Are there any examples of python scripts doing basic image editing like
resizing a directory of files, or adding some text to an image, online ?

I'd like to overlay a url(text only) onto some images.
Depending on the image background color, I would need to change the color
of the text.

Is this technique of adding text to a graphic image called, watermarking,
merging, or ??? in the graphics editing world?

thanks

Howdy,

I am interested in writing some routines to

Can I use PIL to write data to png files?

Any examples available?

you should probably ask this question in a Gramps forum; it's just one of
many applications using PIL, and we cannot really provide support for all
of them...

from the look of it, the gramps-user list is what you're looking for:

Message-ID: <cjrlq4$6as$1@sea.gmane.org>

PIL 1.1.5 beta 1 is now available from effbot.org:

    http://effbot.org/downloads#imaging

(look for Imaging-1.1.5b1.tar.gz.  if you're using Windows, get PIL-1.1.5b1
for your Python version)

Changes in this release includes

+ Added new Sane release (from Ralph Heinkel).  See the Sane/README
  and Sane/CHANGES files for more information.

+ Added experimental PngInfo chunk container to the PngImageFile
  module.  This can be used to add arbitrary chunks to a PNG file.
  Create a PngInfo instance, use "add" or "add_text" to add chunks,
  and pass the instance as the "pnginfo" option when saving the
  file.

+ Added "getpalette" method.  This returns the palette as a list,
  or None if the image has no palette.  To modify the palette, use
  "getpalette" to fetch the current palette, modify the list, and
  put it back using "putpalette".

+ Added optional flattening to the ImagePath "tolist" method.
  tolist() or tolist(0) returns a list of 2-tuples, as before.
  tolist(1) returns a flattened list instead.

+ Some more (minor) build tweaks.

For a list of other changes in 1.1.5, see this page:

    http://effbot.org/zone/pil-changes-115.htm

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

in 1.1.5b1, you can do:

    import PngImagePlugin
    info = PngImagePlugin.PngInfo()
    info.add_text("KEY", "VALUE") # adds tEXt chunk
    ...
    image.save("somefile.png", pnginfo=info)

you can get the latest beta here:

Message-ID: <11341.1096902769@www51.gmx.net>

Hi, everyone,

I'm currently trying to install PIL 1.1.4 on my vServer running SuSE 9.0.
The compilation of libImaging worked just fine, but "python setup.py build"
yields:

Traceback (most recent call last):
 File "setup.py", line 287, in ?
   extra_compile_args=EXTRA_COMPILE_ARGS,
NameError: name 'EXTRA_COMPILE_ARGS' is not defined

So, what would be the correct value for EXTRA_COMPILE_ARGS?

Python version:
Python 2.3.4 (#1, Aug  6 2004, 23:04:41)
[GCC 3.3.1 (SuSE Linux)] on linux2

Any ideas?

Thanks in advance,

Tobias

Ah, thanks. Somehow I overlooked this one.  Installation of v1.1.5b1
seems to have worked.

Subject: [Image-SIG] draw.text problem
Message-ID: <20041007123000.GA5352@aku>

Hello.

My problem is that draw.text() seems to cut the lowest row of
a font. You can see that with the chars "gjQ{}[]" for example.
I tried several TrueType fonts with the same result.

There is a small test script attached, which shows the problem.
You can look at its output here:
http://hcoop.net/~aku/pil/text.png

And here is an image which shows how "gjQ{}[]" should look like:
http://hcoop.net/~aku/pil/text_ref.png

I made this also with pil a while ago. But i don't know what changed
since then. Do you get the same output with the script? Thanks in
advance for any help.

Regards

Message-ID: <49F73BEED865D3119F8700902773C9F904773403@exchange09.rl.ac.uk>

Dear All,

I am trying to build PIL 1.1.4 on a RedHat Enterprise AS 3 Update 3 box,
but it fails at the process:

   python setup.py build

in that it complains:

_imagingtk.c:20:16: tk.h: No such file or directory

and then crashed out. 
There were no errors reported when I followed the installation README file
until this step.

I have attached an extract of the error here.

I then tried to copy a tk.h file from a RedHat 9 system, and repeated the
build process.
It gives more tk.h syntax errors unfortunately.

Anyone has got any idea how to fix this?

By the way, the system has the following installed:

freetype-2.1.4-4.0
gnome-python2-1.99.14-5
gnome-python2-bonobo-1.99.14-5
gnome-python2-canvas-1.99.14-5
gnome-python2-gtkhtml2-1.99.14-5
libjpeg-6b-30
libxml2-python-2.5.10-6

MySQL-python-0.9.1-6
python-2.2.3-5
python-devel-2.2.3-5
python-optik-1.4.1-2
rh-postgresql-python-7.3.6-7
rpm-python-4.2.3-10
zlib-1.1.4-8.1
zlib-devel-1.1.4-8.1

I have noticed that most of the libraries are residine under /usr/lib
rather than /usr/local/lib as expected in Setup.

Thank you.

I have later found out tk.h comes in tk-devel kit.

I have loaded the rpm onto the RedHat AS 3U3 box,
cleaned up the whole Extensions tree, and started from fresh.

This time, I still hit a problem on python setup.py build.

It complains: 

_imagingtk.c:23: syntax error before '*' token

and finaly
erro: command `gcc` failed with exit status 1

So I would appreciate some help in mounting PIL 1.1.4
on RedHat Enterprise 3U3.

Dear all,

I dropped a few postings last night regarding the building on PIL 1.1.4
on a RedHat Enterprise AS 3 U3 system.

(I have not seen any of my posts back though since the posting last night).

This is just a quick note to say that I have managed to work out 
where the problem was, and get the sources to compile.

Apparently under RH Enterprise, the header files for tcl and tk are no
longer
bundled with their kits, but placed under the development RPM.  They in
turn require quite a bit of dependent packages to be loaded.  But once done,

the python build script works ok.  I can get our users to try out the newly
built PIL.

have you updated PIL and/or the freetype2 libraries?

I get better results on my machine (using verdanab.ttf from Windows XP
and freetype 2.1.8), but I can see similar problems at some font sizes.

freetype isn't exactly the most stable and well-documented API you can
find, so I'm probably using and old API which they have broken since then.

I'll take a look when I find the time (patches are welcome, if some freetype
expert has more time to spare than I have...)

This reminds me of a question that I've been meaning to ask:

Have you considered using Antigrain Graphics as the drawing engine for 
PIL? It produces very nice anti-aliased graphics and text. There have 
been numerous discussions on various mailing lists about how nice it 
would be to have a general purpose Python wrapper for AGG. It's being 
used in SciPy/Chaco and matplotlib, but they've only wrapped up the 
specific functionality that they need. Maybe PIL would be a good place 
to put it.

Don't know if it helps, but i'm using the latest
versions of freetype and PIL currently available
in gentoo linux, which are

  dev-python/imaging-1.1.4
  media-libs/freetype-2.1.5-r1
  > freetype-config --version
  9.4.3

I also unmasked and installed freetype 2.1.7 and
2.1.9, but then PIL doesn't compile (which is
why they are masked obviously). Also earlier
versions of PIL do not compile against freetype
2.1.5.

Hi,

what do you expect that line to do?

there's no tostring packer defined for RGBA->RGBX.  if you want to
store the pixels as 32-bit entities, just store them as is (RGBA instead
of RGBX).  if you want to get rid of the alpha, convert to RGB before
storing as RGBX.

In the hope that a later freetype version solves the problem,
i installed freetype-2.1.9 into my home dir. Now how can i
configure PIL to use this freetype version instead of the one
installed under /usr ? I looked at ./configure --help and
the docs but didn't find information on it.

Hi all,

I am trying to draw a cropped image from a larger image smoothly every 
frame. Essentially there is no problem to crop a image (image.crop) 
every frame even at 140Hz (about 7ms). But, when the cropping size 
exceeds 512x512, the cropping performance suddenly drops to 50ms or 
more. This situation was confirmed under Windows2000 and Mac OSX 10.3. 
Is this a PIL problem or a hardware problem (such as a video card or 
AGP bus speed) ?

Anyone has any idea?

Thanks in advance,

Dear all,

I hope someone might be able to help with what might be a *very* simple
question.

We have some clinical images (normally a sequence of 3) that we are
trying to 'align'. We would hope that these grey scale images (256 by
256) are identical and we are trying to come up with a way of
quantifying the 'agreement'. We have been simply using the mean standard
deviation of the pixel heights (MSDPH). Could someone provide me with a
reference for alternative similarity metrics? In particular some images
have more features (edges) than others, so my intuition tells me we need
to correct for this in out metric, hence the unsuitability of MSDPH).

Thanks for your patience!

are we talking about color images?

if so, you're actually hitting a limit in PIL: the internal storage module
switches allocation strategy for images that need more than 1 mega-
byte of storage.  It's unlikely that the alternate storage strategy can
explain a 7x performance drop, but one never knows...

to see if this is the problem, you have to edit the libImaging/Storage.c
file.  change

#define THRESHOLD 1048576L

to, say,

#define THRESHOLD 4*1048576L


and rebuild.

(I should probably increase the threshold in 1.1.5 final; PIL's almost
10 years old, so parameters like this could need some tuning...)

Why not make it a variable, and add a function to allow it to be
dynamically set?  It's only used in that one call.

Subject: [Image-SIG] Speeding up image.resize()
Message-ID: <20041018235643.GA26950@unpythonic.net>

After seeing how slow image.resize() is, especially ANTIALIAS, I looked
at the underlying code in libImaging.

I examined the object code produced for Antialias.c.  On my system
(linux on intel) not only is there a function call for XXX_filter, but
antialias_filter has more function calls inside as well (including a
call to libm's sin())

To improve the speed, I made all the XXX_filter functions (including
sinc_filter) 'static inline', and moved most of the body of
ImagingStretch into an include file, which is included once for each
filter.  ImagingStretch now dispatches to one of the 4 _XXX_filter
functions, instead of merely setting some function pointers.

I also set some extra_compile_args appropriate for my system and
compiler:
    exts = [(Extension(
        "_imaging", files, libraries=libs, define_macros=defs,
        extra_compile_args=['-O3', '-march=pentium4', '-mfpmath=sse',
                            '-msse2', '-ffast-math', '-mno-ieee-fp']
        ))]

In their current form, I doubt these changes are suitable for inclusion
in Imaging (because of the use of the "inline" extension and specialized gcc
compiler flags).  However, I thought this might be helpful to someone.
If there's interest, I can produce a patch.

How much difference?  I used 'timeit' on Imaging-1.1.5b1 and my modified
version of it.  I tested on a laptop with a 1.5GHz Pentium-M CPU, with
SpeedStep disabled.

The script:
    import Image
    i=Image.open('test.jpg')
    i.thumbnail((1024,768), Image.ANTIALIAS)
    i.load()
test.jpg is a 3072x2048 digital camera image, which (I assume) is
loaded as 1532x1024 and resized to 1024x682.

1.1.5b1 gives:
    10 loops, best of 3: 1.24e+06 usec per loop  (1240 msec)

My version gives:
    10 loops, best of 3: 6.99e+05 usec per loop  (699 msec)
That's a 43% speedup.

Here's data for all filters:
            (times in msec)
Filter      Vanilla     Patched     Speedup
ANTIALIAS   1240        699         43%
BICUBIC     783         626         20%
BILINEAR    576         439         23%
NEAREST     411         517         -26%  (!)

Atteched here a function that generates a quadratic distortion mesh for an image. Its doc string docuiments how to use it.

The Image.trasform->MESH method uses repetitive  calls to Image.transform->QUAD method. Thus, as documented,  MESH data, is just a list of QUAD data. You should pay attention to to following:
 1. There is a spedific order of the rectangle and the quadrilateral vertices.
 2. Two adjacent quadrilaterals in the mesh have a common edge. You should provide this edge twice --- once for each quadrilateral.

I hope that the attached function would help to clarify.

  Nadav.

Thanks for your reply. I tried and tried to rebuild the library as 
suggested, but unfortunately I could not. It is hard, since I am 
unfamiliar with compiling C especially in Windows, and I do not have 
the MS Visual C compiler.

So could you anyone send me the customized version of PIL ?

Subject: [Image-SIG] Applying a palette to an image
Message-ID: <3d0cebfb041022112343638524@mail.gmail.com>

Hi,

Is there a way to apply a custom palette to an RGB-mode image using
PIL? I've looked at .putpalette and .convert and it seems there is
only support for either converting to the special web-safe palette or
generating a new palette based on the colors in the image.

I am writing a game editing application that is able to load images
from conventional files and convert them into a specialized format,
mapping colors to the game's pre-defined palette. Going from file to
raw bytes via PIL, and then through a routine that shuffles pixels
around to the specialized format, is fast enough even though the last
step is coded in Python. However, matching colors from a palette with
Python when starting from a 24-bit image is a serious bottleneck.

If there is any way this can be done with PIL that I've missed (I
wouldn't be surprised), information would be much appreciated. In case
there isn't, I might have to put the palette lookup code in a C
extension, which would be somewhat inconvenient. In that case, I'd
also take the opportunity to request humbly that this feature be
included in future versions of PIL.

Thanks,
Fredrik Johansson

Can anyone tell me how to set the resolution unit when saving a tiff?  I 
set the dpi but it is unitless so doesn't register the dpi properly.  I 
am using the 1.5 alpha release as I couldn't set dpi at all prior to 1.5.

I set the dpi like so:
orig.save('/tmp/orig.tif',dpi=(300,300))
but haven't figured out how to get the unit correct.

Here is the original files info:
TIFF Directory at offset 0x8
  Subfile Type: (0 = 0x0)
  Image Width: 1359 Image Length: 1355
  *Resolution: 300, 300 pixels/inch*
  Bits/Sample: 8
  Compression Scheme: None
  Photometric Interpretation: min-is-black
  Samples/Pixel: 1
  Rows/Strip: 753
  Planar Configuration: single image plane

and the saved one:
TIFF Directory at offset 0x8
  Image Width: 1359 Image Length: 1355
*  Resolution: 300, 300 (unitless)*
  Bits/Sample: 8
  Compression Scheme: None
  Photometric Interpretation: min-is-black
  Rows/Strip: 1355
  Planar Configuration: single image plane

Subject: [Image-SIG] Questions about a 16bpp TIFF
Message-ID: <GKEBLAIAHOIHHOJGAOKJKEBLCEAA.dvarrazzo@virgilio.it>

Hi everybody,

i am trying to use PIL for a 2d electrophoresis gel images database. Those
images are TIFFs obtained from a densitometer, so lower values are
interpreted as white. The precision is 16bpp. This combination yelds a key
(0, 1, (16,), ()) for OPEN_INFO, but there is not such entry, so the opening
fails.

Can those images be opened through PIL by simply adding a new key to
OPEN_INFO or the workaround is more complex? What values?

By now i tried duplicating the values for (1, 1, (16,), ()) and inverting
the image.

I need to convert the image into something suitable for the web, i.e.
downsize it and store into an 8 bit jpeg. It looks like Image.convert('L')
simply crops what's more than 255, so i should multiply each pixel for 1/256
before converting. How can i do it? The only way looks like
	ImageChops.add(img, ImageChops.constant(img, 0), 1.0/256)
but it can't be like that! Both because creating and adding zeros looks like
a waste of time and because it doesn't work for 16bpp images. How can i
convert a 16bpp grayscale image into an 8bpp without a level rescale instead
of a cropping?

Some hardware return a 12 bpp image, so only 8192 from 65536 gray levels are
actually used. Thus the multiplying factor should take into account the max
gray level. But getextrema returns None, even if the manual states it works
for single plane images. Is it a bug "or a feature"?

Is PIL the right package for my needs? Is there any easy way to obtain a
numeric or numarray matrix from the image to freely work over it?

To get a copy of the image i am talking about, you can download and install
the demo version of the ImageMaster program at
http://promo.amershambiosciences.com/INTL/imagemaster_demo/
and play with the file C:\Program Files\Amersham Biosciences\ImageMaster 2D
Platinum Trial\Gels\ECOLI.mel (it is a TIFF image with some extra tags) or
ask me for some image (if you don't want to download the 12MB package).

Any help would be appreciated. Thank you in advance.

 Hi,

 I'm trying to generate a Transparent PNG image, supported
 by both Mozilla and IE6.0. The code below gets the job done for
 Mozilla, but fails for IE. 

 When I generate indexed PNG images, I get a black background instead
 of a transparent one.

 Moreover, I saw references in the mailing list to the
 .info['transparency'], but I do not know how to used it
 or even if this is still supported ?

 I would appreciate any hint or documentation pointers on the subject.

 best regards,
 Senra

Subject: [Image-SIG] a bug in PIL?
Message-ID: <20041028145244.GB29451@students.cc.tut.fi>

Hi! I tried to install PIL, but it gave some errors. I asked about
these errors in Python tutor-mailing list and they said to ask
here. So, here I am now. :) If you need some additional info, just
ask. Some guy said "After a quick look at setup.py I think this is a
bug. EXTRA_COMPILE_ARGS is only defined if Tkinter is present but it
is used outside the test for Tkinter." So, is this a bug or only an
(un)documented feature? ;)

Oh, I don't have root-account in that machine (it's in my school) so
is it possible to install/use PIL there?

Thanks for the input, but it doesn't, unfortunately, help - I have those 
files too. I presume you are using PIL 1.1.4?

I thought it might be a 1.1.5b1-specific thing, but sadly a de-install 
followed by a re-install of 1.1.4 gives me the same error - a dialog box 
appears telling me that libjpeg.dll can't be found in any of an umber of 
directories (not surprising, since there is no such file on my disk).

I thought I'd fixed the problem by copying jpeg62.dll from GTK 2.0 and 
renaming it as libjpeg.dll, but unfortunately Windows then started 
complaining about the absence of libz.dll (and a copy of libz.pyd 
definitely won;t do the trick).

So I'll copy this to the PIL support list and see what the gurus have to 
say. I'm wondering if there could possibly be any interaction between 
the Cygwin and Windows versions, since both are now loaded on the same 
machine. Bit stumped here ... I don't remember PIL being so 
temperamental before, and it's working beautifully under Cygwin.

It is a known bug.  You can find a patch on the PIL 1.1.4
errata page:
  http://effbot.org/zone/pil-errata-114.htm

I haven't tried it with PIL, but I would expect you can use the
--prefix=$HOME/lib switch for setup.py.  (And then adjust your
PYTHONPATH to include that directory.)

You might want to try PIL version 1.1.5 which is currently
being beta tested.  It has a new setup.py that streamlines the
build process.

Message-ID: <000001c4bf98$0ae8a710$fe78a8c0@claudia>

Dear Sir/Madam,
 
I've installed python 2.3.2 and installed
PIL-1.1.4.win32-py2.3.exe;which is the python image library module.
 
However, if I run the simple test program below:
 
import Image
im = Image.open("Images/lena.gif")
print im.format, im.size, im.mode
im.show()
 
It come up with this error:
 
ImportError: The _imaging C module is not installed
 
 
Also I checked the paths and it seems ok:
 
 
sys.path
['C:\\Python23\\Lib\\idlelib', 'C:\\WINDOWS\\System32\\python23.zip',
'C:\\Python23', 'C:\\Python23\\DLLs', 'C:\\Python23\\lib',
'C:\\Python23\\lib\\plat-win', 'C:\\Python23\\lib\\lib-tk',
'C:\\Python23\\lib\\site-packages',
'C:\\Python23\\lib\\site-packages\\PIL']
 
Also,  tried executing import _imaging and this is fine as well!!
 
Can you see if you could shed some light on this problem please
 
Best Regards
 
Chris Sidiropoulos
