如何显示文本/公式中的所有边距、框架和间距？

下面的 MWE 显示了边距框架。这很酷，但对我来说还不够。我想显示文本行和方程式周围的间距（上下跳过等）。这可能吗？是否有显示所有垂直间距的选项或包？

\documentclass[11pt,letterpaper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage[nomath]{lmodern}
\usepackage[total={6in,10in},left=1.5in,top=0.5in,includehead,includefoot,showframe]{geometry}
\usepackage[nodisplayskipstretch]{setspace}
\setstretch{1.1}
\raggedbottom
\usepackage{microtype}
\usepackage{nccmath,amsmath}

\begin{document}

\setlength{\abovedisplayskip}{2ex}
\setlength{\abovedisplayshortskip}{0pt}
\setlength{\belowdisplayskip}{\abovedisplayskip}
\setlength{\belowdisplayshortskip}{\belowdisplayskip}
\setlength{\jot}{3ex}

This is just a test, to see what will happen next and the equation below this dummy text sample:
\begin{align}
    y^2 + x^2 - z^2 = 1
\end{align}

\end{document}

答案1

你可以加

\usepackage{lua-visual-debug}

然后使用 lualatex 然后你得到

在此处输入图片描述

但实际上调试文本表示比调试视觉表示更容易，所以我会添加\showoutputpdflatex 来获得：
