TIkZ-pic（带子图片）无法缩放

Question

我读过了从直角坐标转换为极坐标但没有找到适合我的解决方案。

我已经定义了一个pic名称compass，计划在不同的缩放版本中多次使用它（并以不同的角度旋转）。

我可以定义第二个pic名为 的元素yacht，它是可重新定位、可缩放和可旋转的。唯一的区别是，我使用极坐标来构建罗盘玫瑰。

以下是预期用途的示例文档：

\begin{tikzpicture}
  \node (a) {A} ;
  \path pic (b) at ([xshift=5cm] a) {yacht} ;
  \pic [below=2cm of a, scale=.4, rotate=220] (c) {yacht} ;
  \pic [scale=.2, rotate=120, right=2cm of c-yacht] (d) {yacht} ;
  \pic [below=8cm of d-yacht, scale=.2, rotate=60] (error) {compass} ;
  \pic [right=9cm of error-compass ] (error) {compass} ;
\end{tikzpicture}

（为了进行比较，第一次调用yacht未缩放且未旋转。）

这就是结果。

什么地方出了错？

这是完整的 MWE（我删除了的定义以yacht使其保持较小）。

Answer 1

\pic{compass}这是一个可以缩放和设计样式的（高尔夫类型）示例。

\documentclass[tikz,border=7pt]{standalone}
\tikzset{
  compass/.pic = {
    \foreach[count=\i,evaluate={\m=div(\i-1,4);\a=90*\i-45*(\m+1)}] \d in {NE,NW,SW,SE,E,N,W,S}{
      \filldraw[pic actions,rotate=\a,scale=.7+.3*\m] (0,0) -- (45:1)--(0:3) node[transform shape,rotate=-90,above]{\d};
      \filldraw[pic actions,fill=white,rotate=\a,scale=.7+.3*\m] (0,0) -- (-45:1)--(0:3)--cycle;
    };
  }
}
\begin{document}
  \begin{tikzpicture}
    \pic{compass};
    \pic[scale=.7,fill=red,text=blue] at (7,0) {compass};
  \end{tikzpicture}
\end{document}

Answer 2

正如@Kpym 在他的评论中所建议的那样，可以使用该选项transform canvas={scale=...}。

因此，

\begin{tikzpicture}
  \pic [scale=.2] (error) {compass} ;
  \pic [right=9cm of error-compass ] (full-size) {compass} ;
\end{tikzpicture}

你应该使用

\begin{tikzpicture}
  \pic [transform canvas={scale=.2}] (error) {compass} ;
  \pic [right=9cm of error-compass ] (full-size) {compass} ;
\end{tikzpicture}

这对我来说很有效，但它把放在了pic图片的中间。所以你还必须在 x 和 y 上添加一些校正动作！

Answer 3

您还可以使用\resizebox{width}{height}{what you want to resize}

这样，您就不会遇到与transform canvas={scale=...}周围环境有关的问题。
