tikz 比例在 Tex 中不一致

我有下图的代码

\begin{tikzpicture}[scale=1,font=\footnotesize]
 \coordinate (A) at (0,0);
 \coordinate (B) at (0:1.5);
 \coordinate (C) at ([shift={(B)}]-50:1);
 \coordinate (D) at ([shift={(C)}]-160:1.5);
 \coordinate (E) at (240:1);
 \path ($(A)+(0.5,2)$) coordinate (A')
 ($(B)+(0.5,2)$) coordinate (B')
 ($(C)+(0.5,2)$) coordinate (C')
 ($(D)+(0.5,2)$) coordinate (D')
 ($(E)+(0.5,2)$) coordinate (E');
 \fill[left color=gray!70,right color=gray!70, middle color=gray!40, opacity=1.2] (A')--(B')--(C')--(D')--(E')--cycle;
 \fill[left color=gray!90,right color=gray!40, middle color=gray!60, opacity=1.2] (E)--(E')--(D')--(D)--cycle;
 \fill[left color=gray!90,right color=gray!40, middle color=gray!60, opacity=1.2] (C)--(D)--(D')--(C')--cycle;
 \draw[line width=0.2pt] (E)--(E')--(A')--(B')--(C')--(C)--(D)--cycle
 (C')--(D')--(E') (D)--(D');
 \draw (D)node[below]{Khối lăng trụ};
\end{tikzpicture}

当我使用选项 scale=0.7 时，图片如下图所示

该案例到底出现了什么问题？

答案1

事实上，符号坐标并没有发生变换。然而，在

 \coordinate (C) at ([shift={(B)}]-50:1);
 \coordinate (D) at ([shift={(C)}]-160:1.5);

由于 Ti 的方式，转变得到了有效的转变钾Z 解析这些。因此，您需要将这些表达式替换为

 \coordinate (C) at ($(-50:1)+(B)$);
 \coordinate (D) at ($(-160:1.5)+(C)$);

获得

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{calc}

\begin{tikzpicture}[scale=1,font=\footnotesize]

 \coordinate (E) at (240:1);
 \path ($(A)+(0.5,2)$) coordinate (A')
 ($(B)+(0.5,2)$) coordinate (B')
 ($(C)+(0.5,2)$) coordinate (C')
 ($(D)+(0.5,2)$) coordinate (D')
 ($(E)+(0.5,2)$) coordinate (E');
 \fill[left color=gray!70,right color=gray!70, middle color=gray!40, opacity=1.2] (A')--(B')--(C')--(D')--(E')--cycle;

\end{tikzpicture}
\end{document}

顺便说一句，你可以稍微简化一下你的图片，

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}[scale=1,font=\footnotesize]
 \path (0,0) coordinate (A) (0:1.5) coordinate (B)
 ++ (-50:1) coordinate (C) ++ (-160:1.5) coordinate (D)
 (240:1) coordinate (E);
 \path ($(A)+(0.5,2)$) coordinate (A')
 ($(B)+(0.5,2)$) coordinate (B')
 ($(C)+(0.5,2)$) coordinate (C')
 ($(D)+(0.5,2)$) coordinate (D')
 ($(E)+(0.5,2)$) coordinate (E');
 \fill[left color=gray!70,right color=gray!70, middle color=gray!40, opacity=1.2] (A')--(B')--(C')--(D')--(E')--cycle;
 \fill[left color=gray!90,right color=gray!40, middle color=gray!60, opacity=1.2] (E)--(E')--(D')--(D)--cycle;
 \fill[left color=gray!90,right color=gray!40, middle color=gray!60, opacity=1.2] (C)--(D)--(D')--(C')--cycle;
 \draw[line width=0.2pt] (E)--(E')--(A')--(B')--(C')--(C)--(D)--cycle
 (C')--(D')--(E') (D)--(D');
 \draw (D)node[below]{Khoi lang tru};
\end{tikzpicture}
\end{document}

还请注意，我的编辑器不处理中的特殊字符Khối lăng trụ，所以我不得不删除它们，很抱歉。
