I don't know what your definition of "simple" is, but check out the
Python Imaging Library (PIL) at effbot.org.

Is there any package out there which handles Tiff Images other than PIL
or ImageMagic .
What sort of things do you want to do with the TIFFs? How
heavy-weight or light-weight are you interested in? For heavy-weight
there are:
- wxPython will do a bunch of tiff reading, and some image processing http://www.wxpython.org
- GDAL (quoting Khalid Zuberi:)
GDAL supports GeoTIFF and includes python bindings:
http://www.remotesensing.org/gdal/
- ITK Insight Toolkit from Kitware (wicked heavy-weight)
http://www.itk.org

nothing fancy. I just want to be able to read a tiff image, get pixel
values, write back to a tiff file.

[An aside: please quote the message you are replying to.]
Why doesn't the PIL satisfy this need? Or are you just collecting a list
of packages with this capability?

One reason why I don't want to use PIL is it seems very slow for tiff
images of very large sizes(2400x4800 ). So I am looking for a better
tool than does the right job faster.

This isn't fast enough?
In [8]: %time img2 = Image.open('foo .tiff')
CPU times: user 0.00 s, sys: 0.01 s, total: 0.01 s
Wall time: 0.03

When i try this i get this error:
import Image im = Image.open('ima ge.tif')
im.getpixel((10 ,19))
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "Image.py", line 858, in getpixel
self.load()
File "/usr/local/lib/python2.4/site-packages/PIL/ImageFile.py", line
180, in load
d = Image._getdecod er(self.mode, d, a, self.decodercon fig)
File "Image.py", line 328, in _getdecoder
raise IOError("decode r %s not available" % decoder_name)
IOError: decoder group4 not available

so why doesn't PIL or ImageMagick work for you?
here's a minimal PIL version:
from PIL import Image
im = Image.open("myf ile.tiff")
value = im.getpixel((12 , 34))
im.save("other. tiff")

Hi all !
I have a multi-page Tiff image file that I want to convert to PDF. To do so
I am using iText library. The conversion is working, but the code execution
is very different according to wich
iTextSharp.text.Image.getInstance(...) signature I am using :
- using code 1 below, the conversion is fast enough but the resulting PDF
file is too big (1 817ko sample Tiff file is converted in less than 30
seconds to a 2 764ko PDF file)

Hi,
I need to take few files (images in my case) and create one file out of
them, this file should be accessed so i can grab a single image from it
if necessary,
i thought of taking all the images and put them in one binary file, but
couldn't figure out a way to do that, anyone has an idea?
thanks

I can seem to get the dimensions of a frame in a multiframe tiff.
After selecting activeframe, the Width/Height is still really much larger
than the page's actual dimensions.
When I split a TIFF to several PNG files this causes a problem, becuase the
resulting image is (the page to the far left and a lot of black space
surrounding it and a filesize that is larger than needed.
Any ideas?

I have a web page and there is a link to open a TIFF file. The way I do it is
to have the server code open a binary stream, set the content type to
"image/tiff" and call Response.BinaryWrite. On the client machine, the file
type TIFF is associated with Kodak Imaging Preview. This app works on most
client machines. When you click on the link, Kodak Imaging Preview will open
the TIFF file on the client machine. However, on some machines, the...

I have the following class I use to save Tiff's. The problem I have with it
is that the final size of the images are very large. If we scan directly to a
file the final tiff may be 600-900 kb.s but with this code it is often
4000-5000 kb.s. What am I missing?
