can any good soul out there tell me why these two files are not the same
size?

import pygame
import StringIO

myimage = pygame.image.load("88keykbd.png")
buff = StringIO.StringIO()
buff.name = '88keykbd.png'
pygame.image.save(myimage, buff)

putimage = buff.getvalue()
print "buff:", type(buff), "myimage:", type(myimage), "getimage:",
type(putimage)

print len(getimage)
with open('myscrambledimage.dat', 'w') as newfile:
    newfile.write(putimage)

with open('myscrambledimage.dat', 'r') as newfile:
    getimage= newfile.read()
print len(getimage)

len(putimage) and len(getimage) are hugely different in size and I can't
see why as it is putimage that is written to file and then read back as
getimage.

Clarification on this would be immensly welcome.

Thank you in advance
