The 1st code snippet of image_demo2.py is as follows

#!/usr/bin/env python
from pylab import *

w, h = 512, 512
s = file('../data/ct.raw', 'rb').read()
A = fromstring(s, uint16).astype(float)
A *= 1.0/max(A)
A.shape = w, h

I replaced s = file('../data/ct.raw', 'rb').read()  with s =
file('/home/jaguar/Developemnt/image_demo2.png', 'rb').read()

The image is same as in given demo example(its given in .png format)
and rest of code is also same.....
when I run it it gives the error as *" *
*A = fromstring(s, uint16).astype(float)*
*ValueError: string size must be a multiple of element size"*
WHat can be the error in program? I may asking stupid question Thanks
in advance !
Regards
Yogesh
