Hallo André & Cie,

Woas isch do loos?

    def ligature(self, pt, duree, h0, h1):
        dh = 0.2
        x0 = unit.topt(pt)
        x1 = unit.topt(pt + duree)
        y00 = unit.topt(h0)
        y01 = unit.topt(h0 - dh)
        y10 = unit.topt(h1)
        y11 = unit.topt(h1 - dh)
        s = path.multilineto_pt([x0, y00, x0, y01, x1, y11, x1, y10, x0, y00])
        self.c.stroke(s)

The same with path.path(path.moveto(...), path.lineto(...), ...)
works.

Hi,

multilinto_pt is a path element, not a path. You cannot stroke path elements, for example:

    from pyx import *
    c = canvas.canvas()
    c.stroke(path.path(path.moveto(0, 0), path.lineto(1, 0)))   # works
    c.stroke(path.path(path.moveto(0, 0), path.multilineto_pt([(1, 0)])))  # works as well
    c.stroke(path.lineto(1, 0))  # fails
    c.stroke(path.multilineto_pt([(1, 0)]))  # fails as well
    c.writePDFfile()

Best,


André
