Subject: [Image-SIG] sane.py return incorrect value for options with same
 name as scanDev attribute
Message-ID: <5050C106.5000502@control.lth.se>

sane.py return incorrect value for options with same name as scanDev 
attribute (found while trying to get the value for the 'scan' button on 
a Canon Lide 110 scanner).

A simple patch is provided, but IMHO the sane.py module could do with 
some cleaning up (how about making it more object oriented...)?

Attached is a non-reversed diff, fixing some more calls, and making 
'open' and 'get_devices' automatically calling '_sane.init'.

ImageView.py has a bug on Unix where if the user has both display and
xv installed, a call to image.show() results in the image being shown
first with display and then with xv. This is because the show function
in the file expects the show method to return 1 if successful, but it
doesn't return anything. This patch fixes that.

Subject: [Image-SIG] Paste error in subplots using PIL and matplotlib.pylab
	on MacOS X
Message-ID: <4AEADB6D-CE41-4549-9020-71126B9364B1@iap.fr>

Dear PIL gurus,

I try to paste the same series of images (the Solar System planets) on two subplots of the same figure. The following loop is within a loop on the two subplots :

    print 'Processing Solar System'
    for FileImage in ListImages:
        Planet = os.path.basename(FileImage)[:-9]
        print 'Processing planet', Planet
        PlanetData = SolarSystem.where(SolarSystem.Planet == Planet)
        PlanetImage = Image.open(FileImage)
        if PlanetData.Radius[0] < 2.0: ZoomPlanet = ShrinkTellur * PlanetData.Radius[0] / Earth.Radius[0] * EarthImage.size[1] / PlanetImage.size[1]
        else : ZoomPlanet = ShrinkGiant * PlanetData.Radius[0] / Jupiter.Radius[0] * JupiterImage.size[1] / PlanetImage.size[1]
        PlanetResized = PlanetImage.resize((int(PlanetImage.size[0] * ZoomPlanet), int(PlanetImage.size[1] * ZoomPlanet)))
        Alpha = PlanetResized.split()[3]
        Alpha = ImageEnhance.Brightness(Alpha).enhance(Opacity)
        PlanetResized.putalpha(Alpha)
        if SubPlot == 1: Factor = 1.0
        else: Factor = SnowFactor
        PlanetX, PlanetY = XPixMin + (np.log10(PlanetData.Distance[0] / Factor) - XScalMin) * XFactor, YPixMax - (np.log10(PlanetData.Mass[0]) - YScalMin) * YFactor
        XSize, YSize = PlanetResized.size
        PlanetPos = (int(PlanetX - XSize / 2.0), int(PlanetY - YSize / 2.0))
        PlotImage.paste(PlanetResized, PlanetPos, PlanetResized)
        PlotImage.show()

The show() method proves that everything is fine unless the second subplot is processed: the images on the first one are erased. The images below are obtained by commenting the canvas.draw() instruction, thus anything has been removed but the pasted images. The first one is the first subplot well processed, second subplot still blank, the second is the next subplot, first planet. It is clear that all images have been erased from the previous subplot.

I use the latest PIL version with Agg backend and :

Enthought Python Distribution -- www.enthought.com
Version: 7.3-1 (64-bit)

Python 2.7.3 |EPD 7.3-1 (64-bit)| (default, Apr 12 2012, 11:14:05) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

Any hint welcome,
Cheers

Subject: [Image-SIG] bug report: PIL install does not find libjpeg...
Message-ID: <20120920091827.GA4001@capeo>

Hi!

"pip install PIL" fails in finding libjpeg, zlib, ... resulting in
multiple "*** LIBNAME support not available".

The reason is that PIL setup.py does not look for libs into
/usr/lib/x86_64-linux-gnu, where libjpeg, zlib and other are located.
The provided patch solves the issue.

I am using debian sid x86_64, but I am sure this bug affects other people.

Regards,

Message-ID: <724C18376B29C549A948B7745110F02FDA7C2E@FMSMSX106.amr.corp.intel.com>

Hi, I am having trouble installing PIL 1.1.7 for Python 2.6 for Windows 7. I get the error message:

"Installation requires Python 2.6, which was not found in the registry"

I used the script found here<http://effbot.org/zone/python-register.htm>, and added some print statements. The script runs with the following values:

version = 2.6
installpath = C:\Python26
regpath = SOFTWARE\Python\Pythoncore\2.6\
pythonpath = C:\Python26;C:\Python26\Lib\;C:\Python26\DLLs\
QueryValue(reg, installkey) = C:\Python26\
QueryValue(reg, pythonkey) = C:\Python26\Lib;C:\Python26\DLLs;C:\Python26\Lib\lib-tk


After running the script, it prints:
*** Unable to register!
*** You probably have another Python installation!

Therefore, the register key is opening successfully. The QueryValue results seem to be very close to the expected values (installpath and pythonpath).

Any suggestions why the PIL installer is not seeing the Python interpreter, despite it being located where it would be expected, and the key being found in the registry? I would appreciate any suggestions.

Thanks,

Reid

Is there anyone who can help me solve this problem? Thanks.

Dear friends,

 

I am  using Python 2.7.3.

 

I like to transfer a image file via python to RabbitMQ so I configured
image lib in my system.

 

I am using the below program for the image transfer 

 

channel.exchange_declare(exchange='testing_room1',type='direct',durable=
True,)

channel.queue_declare(queue='Testing', durable=True)

data="D:\\P.jpg"

file=jpeg.compress(data, w, h, b)

message =file

channel.basic_publish(exchange='testing_room1',routing_key='testing',
body=message)

 

But I am getting the error while running the program. Requesting your
guidance.

 

Thanks and Regards 

 

Robert tona felix.J
