并编译为pdflatex -shell-escape sample.tex
它产生了这个（我喜欢）：
但我被 困扰了[height=8px]。这是硬编码的，所以如果我改变字体大小，SVG 不会随之改变。如果我删除 的这一部分\includesvn{#1.svg}，那么我最终会得到
我如何获取当前字体高度，以便可以相应地缩放 SVG？
答案1
\baselineskip将随字体大小缩放。使用此系数。
\documentclass{article}
\usepackage{svg}
\newcommand\mtg[1]{%
\includesvg[height=0.6\baselineskip]{#1.svg}%
}
\begin{document}
\tiny This magic card costs \mtg{R} mana\\
\scriptsize This magic card costs \mtg{R} mana\\
\footnotesize This magic card costs \mtg{R} mana\\
\small This magic card costs \mtg{R} mana\\
\normalsize This magic card costs \mtg{R} mana\\
\large This magic card costs \mtg{R} mana\\
\Large This magic card costs \mtg{R} mana\\
\LARGE This magic card costs \mtg{R} mana\\
\huge This magic card costs \mtg{R} mana\\
\Huge This magic card costs \mtg{R} mana\\

优化（mrpiggi）：
如果您经常使用此命令，那么从性能角度考虑，只包含图形本身一次并将其存储在一个框中以便重复使用是合理的：
\newcommand\mtg[1]{%
\ifcsname mtg-#1-box\endcsname\else%
\expandafter\newbox\csname mtg-#1-box\endcsname%
\expandafter\sbox\csname mtg-#1-box\endcsname{%
\includesvg[latex=false]{#1.svg}%
}%
\fi%
\raisebox{-.05\baselineskip}{\resizebox{!}{.6\baselineskip}{%
\expandafter\usebox\csname mtg-#1-box\endcsname%
}}%
}
