我正在为我的学生设计一款记忆卡游戏，并设置了一个 6cm x 6cm 的卡片网格，如下所示：
问题是我不太会用这台切割机，总是会错过线条。所以我想在所有与网格线对齐的边框上添加切割标记。这样我就可以稍微切割一下，看看它是否在正确的位置。
网格生成如下所述：https://newbedev.com/foreach-loop-inside-the-tikz-picture-creation-of-memory-cards-using-tikz我只做了一点调整，所以在我看来它看起来是这样的：
%%% Global Setup
\newcommand\xspacing{86pt}%<== space between the images
\newcommand\yspacing{86pt}%<== vertical space between rows
\newcommand\imgperrow{4}%<== number of images per row
%%% Define primary for loop
\newcommand{\forloop}[2]{%
\foreach [count=\i] \x in {#1,...,#2}%<==loop for each image in the array
{
\edef\gonode{\noexpand\node[inner sep=0pt] (B) at (A) {\noexpand\includegraphics[width=6cm]{\getimage{\x}}};}%<==Edit to expand the file name
\gonode%
\draw [black, ultra thick] ($(B.north west)$) rectangle ($(B.south east)$);%
\pgfmathparse{Mod(\i,\imgperrow)==0?1:0};%
\ifnum\pgfmathresult>0
\coordinate (left) at ([yshift=-\yspacing]left);
\path let \p1=(left),\p2=(B.south) in coordinate (A) at (\x1,\y2-\yspacing);
\else
\coordinate (A) at ([xshift=\xspacing]B.east);%
\fi
}}
\begin{document}
\pagestyle{empty}
%first page
\begin{tikzpicture}[remember picture, overlay]
\coordinate (A) at (page cs:-0.5045,0.595);
\coordinate (left) at (A);
\forloop{1}{24}
\end{tikzpicture}
\end{document}
现在我有点迷茫，不知道是否可以访问网格线（实际上是矩形，正如您从代码中看到的那样）的坐标并在这些位置的边框上放置切割标记。
附录：这是完整的代码。我尝试删除不必要的部分。

答案1
我感觉你的代码有点复杂。无论如何，我不会使用提供的裁剪标记，geometry而只是使用 Ti 绘制自定义的裁剪标记钾Z.下面的代码希望能够帮助您。
我删除了原始代码的大部分内容，因为我认为它们对于您的具体示例来说是不必要的。我定义了四个包含不同维度的新宏，即\shiftright、\shiftdown和。\imgwidth\imgheight
我最终定义了一个新的宏\cropmarks，它接受两个参数，即列数和行数，并打印出每行和每列之间的裁剪标记。我希望这就是你想要的。
