![使用 Tikz 的新 R 徽标](https://linux22.com/image/315525/%E4%BD%BF%E7%94%A8%20Tikz%20%E7%9A%84%E6%96%B0%20R%20%E5%BE%BD%E6%A0%87.png)
我想R
用 制作以下新标志 tikz
。
我的 MWE 输出为:
\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[]
\node[blue] at (0,0) {R};
\draw (0,0) ellipse (28pt and 20pt);
\draw (0,0) ellipse (18pt and 14pt);
\end{tikzpicture}
\end{document}
我的输出与期望结果不太接近。任何这方面的帮助都将不胜感激。谢谢

最好的办法是从 Inkscape 导出所有内容,但在这里我仅导出了 R 字母,并通过旧徽标颜色将其放置在省略号上。您可能需要适当调整它,我只是在这里进行近似。

答案3
我无法在新版本的 inkscape 上重新安装 svg2tikz 插件,但在 ubuntu 的命令行中,可以运行:
wget https://upload.wikimedia.org/wikipedia/commons/1/1b/R_logo.svg
pip install git+git://github.com/aloisklink/svg2tikz --user
svg2tikz --figonly R_logo.svg
第一行下载 R 徽标的 svg,第二行安装 svg2tikz python 库,第三行将 svg 文件导出到 tikz。注意,我安装的是原始 svg2tikz 的一个分支
你得到:
