如何在将 tex 转换为 pdf 时设置边距和字体大小？

Question

我正在尝试将 Github 教程制作成 PDF 书https://github.com/redguardtoo/mastering-emacs-in-one-year-guide/blob/master/guide-en.org（以便在我的 iPad 上舒适地阅读）为此，我将 Emacs org 文件导出为 tex 文件，然后通过以下方式将其转换为 pdf：

$ pandoc -s emacs-in-one-year.tex -o emacs-in-one-year.pdf

转换后，PDF 看起来比例不合适，字体太小，文本四边留有空白。屏幕截图如下：https://i.hizliresim.com/kXdlp9.png

我在 Stackoverflow 上搜索了这个问题，并应用了建议的解决方案，但都没有奏效，边距仍然很大，字体很小。修改后的 tex 文件现在如下所示。我怎样才能使字体更大、边距更小？谢谢。

当我转换时

Answer 1

我已经编辑了您的示例，以便运行时不会出现错误，并且我认为您想要的边距（但这些边距是很多太小）。
