TikZ - 裁剪正方形环

Question

我尝试创建下面的图片，但没有成功。

我就是这么做的。

\documentclass[border=10pt]{standalone}
\usepackage[x11names]{xcolor}
\usepackage{tikz}
\usetikzlibrary{calc,intersections,patterns,knots}
\usepackage{adjustbox}

\begin{document} 
\pagecolor{LightSkyBlue1!30}

\begin{tikzpicture}[line join=round,line cap=rounded]
\coordinate[label=left:] (A) at (0,2);
\coordinate[label=right:] (B) at (0,0);
\coordinate[label=left:] (O) at (0,1);
\fill[Cyan4] (-.175,-.175) rectangle (9.175,2.175);
\begin{knot}[clip width=2,clip radius=0cm]
    \strand[white,line width=0.1cm,double=Cyan4,double distance=.15cm,even odd rule] (-.175,-.175)--(1,1)--(-.175,2.175)
    (1,0)--(2,1)--(1,2)--(0,1)--cycle
    (2,0)--(3,1)--(2,2)--(1,1)--cycle
    (3,0)--(4,1)--(3,2)--(2,1)--cycle
    (4,0)--(5,1)--(4,2)--(3,1)--cycle
    (5,0)--(6,1)--(5,2)--(4,1)--cycle
    (6,0)--(7,1)--(6,2)--(5,1)--cycle
    (7,0)--(8,1)--(7,2)--(6,1)--cycle
    (8,0)--(9,1)--(8,2)--(7,1)--cycle
    (9.175,2.175)--(8,1)--(9.175,-.175);
\end{knot}
\draw[ultra thick,Cyan4] (-.2,-.2) rectangle (9.2,2.2);
\begin{scope}[even odd rule]
\path[pattern=crosshatch dots,pattern color=Cyan4] 
(-.175,-.175) rectangle (9.175,2.175)
(-.5,-.5) rectangle (9.5,2.5) ;
\end{scope}

\end{tikzpicture}

\end{document}

如何创建原始图像？

Answer 1

非常快速的目测解决方案

\documentclass[tikz]{standalone}
\usetikzlibrary{shapes.geometric}
\begin{document}
\begin{tikzpicture}
\clip[postaction=fill] (0,-2) rectangle (8,2);
\foreach\x in{1.5,0,-1.5}{\foreach\y in{-4,...,4}{\draw[white,thick](0,\x+ 0.1*\y)--++(8,0);}}
\foreach \x in {0,...,8}{
  \node[diamond,minimum size=1.5cm] (n-\x) at (\x, 0) {};
  \draw[draw=white,double=black, double distance between line centers=2mm,line width=1mm] 
  ([shift={(-135:3mm)}]n-\x.east)--(n-\x.east)--(n-\x.north)--([shift={(45:5mm)}]n-\x.west)
  ([shift={(-135:5mm)}]n-\x.east)--(n-\x.south)--(n-\x.west)--([shift={(45:2.2mm)}]n-\x.west);
  \draw[thick] ([yshift=0.21cm]n-\x.north) -- ([yshift=-0.21cm]n-\x.south);
}
\draw[thick](0,0)--++(8,0);
\end{tikzpicture}
\end{document}

Answer 2

也许是更完整的选项，但也有一些棘手的元素和一些模式问题，比如在某些 pdf 查看器中的不同渲染......，但您可以进行修改以在您的文档中获得一些良好的结果。

结果：TikzEdt 查看器

结果：Firefox 查看器...{tikzpicture}[scale=1.5]
