如何消除 Psvectorian 双色 Pspicture 中不雅的接缝

Question

在下面的代码中，我尝试将左侧涂成蓝色psipicture，将右侧涂成黄色；但是，图片中间出现了一条“不雅”的接缝。

\documentclass[12pt]{book}
\usepackage{pstricks,psvectorian}

\makeatletter
\def\psBoldVectorian{\@ifnextchar[\psBoldVectorian@i{\psBoldVectorian@i[]}}
\def\psBoldVectorian@i[#1]#2{%
  \rput(0,0){\psvectorian[#1]{#2}}%
  \rput(0.4pt,0.4pt){\psvectorian[#1]{#2}}%
  \rput(-0.4pt,-0.4pt){\psvectorian[#1]{#2}}%
}
\makeatother
\thispagestyle{empty}
\begin{document}

\begin{pspicture}(-5,-5)(5,8)%
\psframe[fillcolor=blue!35,fillstyle=solid](-5,-5)(0,8)
\psframe[fillcolor=yellow!75,fillstyle=solid](0,-5)(5,8)
\psframe[linecolor=white](-5,-5)(5,8)


% oiseaux
\rput[tr]{-30}(-1.3,5.15){\psvectorian[color=white,width=2.1cm]{57}}
\rput[tl]{30}(1.3,5.15){\psvectorian[color=white,width=2.1cm,mirror]{57}}
\rput[tr]{-30}(-1.3,5.15){\psvectorian[color=white,width=2.1cm]{57}}
\rput[tl]{30}(1.3,5.15){\psvectorian[color=white,width=2.1cm,mirror]{57}}
\end{pspicture}%
\end{document}

我该如何消除黑色接缝，使图片的蓝色部分与黄色部分相邻且无可见边框？代码是用 编译的xelatex。谢谢。

Answer 1

\begin{pspicture}(-5,-5)(5,8)
\psframe*[linecolor=blue!35](-5,-5)(0,8)
\psframe*[linecolor=yellow!75](0,-5)(5,8)

% oiseaux
\rput[tr]{-30}(-1.3,5.15){\psvectorian[color=white,width=2.1cm]{57}}
\rput[tl]{30}(1.3,5.15){\psvectorian[color=white,width=2.1cm,mirror]{57}}
\rput[tr]{-30}(-1.3,5.15){\psvectorian[color=white,width=2.1cm]{57}}
\rput[tl]{30}(1.3,5.15){\psvectorian[color=white,width=2.1cm,mirror]{57}}
\end{pspicture}%
