Public bug reported:
Binary package hint: python-imaging
PIL 1.1.6-3ubuntu1 fails when operating on an png file from its parser() method
with
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.6/dist-packages/PIL/Image.py", line 961, in histogram
self.load()
File "/usr/lib/python2.6/dist-packages/PIL/ImageFile.py", line 189, in load
s = read(self.decodermaxblock)
File "/usr/lib/python2.6/dist-packages/PIL/PngImagePlugin.py", line 365, in
load_read
return self.fp.read(bytes)
File "/usr/lib/python2.6/dist-packages/PIL/ImageFile.py", line 300, in read
data = self.data[pos:pos+bytes]
TypeError: 'NoneType' object is unsubscriptable
this python script will expose the bug:
#!/usr/bin/env python
import PIL.ImageFile
imgfile = open('foo.png')
p = PIL.ImageFile.Parser()
while 1:
data = imgfile.read(1024)
if not data:
break
p.feed(data)
img = p.close()
img.histogram() # simple operation on PIL.Image object, should work but fails
on png files
Attached is a patch that fixes this, a lack of any bug
tracker/development contact for python-imaging upstream necessitates it
being here. Bug exists on 9.04 definatly
