tikz 画一个视力表

文本排版 2019-09-15 01:20  浏览 :472


主要用到一个随机函数setrand{<minimum>}{<maximum>}{<multiple of>}{<seed>}

有重复代码使用,但是还没找到好的解决方案,希望大神可以提下意见!

使用 xelatex 编译

效果图如下

代码如下

\\documentclass[tikz]{standalone}
\\usepackage{ctex}
\\usepackage{tikz}
\\usetikzlibrary{calc} 
\\usetikzlibrary{shapes.geometric}
\\usepackage{pgfmath}
\\newcommand\\randmin{}
\\newcommand\\randmax{}
\\newcommand\\randmultof{}
\\newcommand\\setrand[4]%
  {\\def\\randmin{#1}%
   \\def\\randmax{#2}%
   \\def\\randmultof{#3}%
   \\pgfmathsetseed{#4}%
  }
\\newcommand\\nextrand
  {\\pgfmathparse{int(int((rnd*(\\randmax-\\randmin+1)+\\randmin)/\\randmultof)*\\randmultof)}%
   \\xdef\\thisrand{\\pgfmathresult}%
  }
\\setmainfont{Arial}
\\begin{document}
\\setrand{0}{720}{90}{180}

\documentclass[tikz]{standalone} \usepackage{ctex} \usepackage{tikz} \usetikzlibrary{backgrounds} \setmainfont{Arial} \begin{document} \begin{tikzpicture} \draw[line width=2.5pt] (0,-3)--(0,3); \draw[line width=2.5pt] (3,0)--(-3,0); \pgfmathsetseed{666} \def\circlerd{100}%用于计算圆的半径,单位将是 pt \foreach \y[count=\yj from 0] / \s in {1/5.4,2/5.3,3/5.2,4/5.1,5/5.0,6/4.9,7/4.8,8/4.7,9/4.6,10/4.5} { \pgfmathparse{\circlerd +0.5*\y*10+0.5*\yj*10+60+ln(\y)*60} \xdef\circlerd{\pgfmathresult}%第 \y 个圆的半径,单位将是 pt \pgfmathparse{\y*10} \edef\textboxdm{\pgfmathresult pt}% 文字盒子的尺寸 \foreach \x in {0,7.5,...,352.5} { \pgfmathsetmacro{\thisrand}{random(1,4)*90} \pgfmathsetmacro{\isnumposition}{equal(mod(\x,90),0) ? 1 : 0} \ifnum\isnumposition=0% \node at (\x:\circlerd pt) {{\resizebox{\textboxdm}{!}{{\rotatebox{\thisrand}{E}}}}}; \else \node at (\x:\circlerd pt) {{\resizebox{\textboxdm}{!}{\s}}}; \fi } } \begin{scope}[on background layer] \fill[fill=gray!40](0,0)circle(\circlerd pt + 120pt); \fill[fill=white](0,0)circle(\circlerd pt + 100pt); \end{scope} \end{tikzpicture} \end{document} 就想到这么多了
