[Numpy-discussion] [OT] any image io module that works with python3?

[Nadav Horesh]

Having numpy, scipy, and matplotlib working reasonably with python3, a major 
piece of code I miss for a major python3 migration is an image IO. I found that 
pylab's imread works fine for png image, but I need to read all the other image 
format as well as png and jpeg output.

 Any hints (including advices how easyly construct my own module) are 
appreciated.

On Windows, PIL (private port at 
), PythonMagick 
, and pygame 1.9.2pre 
 are working reasonably well for image IO. Also 
the FreeImage library  is easy to use 
with ctypes .

Here's a ctypes interface to FreeImage that I wrote a while back and  
was since cleaned up (and maintained) by the scikits.image folk:

https://github.com/stefanv/scikits.image/blob/master/scikits/image/io/_plugins/freeimage_plugin.py

If it doesn't work out of the box on python 3, then it should be  
pretty simple to fix.

I forgot to mention that I work on linux (gentoo x86-64).Here are my 
achievements till now:

1. PythonMagick: Needs boost which I do not have it avaiable on python3
2. Pygame: I have the stable version(1.9.1) should it work?
3. FreeImage: I installed FreeImagePy on python3, but it doesn't work yet.
4. PIL: I patched setup.py and map.c so "python3 setup.py build" is working, 
but:

Any idea on how to correct it? Any elegant way to avoid byte compiling?

You need the developer version from svn.

FreeImagePy is unmaintained, does not work on Python 3, and has problems 
on 64 bit platforms. Just wrap the functions you need in ctypes.

Re: [Numpy-discussion] [OT] any image io module that works with python3?

[Nadav Horesh]

It started to work after processing it with 2to3 and omitting the conversion of 
file names with the str function (I supply the file names as "bytes").
Issues:
  1. It refuses to save in jpeg format
  2. There is a worning of possible segfult on 64 bit machine (which is the 
target platform).

I'll keep on test it.

 Thank you
Nadav.

Py_FindMethod should be excluded by `#ifndef PY3` or similar 
preprocessor statements. There is a typo in map.c line 65: change 
`#ifdef PY3` to `#ifndef PY3` and clean your build directory before 
rebuilding.

Re: [Numpy-discussion] [OT] any image io module that works with python3?

[Nadav Horesh]

This lead to another error probably due to line 68 in map.h. As much as I could 
trace it, ob_type is a member of PyObject,  not of PyTypeObject. I have no clue 
how to resolve this.

Py_FindMethod should be excluded by `#ifndef PY3` or similar
preprocessor statements. There is a typo in map.c line 65: change
`#ifdef PY3` to `#ifndef PY3` and clean your build directory before
rebuilding.

I now fixed the scikits.image build process under Python 3, so this
should be easy to try out.

Line 68 in map.c is excluded by a preprocessor statement. There is 
likely another use of ob_type in a code that is not used on Windows. I 
have not ported _sane.c for example. I'll try to get access to an Ubuntu 
system and update the source.

Re: [Numpy-discussion] [OT] any image io module that works with python3?

[Nadav Horesh]

Jest tested the installation (after git clone ...). I had to correct the 
following lines in _build.py to pass installation:
lines 72, and 75 should be:
f0 = open(f0,'br')
f1 = open(f1,'br')

Thanks so much for testing and for the patch; I've pushed your changes:

Hi Stéfan,

I am sending you this off list.

I just tried scikits.image from git on Windows. The attached patch fixes 
some minor build and test issues.


Scikits.image.io occasionally seems to shadow Python's io module such 
that `import gzip` fails. There are 5 test failures like this:

I just tried PIL-1.1.7-py3 on an Ubuntu 64 bit system: after one change 
to map.c it builds OK (without sane support) and passes all tests but 
one numpy int64 bit related test. Please download again from 
<http://www.lfd.uci.edu/~gohlke/pythonlibs/#pil> to make sure you have 
the same sources and try build again.

Re: [Numpy-discussion] [OT] any image io module that works with python3?

[Nadav Horesh]

Just downloaded and got the same problems. I'll try to debug and provide a 
decent analysis, but it would take some days as I am busy with other things.

  Thank you,
  Nadav.

I just tried PIL-1.1.7-py3 on an Ubuntu 64 bit system: after one change
to map.c it builds OK (without sane support) and passes all tests but
one numpy int64 bit related test. Please download again from
<http://www.lfd.uci.edu/~gohlke/pythonlibs/#pil> to make sure you have
the same sources and try build again.

Thanks, that'd be appreciated; I am able to load images using
freeimage without a problem in Python 3 now.
