Hi,

I'm having a serious problem with the Python Image Library: it  
compiles fine with JPEG support, and passes the selftest.py (55  
tests), but whenever I try to open a JPEG file, I receive an error  
(AttributeError: 'module' object has no attribute '_safe_read'; see  
below).
I use Python 2.3.5 and libjpeg62 (Debian 3.1), PIL 1.1.5 (no Freetype2).
Do you have any hints how I can overcome this?

Thanks,
Bernhard Barkow

looks like a version mixup.  make sure you don't have older ImageFile
modules lying around...

Something went wrong with my previous post - try again.  I posted this query
on comp.lang.python and received a reply suggesting I try this mailing list.

I'm still wrestling with Python / Tkinter / PIL. ?I have almost got it to
work - on a Fedora Core 1 system I can now display images in a Tkinter
window. ?But I also run a Fedora Core 3 system, and when I tried the same
procedures I get the following errors:- 

[kpeter at localhost jpgTest]$ python pil_jpg.py

IOError: decoder jpeg not available 

I am running Python 2.3.4, PIL 1.1.5 on a Fedora Core 3 system. ?I know the
code is ok, as it runs quite happily under FC1 and Windows. ?I've searched
around for clues, and found a few references to this error message, but
quite frankly don't understand what they are saying. 

Searching around for files that look as if they may be the jpeg libraries I
can find 

/usr/lib/libjpeg.so.62.0.0, and a symbolic link /usr/lib/libjpeg.so.62. 

I think I somehow have to configure PIL to recognise these, but I am not
sure and anyway don't know how to do this. 
Can anyone help?

maybe you could explain what it is that you don't understand ?

(after all, if you've trouble understanding the explanations you've already
seen, posting more of the same will probably not help you...)

Fair point.  I didn't understand what I was looking for in the way of JPEG
libraries and was reluctant to risk damaging some unrelated files.

I have found a reference in
http://effbot.org/zone/pil-decoder-jpeg-not-available.htm.  Here it says that
for PIL 1.1.5 I should change the setup.py file so that JPEG_ROOT points to the
directory where the libjpeg library is installed.  In setup.py there is a  comment:-

# Use None to look for the libraries in well-known library locations.

I'm not sure where the jpeg libraries are (or what to look for).  As I said in
before, the only files I can find which look likely are

/usr/lib/libjpeg.so.62.0.0, and a symbolic link /usr/lib/libjpeg.so.62

I would have though that /usr/lib is a well known library location.
Nevertheless I tried changing the line  JPEG_ROOT = None to JPEG_ROOT =
"/usr/lib" and reran setup.py. The output was

[root at localhost Imaging-1.1.5]# python setup.py install
running install
running build
running build_py
running build_ext
--------------------------------------------------------------------

To add a missing option, make sure you have the required
library, and set the corresponding ROOT variable in the
setup.py script.

I must have jpeg libraries somewhere, as other appliations (eg GIMP and gThumb)
will show jpeg images.  But if they're not in /usr/lib, and the locate command
doesn't show any other likely candidates, how do I go about finding them?  And
if I do find them, is it literally just a case of setting the JPEG_ROOT variable?

chances are that you only have runtime libraries, and no developer files.
this would mean that applications that are linked against libjpeg will work,
but that you cannot link new applications (like PIL) against them...

try installing the "libjpeg62-dev" package (or whatever that's called on
fedora).

I found a file libjpeg-devel-6b-33.i386.rpm on the FC3 discs, so installed that.
 It appeared to create the file /usr/lib/libjpeg.so

Running setup.py install then gave

so I thought I was there - JPEG support ok!

But running my test code gave the same error message as before. 

It's midnight in London now, so I'm off to bed.  Try again tomorrow.

The tests might pick up your old, broken build.  Try installing the new library before
running the tests, or remove any traces of _imaging*.so from the Python install and
see if that fixes things.

(unfortuntely, there's no "uninstall" command in distutils...)

Success!  Though not without some drama along the way

I deleted the _imaging*.so files and reinstalled PIL - no change.  So I next
backed up and removed the entire PIL directory and reinstalled - still no
change.  Then I thought that maybe the files are created first in the setup
directory and copied across.  So I deleted all the setup files and reinstalled
from the original tarball.

This time it looked like disaster - Python didn't even get as far as Imaging,
but fell over somewhere in Tkinter with a message about Tclerror(?).  I went
back to the install and ran the setup test which seemed to complete ok - I think
it said 55 tests passed.  I reran my jpg test script, and this time it worked!

I can't recall the exact Tcl error message, and it's scrolled off screen by now,
so I just hope that it doesn't recur.  It looks as if everything is working.

Thanks for all the guidance.

Since you've mentioned this, are you looking into using setuptools and 
eggs? uninstall is one of their features.

Hi all

Can u help me for a source code of d3des encryption algorithm in python
I need it for my program.

I could find out a build which converts a source of c code into python
external module.
But it didnt give me a source code.

Can u also tell me how to retrieve a source code from external module
i.e. " .pyd " files....
Attaching herewith "pyd3des.pyd"

Thanx  & regards.

Python is case-sensitive.  "Image" and "image" are two different things.

Is there a way for me to fix this?

Ok, trying to nail the issue down I changed the Python version under Linux.

Here's the program:

    print entry[1:2]

looks like

    help(aggdraw.Draw("RGB", (1, 1)))

is enough to cause a crash.

Subject: [Image-SIG] using filters dll in Python?
Message-ID: <43F306E2.3030900@gmail.com>

Hello,

I'm trying to access the Filters-Dll provided by the filters-project 
(http://filters.sourceforge.net/index.htm).

Following the advice I got from the Python mailing list, I do this using 
ctypes (http://starship.python.net/crew/theller/ctypes/index.html).

I can seem to access the image filters now provided by the Dll because I 
can instantiate "filter-objects".

But reading and writing of images is still a problem: I don't know how I 
should read and write files because the project is not very well documented.

So, I was wondering whether there are people on this list that have some 
experience in using the filters Dll. Maybe they could sent me some 
examples of the use of the Dll with Python? Or maybe some of you have 
other suggestions as to which filter library to use?

Kind regards,
Dieter

Message-ID: <dsvae1$e3$1@sea.gmane.org>

Hi,

I have some TIFF images that use the "deflate" compression algorithm 
which unfortunately PIL (1.1.5) doesn't support.
So I'd just like to ask if there are any plans to add support for 
deflate in the foreseeable future?

Should there be test images required, I have put two examples (one rgb 
and one rgba image) over here:

Hi,

I'm looking for a library of image filters to use in course assignment 
on computer vision.

I've considered the Filter Project 
(http://filters.sourceforge.net/index.htm) and the openCV project 
(http://www.intel.com/technology/computing/opencv/). But I found the 
first lacking in documentation and the second hard to install.

Does anybody has other suggestions about which filter library I could 
use with Python? Did anybody use the first two suggestions?

Or Maybe there is some computer vision application that I can access 
trough the command line, so that I can use Python to control it?

Any suggestions are very welcome,

Dieter

Hoi,

Not knowing what you are exactly looking for, you might want to check out 
SciPy: www.scipy.org (see the filter options in the 'old' pdf version of the 
scipy tutorial at www.scipy.org/Documentation for an overview).
SciPy provides various filter options on arrays. Images can be imported, 
provided PIL is installed (which I presume anyway ;-) ).

Cheers
Christian

The documentation isn't a "real" project... You have the sources, that
are the better documentation!

Try to load the library and use the library with ctypes. Post the
problems on ctypes ml, and if you want, share your python code with the
community, like I do with freeimagepy!

I don't know if PIL will add that feature, but into the new freeimagepy
version (1.2.2), I add the convertToPil feature, so, if you want, you
can load your images with freeimagepy and convert them to PIL form make
your work. I have already tried your images and all work well..

   It' a python wrapper for FreeImage, Open Source library for developers

How work?
   It use a binary freeimage library present on the system and ctypes.

Major changes from 1.2.0:
  New convertToPil function:

   pil = i.convetToPil()

I've got a web cam, your basic run-of-the-mill variety, that purports
to be capable of VGA 640x480 still images, but only lower resolution
for video.  However, I can not figure out how to capture a VGA quality
image.  Using VideoCapture.py only enables the lower resolution
images.  My assumption is that the driver being used for the web cam
is only providing the video options.  Can anybody clue me in to how I
can capture these VGA snapshots?  I've seen the TWAIN module for
Windows, but I'd prefer a portable option.  I've Google around but
haven't come up with anything concrete yet.

FYI, I'm just getting into Python.

Back in December I wrote to the list [1] asking for help getting JPEG 
support to work with PIL on my Mac.

Well I finally got it working and thought I would share my solution with 
the list for posterity's sake.

Essentially because I'd installed libjpeg using fink it wasn't in any of 
the 'usual' library locations that PIL's setup.py was expecting. So 
after unpacking the PIL source distribution I edited the setup.py file, 
changing line 32 from;

JPEG_ROOT = None

to;

JPEG_ROOT = "/sw/lib"

And the usual python setup.py install worked like a dream.

like most PIL methods, convert returns the converted image.  try changing
your code to:

    im = im.convert('1')
    im.save('file-1bit.bmp')

putalpha(band) works only with one band at the same time, it is that? .

that is it possible (?), and how to make? .

Subject: [Image-SIG] bug in pildriver.py PASTE operation (1.1.5)
In-Reply-To: Your message of "Tue, 28 Feb 2006 03:22:44 PST."
	<du1bq4$ei7$1@sea.gmane.org> 
Message-ID: <06Feb28.134349pst."58633"@synergy1.parc.xerox.com>

The code for the pildriver.py "paste" operation currently looks like this:

    def do_paste(self):
        """usage: paste <image:figure> <int:xoffset> <int:yoffset> <image:ground>

        Paste figure image into ground with upper left at given offsets.
        """
        figure = self.do_pop()
        xoff = int(self.do_pop())
        yoff = int(self.do_pop())
        ground = self.do_pop()
        if figure.mode == "RGBA":
            self.push(ground.paste(figure, (xoff, yoff), figure))
        else:
            self.push(ground.paste(figure, (xoff, yoff)))

This seems somewhat useless -- a None value gets pushed on the stack.

More useful would be:

    def do_paste(self):
        """usage: paste <image:figure> <int:xoffset> <int:yoffset> <image:ground>

        Paste figure image into ground with upper left at given offsets.
        """
        figure = self.do_pop()
        xoff = int(self.do_pop())
        yoff = int(self.do_pop())
        ground = self.do_pop()
        if figure.mode == "RGBA":
	    ground.paste(figure, (xoff, yoff), figure)
        else:
            ground.paste(figure, (xoff, yoff))
        self.push(ground)

Otherwise you need an extraneous dup (to make a copy of the ground)
and pop (to get rid of the None) in there.

This is PIL 1.1.5 with Python 2.3.5.

Subject: [Image-SIG] read image into an array
Message-ID: <d2969d250602090503l7178c4e4r4edb127c549df376@mail.gmail.com>

Hello everyone,

I'm doing image processing on 8-bit gray color images.
This code loads the data into array:

    self.im     = Image.open("example.bmp")
    self.image  = zeros([self.im.size[0], self.im.size[1]], Int)

    i = 0
    while(i < self.im.size[0]):
      j = 0
      while(j < self.im.size[1]):
        self.image[i,j] = self.im.getpixel((i, j))
        j=j+1
      i=i+1

Is there a faster way to do it? For example using getdata() method of Image
class?
And later how I can convert above array into Image without using slow
putpixel method?

Subject: [Image-SIG] hair follicle gene expression display
Message-ID: <28300.1139885728@www072.gmx.net>

Hi,

my job at the moment is to provide a Python Script to display the different
live cycle stages of hair follicle gene expression.

Right now I try to google for this in the internet, without much success so
far. Has anyone encountered a forum thread, etc. which involves this problem
already, or has made experiences with this already?

Cheers
Juergen

Subject: [Image-SIG] Installing PIL into windows ZOPE
Message-ID: <20060216112309.15066.qmail@web30210.mail.mud.yahoo.com>

I want to install PIL into zope but I couldn't use the installation package since python that came with zope isn't register on windows. 
   
  so I installed python 2.3 seperately and I found some artical on the zope website and it said to 
   -  decompress and PIL package and move
   -  Copy the PIL folder and the pil.pth file from your Python folder into: YourZopeFolder/lib/python 
   -  Copy _imaging.pyd, _imagingtk.pyd, tk83.dll and tcl83.dll into YourZopeFolder/bin/DLLs
   -  Copy PIL folder in Zope\lib\python\PIL
   
  I did all that but I'm not sure if PIL now work with zope or not...
   
  I started importing External Script using PIL but all I get is -- 'module' object has no attribute 'Image'
   
  Can someone tell me how I can check if PIL works?
  Does anyone have a simple PIL coding I could use?

Subject: [Image-SIG] Highlight Graphic according to data
Message-ID: <20080.1140388489@www015.gmx.net>

 

Hi,

I am thinking about using the Python Imaging Library to display the life
cycle of a hair follicle gene. This life cycle is divided into four main
stages:
1. Anagen
2. Catagen
3. Telogen
4. Exogen

Gene name and corresponding life cycle stage will be stored in a csv ? file
or Excel Spreadsheet column.

In a picture of this life cycle, the corresponding gene stage should be
highlighted in some way.

The enclosed picture is a rough draft, but should give an idea how the life
cycle will look like. 

Is it possible to do this with a Python script? Will I have to store
different 'versions' of the life cylce, each one highlighting another stage?

As I am merely learning Python at the moment, it would be great to receive
tips regarding my project, thanks!

Cheers
Juergen

Subject: [Image-SIG] Putalpha on a color (r, v, b)
Message-ID: <1140436439.8957.7.camel@glux1.dux.home>

Hello,

I present myself: I'm a professor of visual arts and I live in Caen in
Normandy (France) .

I'm new with PIL, and I want to know how to put alpha channel on a color
(not simply a band) . 

putalpha(band) works only with one band at the same time, it is that? .
I would like to make a trick of the style ==> putalpha((108, 128, 199)),
that is it possible (?), and how to make? .

Thank you in advance .
