Hi,
I found this old thread discussing the possibility of placing un-
resampled images in PS, PDF and SVG. It was questioned weather there
were any potential users for such a feature to justify the effort. If
it makes a difference, here is one user who very much welcome it.
I need to overlay p

Hi, What is the best way to rasterize a figure into a numpy array for
further image processing? The code I have below works, but I am
wondering if there is a more convenient way.
Thanks in advance, Geoff
import pylab, numpy
fig = pylab.figure()
pylab.plot( [1, 2, 1] )
dpi = fig.get_dpi()

Ryan,
I have noticed the same issue with contourf. It seems to be a thin gap
between neighboring polygons showing through. You can turn on a thin
contour line of the same color to cover the gap:
for c in pylab.contourf( x, y, z ).collections:
c.set_linewidth( 0.1 )
Not ideal, but it wo
