Thanks for the reply.

With one file, it is working correctly. Now I get the following error
messages which are different from earlier "file not found ones".

(eog:8368): Gtk-CRITICAL **: gtk_tree_model_get_iter: assertion
`path->depth > 0' failed

(eog:8368): Gtk-CRITICAL **: gtk_list_store_get_value: assertion
`VALID_ITER (iter, list_store)' failed

(eog:8368): GLib-GObject-WARNING **:
/build/buildd/glib2.0-2.20.1/gobject/gtype.c:3940: type id `0' is

(eog:8368): GLib-GObject-WARNING **: can't peek value table for type
`<invalid>' which is not currently referenced
Segmentation fault

So any suggestions?
my code:
print "Aum Amriteshwaryai Namaha"

import Image

imagePath = "/home/suresh/EE241/book_images_3ed/ch03/"

im34 = Image.open(imagePath + "breast_digital_Xray.tif")
im35 = Image.open(imagePath + "DFT_no_log.tif")

def neg(x):
    return 255-1-x

import math

def logtr(x):
    y = math.log(1+x,10)
    print y
    return y*100

im34x = im34.point(neg)

im35x = im35.point(logtr)
