如何避免或补偿 tikz 删除节点中的水平和垂直偏移？

Question

下面的 MCE 指出，对于tikz' 删除节点， line width会导致水平和垂直移动。是否有可能

• 避免它们？
• 或者，至少，要准确地知道这些转变的程度，以便对其进行补偿（删除的文本与“正常”文本位于同一位置）？

这个问题与如何避免“删除”内容的转变（来自 tikz shapes.misc 库）？但反过来：在这里，我希望“正常”文本不是被删除的文本将被移动，但被删除的文本将被不是被转移并且处于与“正常”位置相同的位置。

\documentclass{article}
\usepackage[arrows=false]{pagegrid}
\usepackage[margin=0cm,papersize=2cm]{geometry}
\usepackage{tikz}
\usetikzlibrary{shapes}
%
\setlength{\parindent}{0pt}
%
\newcommand{\test}[1][]{%
  \tikz \node [draw,inner sep=0pt,outer sep=0pt,strike out,draw=red,#1] {%
    test%
  };%
}
%
\begin{document}
test \test{} \test[line width=.5ex]

\test{} \test[line width=.5ex] test

\test[line width=.5ex] test \test{}
\end{document}

Answer 1

如果我理解正确的话，您也许可以将打击绘制为一个单独的节点（使用库fit来获取正确的大小），并将overlay选项添加到该节点，这样它就不会被考虑用于边界框的计算。

\documentclass{article}
\usepackage[arrows=false]{pagegrid}
\usepackage[margin=0cm,papersize=2cm]{geometry}
\usepackage{tikz}
\usetikzlibrary{shapes,fit} % <-- added fit
%
\setlength{\parindent}{0pt}
%
\newcommand{\test}[1][]{%
\begin{tikzpicture}
% first add text
\node [inner sep=0pt,outer sep=0pt] (foo) {test};
% draw strike out in separate node, with overlay option
\node [overlay,inner sep=0pt,fit=(foo),strike out,draw=red,#1] {};
\end{tikzpicture}%
}
%
\begin{document}
test \test{} \test[line width=.5ex]

\test{} \test[line width=.5ex] test

\test[line width=.5ex] test \test{}
\end{document} 

Answer 2

使用 tikz创建自己的命令非常容易strike out。只需使用[remember picture,overlay]tikz 环境的选项即可避免干扰文本。

\documentclass{article}
\usepackage[arrows=false]{pagegrid}
\usepackage[margin=0cm,papersize=2cm]{geometry}
\usepackage{tikz,calc}
\usetikzlibrary{shapes}
%
\setlength{\parindent}{0pt}
%
\newlength\teht
\settoheight\teht{t}
\newcommand\tikzmark[1]{\tikz[remember picture,overlay]\coordinate(#1);}

\newcommand{\test}[2][]{%
  \tikzmark{o}#2\tikzmark{a}%
  \tikz[remember picture, overlay]{\draw[red,#1](o)--([yshift=\teht]a);}%
} 
\begin{document}    
test \test{test} \test[line width=.5ex]{test}

\test{test} \test[line width=.5ex]{test} test

\test{test} test \test[line width=.5ex]{test}    
\end{document}

有人问过一个几乎相同的问题这里我只是在回收这个答案。
