Strange indeed. The same is true for UnsharpMask:

class UnsharpMask(Filter):
    name = "UnsharpMask"

    def __init__(self, radius=2, percent=150, threshold=3):
        self.radius = 2
        self.percent = percent
        self.threshold = threshold
    def filter(self, image):
        return image.unsharp_mask(self.radius, self.percent, self.threshold)

Subject: [Image-SIG] PIL 1.1.6 can't convert 16-bit (I;

Message-ID: <9cd318911002281950o30f201d1ieb86ea99c498097b@mail.gmail.com>

Greetings,

I'm reading in a 16-bit monochrome image using PIL on windows and can't seem
to work with the resulting image object.

I've confirmed the image data is good..I can open and view it with ImageJ
and the dimensions are correct.

I'm using PIL 1.1.6 as part of the Enthought Python distribution...I'm
stumped. I've appended relevant code I'm trying with my interpreter below:

I'm hoping perhaps someone can help...I need to take 16-bit monochrome
images (*.tiff in this case) and get them into 8-bit space...thanks in
advance for any insight into what I can do to solve this.

print im.mode,im.size
I;16 (832, 656)

print im.getextrema()
None # this doesn't seem right....can PIL 1.1.6 apply this method to 16-bit
unsigned int image objects?

lut=[]
len(lut)
0
for i in range (65536):
    lut.append(int(i/256))

len(lut)
65536

im3=im.point(lut,'L')

How I would convert the image is im.convert("L") I have had success
using this method for a variety of less common formats, and it handles
all the conversion for you.

PIL has very limited support for the I;16 and I;16L modes; it's
usually best to convert them to mode I (or F) and move on from there.
Try doing:

  im = im.convert("I")

before applying getextrema and point(lut, "L") to the image.

Subject: [Image-SIG] PIL PNG encoding performance
Message-ID: <83CEF932-7548-4BD9-91CA-1CB6F1078BE1@bogosoft.com>

Hi,

I found out that the default PNG(ZIP) encoding options do not offer  
the best performance and output sizes. At least for "vector" images  
like street maps.
I changed the options of deflateInit2 in ZipEncode.c and tested the  
performance of Z_FILTERED, Z_DEFAULT_STRATEGY, Z_HUFFMAN_ONLY and  
Z_RLE and I tested different compression levels for some of the  
strategies.

I found out that Z_RLE offers the best performance while offering good  
compression, at least for my test image.

I tested with timeit.
-----
t = timeit.Timer("img.save('/dev/null', 'png')",
	"import Image; img = Image.open('test.png')")
print name, min(t.repeat(3, 10)),
-----

Here are my raw results, together with the resulting file size.
default0 is the Z_DEFAULT_STRATEGY with compression level 0, etc.

default   0.785417079926 296276
default0  0.171308040619 974861
default1  0.356842041016 323340
default3  0.441128969193 310072
default5  0.562795162201 298403
default7  0.990942001343 295061
default9  7.42386984825  289238
huffman   0.482778072357 409161
huffman1  0.450232982635 409161
filtered  0.821682929993 307535
filtered1 0.360295057297 323340
rle       0.341444015503 307691

For comparison the same tests as JPEG with different quality levels.

jpeg 0.515193939209 181315
jpeg85 0.553126096725 243813
jpeg90 0.587316989899 305299
jpeg95 0.649972915649 431085
jpeg98 0.728760004044 602096
jpeg99 0.771711111069 718724

I really would like to have more options in Image.save to choose  
different compression levels/strategies. I would like to add that to  
PIL and have some questions on how to add that.

At the moment save for PNG accepts only the `optimize` option which  
enables the best/slowest compression level (9). I think it would be  
bad for backwards compatibility to use this option to set the actual  
compression level. What about compress_level and compress_type for the  
options? I would add constants for the types in Image.py.

Any opinions or suggestions on that? I would do a fork on bitbucket  
then and start hacking.

Regards,
Oliver

Ok, I just started :)
I added compress_level and compress_type as save options for png  
files. The default behaviour is identical to 1.1.7.

Anyone care to review? http://bitbucket.org/olt/pil-117/changeset/8d4661695edd/

I load the ZLIB constants (Z_RLE, etc) into the _imaging module and  
then into Image. I'm not sure if that's OK, or if I should create some  
new constant values.

I did not prefix the constants, but maybe it is time to start with it.  
BILINEAR, RLE, FLOYDSTEINBERG, ADAPTIVE, ... it's getting a bit  
confusing.

Oliver

Is this a prebuilt version or something you built yourself?  It might
be that the selftest picks a different PYD file than your stand-alone
script.  Adding "print Image.core" to your test script will tell you
what version the script is picking up; compare that to the "loaded
from" lines in the test output to see if you're using the same
version.

Thanks.  I'll take a look when I find the time (and borrow the code if
that's fine with you).

Well, they all have the "Image." prefix :)

Not sure somewhat specialized encoder-specific settings should live in
that namespace, though; might be better to put them in the codec
module itself.  I'll think of something.

Some issues related to this were fixed in 1.1.7, but there are
apparently a few more things that can go wrong.  Some of this is
caused by semi-weird font metrics in some truetype files; the internal
API relies on being able to determine a pixel-level bounding box
before rendering, and it's likely that we have to change that to make
this work for all cases & fonts.

Sure. Do whatever you want, these changesets are CC0.

Sounds like a bug.  What does the getextrema() method return for the same image?

getextrema() returns the correct values, seems like the problem is
just in the ImageStat code.

If I remember rightly, you need to add a link to python.exe to your PATH 
variable.

Try Start Icon -> Right click on "Computer"
and go to Advanced System Settings.

Then go to "Environment Variables" on the Advanced Tab.
Find "Path" in the list of system variables at the bottom and add a link 
to the python.exe file at the end.

Hope you find it.

32-bit or 64-bit Windows 7 (and Python)?  The PythonWare builds are all 32-bit.

PIL uses the standard Python binary installers, so you might want to
look for solutions in other Python forums as well.

And if nothing else helps, there's always this:

    http://effbot.org/zone/python-register.htm

(which may or may not do the right thing on Windows 7; haven't tested,
but I seem to remember that people have used it successfully on Vista)

At this time, at least -- I'm looking into ways to get 64-bit builds
into the normal workflow.  In the meantime, contributions are welcome
(that's true for Mac OS X builds too).

(does anyone here know what happened to that Python build farm they
were working on some time back, btw?)

64 bit Windows and Python, that might be the problem. I did try the
register python script, it seemed to think there was a python version
installed (there is), and therefore did not help. I will look around
for 64 bit builds or see what I can do.

Subject: [Image-SIG]  Desperate GUI Help Please!!
Message-ID: <27915646.post@talk.nabble.com>


Hello,

I need to make a GUI which has a fixed window size approx 390 (width) X 6020
(height)

It needs to have a fileMenu containing "File" "About" "Exit". In the "file"
menu it needs a menuItem called "new route".

When you click on "new route" it needs to display a new window with a
listBox.. When a user selects an item from the list box and clicks OK - it
should pass this value to the original window.

The difficulty here is that the main body of the GUI window, needs to
display an image BUT it needs to be an image that is able to be drawed on.

Below is my code for drawing on the image....... It is an EXAMPLE - but i
need it like this i.e. by importing the ImageDraw library.

# Do the proper imports for this script
from Tkinter import *
import os, sys
import Image
import ImageDraw
# Load the image
try:
im = Image.open("C:\Documents and Settings\Administrator\Desktop\mm.gif")
except:
print "Unable to load image"
exit(1)
# Get a drawing surface for the image
draw = ImageDraw.Draw(im)
# Draw the circle
#draw.ellipse((0,0)+im.size)
# Draw the line
#draw.line((0,0)+im.size)
# and show off the result
draw.line((0, 0) + (0,55), fill=000, width=22)
draw.text((50, 50), "hey")
im.show()

Below is my code for the list box example......

from Tkinter import *
class ListBoxTest :
def __init__(self) :
self.root = Tk()
self.list_box_1 = Listbox(self.root)
self.list_box_1.pack()
self.delete_button = Button(self.root, text="Delete",
command=self.DeleteSelection)
self.delete_button.pack()
def DeleteSelection(self) :
items = self.list_box_1.curselection()
pos = 0
for i in items :
idx = int(i) - pos
self.list_box_1.delete( idx,idx )
pos = pos + 1
def Show(self) :
for i in range(0, 10) :
s = "Item " + str(i)
self.list_box_1.insert( END,s )
self.root.mainloop()
lbt=ListBoxTest()
lbt.Show()


Below is my code for the Canvas and Window BUT the canvas does not hold an
image I have drew on........

from Tkinter import *

class AppUI(Frame):

def __init__(self, master=None):
Frame.__init__(self, master, relief=SUNKEN, bd=2)

self.menubar = Menu(self)

menu = Menu(self.menubar, tearoff=0)
self.menubar.add_cascade(label="File", menu=menu)
menu.add_command(label="New")

menu = Menu(self.menubar, tearoff=0)
self.menubar.add_cascade(label="Edit", menu=menu)
menu.add_command(label="Cut")
menu.add_command(label="Copy")
menu.add_command(label="Paste")

try:
self.master.config(menu=self.menubar)
except AttributeError:
# master is a toplevel window (Python 1.4/Tkinter 1.63)
self.master.tk.call(master, "config", "-menu", self.menubar)

canvas = Canvas(width = 300, height = 200, bg = 'white')
canvas.pack(expand = YES, fill = BOTH)

gif1 = PhotoImage(file = 'mm.gif')
canvas.create_image(50, 10, image = gif1, anchor = NW)
canvas.pack()

root = Tk()

app = AppUI(root)
app.pack()

root.mainloop()


---- Is there anyone here who can put these elements together and maybe make
this GUI for me? I'm really stuck and as you can see by the code examples I
have gave this a shot, but I don't know how to finish it off - If someone
can do this for me - it would be great as I can look at the code and learn.

The Tkinter toolkit comes with a canvas widget that's probably a
better choice for the drawing parts of your application.  Tkinter
itself is a bit outside the scope for this mailing list; you'll
probably have more luck on the tkinter-discuss list:

    http://mail.python.org/mailman/listinfo/tkinter-discuss

or in the main Python forum.

Subject: [Image-SIG] PIL Fonts
Message-ID: <4BA52BBD.10901@evclose.freeserve.co.uk>

I am running Python 2.6 and have just installed PIL 1.1.7 running on Win 
2000.

When I try to get a font object eg by
font = ImageFont.truetype("C:\WINNT\Fonts\arial.ttf", 15)
I get an exception
   File "C:\Python26\lib\site-packages\PIL\ImageFont.py", line 134, in 
__init__
     self.font = core.getfont(file, size, index, encoding)
IOError: cannot open resource.

Looking into Class FreeTypeFont I see that _imagingft service is 
required. This file is present in C:\Python26\Lib\site-packages\PIL.
Should this file be installed during the Python2.6 setup? What should I 
do to fix this problem? I had basically the same problem with PIL 1.1.6.

Python interprets the "\a" in your string as a control character:

>>> "C:\WINNT\Fonts\arial.ttf"
'C:\\WINNT\\Fonts\x07rial.ttf'

See

    http://docs.python.org/reference/lexical_analysis.html#string-literals

for a list of such escape codes.

To fix this, use forward slashes (they work on both Unix and Windows),
double the backslashes, or use "raw" strings.  Your favourite Python
tutorial should have more information on how to work with file names.

Message-ID: <52453.1269123190@parc.com>

I think I need a language lawyer.  I'm finding that PIL 1.1.7 can't
import EPS files output by Adobe Illustrator.  It chokes on the
following sequence of lines in the header:

%!PS-Adobe-3.0 EPSF-3.0
%%Creator: Adobe Illustrator(R) 8.0
%%AI8_CreatorVersion: 13.0.0

When I look at it with pdb, the problem seems to be the %AI5 and %AI3
lines -- they don't match the header line template, though I believe
they are valid Postscript comments:

!Image.open("/project/uplib/samples/postscript/badfoo.eps")
*** IOError: bad EPS header
(Pdb) l
201  	                    if k[:8] == "PS-Adobe":
202  	                        self.info[k[:8]] = k[9:]
203  	                    else:
204  	                        self.info[k] = ""
205  	                else:
206  ->	                    raise IOError, "bad EPS header"
207  	
208  	            s = fp.readline()
209  	
210  	            if s[:1] != "%":
211  	                break
(Pdb) p s
'%AI3_ColorUsage: Color'
(Pdb) field
<_sre.SRE_Pattern object at 0x4798a0>
(Pdb) field.match(s)
(Pdb) ^D

So, are Postscript comments allowed in the DSC headers?  That is, is
this a PIL bug or an Illustrator bug.

Haven't checked the DSC spec in ages, but given your observation, it'd
probably make sense to skip all non-DSC comments no matter what the
spec actually says.  Can you provide a patch (or a sample file)?

Yes, I agree.

Yes, I think so.

Hello, 

Is there an estimate on when will the PIL be released for 3.x? How do I participate in that effort if I want to help out.

Thanks
Clement

 twice if xv and display are installed
Message-ID: <1270025726.17078.2.camel@soho.example.org>

hello,
I was using the .show() function on an Image object, and I had the
surprise to see 2 windows poping-up on my screen. One is xv and the
other one is display.

There is a little bug in ImageShow.py because the Viewer.show() is a
procedure and does not return anything. 
Well, in fact, it returns None which is interpreted as False. Hence the
bug.

cheers

Subject: [Image-SIG] Image.open won't work after reload(Image)
Message-ID: <4BB37F1B.2080204@cs.toronto.edu>

Hi all,

I'm not sure if this is a known bug.  If I reload(Image), then opening 
the image will not work under Python 2.6 on Ubuntu 9.04.  Here is my 
console output:

 >>> import Image
 >>> im = 
Image.open('/w/197/visionData1/bahenHallway/peopleSeq3/frame1300.ppm')
 >>> import numpy as np
 >>> im2 = np.asarray(im);
 >>> im2[[1:10], [1:10]]
  File "<stdin>", line 1
    im2[[1:10], [1:10]]
          ^
SyntaxError: invalid syntax
 >>> im2[1:10][:, 1:10]
array([[[255, 239, 216],
        [255, 243, 219],
        [255, 246, 222],
        [255, 248, 223],
        [255, 251, 225],
        [255, 252, 226],
        [255, 253, 227],
        [255, 253, 226],
        [255, 250, 223]],
...ETC...

I have a rough 3.X port sitting in a local repo, waiting for some
spare cycles to do a bit of merging to get it up to par with the 1.1.7
release.  Once that's done, I'll post the repo somewhere so more
people can hammer on it.  Stay tuned.
