如何在 tikz 中绘制右上角修剪的矩形？

Question 1

像这样吗？

\documentclass[10pt,border=3mm,tikz]{standalone}
\usepackage{tikz}

\begin{document}
 \begin{tikzpicture}[line width=3pt]
    \draw (2.3,6.5) -- (-4.3,6.5) -- (-4.3,-6.6) -- (4.3,-6.6) -- (4.3,3.7) -- cycle;
    \draw (-.9,1.6) -- (-2.9,0) -- (-.9,-1.6);
    \draw (.9,1.6) -- (2.9,0) -- (.9,-1.6);
 \end{tikzpicture}
\end{document}

也可以尝试这些：

    \draw (1.5,3.25) -- (-2.65,3.25) -- (-2.65,-3.3) -- (2.85,-3.35) -- (2.85,1.85) -- cycle;
    \draw (-.45,.8) -- (-1.45,-.25) -- (-.55,-1.3);
    \draw ( .45,.8) -- ( 1.45,-.25) -- ( .55,-1.3);

    \draw ( .45,.8) -- ( 1.45,-.25) -- ( .55,-1.3);

Question 2

还有chamfered rectangle节点形状：

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes.misc}

\tikzset{fileshape/.style 2 args={chamfered rectangle, 
    draw, ultra thick,
    chamfered rectangle corners=north east, 
    minimum height=12mm, minimum width=10mm,
    #1, label={[text=#1]270:{\sffamily #2}}
}}

\begin{document}

\begin{tikzpicture}
\node[fileshape={gray}{code}]at (0,0) (A){$<>$};
\node[fileshape={cyan}{file.psd}]at (2,0) (B){};
\draw[thick, gray] (A)--(B);
\end{tikzpicture}

\end{document}

\end{tikzpicture}

\end{document}

Question 3

这是绘制两个图标的方法。

最初的想法是按照图式人物的曲线走。但事实证明，这并不必要，你也可以在正确的位置放一个圆圈，只要路径是封闭的。

正如一条评论内的链接所指出的那样，使用带有切角的极坐标可能会很有用。

而且比例相当大。最好的方法是使用计算器（或 tikzlib ）来调整坐标，calc而不是使用scale（详情请参阅手册）。

\documentclass[10pt,border=3mm,tikz]{standalone}
\usepackage{tikz}

\begin{document}
% ~~~ pictures ~~~~~~~~~
\tikzset{
    symb/.pic={
    \draw (1.5,3.25) -- (-2.65,3.25) -- (-2.65,-3.3) -- (2.85,-3.35) -- (2.85,1.85) -- cycle;
    \draw (-.45,.8) -- (-1.45,-.25) -- (-.55,-1.3);
    \draw ( .45,.8) -- ( 1.45,-.25) -- ( .55,-1.3);
    }
}
\tikzset{
    pers/.pic={
    \draw (1.5,3.25) -- (-2.65,3.25) -- (-2.65,-3.3) -- (2.85,-3.35) -- (2.85,1.85) -- cycle;
    \draw [fill=black] (1.05,1.95) -- (-1.95,2)  -- (-1.95,-2) -- 
    (-0.95, -2) arc [start angle=180,end angle=90,radius=1cm] --
    ++(0,0) arc [start angle=270,end angle=-90,radius=1cm] --
    ++ (0,0)  arc [start angle=90,end angle=0,radius=1cm]
    -- (2.05,-2) -- (2.05,1) -- cycle;
    }
}
 % ~~~ demo ~~~~~~~~~~~~~~~~
 \begin{tikzpicture}[line width=3pt]
    \pic at (0,0) {symb};
    \pic at (6,0) {pers};
    
    \pic at (12,-9) {pers};
 \end{tikzpicture}
\end{document}

附言：当您向圆圈添加白色轮廓时，就会发生这种情况pers：

---
\draw [fill=black,draw=white] (1.05,1.95) -- (-1.95,2)   ...
