我正在尝试从文件 bk10.clo 手动更改边距，我希望在双面模式下边距对称于 3cm，在单面模式下边距为顶部 = 3cm、左侧 = 4cm、右侧 = 2cm、底部 = 3cm。
这是我的代码但我认为它不正确。

\@settopoint\topmargin

提前致谢。
编辑： 使用
\makeatletter
\setlength{\oddsidemargin}{-1in}
\if@twoside
\addtolength{\oddsidemargin}{3cm}
\else
\addtolength{\oddsidemargin}{4cm}
\fi
\setlength{\evensidemargin}{\oddsidemargin}
\setlength{\textwidth}{\paperwidth}
\addtolength{\textwidth}{-6cm} % left+ right margins
\setlength{\topmargin}{-1in}
\addtolength{\topmargin}{-\headheight}
\addtolength{\topmargin}{-\headsep}
\addtolength{\topmargin}{3cm}
\setlength{\textheight}{\paperheight}
\addtolength{\textheight}{-6cm} % top + bottom margins
\makeatother
我感谢任何帮助...

尝试理解这一点
\makeatletter
\setlength{\oddsidemargin}{-1in}
\if@twoside
\addtolength{\oddsidemargin}{3cm}
\else
\addtolength{\oddsidemargin}{4cm}
\fi
\setlength{\evensidemargin}{\oddsidemargin}
\setlength{\textwidth}{\paperwidth}
\addtolength{\textwidth}{-6cm} % left+ right margins
\setlength{\topmargin}{-1in}
\addtolength{\topmargin}{-\headheight}
\addtolength{\topmargin}{-\headsep}
\addtolength{\topmargin}{3cm}
\setlength{\textheight}{\paperheight}
\addtolength{\textheight}{-6cm} % top + bottom margins
\makeatother
