我想知道该geometry包当前是否支持以下页面尺寸设置：
这就是设置以下内容：
- 2=3（每项设置为1）；
- 5=6（每个设置为 4.6 毫米），以及
- 1=4（每个设置为 1 英寸）。
我尝试使用该命令\usepackage[ left=2.54cm, right=2.54cm, top=3cm, bottom=3cm, headheight = 3.5\baselineskip, headsep = 4.6mm, a4paper ]{geometry}，但似乎不起作用。我需要帮助。如果该软件包目前不支持指示的长度，我希望维护者 @David Carlisle 和 @Hideo Umeki 正在努力实现这一点。到目前为止，使用该layout软件包，我需要调整的长度不可用，如下图所示：
以下是我的 MWE：

\LaTeX{} hasmany symbols at its disposal. The majority of them are within the mathematical domain as shown in \eqref{eq:1} and \eqref{eq:2}. The ten special keyboard characters are: \verb|#|, \verb|$|, \verb|%|, \verb|&|, \verb|~|, \verb|_|, \verb|^|, \verb|\| and \verb|{}|. If you simply want the character to be printed just as any other letter, include a \verb|\ | in front of the character. For example, \verb|\$| will produce \verb|$| in your output.
The exception to the rule is the \verb|\ | itself because \verb|\\ | has its own special meaning. A \verb|\ | is produced by typing \verb|$\backslash$| in your file.

答案1
使用您的设置，我得到了非常正确的几何形状。您可以使用它\dimexpr来更精确地设置长度，因为您结合使用了英寸和毫米。
请注意，TeX 中的一点 (pt) 为 72.72 英寸，这可能与各种转换工具使用的点单位不同。
还要注意的是，TeX 内部使用 pt，因此其他单位的长度在某个时候都会被转换。如果你尝试将 pt 的长度重新转换为英寸，你可能会得到轻微的舍入误差。（但我想说，使用任何其他软件也会遇到这个问题。）
\documentclass[12pt,openany,twoside]{book}
\usepackage[
a4paper,
left=1in,
right=1in,
top=\dimexpr 1in + 4.6mm \relax,
bottom=\dimexpr 1in + 4.6mm \relax,
headsep=4.6mm,
headheight=3\baselineskip,
footskip=\dimexpr \baselineskip + 4.6mm \relax

\usepackage{layout}
\begin{document}
Text width should be 210mm $-$ 1in $-$ 1n.
\newlength{\testlength}
\setlength{\testlength}{\paperwidth}
\addtolength{\testlength}{-1in}
\addtolength{\testlength}{-1in}
This is about \the\testlength .
Text width is in fact \the\textwidth .

Text height should be 297mm $-$ 1in $-$ 4.6mm $-$ 1in $-$ 4.6mm.
