Sorry for not replying sooner, I was on vacation last week. By doesn't work
I mean returns the following error message:

TypeError: too many arguments to QPixmap(), 0 at most expected

 Anyway, I found out why the code doesn't work: scipy.toimage returns a PIL
image object, not a QImage, silly me. The
function converting a scipy array into a QImage is not in the scipy library,
but in Qwt: qwt.toQImage. The following code
does work:

import scipy
import qwt
from qt import *

# imgList is a list of scipy arrays
pixmapList = [ QPixmap(qwt.toQImage(img)) for img in imgList ]

The typo in my first post was only in the post, not in my code, I used "from
scipy import *" there, just
thought it'd be clearer here to add the module name.
