Subject: [Image-SIG] bounce animation of an image
Message-ID: <4A763E41.2080209@al.com.au>

Hi,
I have a script that takes an image and makes it looks like it 
"bounces". Here it is:

import Image

def saveImg(p,pos):
    im = Image.open("new_logo.jpg")

    name = "new_logo." + str(p).zfill(4) + ".jpg"
    om = Image.new(im.mode,(im.size[0],im.size[1]))
    box = (0,pos,im.size[0],im.size[1])
    region = im.crop(box)
    nbox = (0,0,im.size[0],im.size[1]-pos)
    om.paste(region,nbox)
    om.save(name,"JPEG")
   

maxheight = 5.0
ratio = 2/3.
rate = 8.0
limit = 1

pos = 0
c = maxheight
p = 0
while c > limit:
    steps = round(rate/2.)
    leng = c/steps  
    for i in range(int(steps)):
        saveImg(p,pos)
        pos+=leng
        p+=1
    for i in range(int(steps)):
        saveImg(p,pos)
        pos-=leng
        p+=1
    c=c*ratio
   
But it keeps failing with a "ValueError: images do not match" when I do 
the pasting. What am I doing wrong?
Thanks for any help.
Cheers
Astan

You're passing in floating point coordinates to crop and paste, and it
appears that crop and paste doesn't necessarily agree on how big the
region is when you do that.  This is probably a buglet, but you should
use integer coordinates anyway; just change both calls to saveImg to:

      saveImg(p,int(pos+0.5))

(or do the rounding inside the function), and paste should work.

Message-ID: <f01b5ba60908030202x5287fa4el184b4d510b90555f@mail.gmail.com>

Hi,
I'm trying to calculate the statistics of a tiled tiff file, containing
image pyramids, using PIL 1.1.6. The problem is that I have no way to
exclude the pyramid levels from the calculations thus the results are not
correct. I managed to achieve the required result using GDAL, but it is
rather slow and I would prefer to use PIL. Are there any ideas?
Thanks

You forgot to mention what platform you're using, so I cannot give you
exact details, but most platforms that have prebuilt Python binaries
have special development packages available (usually called
"python-dev" or something similar).

The standard source package doesn't build under 2.5; 3.X is a reworked
version of Python, and hardly any code written for 2.X works out of
the box.  There's no way you can build a 2.5 binary using a header
file for 3.1.

I'm assuming your image is a binary (black and white only) image. In that case 
histogramming doesn't make much sense. If you want the numbers of ones and 
zeros, just do something like that:

ones = a.sum()
zeros = a.shape[0] * a.shape[1] - ones

HTH,

If you create a "P" type image, you can use the putpalette() method to 
attach your desired color table.

You can try adjusting the 'quality' keyword argument of the save() 
method to save space.
   im = Image.open('original.jpg')
   im.save('other.jpg', quality=50)
I don't know of a way to hit your 15KB target in a single shot, but 
would try various quality settings until your size target is achieved.

Hmmm, interesting. I've just given it a try with pure numpy boolean arrays. 
And that worked on my setup (Ubuntu Jaunty, Python 2.6, NumPy 1.2.1).

Maybe it's something really in the way that PIL aligns its image data that 
then is dumped into a NumPy array by plugging a header structure on top.

PS: I don't need a personal to with the list in CC. I read the list, and that 
gets sorted by my mail filter.

Note that PIL has its own histogram method (for a monochrome image,
the counts will end up in slot 0 and 255).

that may be true. But many people (including myself) have got needs for more 
in-depth analyses using the functions that e. g. NumPy offers. So I guess 
that's something that should work as well.

One of the biggest problems for the Linux community is, that (at least with 
Ubuntu) the realeases still feature 1.1.6. Also the upcoming Karmic (9.10) 
still features the 1.1.6 version, and I doubt it will be upgraded to 1.1.7 in 
time for release. I'd guess it's frozen already. So, we're going to face for 
almost another year these troubles of the 1.1.6 release out with the broad 
users of PIL. And I can understand the resistance to just go and install 
alternative versions versions past the package management on a broad number of 
systems (e. g. for universities).

That's nothing against your efforts Fredrik, that's just an explanation why 
you/we will have to face more ongoing usage of outdated package versions.

I'm OK with the operation not making much sense, I'm not OK with python
dying with a segmentation fault.

For what it's worth, I also get a segfault with a.sum():

>>> i = Image.open('/tmp/chart_bl.tif')
>>> a = numpy.asarray(i)
>>> a.sum()
Segmentation fault

That was my theory, but I worked around it rather than diving in with gdb to
find out for sure.

I've put that bi-level tiff file which causes problems up on drop.io if
anyone else wants to look at what's going wrong.  It's a pretty big file,
but bz2 compresses it down very well.

Sure, but it would still be interesting to know if the 1.1.7 changes
actually solves this specific problem, so we know if/how it can be
worked around or monkey patched.

Subject: [Image-SIG] PIL not working on Python 2.6
Message-ID: <7E94311A-FFF1-47CF-B3C5-4CBE6AA2126E@gmail.com>

I am trying to use PIL on a MacBook Pro running Leopard. I have Python  
2.6 installed from Python.org.
An intermittent Python user I am trying to work my way through  
Segaran's Programming Collective Intelligence book.

I had some problems installing PIL so eventually I followed the  
instructions from here: http://codeblogmore.com/blog/2009/01/23/installing-pil-116-python-26-leopard/
and it passed its own tests.

However, now running some code from PCI, I get the following:

---
Wrong JPEG library version: library is 70, caller expects 62
Traceback (most recent call last):
   File "cluster.py", line 174, in <module>
     drawdendrogram(clust,blognames,jpeg='blogclust.jpg')
   File "cluster.py", line 36, in drawdendrogram
     img.save(jpeg, 'JPEG')
   File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ 
python2.6/site-packages/PIL/Image.py", line 1405, in save
     save_handler(self, fp, filename)
   File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ 
python2.6/site-packages/PIL/JpegImagePlugin.py", line 409, in _save
     ImageFile._save(im, fp, [("jpeg", (0,0)+im.size, 0, rawmode)])
   File "/Library/Frameworks/Python.framework/Versions/2.6/lib/ 
python2.6/site-packages/PIL/ImageFile.py", line 493, in _save
     raise IOError("encoder error %d when writing image file" % s)
IOError: encoder error -2 when writing image file
---

This looks like a problem with PIL.
Is there a general problem with PIL and Python 2.6?
I am concurrently having a problem with ReportLab's installation which  
seems to be connected with PIL (but I will put that in a separate post).

Thank you for any help you can provide.

Christopher

Seems pretty clear, you're linking against the wrong libjpeg.

You're 100% right with that.

Subject: [Image-SIG] Convert "P" image with transparent index to "RGBA"
Message-ID: <3FAC6E0364FC4EBBA7A78E64371DD68F@efcore>

I'm trying to extract the frames of a GIF as individual images. To do so, I 
keep pasting each frame over the "running total" of the previous frames, 
because areas that do not change are transparent.

Since each GIF frame is a "P" image with a single index as transparency, how 
do we convert that into an "RGBA"? I could loop over the pixels and set the 
alpha manually, but perhaps I'm missing something obvious like:

    assert im.mode == 'P'
    im.convert('RGBA', alphaindex=n)

Hi,I'm new to python and to learn more I've been working through python
challenge.
I needed PIL a few levels ago, and encountered this error, but was able to
work around it. Now I don't see any way, and everything I try keeps giving
me the IOError: decoder jpeg not available error.

I've read a few sites where people have posted a similar problem, but there
seemed to be some dispute about how to fix it. I have tried some of the
suggested fixes, but I don't know enough about unix and python to follow
them.

I'm running OS X Version 10.5.7.

How can I fix this?

Thanks,
Ryan

Message-ID: <4A7E7370.2060809@bluewin.ch>

Hi

Using easy_install the installed egg does not work. The problem is the 
directory structure.
Currently it is like this:

PIL-1.1.7b1-py2.6-win32.egg
    EGG-INFO
    ... (here are all of the PIL files)
 


But to work correctly it should be:

PIL-1.1.7b1-py2.6-win32.egg
    EGG-INFO
    PIL
   

and all PIL files should be in PIL.

Hope that helps.

Thanks.

It's best to use a palettized image, since your data points are integers.
First, create one of the right size:

    from PIL import Image
    im = Image.new('P', (512,512))  # 'P' for palettized

Then, set the image data. You must use a flat list, so you need to flatten
your matrix:

    data = sum(matrix, [])  # flatten data
    im.putdata(data)

You also have to set the palette colors for the used indices (1 and 2). The
palette is a list of 768 ints (256*3), but it's somewhat easier to start
with a list of 3-tuples:

    pal = [(0,0,0) for i in range(256)]  # all black
    pal[1] = (255,0,0)  # juicy red
    pal[2] = (0,255,0)  # crazy green
    pal = sum(pal, ())  # flatten it
    im.setpalette(pal)

That's it. You should be able to test the result with this:

    im.show()

Aaaarghhh!!! Python Challenge? I tried that a couple of years ago and it

This means that PIL was built without JPEG support. You can try building
libjpeg and adding it to PIL. I'm not a Mac person so I can't help with the
details for that. On Windows, I just built libjpeg with its makefile, set
the location of the library and the headers in PIL's setup.py and rebuilt
PIL.

Another option would be to avoid using JPEG images. If you need to read a
JPEG for Python Challenge, just convert it to another format with some other
program.

Hi guys, 

 I load a palette image (I've attach it), with 1000 colors, and I want 
 to quantize and dithering it.

 The error is in 

   palette.putpalette(pal)

 Another, question, is this the best way of Quantize an image mapping it
 to that palette and dithering ?

 Thanks a lot!

Oops! Sorry, that should be "putpalette", not "setpalette".

Also, have a look at the PIL documentation for more nice stuff:

Subject: [Image-SIG] can't open an image in ASP application
Message-ID: <000001ca1ae1$aab123e0$00136ba0$@rr.com>

The following codes works fine when run directly in python:

 

import Image

if __name__ == '__main__':

    im = Image.open("e:\\wwwroot\\class59.jpg")

    print im.format, im.size, im.mode

 

However, when I try inserting the following code in an ASP page I get an
error that says, "im=Image.open("e:\\wwwroot\\class59.jpg") AttributeError:
'module' object has no attribute 'open'" 

 

<script LANGUAGE=Python RUNAT=SERVER>

import Image

im=Image.open("e:\\wwwroot\\cbreunion09\\class59.jpg")

Response.write(im.size)

</script>

 

When I do dir(Image) from the console I get

['ADAPTIVE', 'AFFINE', 'ANTIALIAS', 'BICUBIC', 'BILINEAR', 'CONTAINER',
'CUBIC', 'DEBUG', 'EXTENSION', 'EXTENT', 'FLIP_LEFT_RIGHT',

'new', 'open', 'os', 'preinit', 'register_extension', 'register_mime',
'register_open', 'register_save', 'string', 'sys', 'warnings'] 

 

But when I put Response.write(str(dir(Image))) inside my server script I
get:

['Image', '__builtins__', '__doc__', '__file__', '__name__'] in reply

Any clue as to what I need to do to open the image in my server script?

I noticed that a version or two ago PERSPECTIVE was added along with
AFFINE, QUAD, etc. to Image.transform. Did this make it into the 1.1.7

I'm using PIL version 1.1.7b1 and when setting the mode of this image to RGB
(http://img197.imageshack.us/img197/8961/111294.png)

img = Image.open('111294.png')
img.convert('RGB')

And it throws the following error:

When doing this same process with PIL 1.1.6 final, no error is thrown. The
image link above is the exact copy of the failing image, so you can use it
for diagnostics.

1.1.7 attempts to read and decompress the file's ICC tag, while 1.1.6
completely ignored that.  I seem to remember fixing something related
to this after the 1.1.7b1 release, but I'll double-check before
cutting the final branch (any day soon).

Subject: [Image-SIG] PIL JPEG-problem on a openSUSE 11.0 (X86-64)
Message-ID: <4A997284.3080800@schronen.de>

Hi from Germany,

I need your help.

I installed PIL without any mistakes on a openSUSE 11.0 (X86-64).
I tested it with PIL 1.1.4 - 1.1.5 and 1.1.6.
and Python 2.4.4. - 2.4.5.

I want to use it with ZOPE/Plone ...

PNG and GIF is ok - but JPEG-fotos are destroyed with stripes and 
Black/White.
I run the selftest.py - no problems.

Under the Python 2.5.2 of Suse there is no problem.

What shall I do???

Thanks from Germany
Alwin M.

Not sure what you're saying here - does it work if you build PIL under
Python 2.5.2, but not if you're building it under 2.4?  Or are you
comparing a version you built yourself with one you got from SuSE?
