PIL for Python 2.4?

[Christos TZOTZIOY Georgiou]

Has anyone built PIL (1.1.4 or 1.1.5) for Python 2.4? If yes, please
let me know, since I can't test a couple of my apps using PIL with 2.4 .
You can even reply by email (yes, I dare use true email in newsgroup
postings, but then, I'm postmaster and welcome spam

TIA

I haven't. But it would have been useful if you had mentioned which
platform ;-) Windows?

Oh, yes, Windows... On Linux I built it myself. I just don't have
access to a MS compiler on Windows.

Sorry for not being clear.

well I have old MS VC++ 6 and building with setup.py Python 2.4b2 gives an error
related to the compiler; I guess I need MSVC++ 7.

I have MSDN subscription, but no idea whether I can get 6 & 7 to coexist.

well I have old MS VC++ 6 and building with setup.py Python 2.4b2 gives an error
related to the compiler; I guess I need MSVC++ 7.

I didn't even *try* to build it on an installation of MS VS 6 we have in
the office because I remember the long discussion about the transition
to VS 7, and the need for the building of other libriaries with VS 7
too... Of course, I could completely build Python 2.4 with VS 6 and
then build PIL, which is what I'll do next. I just wanted to avoid
troubles with VS 6 project files being out of sync, so I asked if anyone
did the build.

Thanks for trying though.

I had a few problems building 2.4b2 on 6; I think the old projects are unmaintained.

You need 7.1, not 7.0. Aka named Visual Studio .NET 2003.

And it coexists with 6.0.

Thanks Thomas, I'll have a go at installing it soon.

You can download Microsoft's C/C++ compiler for free. (It's command
line only, but good enough.)

Thank you! Thank you! Thank you! Now that you told me I remembered
I'd read about it and completely forgot... ...and thank you!

[... windows ... replies from others on using the MS VC 7.1 ...]
Note that if you install MinGW, distutils can build acceptable
files with it. Since I believe I remember the PIL stuff is set up
to build with distutils, you should be able to get it going that way
as well.

I tried building PIL with mingw recently and had some failures I can't
remember ...

It *did* make me think "I wish there was some Pure Python image-handling
code". It seems like the C linkage is mainly required for image
formatting handling - I couldn't find any JPEG reading/writing code in
Pure Python ... would be nice

if you don't report your build problems, they will never get fixed (the
image-sig is the right forum for this, and the best place to get answers
to PIL-related questions).

and incredibly slow. PIL uses C for a reason.

Thanks, I'll try reproduce and mail it there...

I've recently discovered you can use the EXIF module to read thumbnails
that are embedded in a JPEG or TIFF file without having to parse all the
JPEG stuff. All I'm doing for my particular task is creating thumbnails
- I can imagine that this may be reasonably fast within Python.
Even if it was slow, it wouldn't neccessarily have to be *incredibly*
slow

I couldn't resist it... I found a C++ simple (and imperfect) JPEG parser
(http://www.codeproject.com/bitmap/TonyJpegLib.asp) and converted it by
hand to pure Python ...
It can basically decode most JPEG files and then output the result as a BMP.
Not surprisingly, it's fairly slow. Using Psyco can speed it up.
Here's a table of a brief test, image size and execution time under
Standard Python and Psyco running on my Athlon
Image Size | Standard Python | Psyco
photo, 2048 x 1536 | 32 minutes | 46 seconds
cartoon, 604 x 446 | 16 seconds | 4 seconds

I would guess that the algorithms being designed for C is a major
factor, and that doing some simple recoding would speed it up a fair bit.

I've put the code at http://davidf.sjsoft.com/files/pyjpeg/
I wrote a basic BMP format handler as well that the test handler
requires so that's there too.

Note 1: I am only beginning to understand JPEG from converting the code
And the original C++ code doesn't convert the image perfectly, it
has plenty of smudges which my Python code faithfully reproduces

Note 2: The code is horribly ugly for Python code

Anyone welcome to clean and speed it up...

It's a cute toy; Tkinter can be used to (slowly) show the jpeg image.
(I think there is a bug for images with sides not divisible by 8.)
