我正在使用 pdfTeX 将 TeX 文件转换为 PDF。TeX 文件由 Doxygen（版本 1.9.3）创建。我想减少 PDF 输出中的行距。
经过一番研究，我的结论是在 doxygen.sty 文件中的以下几行中进行更改：
\newcommand\doxysection{\@startsection {section}{1}{\z@}%
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
{\raggedright\normalfont\Large\bfseries}}
\newcommand\doxysubsection{\@startsection{subsection}{2}{\z@}%
{-3.25ex\@plus -1ex \@minus -.2ex}%
{1.5ex \@plus .2ex}%
{\raggedright\normalfont\large\bfseries}}
\newcommand\doxysubsubsection{\@startsection{subsubsection}{3}{\z@}%
{-3.25ex\@plus -1ex \@minus -.2ex}%
{1.5ex \@plus .2ex}%
{\raggedright\normalfont\normalsize\bfseries}}
\newcommand\doxyparagraph{\@startsection{paragraph}{4}{\z@}%
{3.25ex \@plus1ex \@minus.2ex}%
{-1em}%
{\raggedright\normalfont\normalsize\bfseries}}
\newcommand\doxysubparagraph{\@startsection{subparagraph}{5}{\parindent}%
{3.25ex \@plus1ex \@minus .2ex}%
{-1em}%
{\raggedright\normalfont\normalsize\bfseries}}
我不确定这是正确的解决方案，但我不明白以下含义：
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
以及如何改变它们以减少 PDF 中的行距。
这是我的代码

我想删除所有空行，例如 2.8.1 和 2.8.1.1 之间的空行
答案1
当我们在源代码上运行 doxygen 时，我们会看到相关部分（我将文件命名为 aa.cpp）：
\doxysubsection{Function Documentation}
\mbox{\Hypertarget{aa_8cpp_a0e828b455db64ea3b215dc1bc1cf7977}\label{aa_8cpp_a0e828b455db64ea3b215dc1bc1cf7977}}
\index{aa.cpp@{aa.cpp}!func1@{func1}}
\index{func1@{func1}!aa.cpp@{aa.cpp}}
\doxysubsubsection{\texorpdfstring{func1()}{func1()}}
看起来\mbox是在这种情况下这里没有必要，因为只需删除命令\mbox我们就会得到：
而不是以下版本\mbox：
由于\Hypertarget（定义为\newcommand{\Hypertarget}[1]{\Hy@raisedlink{\hypertarget{#1}{}}}）和\label只是锚点/标记，因此我认为\mbox这里没有必要。
