定义 2 面、双面的不同边距

Question

您可以使用命令\newgeometry和\restoregeometry（和\savegeometry）几何学包裹。

但你有一个twoside文档并且处于双面模式几何学将交换背面页面的左右边距。

您可能不希望将其与文档的最后一页交换，因为这意味着对于文档的最后一页，您无法预测左边距是 4 厘米而右边距是 6 厘米，还是左边距是 6 厘米而右边距是 4 厘米，因为这取决于文档最后一页的数字奇偶性。

因此，我建议“手动” 设置第一页和最后一页的 LaTeX 参数\oddsidemargin和等。\evensidemargin

确保这些设置在本地范围/组内进行。

不要使用 LaTeX 命令\setlength等\addtolength，因为这些命令的分配在任何情况下都是全局的。而是使用纯 TeX 语法。

这是一个小例子。

我改变了几何中的边距，以便您可以看到第一页和最后一页的边距有所不同。

如果你对如何“手动”调整边距感兴趣，而不使用几何学-包，布局-package 可能是您的信息来源。
