这就是我尝试在 overleaf-latex 中为图像添加标题的方法，但我收到“\caption 超出浮动范围”的错误。如何解决？

Question

\newpage

\onecolumn{\section{Proposed Model}} 

\vspace{5mm} %5mm vertical space

\begin{center}

    \includegraphics[scale=0.5]{flowchart}\\

    \caption{Image Encryption Flowchart}

\end{center}

Answer 1

您的标题确实不在浮动中。浮动环境由figure或创建table。

\usepackage{graphicx}

\begin{document}

\onecolumn{\section{Proposed Model}} 

\vspace{5mm}% 5mm vertical space

%\begin{center}
\begin{figure}[htb]
\centering
    \includegraphics[scale=0.5]{example-image}
    \caption{Image Encryption Flowchart}
\end{figure}
%\end{center}

\end{document}
