`doublespacing` 环境应用于印刷属性

Question

我正在处理一个 tex 文件来构建个人模板。就标题而言，我将增加标题行之间的间距。因此，只需尝试使用setspace包和doublespacing环境，如下所示：

\documentclass[•]{article}

\usepackage{amsfonts}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage{setspace}
\usepackage
[
        a4paper,% other options: a3paper, a5paper, etc
        left=2cm,
        right=2cm,
        top=3cm,
        bottom=4cm,
        vmargin=2cm,
        % use vmargin=2cm to make vertical margins equal to 2cm.
        % us  hmargin=3cm to make horizontal margins equal to 3cm.
        % use margin=3cm to make all margins  equal to 3cm.
]
{geometry}

\begin{document}

\begin{center}

\begin{doublespacing}

    \textbf{\Huge{the title of the template, is which supposed to include a long succession of characters and be splitted into different lines.}}   

\end{doublespacing}

\end{center}

\end{document}

但，预想的结果并没有出现，空间依旧如旧……

将这种环境应用到粗体和大段文本上有什么问题？...

Answer 1

你不需要setspace这个。

\documentclass{article}

\usepackage{amsfonts}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage[
  a4paper,% other options: a3paper, a5paper, etc
  left=2cm,
  right=2cm,
  top=3cm,
  bottom=4cm,
  %vmargin=2cm, %% What for? You already set top and bottom
]{geometry}

\begin{document}

\begin{center}
\linespread{1.5}\Huge\bfseries

The title of the template, is which supposed to
include a long succession of characters and be
split into different lines.
\end{center}

\end{document}

自行决定要传递的值\linespread。

我没有展示结果，因为它太糟糕了。

你的错误是什么？首先，环境被调用doublespace。其次，标题是\Huge双倍行距，但是，由于在段落分成行之前结束了 的效果，\doublespacing因此使用正常的基线跳过（但由于 而加倍）。

注意：\Huge其他大小声明不是带有参数的命令，并且段落必须在声明的范围内结束。因此

\begin{doublespace}
\centering
\bfseries\Huge

The long title

\end{doublespace}

可以完成这项工作。但这就像用枪来打蚊子一样。

删除所有括号并使用正确的环境名称：

\documentclass[•]{article}

\usepackage{amsfonts}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage{setspace}
\usepackage
[
        a4paper,% other options: a3paper, a5paper, etc
        left=2cm,
        right=2cm,
        top=3cm,
        bottom=4cm,
        vmargin=2cm,
        % use vmargin=2cm to make vertical margins equal to 2cm.
        % us hmargin=3cm to make horizontal margins equal to 3cm.
        % use margin=3cm to make all margins equal to 3cm.
]
{geometry}

\begin{document}


\begin{doublespace}
\centering

   \bfseries\Huge the title of the template, is which supposed to include a long succession of characters and be split into different lines.

\end{doublespace}

\end{document}
