With ver 1.61 it produces:

  • @jfbu, the OP refers to the black bullet indicating the intersection. – Sigur Jan 26 at 15:42
  • The Section 3.6 from pst-eucl documentation shows the same problem. Looks like a bug? – Sigur Jan 26 at 15:47
  • One way it to pass none to each point: \pstTriangle[PointSymbolC=none,PointSymbolA=none,PointSymbolB=none](0,4){C}(0,0){A}(3,0){B} – Sigur Jan 26 at 15:50

    Only the first point in the list of the three for the triangle has to be set additionally to none: PointSymbolA=none. And it makes no difference if your first point is named C – user2478 Jan 27 at 7:01

    @Herbert yes, I loaded \pstInterCC normally.... – user173875 Jan 31 at 11:11

Edit (based on @chishimotoji's comment)

Only PointSymbolA=none is enough to delete the black bullet.

But, that is strange to me since the bullet is at point C in coordinates (0,8) (note the change of units).


Pass the options PointSymbolA=none (and for other 2 points) to the \pstTriangle command.

\documentclass[border=15pt,pstricks,12pt]{standalone}
\usepackage{pst-eucl}

\begin{document}
\begin{pspicture}[showgrid](-5,-5)(10,10)
\psset{unit=2cm,PointSymbol=none,PointName=none}
\pstTriangle[%
  PointSymbolC=none,
  PointSymbolA=none,
  PointSymbolB=none
](0,4){C}(0,0){A}(3,0){B}
 %%% OR \pstTriangle[PointSymbol=none](0,4){C}(0,0){A}(3,0){B} 
\pstMiddleAB{A}{B}{I1} \pstArcOAB{I1}{A}{B}

\pstMiddleAB{C}{A}{I3} \pstArcOAB{I3}{C}{A}
\end{pspicture}
\end{document}
  • PointSymbolA=none, position " A " PointSymbolC=none, PointSymbolB=none are unnecessary... :-) – user173875 Jan 26 at 15:56
  • @chishimotoji, sorry. Could write it better? I wrote 3 lines of codes. Are you saying that only one is needed? – Sigur Jan 26 at 16:01
  • Oh no, I think there is a problem with the first position of \pstTriangle[Options](){A}... – user173875 Jan 26 at 16:08
  • @chishimotoji, I edited. – Sigur Jan 26 at 16:09

With version 1.63, available from http://archiv.dante.de/~herbert/TeXnik/tex/generic/pst-eucl/ or in the next two days with an update of the TeXLive or MikTeX:

\documentclass[border=15pt,pstricks,12pt]{standalone}
\usepackage{pst-eucl}

\begin{document}

\begin{pspicture}[showgrid](-2,-2)(2,2)
\pstGeonode[PointSymbol=none,PosAngle={0,90,180}](1.5,-1){A}(0,1){B}(-1,-.5){C}
\pspolygon[linejoin=2](A)(B)(C)
\pstTriangleIC[linecolor=red]{A}{B}{C}
\pstTriangleOC[linecolor=red]{A}{B}{C}
\end{pspicture}


\psset{unit=3cm}

\begin{pspicture}(2,2)
    \psset{PointSymbol=none,PointName=none}
    \pstGeonode(0,0){A}(1,0){B}(1,1){C}(0,1){D}
    \pswedge[fillstyle=solid,fillcolor=red](C){1}{135}{-45}
    \pstTranslation[PointSymbol=none]{D}{B}{C}[C1] 
    \pstTranslation[PointSymbol=none]{B}{D}{C}[C2]
    \pstInterLC[PointSymbol=none]{C1}{C2}{C}{B}{M1}{M2}
    \pstInterLC[PointSymbol=none]{A}{C1}{A}{M1}{M3}{M4}
    \pstInterLC[PointSymbol=none]{A}{C2}{A}{M2}{M5}{M6}
    \psarc(A){1.73205}{0}{90}
    \psline(M6)(A)(M4)
    \psdot*(C)
\end{pspicture}
\end{document}
