Subject: [Image-SIG] jpeg decoder with PIL 1.1.5
Message-ID: <438F657F.40308@mcgill.ca>

Hi there,
I am trying to install PIL 1.1.5 with jpeg decoder.
I installed from RPM and also from sources the libjpeg-6b into 
/usr/local/lib.
I change the ROOT_JPEG in setup.py to point to that location.
When I install PIL 1.1.5, I get a message that the JPEG support is OK. 
But when I test it, I get a message of decoder error. Someone could help 
me? I tried by myself in python and received the same IOError message.

Thanks,
Mathieu

You should have a look at pygame or pyopengl for those kind of needs.
pygame is very simple to use but it is difficult to integrate in a 
different user interface (such as GTK).

Tkinter is your friend.

import Image, ImageTk, Tkinter

def show2(imgFile):
    im = Image.open(imgFile)
    window = Tkinter.Tk()
    window.tkIm = ImageTk.PhotoImage(im)
    window.label = Tkinter.Label(window, image=window.tkIm)
    window.label.pack()
    return window

x = show2("c:\\temp\test.tif")

# to show a new image you could always:
x.tkIm = ImageTk.PhotoImage(newImage) # an open PIL image
x.label.configure(image = x.tkIm)
x.update_idletasks()

x.mainloop()

########################

I'd probably do it as a class, with an update function to change the image

This question seems to come up regularly - so here's a quick and dirty class
that should work for displaying in Tkinter (cross-platform, although I've
only tested on Windows).

wxPython also:
http://wiki.wxpython.org/index.cgi/WorkingWithImages

I'll bet you can do it with PyQT, PyGTK and PyObjC also.

However, if you douse those toolkits, you might want to just do your 
drawing with them and not use PIL at all.

Check out matplotlib, wxPyPlot, Chaco, etc.

Found the problem:

When I blew away the PIL src and added a freshy, and rebuilt with python

Hello,

 

    I am currently trying to create PDF files using TIF or JPG files for my
input. I have written a routine 

that creates the PDF file correctly using PIL to retrieve my images. If I
run the py2exe to create my 

exe file and run the program I get an error as follows

 

==========================================

ERROR: test (__main__.CITLPDF)

------------------------------------------

Traceback (most recent call last):

  File "pdfgen.py", line 51, in test

  File "Image.pyc", line 1745, in open

IOError: cannot identify image file

 

------------------------------------------

Ran 1 test in 0.000s

 

FAILED (errors=1)

 

 

I have added my pdfgen.py file for you to look at

I have a folder in my Python24 folder named Instate

To run my file from IDLE

 

C:\Python24\Instate\pdfgen.py

 

Create folders

 

C:\Python24\Input

C:\Python24\Output

 

Create a text file in the input folder with "1" entered as the text

Name this file Pages.dat

 

Copy a JPG file to the input folder and name it Page1.jpg

 

The Pages.dat file is simply their to get the number of pages

The script reads this file then opens each page in turn and adds

The jpg to the PDF canvas

 

Please can you tell me why this works in the IDLE but not in runtime

 

Thank You

I don't know what is FLC palette, but I know that freeimage can load a
lot of image formats. If you want to try it, download freeimagepy and
let me know if it work or if I can help you modifying freeimagepy.
Or send me an example image that I make some tries.

Subject: [Image-SIG] ANN: PIL 1.1.6 alpha 1 (december 11, 2005)
Message-ID: <dngqrd$c7n$1@sea.gmane.org>

The first PIL 1.1.6 is now available from effbot.org:

    http://effbot.org/downloads

(look for Imaging-1.1.6a1.tar.gz)

Notable additions:

+ Added pixel access object.  The "load" method now returns
  an access object that can be used to directly get and set pixel
  values, using ordinary 2D array notation:

    pixel = im.load()
    v = pixel[x, y]
    pixel[x, y] = v

  If you're accessing more than a few pixels, this is a lot faster
  than using getpixel/putpixel.

+ Added buffer interface support to the Path constructor.  If
  a buffer is provided, it is assumed to contain a flat array of
  float coordinates (e.g. array.array('f', seq)).

+ Added new ImageMath module:

   http://effbot.org/imagingbook/imagemath.htm

and a bunch of bug fixes and minor tweaks.  For a more complete
list, see:

    http://effbot.org/zone/pil-changes-116.htm

Report bugs to this list or directly to me, as usual.

Message-ID: <439CAB8B.4000602@tbitc.com>

Hi
I have a mature wxpython application - only the printing of a picture 
remains.

Under the development environment the application is complete and does 
print pictures.

However the frozen version (with py2exe 063) runs until the Import 
PrintPicture line is executed and then immediately issues a VC++ Runtime 
error - This application has requested the Runtime to terminate in an 
unusual manner... etc

This is free PIL 1.1.5

Any one have a suggestion or fix for this?

Thanks

Hi,
Does PIL support saving many 2D images into one tif file. 
(I think PIL calls this a image "sequence")
It was looking into the seek() and tell() functions, but all I could find was 
about _reading_ sequences.

Subject: [Image-SIG] How to pass an image from python as C/C++ pointer
Message-ID: <200512142035.56469.hilbricht@linopus.de>

Dear readers of this list,

I am writing a softproof plugin for the open source vector drawing python 
application Skencil by Bernhard Herzog, which runs on GNU/Linux and other 
Unixes.

This softproof plugin uses the little color management suite (lcms or 
littlecms) by Marti Maria to do profile based softproofing and will show the 
softproof as an bitmap representation of the vector drawing.

lcms is written in C but provides python handles, and I could perform all 
python tests of lcms.

However, I run into a problem passing image files to lcms using python. If I 
do a test with the following file softtest.py I get the error message:
 
File "/home/tobias/Skencil-CMYK/testbed/softtest.py", line 15, in -toplevel-
    cmsDoTransform(hTransform, im, imagesave, 500990)
TypeError: argument number 2: a 'C/C++ pointer' is expected, 
'instance(<PpmImagePlugin.PpmImageFile instance at 0x40a7ba4c>)' is received

How do I pass an image file as C/C++ pointer from python to lcms?

Hi Tobias -

I did a bit of work with Marti a while back, and I ended up releasing
PyCMS - I wrapper module around the Little CMS  ICC library that also
handles all the file passing complexities and such.  Marti ended providing
his own handles as well, but they're not nearly as easy to use.

You can use PyCMS directly in your program if you like, or simply refer to
my code to see how I'm using LittleCMS.  You can find PyCMS at:

Dear Kevin,

thank you for your quick reply to my question. I noticed pyCMS and had a look
at it. But as I understood it pyCMS.py relies on pyCMSdll, and I could not
compile pyCMSdll.c on my Linux system (and cannot use the precompiled Windows
dll). 

If I adapt pyCMSdll.c for my system:
-----------------------------------------------------------------------------
/////////////////////////////////////////////////////////////////////////////
// includes
/////////////////////////////////////////////////////////////////////////////
#include "/usr/include/python2.3/Python.h"
//#include "patchlevel.h" // so we can include the Python version 
automatically in pyCMSdll.versions()
#include "/usr/include/lcms.h"
#include "/usr/include/python2.3/Imaging.h"


/////////////////////////////////////////////////////////////////////////////
// version information: update this before compiling for the versions you're 
using
/////////////////////////////////////////////////////////////////////////////
#define PYCMSVERSION        "0.0.2 alpha"
#define LITTLECMSVERSION    "1.13"
#define PILVERSION          "1.1.4"

//#ifndef PY_MAJOR_VERSION
  // before 1.5.2b2, these were not supported
//  #define PY_MAJOR_VERSION 0
//  #define PY_MINOR_VERSION 0
//  #define PY_MICRO_VERSION 0
//#endif
#define PYTHONVERSION       "2.3.5"
------------------------------------------------------------------------------

and then apply gcc on pyCMSdll.c, then I get the following error messages:

tobias at phoebus:~/pyCMS/pyCMS.0.0.2alpha$ gcc -o pyCMSdll pyCMSdll.c
pyCMSdll.c: In Funktion ?getOpenProfile?:

: undefined reference to `PyEval_SaveThread'
/tmp/ccrvq1Qz.o(.text+0x1fd): In function `pyCMSdoTransform':
: undefined reference to `cmsDoTransform'
[.....]


So this stopped me so far from using pyCMS and kept me trying the 
lcms-provided
python handles.

Yours sincerely

Subject: [Image-SIG] Place image into MySQL db.
Message-ID: <dnvc9v$brs$1@sea.gmane.org>

(Sorry - I accidentally posted to General Python...)

I have a question about PIL.

I get a 50k photo from a MySQL table, convert it to grey-scale, do some
rotations, etc.  Then I want to put it back.  It seems that after I do the
greyscale, it converts from 'JPEG' to 'RAW'.  Can anyone tell me how I
convert the image back to 'JPEG' and then insert the photo into the MySQL
database? I've tried .tostring('jpeg') but that told me it couldn't load the
jpeg encoder.

My steps are here:

>>> import MySQLdb
>>> import array, cStringIO
>>> import Image, ImageOps

>>> con = MySQLdb(db='', host='', user='', passwd='')
>>> cur = con.cursor()
>>> cur.execute('SELECT photo FROM photos')
>>> result = cur.fetchone()
>>> photo = result[0].tostring()

>>> colorImg = Image.open(cStringIO.StringIO( photo))
>>> colorImg.show()   # Shows a color image on the Win32 screen

>>> img.format
'JPEG'

>>> bwImg =imageOps.grayscale(img)
>>> bwImg.format

>>> todb = bwImg.tostring(encoder_name='JPEG')
TRACEBACK ...
IOError: encoder JPEG not available.
>>>

Any help telling me how to take the bwImg image (not the PIL object) and
placing it back into a MySQL database would be highly appreciated!

Thanks!
Dave

I don't know if PIL can do this, so this can be an annoying post, but
you can use freeimagepy that doesn't have the seek and tell functions,
(for now, because I'm working for make it more "pythonic" so I'll add
functions like those ), but it has convertToMultiPage that do what you want.
If you want, I can add that functions and send you the new versions so
you can try it for see if it work in your environment.

I know that with the last (060+) py2exe versions, there was some issues
with the call of external programs/libraries, due some internal modifies.
I think that this isn't a PIL or PrintPicture (what is this? A program,
a library?), but a py2exe problem...
I think that the better method for try to find a solution is to ask at
py2exe mailing-list.

Michele,
Thanks for your reply. Are you saying you are developping a "competing 
project" to PIL !? (I didn't understand what you meant by "annoying post" 
;-)
Whatever it is, if it's freely available I would like to take a look...
PIL *should*  support multipage-tifs !

Thanks,

"tostring" converts the pixel contents to a string buffer, much like array.tostring
and similar methods in the Python library.

if you want to save the image to an external file format, use the "save" method.
to save to a string, use a StringIO or cStringIO stream as the target:

    out = cStringIO.StringIO()
    im.save(out, "jpeg")
    data = out.getvalue()

I think I should have been a little more specific.  I have a process that 
takes a bunch of photos and stores them 'as taken' in .JPG format.  I read 
them from the database like this:

>>> cur.execute("select * from photosTMP")
>>> result = cur.fetch()
>>> for each in result:
             recno = each[0]
             img[counter] = each[1].tostring()
            counter += 1

.. do something ..

>>> for photoNum in range(0,4):
             cur.execute("insert into photo(check_transactionKEY, photo) 
values(%s, %s)", (photoNum, img[photoNum] )


Now, I want to do something to them.  Resize them to 320x240, make them 
grayscale.  Possibly a rotation.  After doing what I want to do, I want to 
insert them into another table  for permanent storage.  However, at this 
point, they seem to have lost their .JPG formatting.  That's what I wrote 
about before.  I _don't_ want to save them to a file.  Rather I want to 
insert the image into the database.  If I insert the img object, isn't that 
the PIL object, rather than just the image?  I'd really like to be able to 
put the image-only in.

I guess I could img.save(file, 'jpg') and then read the file and then insert 
it, but that seems to be a particularly in-elegant way to do it.

If someone could assist, I'd really appreciate it.

you don't have to be more specific, you just have to read the
replies you get:

    to save to a string, use a StringIO or cStringIO stream as the target:

        out = cStringIO.StringIO()
        im.save(out, "jpeg")
        data = out.getvalue()

No, of course! I'm not have time and I don't able to do it!
Like I say at freeimagepy site, I create it for work with tiff G3/G4
images into my hylafax python client.

Yes, you can find it at freeimagepy.sf.net!

Message-ID: <43A9795D.70206@suse.cz>

Hi,
in the one place where you use realloc() in PIL, you ignore its return 
value. That could lead to problems if realloc() decided to move the 
allocated block away. Although that's not a problem in your case, since 
the block can only be shrunk, new gcc still complains about it, so it 
would be a good idea to fix it.

Attached is a (trivial) patch against 20051211 snapshot.

PIL's picking up a version of _imaging built for an older version of Python.
try:

    $ python
    >>> import _imaging
    >>> _imaging.__file__

to see what file it uses.

	10.4
Message-ID: <43AE5EFB.90002@halfcooked.com>

Hi,

I've installed libjpeg using Fink on my Mac (Tiger, 10.4.3) and when I 
install PIL from source it tells me that jpeg support is OK;

"""
--------------------------------------------------------------------
--- TKINTER support ok
--- JPEG support ok
--- ZLIB (PNG/ZIP) support ok
*** FREETYPE2 support not available
--------------------------------------------------------------------
"""

But when I run selftest.py I get this error message;

"""

"""

All I've done to install libjpeg is from an admin account type;

sudo apt-get install libjpeg

Which has also instaleld the libjpeg-bin and libjpeg-shlibs.

Can anyone help?

Andy

this is the python image-sig mailing list, not a generic support forum.
if your question is related to python itself, comp.lang.python may be
a more appropriate forum:

Subject: [Image-SIG] PyCon TX 2006: Early-bird registration ends Dec. 31!
Message-ID: <43B2AB53.1000409@python.org>

Early bird registration for PyCon TX 2006 ends on December 31st,
so there are only a few days LEFT. To register, please visit:

	http://us.pycon.org/TX2006/Registration

You can still register after Dec. 31st, but the cost will go up by
US$65 (US$25 for students).

This year PyCon will feature a day of tutorials before the three days
of regular presentations.  Course outlines for all the tutorials have
been posted; see

	http://wiki.python.org/moin/PyCon2006/Tutorials

All of the PyCon tutorials are still open for new registrations, but
space is limited, and we suspect they'll all be filled up by the time
early-bird registration closes.

Don't forget to book your hotel room, too.  PyCon TX 2006 is being
held at a Dallas/Addison hotel, and we have negotiated a special low
rate:

	http://us.pycon.org/Addison/Hotels

We hope to see you in Texas!

Message-ID: <edb8963c0512281948o293b7a03ra15b42e160a9c0ff@mail.gmail.com>

I  run into the same problem as Mathieu when trying to install PIL on a Celeron
D 64 machine.  I noticed that there were two set of libjpeg.so.62.0.0 in
the  libjpeg rpm:

/usr/lib/libjpeg.so.62.0.0
/usr/lib64/libjpeg.so.62.0.0

They have different byte counts:

[liao at fc42541 halloween]$ ls -l /usr/lib64/libjpeg.so.62.0.0
/usr/lib/libjpeg.so.62.0.0
-rwxr-xr-x  1 root root 141544 Mar  2  2005 /usr/lib64/libjpeg.so.62.0.0
-rwxr-xr-x  1 root root 124696 Mar  2  2005 /usr/lib/libjpeg.so.62.0.0

I suspected that the build process used the wrong file from
/usr/lib/libjpeg.so.62.0.0,
so I removed it.   This solved my problem.  I hope this is helpful for some
people with similar problem.

cheers, Luby Liao

Hi there,
I am trying to install PIL 1.1.5 with jpeg decoder.
I installed from RPM and also from sources the libjpeg-6b into
/usr/local/lib.
I change the ROOT_JPEG in setup.py to point to that location.
When I install PIL 1.1.5, I get a message that the JPEG support is OK.
But when I test it, I get a message of decoder error. Someone could help
me? I tried by myself in python and received the same IOError message.

Thanks,
Mathieu
