如何制作这种格式的投影仪模板？

Question

我正在尝试将 \documentclass{article} 转换为 \documentclass{beamer}，但保留结构。上图是我使用 article 类得到的结果。

这正是我想要的，但是由于它不在 beamer 类中，所以我无法用它做太多事情...我用来生成它的代码如下所示。

\documentclass{article}
\usepackage{amsmath}
\usepackage{color,pxfonts,fix-cm}
\usepackage{latexsym}
\usepackage[mathletters]{ucs}
\usepackage[T1]{fontenc}
\usepackage[utf8x]{inputenc}
\usepackage{pict2e}
\usepackage{wasysym}
\usepackage[english]{babel}
\usepackage{tikz}
\pagestyle{empty}
\usepackage[margin=0in,paperwidth=720pt,paperheight=405pt]{geometry}
\begin{document}
 \definecolor{color_283006}{rgb}{1,1,1}
 \definecolor{color_29791}{rgb}{0,0,0}
 \definecolor{color_118168}{rgb}{0.34902,0.34902,0.34902}
 \begin{tikzpicture}[overlay]
  \path(0pt,0pt);
  \filldraw[color_283006][even odd rule]
  (-15pt, 10pt) -- (682.5pt, 10pt)
  -- (682.5pt, 10pt)
  -- (682.5pt, -382.3438pt)
  -- (682.5pt, -382.3438pt)
  -- (-15pt, -382.3438pt) -- cycle
  ;
 \draw[color_29791,line width=0.726563pt,line join=round]
(247.3314pt, 6.594879pt) -- (659.7076pt, 6.594879pt)

-- (659.7076pt, -47.85956pt)

;
\end{tikzpicture}

我的想法是使用上面的代码来配置标题并对框架执行相同的操作，但我不习惯投影仪......

如果有人有想法，我将不胜感激！提前致谢。
