较粗的波浪下划线

Question

\uwave我发现ulem包裹，其定义在ulem.sty：

% Now define various special underlines.  All the definitions go like
% \def \command {\bgroup \markoverwith{something} \ULon}

% For drawing a wavey underline instead of a straight one the command
% is \uwave (under-wave) which uses the wiggle from 6-pt lasy font:

\def\uwave{\bgroup \markoverwith{\lower3.5\p@\hbox{\sixly \char58}}\ULon}
\font\sixly=lasy6 % does not re-load if already loaded, so no memory problem.

我想保持下划线波浪，但是更厚，有人知道怎么做吗？

Answer 1

有粗体字体变体lasy：lasyb10。需要进行一些缩放以适合字体字符的宽度lasy6（例如，由于设计尺寸不同）。

该示例是纯 TeX 语法，因此我保留它。

% plain TeX    
\input ulem.sty\relax
\catcode`\@=11 %

\font\uwavefontold=lasy6
\font\uwavefont=lasyb10 scaled 652

\def\uwaveold{%
  \bgroup
    \markoverwith{%
      \lower3.5\p@\hbox{\uwavefontold\char58}%
    }%
  \ULon
}
\def\uwave{%
  \bgroup
    \markoverwith{%
      \lower3.5\p@\hbox{\uwavefont\char58}%
    }%
  \ULon
}

\uwaveold{Hello World}

\uwave{Hello World}

\bye
