如何指定两个 RightAngleType 类型的点？

Question

\documentclass[border=10pt,pstricks,12pt]{standalone}
\usepackage{pst-eucl,pst-plot,pst-func}

\begin{document}
    
    \begin{pspicture}[showgrid](-2,-2)(2,2)
    \psset{PointSymbol=none}
    \pstGeonode[PosAngle={-135,0,90}](0,0){A}(1,0){B}(0,1){C}
    \pstGeonode[PosAngle={-135,0,90}](-1,-1){A'}(0,-1){B'}(-1,0){C'}
    \pstRightAngle[linecolor=blue, RightAngleType=suisseromand,RightAngleSize=1]{B}{A}{C}
    \pstRightAngle[linecolor=blue, RightAngleType=german,RightAngleSize=1]{B'}{A'}{C'}
    \psline(B)(A)(C)
    \psline(B')(A')(C')
    \end{pspicture}
\end{document}

问题：

如何定义RightAngleType=suisseromand和RightAngleType=german的点的位置RightAngleSize=1 基于三对 A,B,C 和 A',B',C' 的坐标？

从https://archiv.dante.de/~herbert/TeXnik/tex/generic/pst-eucl/pst-eucl.tex

但是，抱歉，我不明白！

当前版本 1.70 来自https://archiv.dante.de/~herbert/TeXnik/tex/generic/pst-eucl/pst-eucl.tex有一个可选参数RightAngleDotDistance，它被预设1为当前距离的一个因素，0.5用于德国和0.45瑞士罗曼角。将其设置为其他值，1点就可以移到参考点或从参考点移出：

\documentclass[border=10pt,pstricks,12pt]{standalone}
\usepackage{pst-eucl}

\begin{document}

\begin{pspicture}[showgrid](-2,-2)(2,2)
    \psset{PointSymbol=none}
    \pstGeonode[PosAngle={-135,0,90}](0.5,0.5){A}(1.5,0.5){B}(0.5,1.5){C}
    \pstGeonode[PosAngle={-135,0,90}](-1,-1){A'}(0,-1){B'}(-1,0){C'}
    \pstRightAngle[linecolor=blue, RightAngleType=suisseromand,RightAngleSize=1]{B}{A}{C}
    \pstRightAngle[linecolor=blue, RightAngleType=german,RightAngleSize=1]{B'}{A'}{C'}
    \psline(B)(A)(C)
    \psline(B')(A')(C')
\end{pspicture}
\begin{pspicture}[showgrid](-2,-2)(2,2)
    \psset{PointSymbol=none}
    \pstGeonode[PosAngle={-135,0,90}](0.5,0.5){A}(1.5,0.5){B}(0.5,1.5){C}
    \pstGeonode[PosAngle={-135,0,90}](-1,-1){A'}(0,-1){B'}(-1,0){C'}
    \pstRightAngle[linecolor=blue, RightAngleType=suisseromand,RightAngleSize=1,RightAngleDotDistance=1.25]{B}{A}{C}
    \pstRightAngle[linecolor=blue, RightAngleType=german,RightAngleSize=1,RightAngleDotDistance=1.5]{B'}{A'}{C'}
    \psline(B)(A)(C)
    \psline(B')(A')(C')
\end{pspicture}

\end{document}
