I get anoter issue now.
How can I know if the displayed image has been zoomed or not
(I mean not on testing xlim & ylim) ?
TIA

Thanks anyway, Jouni, I fixed my issue thanks to you ;-)
You showed me that the get_?lim methods were right,
so I followed my feeling further.

Yes :-)
You only need to set extent to the const xmin/xmax & ymin/ymax
and not those you get with get_xlim & get_ylim.
Sorry for the noise.

Well..., I forgot to mention something, sorry ;-)
I already apply this trick: I use

Try:
imshow(rand(50,50))
# zoom with mouse
xlim=getp(gca(), 'xlim'); ylim = getp
Hi,
I want to keep the image zoomed to the same factor for all my images.
If I try
ipython -pylab
imshow(rand(50,50))
then zoom with the mouse and redo
imshow(rand(50,50))
the zoom factor is not kept, ie xrange/yrange are still (0,50).
How can I keep the zoom factor ?
TIA.
