[sage-edu] Image processing
I'm trying to do image processing in Sage, and so far I have been able
to do something like this:
import sympy.thirdparty
pyglet = sympy.thirdparty.import_thirdparty('pyglet')
from pyglet import image
fimg = open('.jpg','rb')
img = image.load('hint.jpg',fimg)
w,h = img.width, img.height;
w,h
I don't want to display the images in Sage, just be able to manipulate
them (add noise, etc.)
Is there another way, like importing pil directly?

PIL is an optional package:
http://www.sagemath.org/packages/optional/
At some point I plan on working on SAGE and PIL but not
this semester probably.

[sage-edu] Re: Image processing
I just got pyglet to do what I want, it is pretty easy to use and well
documented. Since it is already in the standard distribution, as part
of sympy, would it not make sense simply making it more
straightforward to import?
