Asymptote 和 lualatex 中的字体问题

我正在尝试在渐近线中绘制一个 3-d 图形。我使用 Arial 字体作为文本以及数学字母。我正在使用命令编译文件lualatex mwi-lines.tex，asy mwi-lines*.asy然后使用命令lualatex mwi-lines.tex。以下是显示问题的 MWI。

在输出中，图中的标签不是 Arial 格式的。但是，下面的文本以 Arial 格式显示，没有任何问题。

在此处输入图片描述 如何解决这个问题？

答案1

周围 LaTeX 代码中的字体设置不会自动传输到 Asymptote 代码。如果您检查（这是生成图形时mwi-lines-1.asy唯一能看到的东西），那么您将看不到任何字体命令。asy

settings.tex="lualatex";您可以使用和语句将它们添加到 Asymptote 代码中texpreamble("")。代码片段：

\begin{asy}
        settings.tex="lualatex";
        settings.outformat = "pdf";
        settings.prc = false;
        texpreamble("\usepackage{unicode-math}\setmathfont{TeX Gyre DejaVu Math}\setmathfont{Nimbus Sans}[Scale=1.1,range=up/{num,Latin,latin}]
\setmathfont{Nimbus Sans}[Scale=1.1,range=it/{num,Latin,latin}]
\setmathfont{Nimbus Sans Bold}[Scale=1.1,range=bfup/{num,Latin,latin}]");

我使用了 Nimbus Sans，因为我没有安装 Arial，但它应该是类似的。

请注意，unicode-math您可以使用\symbf而不是来加粗数学。还请注意，您应该使用 范围\mathbf指定 的加粗变体。\setmathfontbfup
