我正在尝试使用 lyx 制作希伯来语演示文稿。我尝试了 beamer，但效果不佳。然后我尝试了 powerdot，但当我编译文档 (ps2pdf) 时，没有显示希伯来语（空文档）。有人知道如何解决这个问题吗？或者还有其他方法可以用希伯来语创建演示文稿？我想使用的工具是 lyx，而不是 latex 编辑器。谢谢帮助！
这是我编译的文档（使用 ps2pdf），我得到了一个空的 pdf 文件：
\documentclass[english,hebrew]{powerdot}
\usepackage[T1]{fontenc}
\usepackage[cp1255]{inputenc}
\setlength{\parindent}{0bp}
\usepackage{babel}
\begin{document}
\title{דג}\maketitle
\end{document}
下面是我用 ps2pdf 编译的文件：
\lyxformat 474
