使用 xelatex 在独立系统中定义字体大小

Question

我想在独立环境中生成与主文档匹配的 tikz 图片的 svg 图像。到目前为止，一切正常。但是，我在定义主文档的字体大小时遇到​​了困难，在本例中，主文档是字体大小为 9pt 的 beamer 演示文稿。如何在独立环境中将 normalfontsize 也设置为 9pt？

主要文件的 MWE：

\documentclass[9pt]{beamer}
\usepackage{fontspec}
\setmainfont{Arial}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}

\draw (-0.4,0) -- (10.6,0); 

\node[anchor=north east,align=right, inner sep=2mm, yshift=-0.5cm, xshift=0cm,font=\centering\bfseries\huge](a) at (current bounding box.east){This is the Main Title:};

\node[anchor=north east,align=right, inner sep=2mm, yshift=0.2cm, xshift=0cm,font=\centering\bfseries\large](b) at (a.south east){And this is the Subtitle that fits within the black border lines.};

\node[anchor=north east,align=right, inner sep=2mm, yshift=-0.4cm, xshift=0cm,font=\centering](c) at (b.south east){Name 1, Name 2};

\draw (-0.4,0) -- (-0.4,-5);
\draw (10.6,0) -- (10.6,4.5); 
\end{tikzpicture}

\end{document}

\node[anchor=north east,align=right, inner sep=2mm, yshift=-0.5cm, xshift=0cm,font=\centering\bfseries\huge](a) at (current bounding box.east){This is the Main Title:};

\node[anchor=north east,align=right, inner sep=2mm, yshift=0.2cm, xshift=0cm,font=\centering\bfseries\large](b) at (a.south east){And this is the Subtitle that fits within the black border lines.};

\node[anchor=north east,align=right, inner sep=2mm, yshift=-0.4cm, xshift=0cm,font=\centering](c) at (b.south east){Name 1, Name 2};

\draw (-0.4,0) -- (-0.4,-5);
\draw (10.6,0) -- (10.6,4.5); 
\end{tikzpicture}

\end{document}

不清楚您想要得到什么。我怀疑是以下示例中的一个：

生成者：

\documentclass[margin=1mm,% added that border is better visible
                          % in real document you can delete margin
               tikz,convert=pdf2svg]{standalone}
%\documentclass[tikz, margin=1mm]{standalone}
\usetikzlibrary{fit,
                positioning}
\usepackage[inkscapelatex=false]{svg}
\usepackage{fontspec}
\setmainfont{Arial}

\begin{document}
    \begin{tikzpicture}[
node distance = 2mm and 0mm,
   box/.style = {inner sep=1mm, font=\bfseries#1, 
                 anchor=north east}
                        ]
\node[box=\huge](a) 
    {This is the Main Title:};
\node[box=\large, below left=of a.south east](b) 
    {And this is the Subtitle that fits within the black border lines.};
\node[box=\normalsize, below left=7mm and 0mm of b.south east](c) 
    {Name 1, Name 2};
%
\node[draw, inner sep=2mm, fit=(a) (b) (c)] {};
    \end{tikzpicture}
\end{document}

或者

由。。。生产：

\documentclass[margin=1mm,% added that border is better visible
                          % in real document you can delete margin
               tikz,convert=pdf2svg]{standalone}
%\documentclass[tikz, margin=1mm]{standalone}
\usetikzlibrary{fit,
                positioning}
\usepackage[inkscapelatex=false]{svg}
\usepackage{fontspec}
\setmainfont{Arial}

\begin{document}
    \begin{tikzpicture}[
node distance = 2mm and 0mm,
   box/.style = {inner sep=1mm, font=\bfseries#1}
                        ]
\node[box=\huge](a)  
    {This is the Main Title:};
\node[box=\large, below=of a](b) 
    {And this is the Subtitle that fits within the black border lines.};
\node[box=\normalsize, 
      below=7mm of b](c) 
    {Name 1, Name 2};
%
\node[draw, inner sep=2mm, fit=(a) (b) (c)] {};
    \end{tikzpicture}
\end{document}

关于您的 MWE 的一些评论：

• 已\documentclass[crop,tikz,convert=pdf2svg]{standalone}加载tikz包，因此不需要再次加载\usepackage{tikz}
• 在没有定义节点的节点中，text width节点的内容总是在节点的中间，所以定义align=...是没有意义的
• 不font存在选项\centering
• 所有节点样式定义仅在使用的字体大小上有所不同，因此使用确定字体大小的自由参数定义通用节点形状样式是合理的（这样代码会变得更短更清晰）
• 似乎（最终）current bounding box正处于其使用未知的时候

附录： 如果您希望在多行中显示这些标题，则可以使用此标题。这可以通过text width在节点形状样式选项中规定来实现：

\documentclass[margin=1mm,% added that border is better visible
               tikz,convert=pdf2svg]{standalone}
\usetikzlibrary{fit,
                positioning}
\usepackage[inkscapelatex=false]{svg}
\usepackage{fontspec}
\setmainfont{Arial}

\begin{document}
    \begin{tikzpicture}[
node distance = 2mm and 0mm,
   box/.style = {text width=11cm, align=right, 
                 inner sep=1mm, font=\bfseries#1}
                        ]
\node[box=\huge](a)
    {This is the Main Title:};
\node[box=\large, below=of a](b)
    {And this is the Subtitle that fits within the black border lines.};
\node[box=\normalsize,
      below=7mm of b](c) 
    {Name 1, Name 2};
%
\node[draw, inner sep=2mm, fit=(a) (b) (c)] {};
    \end{tikzpicture}
\end{document}

或者使用居中文本：

\documentclass[margin=1mm,% added that border is better visible
                          % in real document you can delete margin
               tikz,convert=pdf2svg]{standalone}
\usetikzlibrary{fit,
                positioning}
\usepackage[inkscapelatex=false]{svg}
\usepackage{fontspec}
\setmainfont{Arial}

\begin{document}
    \begin{tikzpicture}[
node distance = 2mm and 0mm,
   box/.style = {text width=11cm, align=center, 
                 inner sep=1mm, font=\bfseries#1}
                        ]
\node[box=\huge](a)
    {This is the Main Title:};
\node[box=\large, below=of a](b) 
    {And this is the Subtitle that fits within the black border lines.};
\node[box=\normalsize,
      below=7mm of b](c) 
    {Name 1, Name 2};
%
\node[draw, inner sep=2mm, fit=(a) (b) (c)] {};
    \end{tikzpicture}
\end{document}
