如何自动调整给定的行

你们中有些人可能知道 Phillip Tanedo 的 FlipBeamertheme（http://www.physics.uci.edu/~tanedo/files/code/FlipBeamerTemplate.pdf）

我喜欢它的标题风格。Tanedo 用了一张图片：

这三行文字的两边都经过了调整。我猜 Tanedo 一定花了不少时间调整字体大小、字距和字间距，才做到了这一点。

现在我想知道是否可以使用 xelatex 或 lualatex “自动”实现该效果。

类似于计算所需字体大小然后微调字距的环境。

具有可调节功能的解决方案：

\documentclass{article}
\usepackage{fontspec}
\usepackage{graphicx}
\usepackage{xparse}

\setsansfont{Gill Sans}

\ExplSyntaxOn
\NewDocumentCommand{\tanedo}{O{}m}
 {% do everything in a group not to clobber previous values
  \group_begin:
  % evaluate the keys in the optional argument
  \keys_set:nn { schmendrich/tanedo } { #1 }
  % pass control of typesetting to an internal function
  \schmendrich_tanedo:n { #2 }
  % close the group
  \group_end:
 }

% define the needed keys
\keys_define:nn { schmendrich/tanedo }
 {
  width .dim_set:N = \l_schmendrich_title_width_dim,
  skip  .dim_set:N = \l_schmendrich_title_skip_dim,
  skip  .initial:n = { 3pt },
  font  .tl_set:N  = \l_schmendrich_title_font_tl
 }

% a couple of needed variables
\seq_new:N \l_schmendrich_input_title_seq
\box_new:N \l_schmendrich_line_box

% the main function
\cs_new_protected:Npn \schmendrich_tanedo:n #1
 {
  % split the title argument into pieces at \\
  \seq_set_split:Nnn \l_schmendrich_input_title_seq { \\ } { #1 }
  % if no required width has been specified, determine the natural width
  % (the signal for this is the width variable is still 0pt
  \dim_compare:nT { \l_schmendrich_title_width_dim = 0pt }
   {
    \seq_map_inline:Nn \l_schmendrich_input_title_seq
     {% put the item in a box applying the chosen font
      \hbox_set:Nn \l_schmendrich_line_box { \tl_use:N \l_schmendrich_title_font_tl ##1 }
      % compare the width of the box with the last stored width value
      \dim_compare:nT { \l_schmendrich_title_width_dim < \box_wd:N \l_schmendrich_line_box }
       {% if the stored value is less than the current one, set accordingly
        \dim_set:Nn \l_schmendrich_title_width_dim { \box_wd:N \l_schmendrich_line_box }
       }
     }
   }
  % we do it in a minipage as wide as necessary
  \begin{minipage}{\l_schmendrich_title_width_dim}
  % some low level trickery
  \lineskiplimit=\c_max_dim % two lines will always be too near
  \lineskip = \l_schmendrich_title_skip_dim % so \lineskip will be used
  % apply \centering (not strictly necessary, though)
  \centering
  % set the font
  \tl_use:N \l_schmendrich_title_font_tl
  % typeset each line in a suitable \resizebox
  \seq_map_inline:Nn \l_schmendrich_input_title_seq
   {
    \resizebox{\l_schmendrich_title_width_dim}{!}{##1} \\
   }
  % finish off
  \end{minipage}
 }
\ExplSyntaxOff

\begin{document}

\sffamily

\tanedo{THIS IS A \\ SAMPLE \\ TALK TITLE}

\bigskip

\tanedo[font=\bfseries]{THIS IS A \\ SAMPLE \\ TALK TITLE}

\bigskip

\tanedo[width=5cm]{THIS IS A \\ SAMPLE \\ TALK TITLE}

\bigskip

\tanedo[width=5cm,skip=6pt,font=\bfseries]{THIS IS A \\ SAMPLE \\ TALK TITLE}

\end{document}

如果未指定宽度，则将按其自然大小测量线条，并使用最宽的线条来调整其他线条的大小。您还可以调整线条之间的间距（默认为 3pt）并设置字体属性。

每一行都设置为\resizebox具有适当宽度，通过\seq_map_inline:Nn处理先前存储的每一行\seq_set_split:Nnn。

width当未指定选项时，使用相同的想法来计算自然宽度。

和adjustbox。

\documentclass{article}
\usepackage{adjustbox}


\begin{document}
\noindent
\adjustbox{width=15mm,height=1.5ex}{THIS IS A}\\
\adjustbox{width=15mm,height=1.5ex}{SAMPLE}\\
\adjustbox{width=15mm,height=1.5ex}{TALK LITTLE}

\end{document}

这也可以做到\resizebox。

\documentclass{article}
\usepackage{graphicx}


\begin{document}
\noindent
\resizebox{15mm}{1.5ex}{THIS IS A}\\
\resizebox{15mm}{1.5ex}{SAMPLE}\\
\resizebox{15mm}{1.5ex}{TALK LITTLE}

\end{document}
