我想要的输出

Answer 1

我修改了 sty 文件：

\newcommand{\drawupperrectangles}{
    \fill[color=KlopeCedar] (0.1,8.9) rectangle (0.8,8.2);
    \fill[color=KlopeDriftwood] (0.25,8.75) rectangle (0.9,8.1);
    \fill[color=KlopeCedar] (15.2,8.9) rectangle (15.9,8.2);
    \fill[color=KlopeDriftwood] (15.05,8.75) rectangle (15.7,8.1);
}
\newcommand{\drawlowerrectangles}{
        \fill[color=KlopeCedar] (0.1,0.1) rectangle (0.8, 0.8);
        \fill[color=KlopeDriftwood] (0.25,0.25) rectangle (0.9,0.9);
        \fill[color=KlopeCedar] (15.2,0.1) rectangle (15.9, 0.8);
        \fill[color=KlopeDriftwood] (15.05,0.25) rectangle (15.7,0.9);  
}
