我遇到的问题是，我的输出 pdf 的左右边距不正确。您可以在下图中看到它：
问题是，我需要相反的方法。左边要宽，右边要窄。我该如何改变这种情况？
以下是模板的配置：
\geometry{%
%%% Paper size
a4paper, % Andere a0paper, a1paper, a2paper, a3paper, , a5paper, a6paper,
% b0paper, b1paper, b2paper, b3paper, b4paper, b5paper, b6paper
% letterpaper, executivepaper, legalpaper
portrait, % Hochformat
lines=45, % enables users to specify \textheight by the number of lines
ignoreall, % sets both ignoreheadfoot and ignoremp to true
heightrounded, % This option rounds \textheight to n-times (n: an integer) of \baselineskip
twoside, % switches on twoside mode with left and right margins swapped on verso pages.
bindingoffset=5mm, % removes a specified space for binding
marginparwidth=0pt, % width of the marginal notes
textwidth=400pt, % sets \textwidth directly
}
我发现了 typearea 的定义，它是自动使用的：
\KOMAoptions{% (most options are for package typearea)
twoside=true, % two side layout (alternating margins, standard in books)
twocolumn=false, % (true)
headinclude=false,%
footinclude=false,%
mpinclude=false,%
headlines=2.1,%
headsepline=true,%
footsepline=false,%
parskip=half+,% false(default=1em indent),full[-+*], half[-+*]
cleardoublepage=empty %plain, headings
}%
