Finding bPoint for RPoint and the other way around



  • Is there any less “loopy” way to do these?
    (if there is none, then it sucks. it's slowing down my super-duper-fancy unpublished scripts)

    def getPointFromBPoint(bPoint):
        """Returns RPoint that is an equivalent to given RBPoint"""
        glyph = bPoint.getParent().getParent() # Normally I use CurrenGlyph()
        onCurvePointsContours = [[p for p in c.points if p.type != "offcurve"] for c in glyph ]
        for i_c,c in enumerate(onCurvePointsContours):
            if bPoint.getParent().index == i_c:
                for i_p,p in enumerate(c):
                    if bPoint.index == i_p:
                        return p
                        
    def getBPointFromPoint(point):
        """Returns RBPoint that is an equivalent to given RPoint"""
        glyph = point.getParent().getParent() # Normally I use CurrenGlyph()
        onCurvePointsContours = [[p for p in c.points if p.type != "offcurve"] for c in glyph ]
        for i_c,c in enumerate(onCurvePointsContours):
            if point.getParent().index == i_c:
                for i_p,p in enumerate(c):
                    if point == p:
                        return glyph[i_c].bPoints[i_p]
    

    Cheers

    hello @RafaŁ-Buchner,

    you can get a point from a bPoint directly. not sure about the other way around.

    def getPointFromBPoint(bPoint):
        return bPoint._point
    
    def getBPointFromPoint(point):
        onCurvePointsContours = [[p for p in c.points if p.type != "offcurve"] for c in point.glyph]
        for ci, c in enumerate(onCurvePointsContours):
            if point.contour.index == ci:
                for pi, p in enumerate(c):
                    if point == p:
                        return glyph[ci].bPoints[pi]
    
    # testing
    glyph = CurrentGlyph()
    bPoint = glyph[0].bPoints[0]
    point = getPointFromBPoint(bPoint)
    bPoint2 = getBPointFromPoint(point)
    print(bPoint)
    print(point)
    print(bPoint2)
    print(bPoint == bPoint2)
    

    note that getParent() is deprecated – you can get parent objects as attributes now: point.contour, point.glyph etc.

    good luck!

    from fontParts.fontshell import RBPoint
    
    g = CurrentGlyph()
    c = g[0]
    p = c.segments[0].onCurve
    
    # point to bPoint
    bp = RBPoint()
    bp._setPoint(p)
    bp.contour = c
    
    print(bp)
    
    # bPoint to point
    print(bp._point == p)
    


  • Thanks!!!!
