如何用 standaloneframe 获得紧密的图表？

为了避免编写下面的代码，我需要使用提供的覆盖beamer。

令人不快的代码

\documentclass[pstricks]{standalone}
\usepackage{pst-node}

\begin{document}    

    \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        \pspolygon*[linecolor=red](A)(B)(Q)(P)
     \end{pspicture}
        
     \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        \pspolygon*[linecolor=red](A)(B)(Q)(P)
        \pspolygon*[linecolor=green](B)(C)(R)(Q)
     \end{pspicture}
        
     \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        \pspolygon*[linecolor=red](A)(B)(Q)(P)
        \pspolygon*[linecolor=green](B)(C)(R)(Q)
        \pspolygon*[linecolor=blue](C)(D)(R)}
     \end{pspicture}
        
     \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        \pspolygon*[linecolor=red](A)(B)(Q)(P)
        \pspolygon*[linecolor=green](B)(C)(R)(Q)
        \pspolygon*[linecolor=blue](C)(D)(R)}
        \pspolygon*[linecolor=yellow](D)(A)(P)(R)
     \end{pspicture}
        
     \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        \psclip{\pscircle[linestyle=none,dimen=middle](3,3){3}}
        \pspolygon*[linecolor=red](A)(B)(Q)(P)
        \pspolygon*[linecolor=green](B)(C)(R)(Q)
        \pspolygon*[linecolor=blue](C)(D)(R)}
        \pspolygon*[linecolor=yellow](D)(A)(P)(R)
        \endpsclip
     \end{pspicture}
 
\end{document}

过去，我使用如下的beamer文档类和preview包。不幸的是，代码现在不再可编译。

遗留代码

\documentclass{beamer}
\usepackage{pstricks-add}
\usepackage[active,tightpage]{preview}
\PreviewBorder=0pt
\PreviewEnvironment{pspicture}

\begin{document}    
\begin{frame}
    \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        \only<5>{\psclip{\pscircle[linestyle=none,dimen=middle](3,3){3}}}
        \only<1->{\pspolygon*[linecolor=red](A)(B)(Q)(P)}
        \only<2->{\pspolygon*[linecolor=green](B)(C)(R)(Q)}
        \only<3->{\pspolygon*[linecolor=blue](C)(D)(R)}
        \only<4->{\pspolygon*[linecolor=yellow](D)(A)(P)(R)}
       \only<5>{\endpsclip}
     \end{pspicture}
\end{frame}    
\end{document}

读了standalone令人困惑的文档（大多数句子都很难理解）后，我提出了以下想法。但是，我想修剪周围的空格。如何获得紧密的图表？

现代代码

\documentclass[beamer]{standalone}
\usepackage{pstricks-add}
\standaloneenv{pspicture}
\begin{document}
\begin{standaloneframe}
    \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        \only<5>{\psclip{\pscircle[linestyle=none,dimen=middle](3,3){3}}}
        \only<1->{\pspolygon*[linecolor=red](A)(B)(Q)(P)}
        \only<2->{\pspolygon*[linecolor=green](B)(C)(R)(Q)}
        \only<3->{\pspolygon*[linecolor=blue](C)(D)(R)}
        \only<4->{\pspolygon*[linecolor=yellow](D)(A)(P)(R)}
       \only<5>{\endpsclip}
     \end{pspicture}
\end{standaloneframe}
\end{document}

这是一个解决方法，我不知道它是否有用。我用它geometry来设置纸张尺寸，然后用\foreach和几个\ifnums 来模拟命令的行为\only（我想你可以创建一个“仅”宏）。我用 tikz 绘制了这幅图，因为我不熟悉 pstricks，但我认为同样的方法也适用于 pstricks。

\documentclass{article}
\usepackage   {geometry}
\usepackage   {tikz}

% patper dimensions, style
\geometry {paperwidth=60mm}
\geometry {paperheight=60mm}
\geometry {margin=0mm}
\pagestyle{empty}
\setlength{\parindent}{0pt}

\begin{document}
\foreach\i in {1,...,5}
{%
  \begin{tikzpicture}
  \coordinate (A) at (0,0);
  \coordinate (B) at (6,0);
  \coordinate (C) at (6,6);
  \coordinate (D) at (0,6);
  \coordinate (P) at (1,1);
  \coordinate (Q) at (5,1);
  \coordinate (R) at (3,5);
  \useasboundingbox (A) rectangle (C);
  \ifnum \i = 5
    \clip (3,3) circle (3);
  \fi
  \fill[red]      (A) -- (B) -- (Q) -- (P) -- cycle;
  \ifnum \i > 1
    \fill[green]  (B) -- (C) -- (R) -- (Q) -- cycle;
  \fi
  \ifnum \i > 2
    \fill[blue]   (C) -- (D) -- (R) -- cycle;
  \fi
  \ifnum \i > 3
    \fill[yellow] (D) -- (A) -- (P) -- (R) -- cycle;
  \fi
  \end{tikzpicture}
  \clearpage
}
\end{document}

编辑：另一个想法，更接近 OP 方法（我认为）。使用beamer和beamerposter设置纸张尺寸。我不得不对垂直间距进行一些调整，因为上面有一个令人讨厌的“毫米”空白。还有过满警告。

\documentclass[beamer]{standalone}
\usepackage[size=custom,width=6,height=6]{beamerposter}
\usepackage{tikz}

\setbeamertemplate{navigation symbols}{}
\setbeamersize    {text margin left=0cm}
\standaloneenv    {tikzpicture}

\begin{document}
\begin{standaloneframe}
\vspace*{-0.35mm}%  This number? Trial and error...
\begin{tikzpicture}
  \coordinate (A) at (0,0);
  \coordinate (B) at (6,0);
  \coordinate (C) at (6,6);
  \coordinate (D) at (0,6);
  \coordinate (P) at (1,1);
  \coordinate (Q) at (5,1);
  \coordinate (R) at (3,5);
  \useasboundingbox (A) rectangle (C);
  \only<5> {\clip (3,3) circle (3);}
  \fill[red] (A) -- (B) -- (Q) -- (P) -- cycle;
  \only<2->{\fill[green]  (B) -- (C) -- (R) -- (Q) -- cycle;}
  \only<3->{\fill[blue]   (C) -- (D) -- (R) -- cycle;}
  \only<4->{\fill[yellow] (D) -- (A) -- (P) -- (R) -- cycle;}
\end{tikzpicture}
\end{standaloneframe}
\end{document}

答案2

最后的手段受到 Juan Castaño 的回答的启发。

\documentclass[pstricks]{standalone}
\usepackage{pst-node}

\begin{document}    
\foreach \i in {1,2,3,...,5}{%        
     \begin{pspicture}(6,6)
        \pnode(0,0){A}
        \pnode(6,0){B}
        \pnode(6,6){C}
        \pnode(0,6){D}
        \pnode(1,1){P}
        \pnode(5,1){Q}
        \pnode(3,5){R}
        %
        \ifnum\i=5\relax
            \psclip{\pscircle[linestyle=none,dimen=middle](3,3){3}}
        \fi
        %
            \pspolygon*[linecolor=red](A)(B)(Q)(P)
        %
        \ifnum\i>1\relax
            \pspolygon*[linecolor=green](B)(C)(R)(Q)
        \fi
        %
        \ifnum\i>2\relax
            \pspolygon*[linecolor=blue](C)(D)(R)
        \fi
        %
        \ifnum\i>3\relax
            \pspolygon*[linecolor=yellow](D)(A)(P)(R)
        \fi
        %
        \ifnum\i=5\relax
            \endpsclip
        \fi
     \end{pspicture}}
\end{document}
