定心和参考坐标

问题 1我可以定义 x 和 y 的参考坐标，然后使用这些坐标来调整 Tikz 图片内的图形吗？

举例来说，如果我想将此图片中的所有矩形向左重新调整 0.25，我必须手动更改每个框或每个 \foreach 指令的坐标。请提供更好的解决方案。我可以在开始时定义坐标，例如 x = 0 和 y = 0，然后如果我必须重新调整矩形，我只需将 x 更改为 -0.25 并将 y 更改为 -0.25。

问题2我怎样才能将 tikzpicture 置于会议论文的一栏中央？

谢谢！

答案1

您可以使用calc：

\documentclass[tikz]{standalone}
\usetikzlibrary{positioning, calc}

\begin{document}

  \begin{tikzpicture}
    \coordinate (ref) at (0,0);
    \draw [rounded corners](ref) rectangle +(9,6);
    \draw [rounded corners]($(ref) + (0.15,0.5)$) node[above right, font =\small,align=center,text width = 2cm]{YYYY} rectangle +(2.25,5);
    \foreach \x in {2.5}
    \foreach \y in {0.5,3,4.5}
    {
      \draw [rounded corners] ($(ref) + (\x,\y)$) rectangle +(6.35,1);
    }
    \foreach \x in {2.75,4.25,5.75,7.25}
    \foreach \y in {0.9,3.4,4.9}
    {
      \draw [rounded corners] ($(ref) + (\x, \y)$) node[above right, font=\scriptsize,text width = 1.8cm] {XXX} rectangle +(1.2,0.5);
    }
    \coordinate (ref) at (-0.25,-0.25);
    \tikzset{color=red}
    \draw [rounded corners](ref) rectangle +(9,6);

    \draw [rounded corners]($(ref) + (0.15,0.5)$) node[above right, font =\small,align=center,text width = 2cm]{YYYY} rectangle +(2.25,5);
    \foreach \x in {2.5}
    \foreach \y in {0.5,3,4.5}
    {
      \draw [rounded corners] ($(ref) + (\x,\y)$) rectangle +(6.35,1);

    }
    \foreach \x in {2.75,4.25,5.75,7.25}
    \foreach \y in {0.9,3.4,4.9}
    {
      \draw [rounded corners] ($(ref) + (\x, \y)$) node[above right, font=\scriptsize,text width = 1.8cm] {XXX} rectangle +(1.2,0.5);
    }
  \end{tikzpicture}

\end{document}

使用 <code>calc</code> 进行移位迭代
