[Matplotlib-users] imshow smoothing

[Michael H. <mh...@us...>]

Running the test script below gives me the image I have attached,  
which looks like it has been smoothed.

Does imshow perform some sort of smoothing on the data it displays?   
If so, is there a way to turn this off?

#!/usr/bin/env python

from pylab import *

data = array([[1,2,3,4],[5,6,7,8]])
imshow(data,interpolation=None)
savefig('output.png')
close('all')
