使用 TikZ 和图片环境

Question

请看我的例子：

• 图片 后 蒂克兹

     \documentclass{article}
     \usepackage{color}
     \usepackage{tikz}
     \usepackage[english]{babel}
     \begin{document}
     \begin{tikzpicture}
     \path (0pt,0pt);% for adjusting to origin of entire document
     \draw[red]
     (0pt, 50pt) -- (120pt, 140pt) -- (240pt, 50pt);
     \end{tikzpicture}
     \begin{picture}(0,0)
     \color{blue}\qbezier(0, 50) (120, 140)(240, 50)
     \end{picture}
     \end{document}
  

结果：

• 图片 前 蒂克兹

      \documentclass{article}
      \usepackage{color}
      \usepackage{tikz}
      \usepackage[english]{babel}
      \begin{document}
      \begin{picture}(0,0)
      \color{blue}\qbezier(0, 50) (100, 140)(200, 50)
      \end{picture}
      \begin{tikzpicture}
      \path (0pt,0pt);% for adjusting to origin of entire document
      \draw[red]
      (0pt, 50pt) -- (100pt, 140pt) -- (200pt, 50pt);
      \end{tikzpicture}
      \end{document}
  

结果：

• 图片 没有 蒂克兹

      \documentclass{article}
      \usepackage{color}
      \usepackage{tikz}
      \usepackage[english]{babel}
      \begin{document}
      \begin{picture}(0,0)
      \color{blue}\qbezier(0, 50) (100, 140)(200, 50)
      \end{picture}
      \end{document}
  

结果：

从第三个示例中可以看出，图片环境的坐标与 TikZ 环境的坐标不同。是否可以描述蒂克兹与同一坐标系中的图形图片环境有？

Answer 1

不，坐标没有问题。问题是 tikz 默认使用边界框，而\begin{picture}(0,0)您的环境中没有边界框 picture。在第一部分中，我在 tikz 代码中使用“图片”，在其他部分中使用图片的边界框。备注：您的代码中空格放错了位置。

\documentclass{article}
\usepackage{color}
\usepackage{tikz}
\usepackage[english]{babel}
\begin{document} 
  \parindent=0pt
\begin{tikzpicture}
   \draw[help lines,step=10pt](0,0) grid (200pt,150pt);
   %\path (0pt,0pt);
    \draw[red]  (0pt, 50pt) -- (100pt, 140pt) -- (200pt, 50pt);
    \node[inner sep=0pt,anchor=south west] at (0,0){% 
    \begin{picture}(200,140)%
       \put(0,0){\line(1,0){200}} 
        \color{blue}\qbezier(0, 50) (100, 140)(200, 50)%
    \end{picture}% 
    };     
 \end{tikzpicture}%
   \begin{picture}(200,140)% 
     \put(0,0){\line(1,0){200}}
    \color{blue}\qbezier(0, 50) (100, 140)(200, 50)%
    \end{picture}           
  \begin{picture}(0,0)
    \color{blue}\qbezier(0, 50) (100, 140)(200, 50)%
    \end{picture}% 
    \begin{tikzpicture}
    \path (0pt,0pt);
    \draw[red]
    (0pt, 50pt) -- (100pt, 140pt) -- (200pt, 50pt);
    \end{tikzpicture}        
    \end{document}

更新

tikzpicture 的边界框为空的版本

\documentclass{article}
\usepackage{color}
\usepackage{tikz}  
\begin{document} 
  \parindent=0pt

\null\vspace{2cm} 

  \begin{picture}(0,0)
    \color{blue}\qbezier(0, 50) (100, 140)(200, 50)%
    \end{picture}% 
    \begin{tikzpicture}
    \draw[use as bounding box] (0,0) rectangle (0,0);     
    \path (0pt,0pt);
    \draw[red]
    (0pt, 50pt) -- (100pt, 140pt) -- (200pt, 50pt);
    \end{tikzpicture}% 
    \begin{picture}(0,0)
    \color{green}\qbezier(0, 50) (100, -90)(200, 50)%
    \end{picture}%         
\end{document} 

版本overlay

 \documentclass{article}
 \usepackage{color}
 \usepackage{tikz}  
 \begin{document} 
   \parindent=0pt

   \null\vspace{2cm} 

 \begin{picture}(0,0)
   \color{blue}\qbezier(0, 50) (100, 140)(200, 50)%
 \end{picture}% 
 \begin{tikzpicture}[overlay]
   \path (0pt,0pt);
   \draw[red]  (0pt, 50pt) -- (100pt, 140pt) -- (200pt, 50pt);
 \end{tikzpicture}% 
 \begin{picture}(0,0)
   \color{green}\qbezier(0, 50) (100, -90)(200, 50)%
 \end{picture}%          
 \end{document}

两段代码的结果是一样的。
