如何使用循环宏简化我的代码？

Question

\documentclass{article}
\usepackage{pstricks,multido}

\begin{document}
\begin{pspicture}

 \pswedge(0,0){2}{0}{15}
 \pswedge*(0,0){2}{15}{30}
  \pswedge(0,0){2}{30}{45}
 \pswedge*(0,0){2}{45}{60}

 \pswedge(0,0){2}{60}{75}
 \pswedge*(0,0){2}{75}{90}
  \pswedge(0,0){2}{90}{105}
 \pswedge*(0,0){2}{105}{120}

  \pswedge(0,0){2}{120}{135}
 \pswedge*(0,0){2}{135}{150}
  \pswedge(0,0){2}{150}{165}
 \pswedge*(0,0){2}{165}{180}

  \pswedge(0,0){2}{180}{195}
 \pswedge*(0,0){2}{195}{210}
  \pswedge(0,0){2}{210}{225}
 \pswedge*(0,0){2}{225}{240}

 \pswedge(0,0){2}{240}{255}
 \pswedge*(0,0){2}{255}{270}
  \pswedge(0,0){2}{270}{285}
 \pswedge*(0,0){2}{285}{300}

 \pswedge(0,0){2}{300}{315}
 \pswedge*(0,0){2}{315}{330}
  \pswedge(0,0){2}{330}{345}
 \pswedge*(0,0){2}{345}{360}

\end{pspicture}
\end{document} 

Answer 1

\foreachfrompgffor包在 PSTricks 中也是默认可用的。因此，你不需要使用\multido。

\documentclass[pstricks,preview,margin=5mm]{standalone}

\begin{document}
\begin{pspicture}(-2,-2)(2,2)
\foreach \i [evaluate = \i as \j using \i+15] in {0,30,..., 330}{\pswedge*{2}{\i}{\j}}
\end{pspicture}
\end{document}

输出与其他答案完全相同。

Answer 2

\documentclass[pstricks,preview,margin=5mm]{standalone}
\usepackage{multido}

\def\obj#1{%
    \begin{pspicture}(-2,-2)(2,2)
        \multido{\i=#1+30}{12}{\rput{\i}(0,0){\pswedge*(0,0){2}{0}{15}}}
    \end{pspicture}%
}

\begin{document}
\obj{0}\obj{15}%
\end{document}

注意：星号\pswedge不需要linestyle=none,linewidth=0删除轮廓，因为它已经自动完成了。

Answer 3

\documentclass{article}

\usepackage{pstricks,multido}

\begin{document}

\begin{pspicture}
  \multido{\i=0+15}{24}{%
    \def\dowedge{\pswedge}%
    \ifodd\i\def\dowedge{\pswedge*}\fi
    \dowedge(0,0){2}{\i}{\number\numexpr\i+15}%
  }
\end{pspicture}

\end{document}

也许还可以绘制一个填充黑色的圆圈并插入 12 个白色楔子。

---

作为次要请求，您可以将 设置linestyle为none，这将删除外圆以及“内点”。实际上，这样就不需要打印白色楔形了，从而使代码更轻便一些：

\documentclass{article}

\usepackage{pstricks,multido}

\begin{document}

\begin{pspicture}
  \multido{\i=0+30}{12}{%
    \pswedge*(0,0){2}{\i}{\number\numexpr\i+15}%
  }
\end{pspicture}

\end{document}

Answer 4

首先定义一个 24 度的圆。这样事情就简单多了：

\documentclass{article}
\usepackage{pstricks,multido}
\begin{document}

\begin{pspicture}
\degrees[24]
\multido{\i=0+2}{12}{\pswedge*{2}{\i}{!\i\space 1 add}}
\end{pspicture}

\end{document}
