设置子浮动标题样式

Question

我在用背面并使用 LuaLaTex 作为编译器，我使用 subfloat 来排列我的图像，但我想将标题样式从图 5 更改为图 5(a) 和图 5(b)。当我只使用 subfigure 时，设置很顺利。但当我使用 subfloat 时，它不起作用。这是我的代码。我想知道如何纠正这个问题，谢谢！

Answer 1

在以下 MWE 中，我用该subfigure包替换了已弃用的包subcaption，并相应地调整了命令的使用\subfloat：

\documentclass[letterpaper,twocolumn,12pt]{article}

\usepackage{graphicx}
\usepackage{float} 

\usepackage[font=footnotesize,labelfont=bf]{caption}
\usepackage[labelformat=simple]{subcaption} 
 
\renewcommand{\figurename}{Fig.}  
\renewcommand\thesubfigure{\figurename\thefigure(\alph{subfigure})}

\begin{document}
\begin{figure}[H]
\centering
\subfloat[subfloat don't work, i want it to be Fig.1(a)]{\label{fig:1}\includegraphics[width=0.4\textwidth]{example-image-a}}
\end{figure}

\begin{figure}[H]
\ContinuedFloat
\centering
\subfloat[subfloat don't work, i want it to be Fig.1(b)]{\label{fig:2}\includegraphics[width=0.4\textwidth]{example-image-a}}
\end{figure}

\end{document}
