减少子标题框中的图像大小而不减少标题宽度

Question

我使用subcaptionbox来对齐图像和标题，因为我的标题长度不同。但是，我无法缩小图像的尺寸。如果我更改宽度，标题宽度也会更改。我想保持相同的宽度，但图像要小一些。

\documentclass{article}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}
\begin{figure}
\centering
\subcaptionbox{person, shirt
\label{fig:shirtperson}}
{\includegraphics[width=.24\linewidth]
{figures/shirtperson}}
\hfill 
\subcaptionbox{person, shirt, jacket
\label{fig:shirtjacketperson}}
{\includegraphics[width=.24\linewidth]
{figures/shirtjacketperson}}\hfill
\subcaptionbox{person, shirt, jacket, glasses\label{fig:shirtjacketglassesperson}}
{\includegraphics[width=.24\linewidth]
{figures/shirtjacketglassesperson}}
\hfill
\subcaptionbox{person, stripedshirt
\label{fig:stripedshirtperson}}
{\includegraphics[width=.24\linewidth]
{figures/stripedshirtperson}}
\caption{Image product variants}
\label{fig:imageproductvariants}
\end{figure} 
\end{document}

Answer 1

您可以使用以下\includegraphics设置包围\makebox宽度\makebox[<width>][<alignment>]{\includegraphics[<options>]{<image>}}：

\documentclass[]{article}

\usepackage{subcaption}
\usepackage{graphicx}

\begin{document}

\begin{figure}
\centering
\subcaptionbox{person, shirt
\label{fig:shirtperson}}
{\makebox[0.24\linewidth][c]{\includegraphics[width=.1\linewidth]
    {example-image-a}}}
\hfill 
\subcaptionbox{person, shirt, jacket
\label{fig:shirtjacketperson}}
{\includegraphics[width=.24\linewidth]
{example-image-b}}\hfill
\subcaptionbox{person, shirt, jacket, glasses\label{fig:shirtjacketglassesperson}}
{\includegraphics[width=.24\linewidth]
{example-image-a}}
\hfill
\subcaptionbox{person, stripedshirt
\label{fig:stripedshirtperson}}
{\includegraphics[width=.24\linewidth]
{example-image-b}}
\caption{Image product variants}
\label{fig:imageproductvariants}
\end{figure} 

\end{document}

Answer 2

我更愿意使用可选参数 '[⟨width⟩]' \subcaptionbox：

\subcaptionbox[⟨list entry⟩]{⟨heading⟩}[⟨width⟩][⟨inner-pos⟩]{⟨contents⟩}

以下是代码：

\documentclass{article}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}
\begin{figure}
    \centering
    \subcaptionbox{person, shirt
        \label{fig:shirtperson}}
    [.24\linewidth]
    {\includegraphics[width=.5\linewidth]
        {example-image}}
    \hfill
    \subcaptionbox{person, shirt, jacket
        \label{fig:shirtjacketperson}}
    {\includegraphics[width=.24\linewidth]
        {example-image-a}}\hfill
    \subcaptionbox{person, shirt, jacket, glasses\label{fig:shirtjacketglassesperson}}
    {\includegraphics[width=.24\linewidth]
        {example-image-b}}
    \hfill
    \subcaptionbox{person, stripedshirt
        \label{fig:stripedshirtperson}}
    {\includegraphics[width=.24\linewidth]
        {example-image-c}}
    \caption{Image product variants}
    \label{fig:imageproductvariants}
\end{figure}
\end{document}

其实在子标题的文档中已经有了对此的详细描述：
