Subject: [Image-SIG] FYI: "Basic Motion Graphics with Python"
Message-ID: <e63mcd$sdm$1@sea.gmane.org>

just stumbled upon a very nice tutorial by Simon Yuill:

     http://yourmachines.org/tutorials/mgpy.html

this uses PIL, ffmpeg, aggdraw, PyGame, and a bunch of other tools to do 
various kinds of motion graphics in Python, including animated graphics 
and video processing.

Subject: [Image-SIG] Upsample an image
Message-ID: <BAY111-F222B4D1D3B01051B497852E1950@phx.gbl>

Hi all

When I tried downsample an image using im.resize and then upsampled it to 
get to the original size, it looked a bit blurry and lost a lot of details. 
How am I suppose to upsample it back to its original size without losing 
details? Will im.transform work?

Thanks a lot

that's expected: if you downsample an image, you lose information.  once 
lost, there's no way to get it back.

(if this wasn't the case, image compression would be a lot easier than 
it is...)

footnote: if you're e.g. implementing an image display tool, the right 
solution is to keep resampling/transforming from the same source image:

      original = Image.open(...)

      # (re)draw
      display_im = original.resize(display_size)
      render_to_screen(display_im)

instead of resizing the same image over and over again:

      image = Image.open(...)

      # (re)draw
      image = image.resize(display_size)
      render_to_screen(image)

Subject: [Image-SIG] Second Derivative Test
Message-ID: <BAY111-F29F31BB076F4E274D4EA9BE18F0@phx.gbl>

Hi

I'm trying to do a second derivative test to an image for the purpose of 
finding extrema. I just want to make sure whether these are true or not:

Dxx = D(x+1,y) + D(x-1,y) - 2D(x,y)
Dyy = D(x,y+1) + D(x,y-1) - 2D(x,y)
Dxy = D(x+1,y+1) + D(x+1,y-1) + D(x-1,y-1) + D(x-1,y+1) - 4D(x,y)

Secondly, I'm trying to store all the extrema detected in a Nx2 array where 
N is the number of extrema, and 2 being the x and y coordinates of them. 
Since I don't know how many extrema will be detected, can we create an empty 
array in python without specifying the size, and later append the data to 
that array

Thanks a lot

looks reasonable.

any reason you cannot use a Python list for this ?

Subject: [Image-SIG] Image.putdata, Python crash
Message-ID: <4491D21C.8010408@gmail.com>

Hi,

Because of my lousy code/PIL newbieness or something completely 
different, Windows Python 2.4.3 crashes (in _imaging.pyd) after a call 
to  Image.putdata(a_list_of_ints).
Python gives no errors messages.

The image, a BMP file is written by PIL itself. I have thousands of 
them. I've tested several of them of them with same result.
Saving a copy of the file from Paint.exe etc. does not change anything.

The files are created by saving only the R band after Image.split(). 
They contain only two colours, 0 and 255.

The file(s) _does not_ verify. Image.verify() gives AttributeError, but 
Image.load() and .show() and all other methods works.

Simplyfied repro code below. UUE of the insulting BMP file included 
below. I'll happily send a copy of the BMP.

I get "Warning: Trailing garbage" and a truncated BMP file, so an

after some digging, this appears to be a bug in how putdata behaves on 
memory-mapped images.  the simplest way to work around this is to do:

     img = Image.open(bmp_file)

     img = img.copy() # make sure we have a writable copy

if you want to be a bit more careful, you can do:

     # make sure putdata can write to the image memory
     img.load()
     if img.readonly:
         img = img.copy()

     img.putdata(...)

hope this helps!

there's an example in the Scripts directory in the PIL source distribution. look
for a module/script called "gifmaker.py".

Subject: [Image-SIG] Python crashes on FreeType bindings -- replicable
Message-ID: <4493B976.4060705@twardoch.com>


I'm getting many crashes when using the FreeType bindings in PIL with 
Python on Windows XP.

The crashes are consistant, on certain glyphs in certain fonts. At 
http://www.twardoch.com/tmp/crashPilFont.zip there is a small archive 
that contains a Python script, the binary libraries, some fonts of which 
one causes a crash (the italic), and an out.txt file that shows the 
output of the script (showing when it crashed).

I'm always getting the same crash:

AppName: python.exe     AppVer: 0.0.0.0     ModName: ntdll.dll
ModVer: 5.1.2600.2180     Offset: 00010f29

I tried this on two different Windows XP machines (one having a normal 
clean install of Windows, Python and PIL, the other being a developer's 
machine with many different things installed). I've tried Python 2.4.3 
with PIL 1.1.5, I've tried Python 2.5a2 with the pre-built PIL 1.1.6a0. 
I even tried the _imaging and _imagingft copies from Reportlab 
(http://www.reportlab.org/ftp/win32-dlls/2.4/). All the same.

But many other fonts work just fine.

In my code, I'm calling _imaging and _imagingft directly. That's just to 
nail the problem down. I've used the "official" way over PIL.Image and 
PIL.ImageFont, it's all the same.

It appears that the crash occurs at the line
im = _imaging.fill(self.mode, self.size, 0)
which is quite strange.

Do you know why this may be happening?

this is a bug in PIL's font rendering code; see

Thanks for support.

I did it this way:

sequence = []

for s in range(steps):

            im = scipy.misc.toimage(arr, cmin=0, cmax=255, high = 255, low = 0, pal=colorMap(), mode='P')

            im = im.transpose(Image.FLIP_TOP_BOTTOM)

            sequence.append(im)

fp = open(sys.argv[4], "wb")

gifmaker.makedelta(fp, sequence)

fp.close()

Hi all,

I'm trying to compose a image with transparency in
mode RGBA. But first I changed some pixels values by
retrieving the palette with getpalette(). 
Things were doing ok until I decoupled a function
similar to getcolor() that inherits somewhat from
ImagePalette...

Now I get a 'IndexError: tuple index out of range'
error whenever I'm trying to mix-up palette entries 
and filtering a (converted) RGBA single-color band. :/

Is their something I missed about using ImagePalette
instances with Image.putpalette() ?

Thanks,

Etienne

PS, This is PIL version 1.1.5

Subject: [Image-SIG] ImageTk and threading - warning
Message-ID: <059f01c693df$60d527d0$650aa8c0@duallie>

I'm not sure how many people out there are doing multi-threading and Tk, but 
I just wanted to post a warning after spending a few months trying to track 
down a nasty (and very rare) crashing bug in one of my programs.  I wish I 
had been more skeptical from the start.  :)

I know that Tkinter isn't thread safe - so only use one thread to touch any 
Tkinter objects or their properties.  However, I didn't think twice about 
creating an ImageTk.PhotoImage(of_my_image) in a secondary thread, and 
passing it to the GUI thread for display.  For some reason, doing this works 
in 99.99% of the time, but occasionally crashes with an access violation 
error, pointing to the Tk DLL.

So - until Tk is thread-safe (I'm not holding my breath, it wouldn't be a 
trivial task), just use the same thread that creates the Tk widgets to 
convert your images to PhotoImages.

Message-ID: <10bebef56be.andrea_gavana@tin.it>

Hello NG,

    I am using PIL to load and display some pictures (via 
wxPython) in a GUI. I have added the ability for the user to change the 
linear dimensions of the image (in pixels) and the quality of the image 
in order for the image to be saved in another file. I was wondering if 
is there a way to know in advance, based on the pixel dimensions 
specified by the user and by the image quality, which file size (in 
bytes) I will obtain for the new image (approximatively). Is there a 
way to obtain such result without actually saving the image?

Thanks 
for any hint.

Message-ID: <e7b03r$9l9$1@sea.gmane.org>

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

    http://effbot.org/downloads/#Imaging (source)
    http://effbot.org/downloads/#PIL (windows binaries)

Changes from 1.1.5 include:

- new ImageQt module provides image support for PyQt4
- numerous improvements to the TrueType rendering, including proper
  (and crash-free) handling of fonts with negative bearings, and support
  for kerning.
- new ImageMath module for applying arbitrary expressions to images
- faster pixel access via separate "access" objects

As usual, PIL 1.1.6 supports all Python versions from 1.5.2 and onwards,
including the upcoming 2.5 beta.

For a more complete list of changes, see:

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

Report bugs to this list as usual.  (bugs in the alpha/beta releases can
also be reported directly to me, if you prefer)

if we're talking about formats like JPEG and PNG, the compression ratio
depends on the image content, so the short answer is "no", and the some-
what longer answer is "it depends".

if you want *very* rough estimates, you can use something like:

    def getroughsize(im, format):
        pixels = im.size[0] * im.size[1]
        if im.mode == "RGB":
            pixels *= 3
        if format == "PNG":
            return pixels / 1.5 # photographic content
        if format == "JPEG":
            if im.mode == "RGB":
                return bytes / 20
            return bytes / 10
        return bytes # assume uncompressed format

the scale factors used above is for typical photographic content; drawings
and other graphics can often be compressed a lot more, while very noisy
pictures result in lower compression ratios.  tweak as necessary.


to get an exact value, you have to compress the file.  the following snippet
uses a stub byte counter class where possible, and falls back on a full in-
memory compression (via StringIO) for encoders that need random access
to the file:

    import Image
    import cStringIO

    class Counter:
        bytes = 0
        def write(self, data):
            self.bytes += len(data)

    def getsize(im, format, **options):
        try:
            out = Counter()
            im.save(out, format, **options)
            return out.bytes
        except AttributeError:
            # fall back on full in-memory compression
            out = cStringIO.StringIO()
            im.save(out, format, **options)
            return len(out.getvalue())


a third approach would be a turn this into a statistics problem, and calculate
some global stats (such as RMS etc.) on the image, and compare that to the
achieved compression ratio for a reasonably large set of typical images.  I'm
sure someone has done this already, but I have no time for a literature search
today...

I'm installing Imaging-1.1.5 on rhel 4.3.   selftest.py fails bcs "decoder

zone.effbot.org page for "decoder jpeg not available" at

is to run ./configure in the libImaging directory. I don't have a configure

I have Imaging-1.1.5 running on a CentOS-4.3 box. There is no configure in 
libImaging/ there either.

I tried changing setup.py to point to the libjpeg directory but it still 
doesn't find the decoder.

What can I try?     python -vv -c "import _imaging" gives the following:

the big blurb at the top of that page that says "This applies to PIL 
1.1.4 and earlier." and goes on to explain what do for 1.1.5, perhaps ?

(do you have the jpeg library on your machine, btw?  you need both the 
library and the developer files; installing the "jpeg-devel" package is 
usually the easiest way to fix this.  with this in place, the setup 
script should take care of the rest, all my itself.)

(you could also look for python-imaging in your favourite redhat 
repository.  )

that should probably be "libjpeg-devel" for RHEL, though.

Hi everyone, I'm having some problems with basic PIL functions.  First, when
I try to call the size() method, I get a typeerror (tuple object is not
callable).  And similar errors for other methods.
Also, when I try to use getdata(), I get an error message that says
"ImagingCore object at <hex-address>".  However, some methods, like
getpixel(), do work.
I'm using the newest distro of Python and the newest binary build of PIL, on
Win2k.  The image I'm working with is a TIFF file: here is the output of
tiffinfo:

size is an attribute, not a method:

     http://effbot.org/imagingbook/image.htm#Image.size

> Also, when I try to use getdata(), I get an error message that says 
> "ImagingCore object at <hex-address>".

that's not an error message, that's the standard string representation 
of the sequence-like object returned by getdata().  as explained here:

     http://effbot.org/imagingbook/image.htm#Image.getdata

you can use list() to convert it to an ordinary list.  you can also 
iterate over it, or pass it to any function that expects a sequence 
object or iterator.

see your favourite python tutorial for more information on things like
attributes, sequences, iterators, exceptions and tracebacks, etc.

Hello Everybody,

First please forgive me for asking such a basic question but I am a newbie
to Python, to programming and I am alone with my IT worries.
I would like to access pixels values in order to make some computations but
with the 1.1.6 PIL, I don't understand.
As an example, here is what I do:

import Image
im = Image.open("myimage.jpg")
pixel=im.load()
print pixel [0,0] # to see the value of pixel[0,0]
x=(0,0,0) #black in RGB
pixel[0,0]=x # to set the first pixel in black

This gives me an error : "TypeError: unsubscriptable object".
I believe I am doing something wrong ;(

May someone just explain me with such an example what I should do.
Thanks in advance for your help

Dom,

You should consult the very good on-line documentation (search for
"python image library"). Here is a hint:

import Image
im = Image.open("myimage.jpg")
im.getpixel((0,0)) # position (0,0)
im.putpixel((0,0), (0,0,0) ) # black

are you sure you have PIL 1.1.6 ?  what does

     >>> import Image
     >>> Image.VERSION

print ?

Fredrick, Douglas, All,

I have Pil : Image.VERSION: '1.1.6a0-20051002'.

I  finally managed to have this useful pixel function work fine.
I don't understand why  it did not work before.
Maybe I was still in Python 2.4 and PIL 1.1.5  ??? (I have 2 python and 2 
PIL on my PC).
The important thing is that it now works.

Thank you Fredrick and also many thanks to Douglas S. Blank for your swift 
replies.

Dom

I've developed an application that uses PIL+aggdraw on the server side to

was able to resolve issues without extra help.

So anyway, I thought I'd just say thanks to all the people making PIL into
what it is!

If you're interested, you can check out http://mydrawings.com to see what
we've come up with.

A couple things I encountered in the process:
 1) w/ aggdraw, I didn't find a documented way to change the default line
ending and line caps so I changed the default in the source and recompiled.
I'm sure there was a way to do that but I never ran accross it.
 2) when I size images (using ANTIALIAS) smaller, the white space from the
original image is somewhat distorted and not completely white.

Anyway, these were small issues and overall, I'm quite happy with the way
PIL is working for me.

Thanks

Subject: [Image-SIG] Storing instance of a class in an array
Message-ID: <BAY111-F11FE69BDED11BC959C4177E17F0@phx.gbl>

Hi

Is there any way to store instances of a class in a 2-dimensional array? How 
do you declare the array? I was thinking something like this

a = ClassName(arg1, arg2,arg3)

so that a.arg1 = arg1, a.arg2 = arg2, a.arg3 = arg3

if I've got 9 of a, how do I store them in a 3x3 array

I tried to initialize the array as having a 0 value first by typing

array = zeros((3,3))

but when I assign array[0][0] = a, it just return an error of bad value type

If I can store those instances in an array, how do I initialize the array?

Thanks a lot

if "array" refers to Python list, this question should really have been sent to a general
python forum, and the answer is found here:

    http://pyfaq.infogami.com/how-do-i-create-a-multidimensional-list

if "array" refers to a Numpy array, you may have better luck by asking on a Numpy
support forum.

if "array" refers to a PIL image memory, the answer is "you cannot do that".

Subject: [Image-SIG] 16-bit ppm or psd support in PIL?
Message-ID: <44A417D2.6070501@klaff.org>

Hi,

I would like to play with some 16-bit ppm or psd files in PIL.  These 
files are created from digital camera raw files (Nikon .NEFs actually)  
using dcraw to create either .ppm or .psd format files, for example:

dcraw -3 DSC_1234.NEF
or
dcraw -4 DSC_1234.NEF

I'm using PIL 1.1.5 on Windows XP w/ Python 2.4.2.

PIL will open the ppm file, but the pixel values returned appear to be 
8-bit and im.show() gives a malformed image, so I think the plugin 
doesn't understand the 16-bit format.  The psd plugin doesn't seem to 
recognize the .psd version of the file.

Has anyone tried to do this?  If a plugin were written to handle one of 
the 16-bit formats can the rest of PIL work with 16-bit data or is this 
a deep difficult problem?

Thanks,

Dave

looks like a botched or incomplete install; the selftest script picks up 
the Python files for 1.1.6, but the _imaging.so module for 1.1.5.

(note that you cannot use a plain "build" followed by selftest; you need 
to either do a "build_ext -i", or do a full install).

(using 1.1.6b1 instead of 1.1.6a2 is also a good idea).

Yup, thats was definitly a botched installation. :-)
