Hi there
I'm trying out the new mesh_as_bitmap writer option (current svn),
because gv and printer disagree with evince about the pdfs I generate.
I use g.writeEPSfile() and such on a graph instance g which inherits
from canvas.
Friendly python says
g.writeEPSfile(__file__[:-3],mesh_as_bitmap=1)
File "/home/mjg/lib/python/PyX-git/pyx/canvas.py", line 285, in
wrappedindocument
d = document.document([document.page(self, **kwargs)])
TypeError: __init__() got an unexpected keyword argument 'mesh_as_bitmap'
I suspect the culprit in the following snippet from canvas.py. While I
can't possibly wrap my brain around ingenious code like that I reckon
that the "kwargs" it passes to the document.page constructor are rather
meant to be passed to "method", because they ultimately stem from a call
to the wrapped writer method. Making that change results in success for
my case, but I'm not sure about the full implications.

N.B.: In fact I think evince got it wrong for the (shaded, not
bitmapped) pdf. The surface looks semi-transparent with a stroked mesh.
So, I guess printer and gs are both correct here, which is not a
coincidence...
def _wrappedindocument(method):
def wrappedindocument(self, file=None, **kwargs):
d = document.document([document.page(self, **kwargs)])
self.__name__ = method.__name__
self.__doc__ = method.__doc__
return method(d, file)
return wrappedindocument
class canvas(_canvas):
"""a canvas holds a collection of canvasitems"""
writeEPSfile = _wrappedindocument(document.document.writeEPSfile)
writePSfile = _wrappedindocument(document.document.writePSfile)
writePDFfile = _wrappedindocument(document.document.writePDFfile)
writetofile = _wrappedindocument(document.document.writetofile)
