>>Are you sure the lists you give belong to the same image?
the greyvalues list was printed out by python script on a 3X4
sampleimage i made to check this

pixels=im.getdata()
for pix in pixels:
print pix
whereas the integers in the second list were from java cod

hi
i am getting value of a pixel of a greyscale image using PIL's
image.getdata and need to pack it as an int as below
ie greyvalues
127 , 56 , 135 , 99 , 102 , 101 , 146 , 112 , 155 , 154 , 112 , 169
should become
-4473925, -8289919, -4144960, -5789785, -5592406, -5658199 ,-3684409,
