使用 svg 包和 inkscape 将 svg 转换为 tex：使文本在形状内换行

我使用 LuaLaTeX（最新的 MikTeX +TexStudio），并希望在我的文档中使用在 MS Visio 中创建的 SVG 插图。这是原始图像

作为快速和污垢修复我对 svg 包的问题我使用批处理文件手动启动 inkskape，方式与 svg 包相同

@echo off
"C:\Program Files\Inkscape\inkscape.exe" -z -D -f %1 -A "%~dpn1.pdf" --export-latex

并编译文档。以下是它在 PDF 中的样子。 结果图像

看起来相当不错：形状正确，字体根据文档的字体进行了调整，并在适当位置进行了放大。除了它没有在形状内换行之外。强制换行的尝试\newline被忽略。以下是 pdf_tex 文件的内容

有办法修复吗？可能是在图片中添加一些额外的 LaTeX 代码？

答案1

您可以手动将文本分成两行：

\documentclass{article}

\usepackage{graphicx}
\usepackage{xcolor}

\begin{document}

\setlength{\unitlength}{497.74924049bp}%
\begin{picture}(1,0.40658965)%
  \put(0.06182823,0.21124862){\color[rgb]{0,0,0}\makebox(0,0)[lb]{\smash{{\large Raspberry PI 2}}}}%
  \put(0.06182823,0.18){\color[rgb]{0,0,0}\makebox(0,0)[lb]{\smash{Reads the data and adjusts the current}}}%
\end{picture}%

\end{document}

或者，您可以将 包装在\parbox适当宽度中以实现自动换行：

\documentclass{article}

\usepackage{graphicx}
\usepackage{xcolor}

\begin{document}

\setlength{\unitlength}{497.74924049bp}%
\begin{picture}(1,0.40658965)%
  \put(0.06182823,0.21124862){%
    \parbox{3cm}{%  
        {\large Raspberry PI 2}
        Reads the data and adjusts the current
    }%
  }%
\end{picture}%

\end{document}
