Hi,
you may not want to deal with clipping etc. at all. Just place your
large canvas at different positions on several pages. It should harm
any PostScript device/RIP ... it'll throw away all things outside of
the printable area. Example:
from pyx import *
c = canvas.canvas()
c.text(0, 10, "This is huge!", [trafo.scale(50)])
d = document.document()
for i in range(5):
c2 = canvas.canvas()
c2.insert(c, [trafo.translate(-20*i, 0)])
d.append(document.page(c2, centered=0,
paperformat=document.paperformat.A4))
d.writePSfile("banner")
Best,
André
