Subject: [Image-SIG] manipulate 16 bits Grey matrix
Message-ID: <CANYxx=wGfVjG0ctxmM+coMDWmwvsukRv3eD+PrB9oSc_KLoXJw@mail.gmail.com>

Hi all,

I have a 1394 cam that has a 16 bit greyscale output.

How can I handle this under PIL ?

Matrix has this shape : [ [  ][  ] [  ]...] and come frome libdc1394
wrapper. 8 bit is well recognise and treated :
---------8 Bits----------

matrix = cam0.current_image
i = Image.fromarray(matrix)

i.save("mypicture.jpg") (or png, or bmp ...)

---------16 bits----------
(code found somewhere)
    matrix = cam0.current_image
    if j ==0 :
        print matrix.size, len(matrix[0]),type(matrix)

    ## 'F' correspond au mode de conversion : F pour Float, bien s?r
## [667,800] est la taille de l'image ? cr?er, dans mon cas

        img = Image.fromstring('F',[480,640], matrix)
        nom = "t"+str(j)+".tif"
        tiff = nom
        fim = open(tiff, 'wb')

## Et conversion en entiers, en pr?cisant le nombre de couleurs...
        img = img.convert('I', colors=65536)

## Sauvegarde au format TIFF. BMP, JPEG, PNG ne sont pas compatibles
## avec le format des donn?es
        img.save(fim, 'tiff')

        fim.close()
----------------------------
---> result
Mode: 640x480_Y16    <- 16 bits OK for cam !
Framerate:  30
307200 640 <class 'pydc1394.camera.Image'>   <-  lenght of string, width
Traceback (most recent call last):
  File "16save_image.py", line 78, in <module>
    img = Image.fromstring('F',[481,641], matrix)
  File "/usr/lib/python2.7/site-packages/PIL/Image.py", line 1797, in fromstring
    im.fromstring(data, decoder_name, args)
  File "/usr/lib/python2.7/site-packages/PIL/Image.py", line 594, in fromstring
    raise ValueError("not enough image data")
ValueError: not enough image data


I really don't see what the problem...

Thanks for response.

Does it happen with Pillow too? If so, please report the issue here:

Message-ID: <7A94ED6DA25EF64186ED0311D29686C51DEBBEEA@DE-HV1-EX8.tuv.group>

Dear Madam/Sir,



I am using Python 2.7 and I am trying to install Python Imaging Library 1.1.7.

However, there is a problem and the installation stops with message:

" pil-1.1.7 win32-pu27.exe has stopped working "

How can I fix this problem?



Sincerely,

Mark Lam

Message-ID: <1358872701.1820.YahooMailRC@web181304.mail.ne1.yahoo.com>

Help needed.  I am having problems trying to install PIL for Python 2.7.  I get 
a dialog box that states that 2.7 in not registered.  I use Windows 7 as my 
computer operating system.  I also have Python 3.3 installed. Could that be the 
problem?

Thanks for your help,

John

Message-ID: <FB89C57FA266A9408F0B1B0F40173605416EE22D@USSLMMBX002.net.plm.eds.com>

Does anyone know of a module that will quickly determine whether two given triangular meshes are within a given tolerance of each other? Or perhaps point me to the right Python forum to ask this question?

Many thanks,
Julio
