在 Asymptote 中更改字体

我想用几种不同的字体呈现相同的文本，但是当我执行以下操作时：

import settings;
import fontsize;
settings.tex="lualatex";
outformat="pdf";

size(9cm);
defaultpen(fontsize(10pt));
defaultpen(0.1);

texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
draw(scale(0.1) * texpath("text"));
texreset();
texpreamble("\usepackage{fontspec}\setmainfont{Arial}");
draw(shift(3, 0) * scale(0.1) * texpath("text"));

生成的图片仅包含用 Courier New 编写的文本。如果我将第 11 行和第 13 行更改为：

draw(scale(0.1) * texpath("text1"));
draw(shift(3, 0) * scale(0.1) * texpath("text2"));

文本渲染正确。这是怎么回事？我该如何用不同的字体渲染相同的文本？我在 Windows 7 上使用 TeX Live 2017。相关说明：当我尝试渲染带有标签的文本时，LuaLaTeX 会产生错误，如下所示：

texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
label("text", (0,0));
texreset();
texpreamble("\usepackage{fontspec}\setmainfont{Arial}");
label("text", (3,0));

错误：

答案1

...这是我对 xelatex 的 MWE，遵循说明这里。

\documentclass{standalone}
\usepackage{asymptote}
\begin{document}
\begin{asy}
import settings;
import fontsize;
//settings.tex="lualatex";
outformat="pdf";

size(9cm);
defaultpen(fontsize(10pt));
defaultpen(0.1);

texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
texpreamble("\newfontfamily\myfont{Arial}");
draw(scale(0.1) * texpath("text"));
draw(shift(3, 0) * scale(0.1) * texpath("{\myfont text}"));
\end{asy}
\end{document}

在此处输入图片描述

如果你编译

import settings;
import fontsize;
settings.tex="lualatex";
outformat="pdf";

size(9cm);
defaultpen(fontsize(10pt));
defaultpen(0.1);

texpreamble("\usepackage{fontspec}\setmainfont{Courier New}");
texpreamble("\newfontfamily\myfont{Arial}");
draw(scale(0.1) * texpath("text"));
draw(shift(3, 0) * scale(0.1) * texpath("{\myfont text}"));

使用asy -V，正如您所做的那样。
