使用 tikz 繪製印度國旗

我正在嘗試使用以下想法繪製印度國旗這裡和其他包括阿肖克脈輪符號背頁範例。我想要使​​用正確的編碼和正確的尺寸，參見維基百科。我對阿肖克脈輪的大小有疑問。請任何人幫助我！我的 MWE 如下：

\documentclass[tikz]{standalone}


\definecolor{saffron}{HTML}{FF9933} % top stripe
\definecolor{white}{HTML}{FFFFFF} % middle stripe
\definecolor{indiegreen}{HTML}{138808} % bottom stripe
\definecolor{navyblue}{HTML}{000080} % ashok chakra

\tikzstyle{bharat}=[draw=navyblue,fill=navyblue]

\begin{document}
\begin{tikzpicture}
    \fill[saffron] (0,400mm) rectangle (900mm,600mm);
    \fill[white] (0,200mm) rectangle (900mm,400mm);
    \fill[indiegreen] (0,0) rectangle (900mm,200mm);
    \node at (450mm,300mm)[scale=0.09]{%
    \begin{tikzpicture}
        \draw[bharat, even odd rule] (0,0) circle (92.5) (0,0) circle (80); 
        \draw[bharat] (0,0) circle (16);
        \foreach \x in {0,..., 23}{
            \draw[bharat] (7.5+15*\x:80) circle (3.5); 
            \draw[bharat, rotate=15*\x] (0,0)--(5.38:32)--(80,0)--(-5.38:32)--cycle; 
        }
    \end{tikzpicture}
    };
\end{tikzpicture}
\end{document}

要強制執行九種不同的測量，可以使用.is choice該pgfkeys材料中的密鑰處理程序。我已經重新實現了標誌代碼（可能需要更多的修改才能使阿育王脈輪的細節完全正確）。請注意，對於較大尺寸的標誌，需要更改x和向量以避免錯誤：ydimension too large

\documentclass[tikz,border=5]{standalone}
\definecolor{saffron}{HTML}{FF9933}
\definecolor{white}{HTML}{FFFFFF}
\definecolor{indiegreen}{HTML}{138808}
\definecolor{navyblue}{HTML}{000080}
\tikzset{%
  flag width/.store in=\flagwidth,
  flag height/.store in=\flagheight,
  flag size/.style args={#1x#2}{flag width=#1, flag height=#2},
  Ashoka Chakra/.store in=\AshokaChakra,
  size/.is choice,
  size/.cd,
    1/.style={flag size=6300x4200, Ashoka Chakra=1295},
    2/.style={flag size=3600x2400, Ashoka Chakra=740},
    3/.style={flag size=2700x1800, Ashoka Chakra=555},

    8/.style={flag size=225x150, Ashoka Chakra=40},
    9/.style={flag size=150x100, Ashoka Chakra=25},
  /tikz/.cd,
  Flag of India/.pic={%

    \foreach \stripecolor [count=\i from 0] in {indiegreen, white, saffron}
      \path [fill=\stripecolor]
      (-\flagwidth/2, \i/3*\flagheight-\flagheight/2)
      rectangle ++(\flagwidth, 1/3*\flagheight);
    \tikzset{scale=\AshokaChakra/2}
    \path [fill=navyblue, even odd rule]
      circle [radius=1] circle [radius=22/25] circle [radius=1/5];
    \foreach \i in {0,...,23}

    {Flag of India={size=\size, shift=(270:\flagheight*3/4)}};
\end{tikzpicture}

你還有更多的問題：

  • 放入pic自己的tikzpicture方法是錯的
  • 由於scalebox您需要pic使用座標乘以比例因子的倒數。

\documentclass[tikz, border=3mm]{standalone}

\definecolor{saffron}{HTML}{FF9933} % top stripe
\definecolor{white}{HTML}{FFFFFF} % middle stripe
\definecolor{indiegreen}{HTML}{138808} % bottom stripe
\definecolor{navyblue}{HTML}{000080} % ashok chakra


\tikzset{
    estilo/.style = {draw=navyblue,fill=navyblue},% moved here
  ashokchakra/.pic ={
\scalebox{0.1}{
%\begin{tikzpicture} % <-- had to be deleted
    \draw[estilo, even odd rule] (0,0) circle (92.5) (0,0) circle (80);
    \draw[estilo] (0,0) circle (16);
    \foreach \x in {0,..., 23}{
        \draw[estilo] (7.5+15*\x:80) circle (3.5);
        \draw[estilo, rotate=15*\x] (0,0)--(5.38:32)--(80,0)--(-5.38:32)--cycle;
    \node{ \tikzpictext};
    }
%\end{tikzpicture} % <-- had to be deleted
}}}

\begin{document}
\begin{tikzpicture}
    \fill[saffron]      (0,40) rectangle (90,60);
    \fill[white]        (0,20) rectangle (90,40);
    \fill[indiegreen]   (0, 0) rectangle (90,20);
    \pic at (450,300) {ashokchakra};% <-- since you use scalebox
\end{tikzpicture}
\end{document}

scalebox如果您不使用並手動縮放圖中的所有座標，您將獲得更好的結果pic：

\documentclass[tikz, border=3mm]{standalone}
\definecolor{saffron}{HTML}{FF9933} % top stripe
\definecolor{white}{HTML}{FFFFFF} % middle stripe
\definecolor{indiegreen}{HTML}{138808} % bottom stripe
\definecolor{navyblue}{HTML}{000080} % ashok chakra

\begin{document}
\begin{tikzpicture}[
    estilo/.style = {draw=navyblue,fill=navyblue},% moved here
  ashokchakra/.pic ={
    \draw[estilo, even odd rule] (0,0) circle (9.25) (0,0) circle (8);
    \draw[estilo] (0,0) circle (1.6);
    \foreach \x in {0,..., 23}
    {
    \draw[estilo] (0.75+15*\x:8.0) circle (0.35);
    \draw[estilo, rotate=15*\x] (0,0)--(0.538:3.2)--(8.0,0)--(-5.38:3.2)--cycle;
    }
    }%end of pic
                ]
    \fill[saffron]      (0,40) rectangle (90,60);
    \fill[white]        (0,20) rectangle (90,40);
    \fill[indiegreen]   (0, 0) rectangle (90,20);
    \pic at (45,30) {ashokchakra};% <-- since you use scalebox
\end{tikzpicture}
\end{document}

在上面的 MWE 中，樣式ashokchakra被移入tikzpicture

受到此處解決方案之一的啟發，沒有嵌套，tikzpicture並且對輪子進行了輕微的更改。伸縮性也很好。

\documentclass[tikz]{standalone}

\definecolor{kesara}{HTML}{FF9933} % top stripe
\definecolor{madhya}{HTML}{FFFFFF} % middle stripe
\definecolor{harita}{HTML}{138808} % bottom stripe
\definecolor{ashokaneela}{HTML}{000080} % ashok chakra

\usetikzlibrary{calc,fit}
\tikzset{
  bharat/.style={ draw=ashokaneela,fill=ashokaneela }
}

\begin{document}
\begin{tikzpicture}[scale=.9]
  \fill [kesara] (0,400mm) rectangle (900mm,600mm);
  \node (mid) [fit={ (0,200mm) (900mm,400mm) }, rectangle, inner sep=0, fill=madhya] {};
  \fill [harita] (0,0) rectangle (900mm,200mm);
  \fill (mid) [ashokaneela] circle (93mm) ;
  \fill (mid) [white] circle (80mm) ;
  \fill (mid) [ashokaneela] circle (16mm) ;
  \foreach \x in {0,..., 23}{
  \fill [ashokaneela] ($ (mid) + (7.5+15*\x:80mm) $) circle (4mm) ; 
  \fill [ashokaneela, rotate around = {15*\x:(mid)}] 
        ($ (mid) + (10mm,0) $) -- +(26mm,-3mm) -- 
        ($ (mid) + (92mm,0) $) -- +(-56mm,3mm) -- cycle ; 
  }
\end{tikzpicture}
\end{document}
