这个问题涉及几何布局中 tikz 图片的居中。该问题结合了 tex.stackexchange 中回答的两个答案。
第一个答案解释了如何将 tikz 图片定位在页面的中心。但至少在这种情况下，它没有给出正确的结果。
第二个答案在循环中创建 tikz 图片。但它从猜测的值中计算出最重要的坐标(page cs:-0.5045,0.595)。
因此，tikz 图片不居中，并且打印两面时，差异显而易见。
问题是：如何将整个 tikz 图片水平和垂直居中在几何布局区域中？我不知道如何计算坐标。

答案1
这incgraph该包允许将内容置于页面中央。
因此，我补充说
\usepackage{incgraph}
并将图片封装到inctext环境中。
\igrset{currentpaper}
\begin{inctext}
\begin{tikzpicture}
\coordinate (A) at (page cs:-0.5045,0.595);
\coordinate (left) at (A);
