独立于文本旋转自定义形状

我已经使用构建了一个自定义形状pdfdeclareshape，并在下图中使用它

截屏

我想独立于文本旋转边框，以便理想情况下它最终看起来像图像中的这个问题。

研究了pgf手册和如何在 Tikz 中独立旋转节点和文本（例如），我认为我应该使用shape border rotate，但并非所有形状都默认支持它。

我的自定义形状的边框可以独立于其文本旋转吗？（如果我的自定义形状可以改进，请随时批评。）

您可以使用shape border rotate某些形状存在的 （或定义您自己的特殊petal rotate键）。但是，当您定义新形状时，您必须自己完成所有工作。绘制形状边框很简单，但您可能希望/必须手动定义锚点以反映此键中的值（此处未完成）：

\documentclass[tikz]{standalone}

\makeatletter
\pgfkeys{/pgf/shape border rotate/.initial=0}

\pgfdeclareshape{petal}
{
    \inheritsavedanchors[from=circle] % this is nearly a circle
    \inheritanchorborder[from=circle]
    \inheritanchor[from=circle]{center}
    \inheritanchor[from=circle]{base}
    \savedmacro\petalparameters{%
      \pgfmathsetmacro\shapeborderrotate{\pgfkeysvalueof{/pgf/shape border rotate}}%
      \addtosavedmacro\shapeborderrotate%
    }
    \backgroundpath{
      % origin
      \petalparameters%
      {% Make sure transformations are  inside group.
         \pgftransformshift{\centerpoint}%
        \pgftransformrotate{\shapeborderrotate}%
        \pgfutil@tempdima=\radius%
        \pgfpathmoveto{\pgfqpoint{\pgfutil@tempdima}{0pt}}%
        \pgfpatharc{0}{180}{\pgfutil@tempdima}%
        \pgfpathcurveto{\pgfqpoint{-\pgfutil@tempdima}{-.5\pgfutil@tempdima}}%
          {\pgfqpoint{-.5\pgfutil@tempdima}{-.75\pgfutil@tempdima}}%
          {\pgfqpoint{0pt}{-1.5\pgfutil@tempdima}}
        \pgfpathcurveto{\pgfqpoint{0pt}{-.75\pgfutil@tempdima}}%
          {\pgfqpoint{\pgfutil@tempdima}{-.75\pgfutil@tempdima}}%
          {\pgfqpoint{\pgfutil@tempdima}{0pt}}%
      }%
   }
}
\makeatother

\begin{document}
\begin{tikzpicture}
    \foreach \i in {1,2,...,5}
    {
        \pgfmathparse{90-(\i-1)*360/5}
        \node[draw=black,anchor=base,shape border rotate=-(\i-1)*360/5,petal,minimum width=1.5cm] at (\pgfmathresult:1.25cm)  {\i};
    }
\end{tikzpicture}

使用 PSTricks。

\documentclass[pstricks,border=12pt]{standalone}
\usepackage{multido}
\psset{linejoin=1}
\SpecialCoor
\def\atom#1%
{
    \psccurve(0,0)(.3,.5)(1,1)(1,1.5)(0,2)(-1,1.5)(-1,1)
    \rput{*0}(0,1){#1}
}

\begin{document}
\begin{pspicture}[showgrid=false](-3,-3)(3,3)
    \multido{\ia=90+-72,\ib=0+-72,\in=1+1}{5}{\rput(.5;\ia){\rput{\ib}(0,0){\atom{\in}}}}
\end{pspicture}
\end{document}
