保持一个子图固定，将另一个子图向右移动

Question

你好，我想将子图（b）向右侧移动，与该图顶部的线完全对齐。

\begin{figure*} 
\centering
\begin{subfigure}[t]{0.5\textwidth}
\centering
\includegraphics[scale=0.65]{a.pdf}
\caption{}
\end{subfigure}
~
\begin{subfigure}[t]{0.5\textwidth}
\centering
\includegraphics[height=1.8in, width=2.3in]{b.pdf}
\caption
\end{subfigure}
\end{figure*}

任何帮助都将非常感激。

Answer 1

如果您确定第二个数字应为 1.8 英寸高，那么这\subcaptionbox就是您想要的：

\documentclass[twocolumn]{article}

\usepackage{subcaption}
\usepackage{graphicx}

% the following are just for the example
\usepackage{kantlipsum} % mock text
\usepackage{fancyhdr} % just to show the top rule
\pagestyle{fancy}


\begin{document}

\kant

\begin{figure*} 
\centering
\subcaptionbox{}{\includegraphics[height=1.8in]{example-image-16x9.pdf}}%
\hfill
\subcaptionbox{}{\includegraphics[height=1.8in, width=2.3in]{example-image-9x16.pdf}}

\caption{Cumulative caption}
\end{figure*}

\kant

\end{document}
