I ported a web application to another machine, but am having a problem getting django easy thumbnails setup on another team member's machine (mac osx 10.6 snow leopard). I know it requires PIL, but am having problems getting it and perhaps its dependencies set up on the machine.
I read this post detailing how to install libjpeg on a mac, but still did not have luck. Afterwards, I tried to uninstall PIL and instead use Pillow, but still does not work:
(newenv)wsp049614wss:site-packages Admin$ pip uninstall pil
Successfully uninstalled PIL

What am I missing? How can I get easy_thumbnails to work? I did not change anything in the codebase, and easy-thumbnails works on other machines. Thanks for any ideas!
Oh no - you have the dreaded libjpeg Snow leopard issue. Basically your standard pip install of PIL doesn't work, it messes up the libjpeg C lib. There are a million blogs on this issue, this one worked for me, but you'll have to hunt around trying out various fixes.

I am upgrading pillow from version 8.3.2 to 9.1.1.
A little confused by the release notes. version 9.0.0 and above are built against libjpeg-turbo.
Does it mean we must have libjpeg-turbo installed on our servers as well?
or is it fine to stick with libjpeg-dev package we have.
The binary wheels for Pillow are statically compiled against the basic format libraries, as evident from compiled for libjpeg-turbo 2.1.3 being present in the slimmest Python container:
~ $ docker run -it python:3.10-slim-bullseye bash
root#4fb371115880:/# pip install -q Pillow
root#4fb371115880:/# python -c 'from PIL.features import pilinfo; pilinfo()'

In other words, no, you don't need to install libjpeg-turbo (or libjpeg, even) separately if you don't compile Pillow yourself.
I have Pillow working on my OS X Mavericks machine. But when I try to install it in a virtualenv, I can't seem to get JPEG support working.
Here's the summary output of pip install Pillow in the virtualenv:
--------------------------------------------------------------------

It seems I could try to edit setup.py to point to the relevant libs, but I'm new to virtualenv, and don't know where setup.py is.
EDIT:
Well, I solved it by linking from the virtualenv to the working Pillow library.
You should install libjpeg first, as the doc says:
http://pillow.readthedocs.org/en/latest/installation.html#external-libraries
libjpeg provides JPEG functionality.
Install libjpeg using homebrew: brew install libjpeg
So, my solution was to link to the working install of Pillow from the virtualenv.
I'm doing some work on a vagrant box running Ubuntu 13.04 and python 3.3. I've installed Pillow and libjpeg-dev (installing the latter first, as recommended), and when I install (or re-install Pillow, I see this:
--------------------------------------------------------------------
PIL SETUP SUMMARY
--------------------------------------------------------------------
version Pillow 2.3.0
platform linux 3.3.1 (default, Sep 25 2013, 19:29:01)
[GCC 4.7.3]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
Great! JPEG encoder recognized. Except, when I run Pillow's selftest.py script, it fails a bunch of tests and starts off with this:
--------------------------------------------------------------------
Pillow 2.3.0 TEST SUMMARY
--------------------------------------------------------------------
Python modules loaded from /usr/local/lib/python3.3/dist-packages/PIL
Binary modules loaded from /usr/local/lib/python3.3/dist-packages/PIL
--------------------------------------------------------------------
--- PIL CORE support ok
*** TKINTER support not installed
*** JPEG support not installed
--- ZLIB (PNG/ZIP) support ok
So now it's not recognizing the JPEG decoder. To make sure this isn't just a problem with selftest.py, I did my testing and sure enough I can make and manipulate .pngs but not .jpgs. I've searched around and tried some suggested solutions, including making a symbolic link to the jpg library, like so:
sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib
No dice. Anybody have an idea of something else I could try to get the jpeg decoder working? It really isn't practical for me to restrict the workflow entirely to .png.
And, this is why I need to wait 24 hours before posting questions. I needed to pay attention to the Pillow install path. It works if I create the symlink like so:
sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/local/lib/
/usr/lib wasn't in the Pillow search path, but the above is.
I've noticed that PNG images aren't displaying in Tkinter apps using ImageTk.PhotoImage in OS X Mavericks. But, GIFs and JPEGs display fine. There's no error printed or exception thrown and debugging the code shows the image is read and has the correct height & width. Here's a simplified example:
import Tkinter
from PIL import Image, ImageTk
logo_file = 'test.png'
#logo_file = 'test.gif'
class Application(Tkinter.Frame):
def __init__(self, master):
Tkinter.Frame.__init__(self, master)
self.master.minsize(width=512, height=256)
self.master.config()
self.pack()
self.main_frame = Tkinter.Frame()
self.some_image = ImageTk.PhotoImage(Image.open(logo_file))
some_label = Tkinter.Label(self.main_frame, image=self.some_image)
some_label.config()
some_label.pack(side='top')
self.main_frame.place(in_=self.master, anchor='c', relx=.5, rely=.5)
root = Tkinter.Tk()
app = Application(root)
app.mainloop()
If you use a GIF the image will be displayed, but using a PNG it will not. Again, this is only happening on OS X Mavericks, Mountain Lion works fine. I've tried re-installing (compiling PIL) with no luck, as well as trying a new virtualenv.
Is there perhaps some PNG attribute I need to set correctly when creating/saving the PNG? Or is this a bug in PIL or Tkinter or OS X?
Update to add some details
I'm using:
Python 2.7.5 (/usr/bin/python)
PIL 1.1.7 (compiled using pip)
This is on a machine that was just updated to Mavericks from Mountain Lion, and previously had PIL installed, and I haven't messed with the system Python shipped by Apple.
Update 2 Pillow setup summary
I installed Pillow 2.2.1 and it says it has PNG support:
--------------------------------------------------------------------

--------------------------------------------------------------------
I also uninstalled and re-installed libpng using brew (libpng 1.5.14). I then re-installed Pillow to make sure it built with it, though I think it uses zlib.
Update 3 trying to build Python 2.7.5
Perhaps the issue is with zlib, trying to compile Python 2.7.5 I get this:
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 _ssl
bsddb185 dbm dl
gdbm imageop linuxaudiodev
nis ossaudiodev readline
spwd sunaudiodev zlib
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
Failed to build these modules:
_tkinter
I think your problem is that your PIL was built without PNG support, or with only partial PNG support, on your Mavericks machine.
If PIL can't find both libpng and libz where it wants to, you won't have complete PNG support. And after upgrading from Mountain Lion to Mavericks, this seems to sometimes be a problem.
This may not be the same problem you're having. For example, it could be down to Apple using a buggy version of Tcl/Tk again (as they infamously did in Snow Leopard). But it's definitely worth trying.
With Pillow, and some versions of old-school PIL (but really, if you're not using Pillow, you almost definitely should be), the end of the install process gives you a friendly "PIL SETUP SUMMARY" section that shows you all the important configuration stuff.
I had the exact same problem with Pillow 2.2.1 on a locally-built Python 3.3.2. I solved it by using Homebrew to install libpng, then rebuilding Pillow:
$ brew install libpng
$ pip-3.3 uninstall pillow
$ pip-3.3 install pillow
I was experiencing the same problem and I did the following. It seems to be fixed.
sudo unistall pillow
xcode-select --install
pip install pillow
It seems to be working great. I also installed all the items below, but it seems you have it already installed
brew install libtiff libjpeg libpng webp littlecms
Did you install Pillow dependencies?
pip uninstall Pillow
brew install libtiff libjpeg webp littlecms
pip install Pillow
You will need HomeBrew to execute the brew command.
I installed Pillow from homebrew (brew install Pillow), all necessary dependencies will be installed automatically. Problem solved.
I am at wit's end. I have a working install of python 2.6.5 with numpy and scipy. I want to use it to do some simple PCA which requires importing images. Well, I figured PIL was the way to go for this. So, following a guide, I downloaded and installed libjpeg6-b. I then used the following commands
tar zxvf jpegsrc.v6b.tar.gz
cd jpeg-6b
cp /usr/share/libtool/config/config.sub .
cp /usr/share/libtool/config/config.guess .
./configure --enable-shared --enable-static
make
I moved over to where I downloaded PIL 1.1.7 and did the following:
tar zxvf Imaging-1.1.7.tar.gz
cd Imaging-1.1.7
(edit the setup.py file to find libjpeg)
python setup.py build
python setup.py install
I then try to import _imaging and I get the famous ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/PIL-1.1.7-py2.6-macosx-10.3-fat.egg/_imaging.so, 2): Symbol not found: _jpeg_resync_to_restart

I tried most/all of the solutions out there already and haven't found much success. I ran otool on my _imaging.so after I restricted my architecture to i386 and got:

for PIL 1.1.6.
I have tried switching to gcc 4.0 and compiling both libjpeg and PIL also.
Any help would be very much appreciated. Also, if you need any more information, please do not hesitate to ask.
Do you know Macports (or Fink)? The easiest way to install software and packages is via Macports. Alternatively you could have a look at the Portfiles of Macports and see how they are compiling those libs.
You can also use pip to install imaging
user easy_install to install pip
easy_install pip
pip install http://effbot.org/downloads/Imaging-1.1.6.tar.gz
Alternatively if this does not help you, I wrote an article on how to get PIL, libjpeg, _imaging to work with python 2.6 and snow leopard
