如何在文档封面上添加背景零，就像在电影《黑客帝国》的屏幕上一样？

我想先制作一张黑色（或其他颜色）的封面照片，然后使用零、费曼图等随机分布在页面上，字体为绿色。字体必须是浅色的，这样我才能将其用作封面的背景。在 Latex 中可以这样做吗？

答案1

我对你的问题有点困惑，因此我不确定这是否能解决你的问题。如果你想让零随机分布在你的页面中，但又放置在一种模拟矩阵代码的“网格”中，你可能会发现这种方法很有用：

\documentclass[11pt]{article}
\usepackage{tikz}
\usetikzlibrary{backgrounds,calc}
\definecolor{mybackground}{rgb}{0,0,0}
\definecolor{mygreen}{RGB}{21,138,12}
\def\myopacity{0.7} %From 0 to 1 
\def\ncol{40}
\def\nrow{40}
\begin{document}
\begin{tikzpicture}[remember picture,overlay,show background rectangle, 
background rectangle/.style={fill=mybackground},color=mygreen,align=center]
\pgfmathsetseed{1} %for reproducibility
\pgfmathsetmacro{\ncolEND}{\ncol-1}
\pgfmathsetmacro{\nrowEND}{\nrow-1}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\pgfmathdeclarerandomlist{letters}{%
{0}{}
}% End of List
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\foreach \i in {1,...,\ncolEND}{
 \foreach \j in {1,...,\nrowEND}{
 \pgfmathrandomitem{\letter}{letters}
 \node at ($(current page.south west)+(\paperwidth/\ncol*\i,\paperheight/\nrow*\j)$) {\letter};
 }}
\fill [draw=none, fill=white, fill opacity=\myopacity] (current page.south west)--(current page.north west)--(current page.north east)--(current page.south east)--cycle;
\end{tikzpicture}
\thispagestyle{empty}
\begin{center}
\Huge\texttt{\textcolor{mygreen}{The Matrix has you}}
\end{center}

\newpage
Another page
\end{document}

输出结果如下：零序列

我用的是Ti钾Z 使用键remember picture和overlay库中的一些选项来生成背景backgrounds。该库calc用于计算每个字符相对于原点（在本例中为页面的左下角）的位置以及要打印的列数\ncol和行数。该函数\nrow\pgfmathsetseed{1}数。该函数定义了在 Ti 中实现的随机序列的线性同余生成器的种子。钾Z。长话短说，如果您复制并粘贴上述代码，您将获得与附件完全相同的输出。下一步是存储一个包含零和“void”的列表，因此需要函数\pgfmathdeclarerandomlist{{0}{}}。第一个\foreach表示“针对每一列”，而第二个表示迭代列中的每个元素并打印由随机选择的符号\pgfmathrandomitem{\letter}{letters}。最后，该命令\fill将不透明度添加到图像，以便可以将其用作背景。

如果您想添加其他符号，例如日文字符和反射数字，您可以简单地将它们添加到列表中，如下所示：

\pgfmathdeclarerandomlist{letters}{%
{\begin{CJK}{UTF8}{min} リ \end{CJK}}
{\begin{CJK}{UTF8}{min} ス \end{CJK}}
{\begin{CJK}{UTF8}{min} ト \end{CJK}}

您需要使用此软件包CJKutf8来打印日文符号

最后，如果你想打印更接近矩阵代码的东西，事情会变得更加复杂。我使用该包ifthen对在特定范围内生成的随机整数（称为）进行测试\FLAG。根据值\FLAG，符号序列将在图像的顶部或底部对齐。这是结果： 矩阵代码

说到费曼图，要想以好的方式将它们包含在内，你需要一个有艺术天赋的人，而我没有。不过，我可以提出一种将它们包含在页面中的方法。为了得到典型的正弦段，我使用了这里提供的解决方案：TikZ：没有直线段的装饰路径它创建了一个名为的新装饰complete sines。然后我定义了一个名为的新命令，\FeynmanDiagramCover灵感来自这篇文章TikZ 中的技术图纸尺寸标注这样：

\makeatletter
\newcommand{\FeynmanDiagramCover}[1]{%
{\tikzset{>=stealth}
\coordinate (@0) at #1;
\coordinate (@1) at ($(@0)+(180:{2+2*rnd})$);
\coordinate (@2) at ($(@1)+(120+30*rnd:3+2*rnd)$);
\coordinate (@3) at ($(@1)+(210+30*rnd:3+2*rnd)$);
\coordinate (@4) at ($(@0)+(0:2+2*rnd)$);
\coordinate (@5) at ($(@4)+(30+30*rnd:3+2*rnd)$);
\coordinate (@6) at ($(@4)+(-30-30*rnd:3+2*rnd)$);
\draw [->-] (@1)--(@2);
\draw [->-] (@3)--(@1);
\draw decorate [decoration={complete sines,segment length=0.5cm,amplitude=0.5cm,mirror,start up,end up}] {(@1)--(@4)};
\draw [->-] (@4)--(@5);
\draw [->-] (@6)--(@4);
}}
\makeatother

线条样式->-复制自Tikz：箭头位于中心。在坐标定义中我添加了rnd几次。它会影响正弦段（虚线）的长度、直线之间的角度和长度（虚线区域），如下图所示： 使用命令 \FeynmanDiagramCover 绘制费曼图

要将图表包含在封面中，只需发出命令\FeynmanDiagramCover{(coordinate)}，其中应与Ti 中可用的节点(coordinate)之一相关current page钾Z 加上距离（\paperwidth例如\paperheight类似于\FeynmanDiagramCover{($(current page.south west)+(.3*\paperwidth,.2*\paperheight)$)}works）。使用 OP 提出的关于 Matrix 代码外观的设置，最终结果将是： 包含矩阵代码和费曼图的最终封面页

该命令\FeynmanDiagramCover发出 4 次，并在scope修改图表比例（0.4）和旋转的环境中。这是最终输出的代码：
