Hello All and Merry Christmas,
I've found a bug and verified it with several of my
Slackware fanatics: it seems that Pil 1.1.7
Well, I'd say scanning falls under the image stuff umbrella, and the
Sane bindings are shipped with the PIL source code... I don't know
much about them, though, but I suspect this is a Python GIL issue.

wrong mailing list, this is for PIL
Added to trunk. Thanks! /F

Hi, following patch also adds Py_*_ALLOW_THREADS macros around the
sane_get_devices and sane_open calls which can take a long time especially
if network-scanners are accessed.

Hello,
I would like to down load pill version 1.1.7 for Python2.6 .
But I have Python 2.7 on my pc.
I wonder this is not a problem
If you're using PIL on Windows, you need the version that matches your
Python installation.
Will there be a version of PIL for Python 2.7?

PIL 1.1.7 works well with 2.7, out of the box. Binaries for Windows

Can somebody give an easy way to convert a image into black and white using
a given threshold..
Currently I am doing like this
image=ImageOps.grayscale(image)
for i in range(0,width):
for j in range(0,height):

Dear All,
the given image has only two level. Pixel are either black or white.

Now, I want to locate the center of whitedot.
This can be done by locating the bounding box of white dot.
I have used following algorithm
Hello!
I am trying to run an image processing script on a new server under CentOS
5.4. I have compiled and installed PIL 1.1.7 to run with Python 2.7.1. The
compile went fine. All libraries (except TKInter) were found. All 57 tests
were passed by the test script.
When I try to run my script,
The setup output looks fine, so my guess is that your script isn't
picking up the same build as the one you get when you run the test
script. Running the following command in your PIL build directory and
your script directory will tell you what files Python are using:
python -c import _imaging;

I want to get center based on density of whitepixel. basically
center where white pixel density is very high.
Also, I am applying this algorithm on every frame taken from
camera at 2fps. So I want a high speed
Thank you for the troubleshooting technique! I am still getting

this command as root and as the user who will be running it. I ran from

analyzing single molecule fluorescent events. So should be similar to
what you want, a white spot of a given intensity surrounded by noise.

I've decided to abandon the planned 1.1.8 release, including the rough
Oh, I just noticed that your mail included the SETUP SUMMARY but not
the selftest summary. Did you install the missing libraries after an
initial failed build? It could be that distutils didn't rebuild the
necessary files for you...
For a quick sanity check, in your build directory, do:
$ ls
Ah- I think we are getting somewhere...
The ZipEncode and ZipDecode files were not in the build branch at all. I
rmvd the build directory and rebuilt again according to your
instructions. I got the all-is-well summary but still no
ZipEncode/ZipDecode files created in the build directory. In
