Thanks Jae-Joon and Friedrich
I will try out both solutions.

If you need more hard-core way of doing this,
a = np.arange(16384).reshape(128, 128)
from matplotlib.colors import Normalize
import matplotlib.cm

I think you can use the agg backend and the corresponding Canvas'es method
canvas.tostring_rgb()
. Then you can load this in PIL by Image.fromstring.
Well, I simply send you my PIL backend.
Thanks Jae-Joo
That's doing it, thought there might be an internal way within matplotlib,
but I could figure one.
I'm quite confused with the canvas, dpi, ...

You may use StringIO.
from scipy import *
from pylab import *
from PIL import Image
import cStringIO
a = arange(16384).reshape(128,128)
f = cStringIO.StringIO()
imsave(f, a, cmap=cm.summer,vmin=0,vmax=16383, format="png") # you'd
better set the format explicitly.
f.reset()
b = Image.open(f)
f.

I have a small problem how to convert an image from matplotlib to PIL
right now doing somthing like this:
--
from scipy import *
from pylab import *
from PIL import Image
a = arange(16384).reshape(128,128)
imsave( "test.png", a, cmap=cm.summer,vmin=0,vmax=
