生成带有数字表盘的模拟时钟，添加秒数和罗马数字

看看优秀的答案这里，我不禁想知道如何才能完成两个看似简单的修改：

  1. 我希望能够生成一个传统的罗马数字时钟；
  2. 在标签上添加秒数会很有帮助，这样就可以轻松地帮助孩子们学习如何用模拟时钟看时间。

MWE 来自 Harish Kumar 对上一个问题的回答：

\documentclass[dvipsnames]{article}
\usepackage{tikz}

\begin{document}
\newcommand\clock[4][2]{%
\begin{tikzpicture}[scale=#1,line cap=round,line width=#1*3pt]
\filldraw [fill=Goldenrod!20] (0,0) circle (2cm);
\foreach \angle / \label in
{0/3, 30/2, 60/1, 90/12, 120/11, 150/10, 180/9,
210/8, 240/7, 270/6, 300/5, 330/4}
{
\draw[line width=#1*1pt] (\angle:1.8cm) -- (\angle:2cm);
\draw (\angle:1.4cm) node[scale=#1]{\textsf{\label}};
}
\foreach \angle in {0,90,180,270}
\draw[line width=#1*2pt] (\angle:1.6cm) -- (\angle:2cm);
\node[draw=none,font=\tiny,text=red,scale=#1] at (0,.9cm) {TICK-TOCK};
\draw[rotate=90,line width=#1*2pt] (0,0) -- (-#2*30-#3*30/60:0.7cm); % hours
\draw[rotate=90,line width=#1*1.5pt] (0,0) -- (-#3*6:1cm); % minutes
\draw[rotate=90,line width=#1*.6pt,red] (0,0) -- (-#4*6:1.2cm); % seconds
\path [fill=black] (0,0) circle (3pt);
\path [fill=red] (0,0) circle (1.5pt);
%
\end{tikzpicture}%
}
%%\syntax
%% \clock[<optional scaling dim>]{<hour>}{<minute>}{<seconds>}
\noindent\clock{9}{35}{55}\clock[1.2]{1}{15}{30} \clock[.9]{2}{25}{15}
\clock[.7]{12}{58}{10} \clock[.5]{6}{10}{55}
\clock[.3]{12}{20}{22} \clock[.2]{8}{0}{5}


\end{document}

我猜它类似于：

\foreach \angle / \label in
{0/3, 30/2, 60/1, 90/12, 120/11, 150/10, 180/9,
210/8, 240/7, 270/6, 300/5, 330/4}
{
\draw[line width=#1*1pt] (\angle:1.8cm) -- (\angle:2cm);
\draw (\angle:1.4cm) node[scale=#1]{\textsf{\label}};
}

但我不知道从这里该去哪里。

答案1

我喜欢尽可能多地使用 PGF 的样式和关键系统，所以我做了这个小解决方案。

我添加了 PGFmath 函数croman和cRoman，它们接受一个整数并以罗马数字输出一个字符串（即，它不能用作另一个函数的数学输入）。c表示“三三”用来代替“IV”。

由于无法使用键重新声明 PGFmath 函数，因此declare function我使用.code带有辅助宏的键\clockF。这不是最好的解决方案，但它在这里有效。

最后一个例子为秒（分钟）和第三（秒）级别重新定义了这些函数。

答案2

有一个更简单的 sans-seconds 解决方案重现类似于 ifsym 包提供的模拟时钟

但是如果没有光彩，TikZ 答案又有什么用呢？

\documentclass[border=5mm,tikz]{standalone}

\shade[s,shading angle=15]  circle (22mm) circle (25mm);

正如你所看到的，我突然对钟表指针感到厌倦了:)

并没有声称在功能方面增加了太多内容，而只是增加了一个“图标”风格的时钟：

\shade [shaded=black!75:black!50:black!25 @ 45]  circle [radius=12.5];
\fill [black!90] circle [radius=12];
\foreach \i [evaluate={\j=90-\i*30; \k=mod(\i,3)==0;\m=int(\i*5);}] in {1,...,12}
  \draw [white, line width=\k ? .4ex : .2ex] (\j:11.5) -- (\j:11-\k) 
    (\j:10) node [anchor=\j, text=black!20, font=\sffamily]  {\expandafter\uppercase\expandafter{\romannumeral\i}};

添加这些：

\foreach \angle [count=\label] in {84,78,...,-270}
{
\draw[line width=1pt] (\angle:1.9cm) -- (\angle:2cm);
\draw (\angle:1.7cm) node[scale=0.25]{\textsf{\label}};
}
