![当两个 TikZ 图片在图形环境中并排放置时,SVG 效果不佳 - make4ht](https://linux22.com/image/440834/%E5%BD%93%E4%B8%A4%E4%B8%AA%20TikZ%20%E5%9B%BE%E7%89%87%E5%9C%A8%E5%9B%BE%E5%BD%A2%E7%8E%AF%E5%A2%83%E4%B8%AD%E5%B9%B6%E6%8E%92%E6%94%BE%E7%BD%AE%E6%97%B6%EF%BC%8CSVG%20%E6%95%88%E6%9E%9C%E4%B8%8D%E4%BD%B3%20-%20make4ht.png)
当我使用make4ht index.tex "xhtml"
编译文件时
\documentclass{report}
\ifdefined\HCode
\def\pgfsysdriver{pgfsys-dvisvgm4ht.def}
\fi
\usepackage{tikz}
\begin{document}
\begin{figure}
\begin{center}
\begin{tikzpicture}
\draw (0,0) rectangle (3,3);
\end{tikzpicture}
\begin{tikzpicture}
\draw (0,0) rectangle (3,3);
\end{tikzpicture}
\end{center}
\caption{Test.\label{fig:test}}
\end{figure}
\end{document}
第二个矩形对应的 SVG 文件无法正确编译,因此无法渲染。如果我将两个矩形一个放在另一个下面而不是并排放置(通过在两个 TikZ 图片之间添加一个空白行)
\documentclass{report}
\ifdefined\HCode
\def\pgfsysdriver{pgfsys-dvisvgm4ht.def}
\fi
\usepackage{tikz}
\begin{document}
\begin{figure}
\begin{center}
\begin{tikzpicture}
\draw (0,0) rectangle (3,3);
\end{tikzpicture}
\begin{tikzpicture}
\draw (0,0) rectangle (3,3);
\end{tikzpicture}
\end{center}
\caption{Test.\label{fig:test}}
\end{figure}
\end{document}
pdflatex
然后一切都按预期工作。无论哪种情况,PDF 都可以正确编译。这是一个错误吗tex4ht
?司机dvisvgm
,还是我用的不正确?
答案1
这是驱动程序中的一个错误dvisvgm4ht
。它根据垂直模式使用不同的 TeX4ht 命令将 TeX 代码转换为图像。它应该在所有情况下运行相同的命令。以下是更新的版本:
