自动将子图拆分到多页

我有很多子图，我想将它们拆分到多个页面中。这些子图的大小不同。我仍在编辑文档，因此图被推来推去。我不想硬性规定子图之间的分页符在哪里。

我怎么能够：

  1. 当前页面已满时是否自动获取子图来开始新页面？
  2. 仅在开始新页面时添加标题？
  3. 防止其他内容在子图之间移动？

以下是我当前文档的一个示例。如您所见，\ContinueFloat 是硬连线的。其他内容位于前 5 个子图和后 5 个子图之间。

\begin{figure}
\centering
\subfloat[]{\label{fig:1}\includegraphics[width=0.43\textwidth]{fig1}}
\qquad
\subfloat[]{\label{fig:2}\includegraphics[width=0.43\textwidth]{fig2}}
\subfloat[]{\label{fig:1}\includegraphics[width=0.43\textwidth]{fig1}}
\qquad
\subfloat[]{\label{fig:2}\includegraphics[width=0.43\textwidth]{fig2}}
\qquad
\subfloat[]{\label{fig:1}\includegraphics[width=0.43\textwidth]{fig1}}
\qquad
\caption{Here are the first 5 figures of a continued figure.}
\label{fig:cont}
\end{figure}

\begin{figure}
\ContinuedFloat
\centering
\subfloat[]{\label{fig:1}\includegraphics[width=0.43\textwidth]{fig1}}
\qquad
\subfloat[]{\label{fig:2}\includegraphics[width=0.43\textwidth]{fig2}}
\qquad
\subfloat[]{\label{fig:1}\includegraphics[width=0.43\textwidth]{fig1}}
\qquad
\subfloat[]{\label{fig:2}\includegraphics[width=0.43\textwidth]{fig2}}
\qquad
\subfloat[]{\label{fig:1}\includegraphics[width=0.43\textwidth]{fig1}}
\caption{Here are the last 5 figures of a continued figure.}
\label{fig:cont}
\end{figure}

有趣的是，\subfloat似乎以 结尾\ignorespaces，因此您要么需要一个空白行，\allowbreak要么需要其他允许换行的内容。所有子浮点数都是一次性格式化的，因此\ContinuedFloat不需要。

我可以使用 udbox 将其转变为一个环境（参见https://tex.stackexchange.com/questions/563109/render-captions-above-figures-with-caption-below-includegraphics-while-using-e/563241?r=SearchResults&s=2|22.2526#563241）。
