Message-ID: <BANLkTimajZuuOnA6J48_S-PcGCyWaF7KGg@mail.gmail.com>

Hi, if you could help that'd be great. I know absolutely nothing about
python; I'm trying to run tutorials but they won't work! I think I installed
it wrong.

For the PIL specific problem if that's all that matters, please scroll down.

*Background*:

I'm trying to run a game tutorial I downloaded and keep getting

pygame.error: File is not a Windows BMP file

I tried putting

export VERSIONER_PYTHON_PREFER_32_BIT=yes

in terminal, but it didn't help.

I'm on Snow Leopard. I've googled the crap out of this. As far as I can
tell, the problem is usually that the SDL libraries aren't there. But... in
my /Library/Frameworks, I totally have SDL_image, SDL_mixer, SDL_ttf, and
SDL.framework.


*I decided to use PIL as a temporary workaround. *
To my code, I added...

def tobmp(img):
    from PIL import Image
    originalimage = Image.open(img)

    convertedimage = originalimage.convert('RGB')
    return convertedimage


Now I get the error, "ImportError: The _imaging C module is not installed."

So I tried like the FAQ said -

$ python -v
...
>>> import Image

But I got scary things like

>>> import Image
# /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk/FixTk.pyc
has bad mtime

And

import _imaging

 dlopen("/Library/Python/2.6/site-packages/PIL/_imaging.so", 2);
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ImportError: dlopen(/Library/Python/2.6/site-packages/PIL/_imaging.so,
2):      Symbol not found: _jpeg_resync_to_restart

   Referenced from: /Library/Python/2.6/site-packages/PIL/_imaging.so
   Expected in: flat namespace
 in /Library/Python/2.6/site-packages/PIL/_imaging.so



:( If you have any ideas, I'd really appreciate it! Thanks!

We'll need some more info to help:

Which OS version?
Python version and how did you install it?
PIL version and how did you install it?

But in short, yes, you do not have a properly installed PIL.

You might also ask about both this and the pygame issue on the pythonmac 
list:

Personally, I always use the python.org installer for Python, then often 
third party package binaries are available. Peruse the python-mac list 
for far more discussion of the trade offs than you'll ever want to read....

But anyway, if you only want to run things on your own machine, then the 
Apple Python should be fine.

Did you get any error messages or anything? I'm not sure that distutils 
is going to find fink-installed libraries without some tweeking. I also 
thought there was more than one extra lib needed, but maybe not these days.

Anyway, take a careful look at the output to look for hints of problems.

I also like to do:

python setup.py build
sudo python setup.py install

so I can see what happens during build, and there is no need for sudo 
for the build step.

something is -- the standard lib doesn't have support for images -- PIL 
is the most widely used, and a nice choice.

I don't think PIL supports 3.* yet -- if you want the python.org python, 
use 2.7.

There are binaries for PIL here:

http://www.astro.washington.edu/users/rowen/python/

you want: PIL-1.1.7-python.org-32bit-py2.7-macosx10.3.dmg

Which is compatible with the 32 bit python.org binary.

If you need 64 bit, then you'll need to build yourself.

odd -- I thought fink put its stuff in /sw/...

you need that for drawing text on an image. there is a freetype lib 
provided by Apple, I thought it worked with PIL.

That's odd, given the note above, so I don't knwo what to say -- there 
is sometest code youi can runin the PIL distro, you might try that for a 
hint.

Hey! Thanks for your reply.

I have OSX 10.6.7, Python comes on the mac, so I didn't install it. It's
2.6.1. I installed PIL like this:

fink install libjpeg
curl -O http://effbot.org/media/downloads/Imaging-1.1.6.tar.gz

tar -xzf Imaging-1.1.6.tar.gz
cd Imaging-1.1.6
sudo python setup.py install

If you have any ideas, please let me know. I also had a question; is PIL
required for python to use images that aren't .bmps? Sorry, I'm totally new.
Thanks again if you reply!! :)

Hi,

I installed python 3.2 but with I try to run things with python3 I get a
symbol not found error for PyCObject_asVoidPtr... whatever that is... so I'm
going to stick with python.

Hmmm, okay. I tweaked the PIL install, then reran it, and made some
progress. In setup.py I changed *JPEG_ROOT = None* to *JPEG_ROOT =
libinclude("/usr/local")*

Hmm, the readout seems okay, though I don't know what FreeType2 is -

--- TKINTER support ok
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok

*** FREETYPE2 support not available
--------------------------------------


jpgs work now! But pngs still don't. "Unable to load background.png". The
png is definitely there; I've tried it on like six different ones ><.

Thanks for taking the time to look at this!!!!!!!!!!!!!!!!!!!

I'm unable to build PIL with JPEG and PNG support in Ubuntu 11.04. I
posted this to http://ubuntuforums.org/showthread.php?t=1751455 on
Friday but have received no responses.

We build our Python webservices in a virtualenv with all external
packages stored locally. This gives us reproducible results on a
variety of Linux distros, Mac, and Windows, both for developer
machines and production boxes.

Here's a repro case in a clean virtual machine.

$ sudo apt-get install python-virtualenv
$ virtualenv --no-site-packages ~/venv
$ source ~/venv/bin/activate

$ mkdir -p ~/PIL ~/temp/site-packages
$ export PYTHONPATH=~/temp/site-packages/
$ cd ~/PIL
$ wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz

$ sudo apt-get build-dep python-imaging
# sets up zlib1g-dev, libfreetype6-dev, libjpeg62-dev, liblcms1-dev, ...

$ easy_install -v --install-dir ~/temp/site-packages --find-links ~/PIL\

PIL is know to have issues with setuptools, and, I think virtualenv. See 
this:

http://pypi.python.org/pypi/Pillow/1.6

The first thing I'd try is a straight:

setup.py build

install, without virtualenv

That will tell you whether it is a setuptools and/or virtualenv issue.

Some googling will get you other hints, or maybe it's as simple as:

easy_install pillow

-HTH,

   - Chris

PIL isn't safe for use with easy_install. I hope that Naoki's post about  
the x86_64 libraries has helped as this came up recently.

For virtualenv's the best choice, however, is to use the Pillow fork of  
PIL which runs fine with easy_install or pip. Oh, and try to avoid  
"activate" unless you're very confident of what you're doing.

The alternative is to use the MacPorts version which is 64-bit only but  
which for which many packages exist as ports:

sudo port install py27-pil

This puts Python in /opt/local/bin and allows easy management of different  
versions. It will automatically install any dependencies such as lib-JPEG  
and lib-freetype. As it provides a mechanism for upgrading existing  
packages I prefer this over the binary installs. Apple virtually never  
updates the subsystem between OS releases.

Hi,

I'm processing thumbnails with python but one thing I need to do is to
auto-adjust an image for the "best" colors. I am using ffmpeg to get
thumbs three seconds into a video, sometimes  the image is too dark.
Normally I'd go into something like the windows program Irfan View and
do "Auto Adjust Colors", but I need a command-line solution to
processes hundreds of images in a loop. I'm using Ubuntu and Python.
Is there a way in PIL I could do this?

thanks,

Lee G.

Hi Lee,

assuming you can write the correct image processing algorithm or find a  
suitable filter you can do this in PIL. However, you mind try applying  
filters directly in ffmpeg before you create a thumbnail.

Thanks, Charlie et al. Ultimately, what I ended up doing was
symlinking libjpeg.so and libz.so into /usr/lib, as earlier versions
of Ubuntu did:

$ pushd /usr/lib
$ sudo ln -s i386-linux-gnu/libjpeg.so libjpeg.so
$ sudo ln -s i386-linux-gnu/libz.so libz.so

Message-ID: <20110518102657.42950@gmx.net>

Hello,

I just installed PIL on my mac osx 10.6.6 under python 2.6.6 and
tried one of your first examples (slightly modified). I tried following
script:

import Image
import PSDraw
im = Image.open("testplot.eps")
title = "lena"
box = (1*72, 2*72, 7*72, 10*72) # in points

ps = PSDraw.PSDraw() # default is sys.stdout
ps.begin_document(title)
# draw the image (75 dpi)
ps.image(box, im, 75)
ps.rectangle(box) 

# draw centered title
ps.setfont("HelveticaNarrow-Bold", 36)
w, h, b = ps.textsize(title)
ps.text((4*72-w/2, 1*72-h), title) 

ps.end_document()


but then I get the error:

Traceback (most recent call last):
  File "/Users/Johannes Radinger/Desktop/Python Scripts/test.py", line 10, in <module>
    ps.image(box, im, 75)

Hi Johannes,

have you got Ghostscript installed on your system? It looks like you are  
getting an error because PIL can't find it.

Hi,

I am trying to install the PIL libraries but am not sure how to. I saw in
the read me file that i should do this:

        $ tar xvfz Imaging-1.1.7.tar.gz

        $ cd Imaging-1.1.7

        $ python setup.py install

but have no idea what that means. I am running windows 7 if that makes a

Subject: [Image-SIG] Png24 to GIF image size
Message-ID: <BANLkTimvKzhM58veDbHTL_2Q+rkHQRALxQ@mail.gmail.com>

Hi All,

I'm having problems converting a png24 to a gif image. The conversion works,
it's just the gif file is very large.

The example C00000004.png is 14k. When I convert it to a gif with pil the
file is 17k (test_pil.gif). If I use a Java library the gif is only 7k (
test_java.gif). I've got about 10000000 images to process so this is quite a
big deal.

I've enclosed an example of a png that I'm trying to convert C00000004.png
and the result from my conversion with PIL (test_pil.gif) and the result
from Java conversion test_java.pil.

The Python code I'm using:

im = Image.open(path + 'C00000004.png')
im = im.convert('RGB').convert('P', palette=Image.ADAPTIVE)
im.save(path + 'test.gif','gif')

In the Java version I'm using ImageIO like this.

ImageIO.write(img, "gif", outputfile);

 Am I missing something?

Thanks in advance for any help.

Kind regards

Tom

that's ow you copile it yourself, and will only work out-of-the box on a 
*nix system

On Windows, you probably want a binary installer:

http://www.pythonware.com/products/pil/

look for the "Windows only" builds, and find one that matches your 
Python install.

I'm not speaking with authority here, but back when the "GIF patent" was 
still active, some Open Source GIF drivers didn't compress, as the 
compression was the patented part of the format.

So that _may_ be the case here.

Nah, Unisys patented the format which essentially uses a 256 colour  
palette for compression. LZW compression doesn't make much difference on  
this file.

I *think* the problem is you are not creating the palette very  
intelligently there are only 20 colours in the palette.

Dear Wen,

I find the e-mail is missing a lot of information. That said there is  
known issue with JPEGs when they are geometrically translated. If possible  
it is much better to work with the original bitmap.

Subject: [Image-SIG] Codes with image does do not run
Message-ID: <558224.9311.qm@web24003.mail.ird.yahoo.com>

Hi: 

I am learning Python on my own using a " Guide to Programming with Python" 
book.?Author of the book is Micheal?Dawson and I am using version 2.3.5 of 
python. ?When I try to run the code?I do?not get required results. The picture 
could not be loaded. I get trackback message regarding undefined module.The 
example from the book is as follows:

from liveswires import games

games.init(screen_width = 640, screen_height = 480, fps = 50)
wall_image = games.load_image("wall.jpg", transparent = False)
games.screen.background = wall_image

games.screen.mainloop() 

Can anyone please assist me. 

Thank you

Dear Sikhumbuzo,

I suspect the problem has nothing to do with PIL, the Python Image  
Library. Have you installed the "liveswires" package you mention?  
Presumably to book comes with a CD containing the software. Otherwise we  
need to know the precise error you are getting.

By the way Python 2.3 is very old and not supported you should consider  
updating to Python 2.7 if possible.
