I got it working this morning. The results are quite awesome, but
could use some tweaking.

To get it working, I had to:

* Remove the -S switch from the command line (added in run.py) so that
site packages would load on Debian
* Store the coverage object as a global in tester.py
* Have coverage load the previous results

Then just:

import coverage
cov = coverage.coverage()
cov.load()
cov.html_report()

We should probably look at this and see if we can improve it. Some of the  
last batch had been sitting around for over a month and that is not very  
nice for people just starting out with images and Python. Is this  
bottleneck with new members or simply approving e-mails?

How to open excel file in python?

I would like to plot multiple line joining the positions of each of the events, it is possible to do this? Have any idea how to do it?

The idea is to plot the trajectories on a particular region, for my case is Mexico.

My long term goal is to run mezzanine using virtualenv on a windows7 box.  I'm able to get mezzanine up an running but I receive a "decoder jpeg not available" error when I try to add images.  It appears that libjpeg did not get installed. I used "pip install mezzanine" which installed pillow as a dependancy.  Do I need to manually install libjpeg first?  How would I go about doing that on windows7?  Any assistance would be very much appreciated.

Hi.
In case you do not know yat.
_imagingft.pyc, necessary for ImageFont, has a dependency on the visual 
C++ debug runtime.
A part of it must not have been compiled with the "release" mode.
This prevent anybody without VC2008 to load fonts.

Message-ID: <CAJYf95viq60hJ1XxYNoeOCxVX374Ee2i9qQuTZ4AkZ2GrkfNoQ@mail.gmail.com>

Respected sir/ madam
                                 I have recently started coding for my PG
project in python imaging library. I encountered a problem of calculating
mean of a gray scale image after taking the log transform on the image. I
am putting the code below.

Import Image
import ImageOps
from numpy import *

im = Image.open('File name')
im_gray = ImageOps.grayscale(imj)
im_gray_mean = meanj(im_gray)

Now the value in im_gray_mean is showing to be -inf. I want this to be some
valid numeric data. Hope to hear from you at the earliest.

Yours sincerely
T.V.Chandra shekar

Subject: [Image-SIG] PIL image size after rotate
Message-ID: <509F230A.8090506@gmail.com>

Listers,

I have a very simple script that rotates images using PIL.  After 
running, the output images are about 1/3 the file size of the input 
image.  The file attributes indicate they have increased in resolution 
from 72 to 96 ppi but have the same radiometric depth. Does the PIL 
rotate method apply a hidden resampling? Why are the output images so 
much smaller?

from PIL import Image
import glob, os

indir = r'C:\Users\Me\Pictures\export'
for infile in glob.glob(indir + '\\' + "*.jpg"):
     print infile
     file, ext = os.path.splitext(infile)
     im = Image.open(infile)
     im2 = im.rotate(270)
     im2.save(file +"_rotate.jpg", "JPEG")
    #  os.remove(infile)

Subject: [Image-SIG] using PIL's split command with color jpg file .. help
 for color jpg file
Message-ID: <714690.1352916183811.JavaMail.root@mswamui-valley.atl.sa.earthlink.net>

I'm using python 2.7 with PIL 1.1.7.

I figure out how to work with black and white .jpg files.  

I ended up writing a bunch of programs to do some very interesting/cool image process effects as to learn more about image process. 
I own a small number of books on the topic of image process and have done some imagine programming in PASCAL and C
in the past too.  

I'm using PIL software to read in the .jpg files & simple functions and then writing my own image processing functions/programs 
as learning process for developing my skills for work.  I have used some of PIL's image process routines provided as well.

I'm now wanting to be able to do the same thing with color jpg files.

But I'm running into problems using the split function. The program quits on the command line
having to do with split function and the error is about no bands defined.

Can some body please provided a simple working program that show uses the split function 
as to access the 3 colors of a .jpg file.  I have looked at the PIL hand book but the information 
appears to be incomplete at this time for using split function.  

I get much mileage out of studying a good sample but simple program that shows the interaction of the functions 
required to do a given task and/or process.  

I notice the PIL web site appears to provide NO sample programs to study and play with at this time.

I'll be game to provide some of the programs that I came up working with BW .jpg files. 

Thanks

Jason

Hello,

On Windows 7 (with Python 2.7 32 bits), Image.show() doesn't work (the 
temporary file is deleted before Viewer.exe can load it). Here is a fix: 
line 99 has been changed into
             return "start /wait %s && sleep 20 && del /f %s" % (file, file)
(WindowsViewer is similar to MacViewer)

> How to open excel file in python?

>From Excel, save the file as a csv file, rather than a proprietary
format.  Then, within Python program, use the csv module,
    http://docs.python.org/2/library/csv.html


The essential parts:
import csv
def  getdata(filename):
    with open(filename, "rb") as infile:
        csvreader = csv.reader(infile, delimiter ="\t", quotechar='"')
            for row in csvreader:
                ---- process row ----

where row comes back as a list of items.

You may have to play with the delimiter and quotechar, as I don't use
Excel itself, to know what it defaults to.  But a csv file is a text
file, so it should be pretty obvious if you just look at the file with a
text editor or viewer, what the separator and quote characters are.  The
quote character generally only matters if some field has an embedded
separator or newline in it.

Try matplotlib:    http://pypi.python.org/pypi/matplotlib/1.1.0
It depends on numpy:   http://numpy.scipy.org/

Subject: [Image-SIG] Current libraries for image processing?
Message-ID: <CAPGiC77kG6aRSj_U5EPNi2u30XN2X0uXY4QeURfg7oODDh=iPA@mail.gmail.com>

I'm just starting to investigate Python for image processing, and I'm very
impressed (up to now my main software has been Matlab and its alternatives:
scilab, Octave etc).

What I want to know is, what is the current state of the art with regard to
image processing libraries?  Is PIL still an active concern?  Or should I
concentrate on scikits-image, scipy/ndimage, mahotas...?

Thanks very much,
Alasdair
