This is a trivial question, but I still don't know how to do it.  I've started up "ipython --pylab" and then:

import skimage.io as io

c = io.imread('cameraman.jpg')

io.imshow(c,'qt')

and this gives me an image in a window labelled "skimage". (I'm using Ubuntu 12.04). But how do I close this window from the console? I've tried:

plt.close('skimage')

plt.close()

plt.close('all')

plt.close(1)

none of which have any effect. I can of course close them with the mouse, but that seems a little inelegant. Is the method to "close" the window in another package entirely?

Thanks!
