這就是我嘗試在背面乳膠中為我的圖像添加標題的方式，但我收到了“\在浮動之外的標題”錯誤。如何解決呢？

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

您的標題確實不是浮動的。浮動環境由figure或創建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}
