使用几何技术在奇数/偶数页上设置不同的内/外边距

Question

我正在尝试排版一本书（实际上是一本字典），但一直无法在偶数页和奇数页上设置相等的内边距和外边距。我以前做过很多次，但这次要么是 Geometry 忽略了我的参数，要么是发生了其他事情。

如果您能提供一些启发，我将不胜感激……

代码如下（不是完整的源代码）：

\documentclass[6pt,twoside]{scrbook}

\usepackage[paperwidth=4.125in, 
            paperheight=6.25in, 
            bindingoffset=0.2in,
            inner=1.0in,
            outer=0.5in,
            top=0.4in,
            bottom=0.75in,
            columnsep=20pt,
            layoutsize={4in,6in},
            layouthoffset=0.125in,
            layoutvoffset=0.25in,
            showcrop=true,
            showframe=true
            ]
            {geometry}

结果如下所示（我显然希望奇数页的外边距更大 - 内边距也相应更小 - 这样所有内容都可以很好地适应）

PS 以防万一，源代码正在编译xelatex。如果您需要查看更多代码，请告诉我！;)

以下给出了奇数页和偶数页之间的对称布局：

\documentclass[fontsize=6pt,twoside]{scrbook}

\usepackage[paperwidth=4.125in,
            paperheight=6.25in,
            %bindingoffset=0.2in, %  <----------- commented out
            inner=1.0in,
            outer=1.0in,          %  <----------- same as inner
            top=0.4in,
            bottom=0.75in,
            columnsep=20pt,
            layoutsize={4in,6in},
            layouthoffset=0.125in,
            layoutvoffset=0.25in,
            showcrop=true,
            showframe=true
            ]
            {geometry}

% You can also use this to visualize the layout:
% \usepackage{showframe}
% \renewcommand\ShowFrameLinethickness{0.15pt}
% \renewcommand*\ShowFrameColor{\color{blue!30!white}}

\begin{document}

注意：看到 KOMA-Script 警告后，我将您的6pt \documentclass选项替换为fontsize=6pt。
