[Matplotlib-users] Using RendererAgg with windows

[jim <jl...@yv...>]

Running this script gives the results below

#! /usr/bin/env python

from matplotlib.backends.backend_agg import RendererAgg
from matplotlib.transforms import Value

dpi   = Value(100.0)

o = RendererAgg(100,200, dpi)
gc = o.new_gc()
gc.set_foreground('k')
face = (1,1,1)
   
gc.set_linewidth(1)
o.draw_rectangle(gc, face, 0,0, 100,200)

o.draw_lines(gc, (1,100,1), (1,100,200))

o._renderer.write_png("test.png")

#*** Results from running the above ****************
# J:\>python test4.py

Running in on linux-gentoo 2004 runs just fine.  Gives the expected output 
file.

My windows setup is win2k, python2.4
I loaded numeric and numarray.  Gives the same results in either case.

I have Borland5.5 installed have build an extension with it.  Other than that 
have several other nonstock modules installed.

Running it on win98 with python 2.4 gives a different error, but much the same 
effect.

Thanks in advance
