我使用 TikZ 制作书籍封面的方法是获取封面（书籍）的 4 个坐标，然后使用 TikZ 命令在 ABCD 内部自由绘图。
我们可以对 Asymptote 做类似的事情吗，即获取封面的 4 个坐标并在 Asymptote 代码中使用它们？
例如下面是我重绘的封面图片和最后的 TikZ 代码。我尝试使用 Asymptote 进行一些操作，但没有达到预期的效果。
\documentclass{book}
%\usepackage[top=2cm,bottom=2cm,left=2cm,right=1.5cm]{geometry}
\usepackage[inline]{asymptote}
\begin{document}
\begin{asy}
unitsize(1cm);
pair A=(current page.north west);
pair B=(current page.north east);
pair C=(current page.south east);
pair D=(current page.south west);
pair E=(current page.center);
draw(A--C,blue);
draw(B--D,red);
\end{asy}
\end{document}
PS：我寻找 Asymptote 方法的原因是：即使在 2D 中，Asymptote 也比 TikZ 更好，例如，在绘制隐函数图形方面。我想利用 Asymptote 的出色功能。

答案1
开始时很复杂，经过多次反复尝试才得到一个简化的结果，但现在你终于可以得到它了。
PS 需要 2 x pdfLaTeX、1 x Asy、另外 2 x pdfLaTeX。
