It depends on what precisely you mean when you say that a python variable
is a jpeg image. Do you mean that it's a string containing the contents of
a jpeg image file? So if you wrote it to disk you'd get a jpeg image file?
If that's what you mean, you can do it with PIL and StringIO. (There might
be an easier way.)
import pygame
from PIL import Image
from cStringIO import StringIO
# create an example pygame image
img = pygame.Surface((100, 100))
pygame.draw.circle(img, (255, 0, 0), (50, 50), 40)
# convert to PIL format
imgstr = pygame.image.tostring(img, RGB, False)
pimg = Image.fromstring(RGB, img.get_size(), imgstr)
# save to string
s = StringIO()
pimg.save(s, JPEG)
r = s.getvalue()
s.close()
# r is a string with the contents of a jpeg file. to confirm:
open(img.jpg, wb).write(r)
However, this doesn't seem like a very useful thing to have (and if I
needed it so badly I would just write it to disk and read it back) so I may
be misunderstanding you.

Hi all!
Is there a way to convert a pygame surface to a png or jpeg IN MEMORY
instead of saving to disk and loading again?
something like
get_screen = SCREEN.subsurface(0, 0, SCREENW, SCREENH) # grab the screen
my_image = get_screen.convert(jpeg) # now convert the image to jpeg
and now my_image is a jpeg image of get_screen
I searched the net but couldn't find any other way other than save to disk
as jpeg and reload.
Any positive OR negative help is very much appreciated.
Thanks in advance
