I am trying to get Image.show() to work, but seem to struggle with it.

Image.show() is a funky beast. I am tempted to tell you to write a
simple helper function to save an image to a temp location and show it
using some sort of Popen command. This might be your best bet. I
personally have not got Image.show() to work past windows XP.

Subject: [Image-SIG] jpeg and embedded icc profiles
Message-ID: <4FA2A53C.3050902@incomewars.net>

Hi,

I've got some images changing their color when I open them with python.
After a lot of google I found some really old emails about embedded icc 
profiles causing problems.
The files have an Adobe (1998) profile and when I save them, all the 
colors get pale.

Is there anything i can do? Shouldn't PIL 1.1.7 copy the profiles into 
the new file or is there anything I have to do? I would love to convert 
it into no profile, but I can't find a hint how to do this. pyCMS seems 
dead and on how to use littleCMS I'm unable to find anything.

Sincerly David

Subject: [Image-SIG] problem with the library installation
Message-ID: <1336706533.51196.YahooMailNeo@web39306.mail.mud.yahoo.com>

Hello,

I'm trying to install Python Imaging Library and having troubles with graphic libraries linking on a run time.
After the installation I have:

PIL 1.1.7SETUP SUMMARY
--------------------------------------------------------------------
version ? ? ? 1.1.7
platform ? ? ?linux2 2.7.3(default,May102012,13:17:15)
? ? ? ? ? ? ? [GCC 4.4.620110731(RedHat4.4.6-3)]
--------------------------------------------------------------------
***TKINTER support notavailable
---JPEG support available
---ZLIB (PNG/ZIP)support available
***FREETYPE2 support notavailable
***LITTLECMS support notavailable
--------------------------------------------------------------------

So, it looks like there is support of JPEG and ZLIB libraries
However,

python  selftest.py
returns:

PIL 1.1.7TEST SUMMARY 
--------------------------------------------------------------------

---PIL CORE support ok
***TKINTER support notinstalled

***ZLIB (PNG/ZIP)support notinstalled
***FREETYPE2 support notinstalled
***LITTLECMS support notinstalled
--------------------------------------------------------------------


Why the libraries can't be linked in a run time?

Thanks,
Olga

	python installation
Message-ID: <CAAo39db5-+o9JgSx6pNeRrbCkv2354M8-UZ1Gfai=WpnNB+7yA@mail.gmail.com>

Hi I'm attempting to get .png support for PIL and have read the README and
some instructions on how to install PIL
here<http://ygamretuta.me/2011/05/27/install-pil-in-ubuntu-natty-python27-virtualen/>
The directions show how change the JPG_ROOT and ZLIB_ROOT to point to the
installations of these libs
I'm running the python setup.py build_ext -i command with my virtualenv
activated
When I run selftest.py I get the jpeg support working but not zlib/png
 support:

--- PIL CORE support ok
*** TKINTER support not installed
--- JPEG support ok
*** ZLIB (PNG/ZIP) support not installed
*** FREETYPE2 support not installed
*** LITTLECMS support not installed

I've checked my system through the package manager and zlib1g and
zlib1g-dev are installed

they are instaled at: "usr/include/":

/usr/include/zconf.h

/usr/include/zlib.h

/usr/include/zlibdefs.h




so I have used "/usr/include" as the ZLIB_ROOT

but when I clean setup.py and run

$ sudo python setup.py build_ext -i

again it still fails for png support

It seems to me like pointing the setup.py script to these files should work

but I'm not sure this exactly how it does work

Does anybody know what I might be doing wrong?


thanx

Doug

Subject: [Image-SIG] PIL and multiprocessing module
Message-ID: <CAOdFaDXGU-aJOBiwRqG9Ywe75-5oHb9DzfsqR89MKuyZg=DhfA@mail.gmail.com>

I was wondering if anyone has used PIL with the multiprocessing module.

I would like to do some pixel by pixel translations using the .load()
function and shared memory with the multiprocessing module.


This is the code I have so far:
def convert_to_gs_load(surf):
    width, height = surf.size
    pix = surf.load()

    for x in range(width):
        for y in range(height):
            alpha = 1
            red, green, blue = pix[x, y]
            average = (red + green + blue) // 3
            gs_color = (average, average, average, alpha)
            pix[x, y] = gs_color

def convert_to_gs_load_mp(surf):
    width, height = surf.size
    pix = surf.load()

    t1 = multiprocessing.Process(target=gs_load, args=(pix, width, 0,
height / 4))
    t2 = multiprocessing.Process(target=gs_load, args=(pix, width, height /
4, height / 2))
    t3 = multiprocessing.Process(target=gs_load, args=(pix, width, height /
2, 3 * height / 4))
    t4 = multiprocessing.Process(target=gs_load, args=(pix, width, 3 *
height / 4, height))
    threads = [t1, t2, t3, t4]

    for thread in threads:
        thread.start()

    for thread in threads:
        thread.join()

The problem is the 'pix' object is not in shared memory, so this doesn't
work. Is there a way I could use Value or Array to store the object?
