![如何在标题和图形之间插入适当量的垂直空间?](https://linux22.com/image/243103/%E5%A6%82%E4%BD%95%E5%9C%A8%E6%A0%87%E9%A2%98%E5%92%8C%E5%9B%BE%E5%BD%A2%E4%B9%8B%E9%97%B4%E6%8F%92%E5%85%A5%E9%80%82%E5%BD%93%E9%87%8F%E7%9A%84%E5%9E%82%E7%9B%B4%E7%A9%BA%E9%97%B4%EF%BC%9F.png)
在我的源文档中,我有一个图像和一个代码列表,中间由一些文本隔开。当我使用 pdflatex 生成 PDF 时,图像就在列表上方,看起来图像的标题就是列表的标题,即图像的标题离列表比离图像更近。这是我可以重现问题的最短示例。

下图显示了上述源代码的输出。在我的完整文档中,第一个标题和代码列表之间的距离更小。如何在第一个标题和第二个图之间插入更多空间(视情况而定)?根据中间的编辑,这两个图可能会或可能不会出现在同一页上。
答案1
您可以根据需要修改长度\floatsep
,它指定页面顶部/底部浮动之间的垂直距离/长度。通过“适当”,您可以排版文档,只需在最后担心这种(手动)微调。
以下最小示例显示了两个重复的页面,除了修改以\floatsep
显示修改浮动分离的效果之外。
\documentclass{article}
\usepackage[demo]{graphicx}% http://ctan.org/pkg/graphicx
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\begin{document}
\lipsum[1]
\begin{figure}[t]
\centering \includegraphics{figure1}
\caption{This is a figure}
\end{figure}
\begin{figure}[t]
\centering \includegraphics{figure2}
\caption{This is another figure}
\end{figure}
\lipsum[2]
\clearpage
\setlength{\floatsep}{1pt}

来自layouts
包裹 文档可以根据页面/文档浮动元素查看长度(第 21 页及以后):
默认值为 ,12.0pt plus 2.0pt minus 2.0pt
允许2pt
从 进行拉伸12pt
。
也可以skip
使用caption
包裹. 默认为10pt
