{center}
\end{figure}

\end{document}

如何才能保持图像和其标题的整体对齐，并使子标题对齐，比如说左对齐？添加\raggedright没有帮助——它使整个图像向左移动，但保持文本的对齐。

如果解决方案针对上面给出的标记退出就好了，因为我使用的模板不支持subfigure环境并且与subcaption包冲突。

您的 documentclass 正在加载（过时的）subfigure包。此包具有诸如raggedright标题对齐之类的选项。可以通过发出以下命令在本地启用这些选项\subcapraggedrighttrue：

\documentclass[]{tGIS2e}

\begin{document}

\begin{figure}
\begin{center}
\subcapraggedrighttrue
\subfigure[caption for a]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_a}%
}
~
\subfigure[capture for b, justified]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_b}%
}
~
\subfigure[justification becomes ugly sometimes]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_c}%
}
~
\subfigure[there should be a way of applying \textbackslash raggedright or a similar command ]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_d}%
}
\caption{Figure example}%
\label{fig:myfig}
\end{center}
\end{figure}
\begin{figure}
\begin{center}
\subcapcentertrue
\subfigure[caption for a]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_a}%
}
~
\subfigure[capture for b, justified]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_b}%
}
~
\subfigure[justification becomes ugly sometimes]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_c}%
}
~
\subfigure[there should be a way of applying \textbackslash raggedright or a similar command ]{
    \includegraphics[width=3cm,height=3cm]{example-image-a}%
    \label{fig:myfig_d}%
}
\caption{Figure example}%
\label{fig:myfig}
\end{center}
\end{figure}
\end{document}

可能的命令列表包括

• \subcapraggedrighttrue
• \subcapcentertrue
• \subcapcenterlasttrue

此外，还有false变体。

同样，要\subcaphangtrue确保标签突出到标题块的左侧。例如，在上面的例子中

\subcapraggedrighttrue
\subcaphangtrue

给

选项也nooneline对应于\subcapnoonelinetrue。请参阅Declaration of Optionssubfigure文档，您将能够推断如何将标题放在图形上方而不是下方，等等。

如果您不介意标题相对于(a)、、(b)...标签偏移，也不介意指定标题宽度，那么这可以起作用。

\documentclass{article}
\usepackage{subfigure}
\usepackage[demo]{graphicx}
\textwidth 6in
\newcommand\tparbox[2]{\protect\parbox[t]{#1}{\protect\raggedright #2}}
\begin{document}
\begin{figure}
\begin{center}
\subfigure[\tparbox{2.5cm}{caption for a}]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_a}%
}
~
\subfigure[\tparbox{2.5cm}{capture for b, justified}]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_b}%
}
~
\subfigure[\tparbox{2.5cm}{justification becomes ugly sometimes}]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_c}%
}
~
\subfigure[\tparbox{2.5cm}{there should be a way of applying \textbackslash raggedright or a similar command}]{
    \includegraphics[draft,width=3cm,height=3cm]{dummy}%
    \label{fig:myfig_d}%
}
\caption{Figure example}%
\label{fig:myfig}
\end{center}
\end{figure}
\end{document}
