\frownie 和 \smiley 之间的某个字符

\frownie 和 \smiley 之间的某个字符

在 beamer 演示中，我想比较和对比几种替代方案。对于每种方案，我想强调“优点”（带有\item[\Large\smiley]）、“缺点”（带有\item[\Large\frownie]）和“中立”意见。是否有一个符号的表情既不快乐也不悲伤，而是中立的？

答案1

这是一个tikz版本，您可以使用\Simley{<smile_level>}和控制微笑级别（如下图所示设置）1，从非常高兴到-1非常不高兴：

在此处输入图片描述

实际上，您可以使用更大的数字，但结果可能不理想。1.75下面代码中的模糊因子被使用，因此合理的范围是-1...1您可以根据需要调整它们。

代码：

\documentclass{article}
\usepackage{tikz}

\newcommand{\Simley}[1]{%
\begin{tikzpicture}[scale=0.11]
    \newcommand*{\SmileyRadius}{1.0}%
    \draw [fill=brown!10] (0,0) circle (\SmileyRadius)% outside circle
        %node [yshift=-0.22*\SmileyRadius cm] {\tiny #1}% uncomment this to see the smile factor
        ;  

    \pgfmathsetmacro{\eyeX}{0.5*\SmileyRadius*cos(30)}
    \pgfmathsetmacro{\eyeY}{0.5*\SmileyRadius*sin(30)}
    \draw [fill=cyan,draw=none] (\eyeX,\eyeY) circle (0.15cm);
    \draw [fill=cyan,draw=none] (-\eyeX,\eyeY) circle (0.15cm);

    \pgfmathsetmacro{\xScale}{2*\eyeX/180}
    \pgfmathsetmacro{\yScale}{1.0*\eyeY}
    \draw[color=red, domain=-\eyeX:\eyeX]   
        plot ({\x},{
            -0.1+#1*0.15 % shift the smiley as smile decreases
            -#1*1.75*\yScale*(sin((\x+\eyeX)/\xScale))-\eyeY});
\end{tikzpicture}%
}%

\begin{document}
  \Simley{1}
  \Simley{0.5}
  \Simley{0}
  \Simley{-0.5}
  \Simley{-1}
\end{document}

这是一张相当有趣的脸。请进一步调整以获得更具表现力的表情。

\documentclass{beamer}
\usepackage{tikz}

\newcommand{\smiley}{\tikz[baseline=-0.75ex,black]{
    \draw circle (2mm);
\node[fill,circle,inner sep=0.5pt] (left eye) at (135:0.8mm) {};
\node[fill,circle,inner sep=0.5pt] (right eye) at (45:0.8mm) {};
\draw (-145:0.9mm) arc (-120:-60:1.5mm);
    }
}

\newcommand{\frownie}{\tikz[baseline=-0.75ex,black]{
    \draw circle (2mm);
\node[fill,circle,inner sep=0.5pt] (left eye) at (135:0.8mm) {};
\node[fill,circle,inner sep=0.5pt] (right eye) at (45:0.8mm) {};
\draw (-145:0.9mm) arc (120:60:1.5mm);
    }
}

\newcommand{\neutranie}{\tikz[baseline=-0.75ex,black]{
    \draw circle (2mm);
\node[fill,circle,inner sep=0.5pt] (left eye) at (135:0.8mm) {};
\node[fill,circle,inner sep=0.5pt] (right eye) at (45:0.8mm) {};
\draw (-135:0.9mm) -- (-45:0.9mm);
    }
}

\begin{document}
\begin{frame}{Pros, Cons and others}
\begin{itemize}
    \item[\smiley] Yay!
    \item[\frownie] Bah!
    \item[\neutranie] Wadeva...
\end{itemize}
\end{frame}

这是 Knuth 自己提出的一个非 Tikz 解决方案，仅供参考。最初发表在他的论文中，名字很贴切稳定的丈夫。

在此处输入图片描述

\documentclass{article}
%% Knuths smile box from 
%\centerline{\bf Stable Husbands}
%\bigskip
%\centerline{\sl Donald E. Knuth, Rajeev Motwani, and Boris Pittel}
%\centerline{\sl  Computer Science Department, Stanford University}
\def\pfbox % new experimental version (DEK, November 88)
{{\ooalign{\hfil\lower.06ex % a smiley face
 \hbox{$\scriptscriptstyle\frown$}\hfil\crcr
 \hfil\lower.7ex\hbox{\"{}}\hfil\crcr
 \mathhexbox20D}}}
\begin{document}
\Huge \pfbox
\end{document}

当然，这是数学家的皱眉。\texttt{\meaning\frown}.将其改为\frown减号，即可得到非常中性的符号：

我不是表情符号专家，所以我画了一些基本的表情符号。最后我更改了现在我定义的 、 和 的名称emoticon happy。emoticon sad我emoticon straight face现在emoticon wink会将最终的库放在我的网站上。形状并不完美，因为当我在里面添加一些文本时会出现问题。

首先我创建了文件：tikzlibraryshapes.emoticon.code.tex

第一个表情符号的名称是emoticon :-)。第二个是emoticon :-(。下面是如何使用这两个新形状的示例：

\documentclass[11pt]{scrartcl}
\usepackage{tikz}
\usetikzlibrary{shapes.emoticon}
\begin{document}

\vspace{1cm}
\tikz \node [shape=emoticon happy,draw,fill=yellow]  {};    
\tikz \node [shape=emoticon sad,draw,fill=yellow]  {};

\begin{tikzpicture}[ultra thick]
  \node [shape=emoticon happy,draw,scale=8,fill=orange]  {};
\end{tikzpicture}
\begin{tikzpicture}[ultra thick]
  \node [shape=emoticon sad,draw,scale=8,fill=orange]  {};
