Desenhando a bandeira indiana usando tikz

Question

Estou tentando desenhar uma bandeira indiana usando ideias deaquie outros, incluindo um símbolo Ashok-chakra deexemplo no verso. Quero ter a codificação adequada com as dimensões corretas mencionadas emWikipédia. Tenho uma dúvida sobre o tamanho do Ashok-Chakra. Qualquer um me ajude por favor! Meu MWE é fornecido abaixo:

\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}

Answer 1

Para impor as nove medidas diferentes, pode-se usar o .is choicemanipulador de chaves do pgfkeysmaterial. Eu reimplementei o código do sinalizador (que provavelmente precisa de mais ajustes para obter os detalhes do Ashoka Chakra exatamente corretos). Observe que para tamanhos maiores de bandeira, os vetores xe yprecisam ser alterados para evitar dimension too largeerros:

\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},

      \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}

  \pic at (flag.south) (flag)
    {Flag of India={size=\size, shift=(270:\flagheight*3/4)}};

Answer 2

Você tem mais problemas:

• colocar picpor conta própria tikzpictureé uma abordagem errada
• Devido à scaleboxnecessidade de picusar coordenadas multiplicadas pelo inverso do fator de escala.

\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}

Melhor resultado você obtém, se não usar scaleboxe dimensionar manualmente todas as coordenadas nas picfiguras:

\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}

No MWE acima, os estilos para ashokchakrasão movidostikzpicture

Answer 3

inspirado em uma das soluções aqui, sem nested tikzpicturee com uma ligeira mudança de roda. Escala muito bem também.

\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}
