如何将“独立”的 TikZ 图像重新置于中心位置以转换为 png

Question

你想要这样的东西吗？

在此处输入图片描述

代码中的主要问题在最后一行

\draw (Z1)  -- (Z2) arc(-90:90:\dusttwo) (Z3) -- (Z4) arc(90:270:\dusttwo) (Z1) ;

半径\dusttwo太短，而不是20*\jay我使用的22*\jay（根据您的喜好进行调整）。您的命令绘制了两条路径，(Z1) -- (Z2) arc(-90:90:\dusttwo)后面跟着(Z3) -- (Z4) arc(90:270:\dusttwo) (Z1)。没有理由进行这样的划分，一条路径就足够了：

 \draw (Z1)  -- (Z2) arc(-90:90:22*\jay) coordinate (aux) -- (aux-|Z1) arc(90:270:22*\jay);

其他一些评论：

对于我来说，该代码无需\usepackage{calc}（不要将其与混淆\usetikzlibrary{calc}，这既不是也没有必要）就可以工作。

如果您使用standalone类来进行隔离，tikzpicture则没有必要\pagestyle{empty}，并且\noindent这会在最终结果中引入一点转变。

而且，如果你需要，你还可以引入一个border=...选项，在standalone剪辑结果之前会考虑该选项。我在这里没有用过，这只是信息。
