[Numpy-discussion] Use of fromfile

I've just started to use numarray as I have an imaging program I want to
port. I noticed in the differences document that one can read in data
using fromfile into an array. This is a great savings over using the
standard , string to integer floats. For some strange reason I can't
get it to work correctly with my interferometer file (512,512) array. So
I made up a small set of data in a file.(Attached test.txt).
The code I used was simple,
inp = open('c:/transfer/test.txt','r')
with the following error message(s)
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
File "C:\Python22\Lib\site-packages\numarray\numarray.py", line 380,
ValueError: Not enough bytes left in file for specified shape and type
Well I thought maybe Int32 is not the correct specification so I tried
Int16 and Int8. These both worked but the numbers read in were wrong.
So what am I not understanding here?
