compression - What is the best way to load a CCITT T.3 compressed tiff using python? -

-

I am trying to load a CCTT T.3, which is in python, and get pixel matrix from it . It should be just a logical matrix

I have tried to use Pilibitif and public relations, but when I load it with them, the matrix comes back. I have read in many places that these two tools support loading of CCITT, but not reaching the pixels.

I am open to changing the image, as long as I can get the logical matrix from it and can do it in Python Code. The crazy thing is that if I open one of my images in the paint, save it without any change, then try to load it with the yellowbitiff, it works paint it compresses again for LZW compression is.

So I think my real question is: Is there a way that morally loads CCITT images from metric or converts the LZ into images using the illustration ??

thanks,

The way the dragon can not be fully used, lean on: 

  import image import image file import subprocess quarrel = 'test.tiff' im = Image.open (quarrel) Try print 'size', im.size: print 'extrema', leaving IOError as e: print 'help!', 'E', 'print' I received from my friends with some help 'pbm_proc = subprocess .Popen (['Tifftopnm', tiff], stdout = subprocess.PIPE, stderr = subprocess.PIPE) (pbm_data, pbm_er Ror) = pbm_proc.communicate () ifp = ImageFile.Parser () ifp.feed (pbm_data) im = ifp.close () print 'conversion message', pbm_error, print 'extrema', im.getextrema () print 'size' , Im.size # houston: We have an image im.show ()

move: 

  $ python g3fax.py size (1728) , 2156) extrema help! Decoder Group 3 is not available. I get some help from my friend conversion message with a little help: tifftopnm: PBM file extrema (0, 255) size (1728, 2156)

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
