如何在 TiKz 中打印与其边框之一对齐的 \pic？

Question

以下 MWE 显示了如何绘制具有缩放比例的背景图像并向其中添加预定义的“PowerSupply”图片。这很有效，但问题是，我想要设置图片的位置需要与其边框之一对齐（取决于使用的角度）。

在这种情况下，我将图片旋转了 270°。我给出的安装位置是在\pic at (3590,2000) {PowerSupply};门下方所示墙壁的左侧。这个位置完全合适，但图片位置可能与他的中心位置对齐。因此图片显示在墙的“内部”。我想将它与北边界对齐（在这种情况下，因为角度为 270°），使其在左边几个点处。

Answer 1

您只需将一个设置anchor为节点并将设置inner sep为 0pt 即可：

\documentclass{article}
\usepackage[a4paper, margin=10mm]{geometry}
\usepackage{tikz}

\tikzset{
    PowerSupply/.pic={
        \node[anchor=east, inner sep=0pt]{\includegraphics[scale=0.09, angle=270]{powerSupply}};
    },
}

\begin{document}
\pagenumbering{gobble}
\vfill
\begin{figure}[h!]
\centering
\begin{tikzpicture}[x=0.01mm, y=-0.01mm]
    \node[inner sep=0pt] (ground_floor)   
        {\includegraphics[width=99.0mm, height=107.4mm]{groundFloor}};
    
    \begin{scope}[shift=(ground_floor.north west)]
        \draw[blue, ->, line width=1pt] (0,0) -- (10000,0);
        \draw[blue, ->, line width=1pt] (0,0) -- (0,11000);
        
        \foreach \x in {0,1000,...,9000} {
            \draw[blue, line width=1pt] (\x,-100) -- 
                node[black, above=1mm] {\tiny\x mm} (\x,100);
        }
        \foreach \y in {0,1000,...,10000} {
            \draw[blue, line width=1pt] (-100,\y) --
                node[black, left=1mm]{\tiny\y mm} (100,\y);
        }
        
        \pic at (3590,2000) {PowerSupply};
    \end{scope}
\end{tikzpicture}
\caption{Ground Floor}
\end{figure}
\vfill
\clearpage
\end{document}

为了能够自由旋转\pic，也许最好旋转\pic而不是图片中节点内的图像：

\tikzset{
    PowerSupply/.pic={
        \node[anchor=north, inner sep=0pt]{\includegraphics[scale=0.09]{powerSupply}};
    },
}

\pic[rotate=270, transform shape] at (3590,2000) {PowerSupply};

---

这种简单的符号也可以用 Ti钾直接 Z：

\documentclass{article}
\usepackage[a4paper, margin=10mm]{geometry}
\usepackage{tikz}

\tikzset{
    PowerSupply/.pic={
        \begin{scope}[scale=350]
            \draw[red, thick, line cap=round] 
                (0,0) -- (0,0.5)
                (-0.5,0.5) -- (0.5,0.5)
                (-0.5,1) arc[start angle=180, end angle=360, radius=0.5];
        \end{scope}
    },
}

\begin{document}
\pagenumbering{gobble}
\vfill
\begin{figure}[h!]
\centering
\begin{tikzpicture}[x=0.01mm, y=-0.01mm]
    \node[inner sep=0pt] (ground_floor)   
        {\includegraphics[width=99.0mm, height=107.4mm]{groundFloor}};
    
    \begin{scope}[shift=(ground_floor.north west)]
        \draw[blue, ->, line width=1pt] (0,0) -- (10000,0);
        \draw[blue, ->, line width=1pt] (0,0) -- (0,11000);
        
        \foreach \x in {0,1000,...,9000} {
            \draw[blue, line width=1pt] (\x,-100) -- 
                node[black, above=1mm] {\tiny\x mm} (\x,100);
        }
        \foreach \y in {0,1000,...,10000} {
            \draw[blue, line width=1pt] (-100,\y) --
                node[black, left=1mm]{\tiny\y mm} (100,\y);
        }

        \pic[rotate=270] at (3590,2000) {PowerSupply};
