如何将旭日图内的文字加粗并稍微增加字体大小？

我曾使用过如何在 Latex 中制作旭日图？并根据我创建旭日图的需求对其进行了定制。我需要将其中的所有文本加粗，如果可能的话，增加其中文本的大小。这是我的 MWE。

要更改字体样式，您需要修改文本内部的财产\环定义。具体来说，你必须改变这个：

decoration={
    text along path,
    raise=-3pt,
    text align={align=center},
    reverse path=\rpTF,
    text=#6 % <-------------- HERE!
}

更改为：

text={|\customannfont|#6}

和这个：

\node[inner sep=0pt, %%% If there is text, print it
text width=#3*\layerwd*3+\layerwd,
align=center,
rotate=\rpTF,
font=\normalsize] at (\tmp:#3*\layerwd+0.5*\layerwd) % <-------------- HERE!
{#6};

更改为：

font=\customannfont] at (\tmp:#3*\layerwd+0.5*\layerwd)

注意：您可以不使用 \customannfont，而只是简单地编写字体样式，如下所示：

%%% code before
text={|\bfseries\fontsize{10}{0}\selectfont|#6}
%%% other code
font=\fontsize{10}{0}\selectfont

使字体变成 10pt 并加粗。不过，我建议在\环定义，因此您只需修改一次就可以在代码的两个地方更改它，如下所示：

\newcommand{\customannfont}{\fontsize{10}{0}\selectfont}

\bfseries可以用和指定字体\large。

代码可以使用轮图包，是我写的。

弧线中的文本被赋予键arc data。此处，可用于将文本拆分为多行。此文本的方向取决于键 中给出的\\弧线中间的角度。此文本以 为中心位于弧线中。\WCmidanglearc data dirarc data pos=0.5
