what os and verson are you using. show is pretty much for debugging

is it RGB or something else?

I am using Lucid - Ubuntu on an FX- Sony laptop which is ten years old but
works excellent. The pictures I have tried are both RGB and grayscale tif
images. Some of them do open up but not others and I am not sure what type
of tifs open and why do the other tifs do not. I will try im.mode.
I have listed the tiffinfo properties of one type of tif that I could not
open in the postings.
Thanks,
gujax

Coordinates passed to getpixel should be in a tuple, like this:

im.getpixel( (5, 7) )

Message-ID: <AANLkTi=3VTARk7g3wrHE4YvcA-FrdhFT2QyoVEdsE73r@mail.gmail.com>

Hello all,

I am unable to draw kannada compound characters ???? ,   ??, ?? etc


over an image using ImageDraw module's draw method. Below is my code,

 #-*- coding:utf8 -*-
import sys, codecs, string
import Image
import ImageDraw
import ImageFont

txt = '???? '
font = ImageFont.truetype('Malige-n.ttf',20)
im = Image.new("RGBA",(800,600),(100,155,100))
draw = ImageDraw.Draw(im)
draw.text( (0,100), unicode(txt, 'UTF-8'), font=font2)
del draw
im.save('font.png', "PNG")
im.show()


And attached output image file displays '????'  by splitting it, but what i
want is to display ????  as it is.
Please suggest me where i went wrong.


Thanks & Regards
Shilpa

Have you tried another font? Do all fonts do this or just this one?

I noticed that you said font=font2, but have not declared font2, it
should be font=font. Besides that I messed around a bit with your code
and can't get it to work, but I don't have fonts with the right
glyphs, so I just get boxes. I assume that this font renders correctly
elsewhere. If that is the case, there might be something lacking in
ImageFont's truetype impementation.

Subject: [Image-SIG] TrueType/OpenType rendering bug in PIL 1.1.7?
Message-ID: <AANLkTikmfd59395T0WVNDHQ-AQrVeJ=ont2ascOmnamQ@mail.gmail.com>

I ran the following code in Python 2.6.1 with PIL 1.1.7 on Mac OS X 10.6.4:

#!/usr/bin/python
from PIL import Image, ImageDraw, ImageFont

image = Image.new("RGB", (800, 600), (127, 127, 127))
drawer = ImageDraw.Draw(image)

fonts = ("Verdana Bold.ttf", "Verdana Bold Italic.ttf",
         "Arial Bold.ttf", "Arial Bold Italic.ttf",
         "AGaramondPro-Bold.otf", "AGaramondPro-BoldItalic.otf",
         "Zapfino.ttf")

x = 100
y = 20
for name in fonts:
    font = ImageFont.truetype("/Library/Fonts/" + name, 32)
    text = "fish & chips (%s)" % (name)
    (w, h) = font.getsize(text)
    drawer.rectangle([x, y, x + w, y + h], fill=(0, 170, 0))
    drawer.text((x, y), text, font=font, fill=(255, 255, 255))
    y += h + 20

image.save("fontbug.png", "PNG")

The result can be found here:
http://files.looplabel.net/pil/fontbug.png

As you can see, the last two fonts are rendered outside the expected
box (as returned by ImageFont.getsize()).

It's also odd how the ending first 'f' of the Garamond Bold Italic
rendering is clipped to the left (compared to the second 'f' in the
sentence), as is the ending parenthesis of the Arial Bold Italic
rendering (clipped on the right, seemingly on the edge of the box
calculated by ImageFont.getsize()).

I am not sure which version of FreeType2 PIL is compiled against (PIL
was compiled from source), but it's the version installed in
/usr/X11/lib and /usr/X11/include on my system (i.e. whatever came
with Mac OS X, I haven't installed any custom versions).

I may be wrong, but as a naive user, I would expect ImageDraw.text()
to draw inside the same area as returned by ImageFont.getsize(). I've
also tried substituting ImageFont.getsize() for ImageDraw.textsize(),
but the results are the same.

So anyone have any clue on what's causing this and/or how to fix it?

... or maybe I'm just using the functions the wrong way?

BTW: I get the same (unexpected) result when running on a Windows
XP/Cygwin system (same versions of Python and PIL), compiled against
whatever is the latest version of FreeType2 for Cygwin -- I can check
when I access the Windows machine tomorrow.

Anders

I ran you code on my machine (win 7 Python 2.6.4, PIL 1.1.6) and after
changing the font names (they are different on my system) I got
similar problems, but not the same. I did notice that your image has
"fish & fhips" whereas mine says "fish & chips" Something seems to be
slightly off.
Hope that helps.

Not much help, I fear, but I tried it on my system and I don't have the

I created a binary installer for PIL 1.1.7 that is built against 
freetype 2.3.12 (which I believe is the latest) here:
<http://www.astro.washington.edu/users/rowen/python/>
but I used all the default build options for freetype; it has a lot of 
options to configure the build and you may wish to look into them.

Sorry about that. I changed the 'c' to an 'f' in the last minute
before I rendered the image to illustrate the cut-off of the first 'f'
(the second 'f' is for comparison). I forgot to update the source code
in the e-mail...

I see. I tried installing FreeType2 via fink, but couldn't get it to
work. Fink says the install was successful, but I can't find the files
in /sw/lib or /sw/include (and neither can PIL's setup.py). I think a
useful first step would be to find out if the issue is caused by
FreeType2 or PIL, so building FreeType2 from source and tweaking some
options might help with that.

I have also noticed a similar problem when drawing italic or "skewed"
fonts in PhotoShop. When I select the text for editing, the text
renders outside the selection box, just like in my PIL example, so
maybe this is a known issue with TrueType/OpenType fonts?

I'm not sure if the odd rendering affects centering in PS or if it's
just a visual quirk when editing, but in my code it's causing problems
because I want to use the width returned from getsize() to center the
text.

Subject: [Image-SIG] PIL Image array interface has the wrong size for YCbCr
Message-ID: <1286513509.2785.71.camel@krikkit>

PIL's Image class has incorrect dimension specified for YCbCr images.
This causes issues when converting to or from NumPy arrays.

According to http://www.pythonware.com/library/pil/handbook/concepts.htm
YCbCr should be "3x8-bit pixels, colour video format". Instead it
appears to be converted to a 4x8-bit format.

The incorrect definition is at line 206 of
http://svn.effbot.python-hosting.com/pil/PIL/Image.py.

Example: Load up any image and convert to YCbCr.

>>> import numpy
>>> import Image as im
>>> image = im.open('bush640x360.png')
>>> ycbcr = image.convert('YCbCr')

Using the Array interface produces a HxWx4 array, which is the wrong
dimensions for YCbCr. Thus when selecting a single channel it displays
incorrectly:

>>> A = numpy.asarray(ycbcr)
>>> print A.shape
(360, 640, 4)
>>> im.fromarray(A[:,:,0], "L").show()

Here's an example decoding the image byte string ourselves gives the
correct result:

>>> B = numpy.ndarray((image.size[1], image.size[0], 3), 'u1',
ycbcr.tostring())
>>> print B.shape
(360, 640, 3)
>>> im.fromarray(B[:,:,0], "L").show()

Attached is a patch against the 1.1.7-2 (python-imaging) package in
Ubuntu as I can't find the development repository for 1.1.7. See
https://bugs.edge.launchpad.net/ubuntu/+source/python-imaging/+bug/656666 for details.

Cheers,
David

Subject: [Image-SIG] Read SVG files - extracting the path
Message-ID: <32268588.1286557192780.JavaMail.root@viefep18>

Hi everybody!

I'm new to Python as well as to this mailing list and this is my question:

Is it possible to read a path provided by an SVG file, and based on that path, make a selection of an image?
(Further I'd like to invert the selection and fill it with black.)

Is that doable with PIL?

AFAIK ImagePath can create a path object, but is there a function, a module, or anything else that reads the path of the SVG directly?
I rawly could imagine to read the SVG as a text file, scan it for the "path" argument, read the subsequent tuples and make them a path object.

The plan B I'm working on is to do it with GIMP, which is a bit tricky because GIMP procedures are only accessible via the gimp-python console as far as I have experienced.

The hard facts:
Python 2.6.5 with IDLE
PIL 1.1.7
on Win XP 

Any hints are welcome.
Sebastian

Subject: [Image-SIG] Bug: ImageFilter.py GaussianBlur radius not set
Message-ID: <AANLkTimo=8nvajX_bpRQTuhwMoFZ6MAfVnDFdyzyat=U@mail.gmail.com>

The constructor for GaussianBlur class accepts the argument radius, with
default value 2,
but it does nothing with this argument, and instead hardcodes the radius to
2.

Below is the code found in PIL 1.1.7:
class GaussianBlur(Filter):
    name = "GaussianBlur"
    def __init__(self, radius=2):
        self.radius = 2
    def filter(self, image):
        return image.gaussian_blur(self.radius)


I believe it should be "self.radius = radius" instead.

#After that we create a class including some functions (defined by def) 

class MyClass(xbmcgui.Window):

  print 'hello world'

#So after that we initialize the class object and doModal() allows to always

Message-ID: <AANLkTikp0sJSB5vtC2KgeJoRCGq3dAwhSvjhoeCXLX9=@mail.gmail.com>

textsize for the same font and text gives different results on windows and

im = Image.new("1", (1,1))
draw = ImageDraw.Draw(im)
draw.setfont(font)

on linux (ubuntu 10.04) : 69

(the komika font can be get at
http://www.fonts4free.net/komika-text-font.html, same result can be achieved
with stock windows arial font)

Is there a way to be sure to have the same result on both platforms ? I
guess this has something to do with freetype and I could recompile linux
version with the exact same version used for the windows build, but how
could I know this version ?

Save it as a plain text file and give it a .py extension.
Open a command line and run it with:
python yourapp.py

No idea. What's this got to do with PIL?

according to PNG Specification, png8 images(with type 3) should support semi transparent images, with tRNS chunk, but current version of PIL does not handle it correctly

two simple patch can make PIL read this type of file correctly.

I've attached the patch file.

more efforts are needed to support saving png of this type.

PS: is there a bug tracing system for PIL?

Message-ID: <rowen-912F47.13411020102010@news.gmane.org>

I have made two Mac binary installers available for PIL 1.1.7:
one for Python 2.6 and one for 32-bit Python 2.7. Both require the 
python.org python and both are compatible with Mac OS X 10.3.9 and later.

Right now they are served here:
<http://www.astro.washington.edu/users/rowen/python/>
but that is only intended for temporary use. I would prefer they were 
served at the official PIL site.

Any hope of that, Fredrik?

For several years there was a central repository for Mac binary 
installers of python packages, and you could get Mac binaries for PIL 
from that. But that fell into disuse. Now I don't know of any sensible 
alternative for PIL.

I use it for some time with Py 2.5 and Py 2.6 on Windows, haven't moved 
to Py 2.7 yet.  Do not recall any problems when using it in relation to 
py2exe.

I use the "zipfile" option in py2exe, so the additional size is about 
500kb un-compressed with my usage(i.e. what I see in in zipfile/pil, see 
below for the "import's" I use).  Looking at PIL in site-packages this 
could go up to about 1.6 Mb.

In the setup.py I don't do anything special but in my code using PIL I 
have the following lines:

import PIL.Image as Image
import PIL.PngImagePlugin
import PIL.GifImagePlugin
import PIL.JpegImagePlugin
import PIL.BmpImagePlugin
Image._initialized=2

Subject: [Image-SIG] DPX decoder support
Message-ID: <4CC6E705.5050208@primefocusworld.com>

Hi there,

I'd like to write a DPX decoder for the PIL library.  I'm looking at the 
"Writing Your Own File Decoder" section, and I've written an image 
plugin which happily reads in all the necessary header data in the _open 
function.  The DPXs I'm currently working with have 10bit unsigned RGB 
channels (although the DPX spec allows for a lot of flexibility).  I'm 
looking at the 'bit' decoder provided, but it' doesn't appear to have 
the flexibility to specify that each 32bit element of the DPX data would 
be read as 3 unsigned 10bit RGB channels.  The docs indicate a parameter 
for the number of bits per pixel, and padding per line, but I'm not 
seeing how this would allow for the spec mentioned above.  This of 
course doesn't account for the log to lin conversion typicaly applied, 
either.  Also, looking at decode.c, the BIT decoder appears to only 
support "F" image mode.  Are there additional python functions in this 
framework that I can implement in order to support such flexibility in 
reading the 10 bits per channel data?  Or am I going to have to 
implement appropriate c code?

Thanks,

-mike

I build it on Windows and distribute it as part of a Windows MSI
installer (built using Python's msilib), not via py2exe.  No problems.
It takes about 2MB uncompressed, built with PNG and TIFF and JPEG
support.

extracting text from images falls into the optical character

that feature, try looking for specialized OCR libraries.

Subject: [Image-SIG] Reading a 8bit Tif image from ArcMAP doesnt read well
Message-ID: <AANLkTikYvHcXLNzCbnM7LwDAv2hYcbihU5P2JM-D3bh=@mail.gmail.com>

Good morning

Im reading an 8bit image generated by ArcMap using PIL in windows, the
image load well without error messages but, when I try to extract the
values to a numpy array I got some lines of the image with value of
pixel 127 (greyscale) or rgb(0,0,0). When I open the image using GIMP
or arcmap  I could see that the image is complete.

Any idea of what is happening??

the code that I'm using for read the image is:

     from PIL import Image
     from PIL import TiffImagePlugin
    import numpy as np
    import sys
    im = Image.open(file_tif)
    values=np.zeros((size_y,size_x))
    mode=im.mode
    temp=list(im.getdata())
    cont=-1
    list_colors=[]
    for i in range(0,size_y):
        for j in range(0,size_x):
            cont+=1
            if mode=="RGB":
                color=temp[cont]
                print cont,temp[cont]
                if color in list_colors:
                    index=list_colors.index(color)
                    values[i][j]=index+1
                else:
                    list_colors.append(color)
                    values[i][j]=len(list_colors)
            else:
                values[i][j]=temp[cont]

Best regards

German

You could have a look at PyTesser:

http://code.google.com/p/pytesser/

It depends on PIL to decode images and Google's Tesseract OCR engine
(run as an externl process), but apparently works quite well.

Why would the image go between greyscale and rgb?  In anycase, perhaps
the easiest solution is use np.resize on temp instead of the for
loops.  Then if you have tuples of rgb versus ints you can use
np.where()

Chris

Many thanks for your email.I want to read values from images in
grayscale or rgb, because the product that is coming from Arcmap could
be either.

The issue is that using PIL I get pixel values in the greyscale of 127
or rgb(0,0,0), where really I could see in Gimp that these pixels have
a different value. Looks like PIL can decode part of the picture and
another part of the picture not.

Also I tried today to read the pixel values of the picture using
temp=np.array(im) but still I got  some cells with a value of 127
where really the image has different values.

The only way to decode the picture was using freeImagepy, opening the
image with freeImagepy, saving and then open again with PIL to get the
values. It works but not in the way that supose to be. I want to do
all with PIL :-)
 (Attached is the code)

Many thanks

German

    from PIL import Image
    from PIL import TiffImagePlugin
    import numpy as np
    import sys
    import FreeImagePy
    FIPY = FreeImagePy.freeimage()
    image = FIPY.genericLoader(file_tif)
    FIPY.Save(FreeImagePy.FIF_TIFF, image, "temp.tif")

   im = Image.open("temp.tif")
   values=np.zeros((size_y,size_x))
   mode=im.mode
   temp=list(im.getdata())
   cont=-1
   list_colors=[]
   for i in range(0,size_y):
       for j in range(0,size_x):
           cont+=1
           if mode=="RGB":
               color=temp[cont]
               print cont,temp[cont]
               if color in list_colors:
                   index=list_colors.index(color)
                   values[i][j]=index+1
               else:
                   list_colors.append(color)
                   values[i][j]=len(list_colors)
           else:
               values[i][j]=temp[cont]

Check the inverse of the numbers, there are a ton of inconsistencies
of x,y and matrix representation.  Basically an image's x axis
progresses left to right, whereas a matrix's x is top to bottom (x,y
versus row,column).  So check 2,3 and 3,2 on GIMP, etc.

Message-ID: <201010270741.o9R7fugn024394@ruuvi.it.helsinki.fi>

Hello,

I've got libjpeg-devel installed, but doing a

python setup.py build

with a Python 2.6.6 install that I made myself, against Imaging 1.1.7,
results in no JPEG support.  The same process works just fine on i386
CentOS 4 (also with a custom Python 2.6.6), but not on this x86_64.

The JpegEncode.o and JpegDecode.o files in build/temp.SOMETHING/libImaging
get created in the process, but contain no symbols.  The compilation command

$ gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -DHAVE_LIBZ -IlibImaging -I/[PYTHON INSTALL]/include -I/usr/local/include -I/usr/include -I/[PYTHON INSTALL]/include/python2.6 -c libImaging/JpegDecode.c -o build/temp.linux-x86_64-2.6/libImaging/JpegDecode.o

goes through without errors.  I'm completely puzzled.

I would appreciate any help, and explicit personal cc's of any replies
as I am at present not a member of this mailing list.

Best regards,
