Hallo René, >> do you mean something like the clipping done in this example: >> http://pyx.sourceforge.net/examples/drawing2/clipping.html ? > > Jein :) > > yes if the remaining of black rectangle disappears; > no otherwise.
Probably, the example is already too complex for your question because
it inserts the clipped canvas (cl) into another canvas (c). How about
the following?
from pyx import *
clippath = path.circle(0, 0, 1)
drawpath = path.line(-2, -2, 1.2, 2)
c = canvas.canvas([canvas.clip(clippath)])
c.stroke(drawpath, [color.rgb.red, style.linewidth(1.0)])
c.writeEPSfile("clipping")
c.writePDFfile("clipping")
c.writeSVGfile("clipping")
That is probably what you are aiming at.

That should not be necessary.
Best regards,
