Heyas
So I've been messing around with the PIL and PNG's and came across a
little problem with PNG's.
So just to clarify, I'm running with the standard ubuntu 8.04 python-
imaging package that installs zlib and all the other goodies that go
along to make the PIL work with PNG's nicely.
So this works fine:
from PIL import Image
x = Image.open('some.png')
x.show()
But if I try to get a bit fancier and do
from PIL import ImageFile
p = ImageFile.Parser()
p.feed(open('some.png','rb').read())
image = p.close()
image.show()
I get a traceback:
Traceback (most recent call last):
File "basic_img.py", line 9, in <module>
image.show()
File "/usr/lib/python2.5/site-packages/PIL/Image.py", line 1450, in

_showxv(self, title, command)
File "/usr/lib/python2.5/site-packages/PIL/Image.py", line 2089, in
_showxv
file = image._dump(format=format)
File "/usr/lib/python2.5/site-packages/PIL/Image.py", line 477, in
_dump
self.load()
File "/usr/lib/python2.5/site-packages/PIL/ImageFile.py", line 189,
in load
s = read(self.decodermaxblock)
File "/usr/lib/python2.5/site-packages/PIL/PngImagePlugin.py", line
365, in load_read
return self.fp.read(bytes)
File "/usr/lib/python2.5/site-packages/PIL/ImageFile.py", line 300,
in read
data = self.data[pos:pos+bytes]
TypeError: 'NoneType' object is unsubscriptable
But if all I do is change some.png to some.jpg (or gif), it works
fine. Am I doing something horribly wrong, or forget to compile
something that was supposed to be compiled for PNG support? Is it a
known bug with a fix somewhere that I just haven't found (I've
searched all over the PIL site)
Thanks
