我试图代表我国的国旗。我输入了这段代码。但我认为星星、圆圈等的位置并不那么受尊重。此外,我有一个左边距“白色带”,我想消除它,但没有结果。
请您帮我获取正确的代码。

答案1
不需要 n-grams 代码。标准star
节点形状即可。
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric}
\begin{document}
\definecolor{red}{RGB}{206,17,38}
\noindent\begin{tikzpicture}
% Use wikipedia's dimensions
\fill[red] rectangle (12, 8);
\fill[white] (6,4) circle (2);
\fill[red] (6,4) circle (1.5);
\fill[white] (6.4,4) circle (1.2);
\node[star,fill=red, minimum size=1.8cm, rotate=90, star point ratio=2.617,inner sep=0pt] at (6.4,4) {};
% Star point ratio is GoldenRatio^2 (1.618^2)
\end{tikzpicture}
\end{document}
尺寸取自1999年法律之后的规范。该规范没有提及星形和旋转,但可以安全地假设它是一个正五角星,并且旗帜具有水平对称轴,这完成了所需的信息。
更新
有1999年之前版本:
在这种情况下,我编写了一个更复杂的代码,以展示不同的技术。标志中的所有元素都是 tikz 节点,样式定义它们的大小和位置。此外,所有尺寸都是相对的,\flagwidth
可以随意更改。
\documentclass{article}
\usepackage{tikz}
\begin{document}
\usetikzlibrary{shapes.geometric}
\definecolor{red}{RGB}{206,17,38}
\def\flagwidth{6cm}
\tikzset{
flag/.style = {
fill=red,
minimum width=\flagwidth,
minimum height=2/3*\flagwidth,
inner sep = 0pt,
},
inner circle/.style = {
fill = white,
minimum size=1/3*\flagwidth,
circle,
inner sep = 0pt,
},
crescent/.style = {
fill = red,
minimum size = 2/9*\flagwidth,
circle,
inner sep = 0pt,
after node path = {node[moon] {}},
},
moon/.style = {
fill = white,
xshift= 1/45*\flagwidth,
minimum size = 1/5*\flagwidth,
inner sep = 0pt,
circle,
},
inner star/.style = {
fill = red,
star,
inner sep = 0pt,
xshift= 1/30*\flagwidth,
minimum size=4/27*\flagwidth,
rotate=90,
star point ratio=2.617,
}
}
\noindent\begin{tikzpicture}%[scale=0.01]
% Use pre 1999 dimensions
% http://en.wikipedia.org/wiki/File:Mesures_drapeau_Tunisie_avant_1999.svg
\draw node[flag] {}
node[inner circle] {}
node[crescent] {}
node[inner star] {};

答案2
这是土耳其国旗:
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric}
\begin{document}
\definecolor{red}{RGB}{227, 10, 23}
\noindent\begin{tikzpicture}
% Use wikipedia's dimensions
\fill[red] rectangle (12, 8);%G=8, L=12, L=1.5 G
\fill[white] (4,4) circle (2);
\fill[red] (4.5,4) circle (1.6);
\node[star,fill=white, minimum size=2cm, rotate=90, star point ratio=2.617,inner sep=0pt] at (6.83333333333,4) {};
\end{tikzpicture}
\end{document}
答案3
根据其制作图纸绘制的突尼斯国旗和土耳其国旗l3draw
