文档第 2 部分的封面

Question

这个问题是从帖子中找到的这里。我想获取生成此封面的代码这里：

我仍然无法让整页图像tikz显示出来。以下是根据以下建议修改的代码：约翰·科米洛并进行其他调整：

\documentclass[11pt,letterpaper]{article}

\usepackage{tikz}
\usetikzlibrary{backgrounds, calc, shadows, shadows.blur}

\usepackage{graphicx}

\pgfmathdeclarerandomlist{MyRandomColors}{%
    {red}%
    {red!25}%
    {magenta}%
    {magenta!25}%
    {olive}%
    {olive!25}%
    {brown}%
    {brown!10}%
    {violet}%
    {violet!25}%
    {gray}%
    {purple}%
    {yellow}%
    {orange}%
    {orange!25}%
    {cyan}%
    {green}%
}%

\newcommand*{\GridSize}{20}

\newcommand*{\ColorCells}{%
    \foreach \y in {1,...,\GridSize} {
        \foreach \x in {1,...,\GridSize} {
            \pgfmathrandomitem{\RandomColor}{MyRandomColors}
            \draw [fill=\RandomColor, fill opacity=0.2, draw=none, ultra thick]
                (\x-1,\y-1) rectangle (\x,\y);
        }%
    }%
}%

\listfiles
\begin{document}
\pagestyle{empty}
\begin{tikzpicture}
\coordinate (Origin) at (0,0);
    \begin{scope}[scale=0.8,ultra thick,olive!45]
        \ColorCells
        \draw (0, 0) grid (\GridSize, \GridSize);
        \coordinate (input);
    \end{scope}

\node[rotate=90,above right] at ($(current bounding box.south east)+(-1,1)$)
      {\textcolor[rgb]{0.01,0.50,1.00}{\fontsize{50}{120}\selectfont{\textbf{the name of the course}}}};
          \node[above right] at ($(current bounding box.south west)+(1,1)$)
      {\fontsize{50}{120}\selectfont{name of authorities}};
\end{tikzpicture}
\end{document} 

Answer 1

我对你的代码做了一些修改

1. 它与current page引用一起工作。
2. ColorCells(1cm x 1cm) x scale已被修改为接受两个参数：xgridsize 和 ygridsize，它们是要绘制的水平和垂直单元格的数量。
3. 文本节点是参照current page而不是 来放置的current size box。
4. 替换\textcolor...\fontsize...\selectfont为node font和text选项来选择字体就像 TiKZ。

完整代码如下：

\documentclass[11pt,letterpaper]{article}
\usepackage{libertine}
\usepackage{tikz}
\usetikzlibrary{backgrounds, calc, shadows, shadows.blur}

\usepackage{graphicx}

\pgfmathdeclarerandomlist{MyRandomColors}{%
    {red}%
    {red!25}%
    {magenta}%
    {magenta!25}%
    {olive}%
    {olive!25}%
    {brown}%
    {brown!10}%
    {violet}%
    {violet!25}%
    {gray}%
    {purple}%
    {yellow}%
    {orange}%
    {orange!25}%
    {cyan}%
    {green}%
}%

\definecolor{titlecolor}{rgb}{0.01,0.50,1.00}

\newcommand*{\GridSize}{20}

%#2-Gridsizex
%#3-Gridsizey
\newcommand*{\ColorCells}[2]{%
    \foreach \y in {1,...,#1} {
        \foreach \x in {1,...,#2} {
            \pgfmathrandomitem{\RandomColor}{MyRandomColors}
            \draw [draw=olive!45,fill=\RandomColor, fill opacity=0.2, ultra thick]
                ([shift={(\x-1,\y-1)}]current page.south west) rectangle ++(1cm,1cm);
        }%
    }%
}%

\listfiles
\begin{document}
\pagestyle{empty}
\begin{tikzpicture}[remember picture,overlay]
    \begin{scope}[scale=0.8,ultra thick,olive!45]
        \ColorCells{35}{27}
        \coordinate (input);
    \end{scope}

    \node[rotate=90, above right, 
         node font=\fontsize{70}{90}\selectfont\bfseries\sffamily, 
         text=titlecolor] at ($(current page.south east)+(-1,1)$)
         {the name of the course};
    \node[above right, 
         node font=\fontsize{40}{90}\selectfont\bfseries\sffamily,   
         text=titlecolor!20!black] at ($(current page.south west)+(1,1)$)
         {name of authorities};
\end{tikzpicture}
\end{document} 

结果如下：
