# Bug in imshow ?

Hi,

2 issues:

1/ just to remind you that I am still looking for a solution to the previously
mentioned bug in imshow (in terms of aspect='preserve').

2/ I have another problem with imshow:

When I do for example:

figure(1)
axes([-0.1,0,0.8,0.8])
myima = rand(50,50)
imshow(myima)

then it works and shows me the array with the axes partly outside the window
since the origin for the X axis is < 0

However if I do:

figure(1)
axes([0,-0.1,0.8,0.8])
myima = rand(50,50)
imshow(myima)

with this time the Y origin < 0:

then I get a SEGMENTATION FAULT

??
thanks for any help there...

Eric

I reproduce this bug with GTK and TKagg.

With DEBUG = 1 I get this (may help):

axes([0,-0.1,0.8,0.8])
myima = rand(50,50)
In [5]: imshow(myima)

FigureCanvasGTKAgg.draw
Segmentation fault
