Subject: [IMAGE-SIG] Decoding Jpegs
Message-ID: <XFMail.980201042833.delmendo@cymitar.net>

I am running Red Hat Linux 4.2 
I installed  the IJG Jpeg Library Ver 6 from the Sig home page
I am using Python 1.5

I keep geting the following errors attempting to save/show jpegs

im=Image.open("whynot.jpg")
im.show()

Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "/usr/local/lib/python1.5/Imaging/Lib/Image.py", line 353, in save
    self.load()
  File "/usr/local/lib/python1.5/Imaging/Lib/ImageFile.py", line 148, in load
    d = _getdecoder(d, e, a, self.decoderconfig)
  File "/usr/local/lib/python1.5/Imaging/Lib/ImageFile.py", line 49, in _getdecoder
    raise IOError, "decoder %s not available" % d
IOError: decoder jpeg not available
>>> 

Does this mean I have incorrectly installed the jpeg libarary or is the image library inco
mpatible with Python 1.5?

Any help would greatly be appreciated.

AFAIK, it works just fine with 1.5; it's probably some configuration
problem.  Here's the quickest way to get PIL up and running under
RedHat 4.2 (and 5.0):

RedHat includes libz and libjpeg (in /usr/lib), so you don't need
to build them yourself. However, the 0.3a1 source kit assumes
that you have libjpeg 6.0 while RedHat ships with 6.0a.  To use
these libs anyway, do as follows:

1. goto libImaging and run configure as usual.

2. before you build the library, edit the ImConfig.h file so
that jpeg is enabled:

/* Define if you have the IJG jpeg library (-ljpeg).  */
#define HAVE_LIBJPEG 1                                                         

3. compile the library and look for warnings in the JpegEncode.c and
   JpegDecode.c files.  if you don't get any warnings, take another look
   at the ImConfig.h file, and make sure you don't have any other jpeg
   library on the machine (at least not in the linker library path)

4. change the METHODDEF and GLOBAL references in JpegEncode.c
   and JpegDecode.c from "METHODDEF int" to "METHODDEF(int)" etc.
   compile again, and make sure you don't get any warnings from
   these two modules.

4. when you have built the library, go back to the module library
   and copy Setup.in to Setup.  edit the latter so that libz and libjpeg
   are taken from /usr/lib.

you can also wait a day or two for the 0.3b1 source kit (which is
what I'm working on at this very moment, on a RedHat 4.2 box).

Cheers /F

Expect a 0.3 beta soon; this release was supposed to
be a beta, but I have a number of contributed patches

Congrats Fredrik,

Some experiences on RedHat 5.0 with source-built python1.5 and tcl/tk8.0p1:

o The 'test' directory was absent (!)
o The README introduces the demos and encourages trying them, before it 
  mentions the Tkinter embedding. This is confusing as most of the 
  demos depend on the latter.
o The python1.5 Setup has to be edited only by uncommenting the 
  WITH_PIL line. It might be a good idea to mention that the include
  path should mention the Imaging-0.3a3/libImaging directory.
o Image.py contained the line: from Types import IntType, etc.
  On UNIX Types has to be decapitalized.
o ./Tk/tkImaging.c contains a line:

   photo = Tk_FindPhoto(argv[1]);

  Dunno if this is a Tk4.2 vs Tk8.0 thing, but I got it to work by 
  adding the 'interp' as first argument:

   photo = Tk_FindPhoto(interp,argv[1]);

Look forward to 0.3beta :-).

This suggests a new function for the string module:

a clever enough compiler? ;-)

that reference was left in there by mistake; the ImagingCrack
function is called a static function which is not referenced from
anywhere else in the file, and both compilers used to test that
release (MSVC, Digital's cc) didn't generate any code for that
function.  gcc isn't that clever, though...

to fix this, grab 0.3a3 from http://www.pythonware.com

This is a libjpeg 6.0 vs. 6.0a problem.  Earlier releases was written
for the (relatively old) 6.0 release, which used "METHODDEF type".
In 6.0a, this was changed to "METHODDEF(type)".

In my copy of RedHat 4.2, there's a libjpeg 6.0a installed under
/usr/lib.  Maybe you have an older copy somewhere else?

Cheers /F

(and yes, I should have made it clear that this release required
6.0a in the news section and the changes document).

This is the first set of patches for PIL 0.3a3.  This fixes an import
error in Image.py ("Types" instead of "types"), a critical bug in the
Tk interface that caused compilation errors or segmentation violations
if you use Tk 8.0 final or a later patch release (note: after applying
this patch, you *must* use Tk 8.0 final or later), and a few minor
type mismatches that some compilers didn't like.

Many thanks to Case Roole and the folks at SMHI.

Hi!

I would like to have an example on how to use the

I tried with ImagePalette raw mode, but didn't succeed.

What I want to do, setting a new image palette to 
a 'P' type image and transform back to 'RGB' type.

Did you build your tkinter module yourself?  It looks like you accidently
named your DLL/PYD tkinter rather than _tkinter...

What happens if you start the interpreter and type:

    import _tkinter
    import Tkinter

Downloaded everything from where?  It definitely looks like
your installation is broken or mixed up in some way.

FYI: _tkinter is the low-level interface to Tk, Tkinter is the
high-level interface, but it's a Python module, not a dynamic
module.  Both modules must be present.

	Would anyone be interested in such a thing?  I was thinking that
it might be nice to merge CDX (a nice interface to DirectX) into python.
It would basically allow the use of DirectX from python... but since I'm
new to python, I'm not very skilled at creating these kind of
wrappers/modules yet. I'd like to be able to do full screen 640x480x256
color (at least) with sprites, maps (made of tiles), load and save
bitmaps, play sounds, play MIDI, etc. from python.  Sorry for the
off-topic stuff... is there a general mailing list?

I haven't looked into CDX, but I do have an alpha version of an interface
to MGL, which provides very fast graphics on PC's.  Check
www.scitechsoft.com for info on MGL.  Email me for info on the Python
interface to it.

More to the point: yes, definitely, build an interface to CDX.  But first
read about SWIG (http://www.swig.org), it'll most likely save you weeks of
work.

I've heard of MGL... is it any good?  Is the Python interface shaping up?
I'd like to find out more.  I saw a review of MGL on www.egerter.com (a
non-free competitor so it's biased) that kinda cut MGL to pieces - of
course: they're trying to sell PowerRender,WGT,etc.

I was thinking about SWIG... but I'm not really sure CDX is that
complicated - and it's in C++ so it won't be as simple as just making
interfaces for python to call C routines.  I'll need to make some python
classes, some python functiions, and make some C++ to create CDX and
manage the CDX objects and do things that really need to be as fast as
possible (like blit a list of sprites, blit the background, etc.).  If
you're interested, CDX is at http://www.maidex.demon.co.uk/.  It's really
a nice package and easy to program in C++... but I like to be able to
edit/run/edit/run without all the waiting to compile, etc., and hopefully
python+CDX will make all the nasty Windows+DirectX stuff disappear! 8-)

Re: MGL: works for me.  Some problems because of the stupidity of DirectX
support on NT (microsoft's fault -- they don't allow MGL to find out about
VBL, but that's not a problem for most folks).  It's easy to use, plenty
fast enough for what I do, and the documentation is very good.  The
price is definitely right.  I'll look at the review, but I'm happy with it
so far.

I'll look at CDX, definitely. SWIG can deal with a fair bit of C++ parsing
which may make it easier than you think -- it makes shadow classes in
Python, etc., etc.  I can't stress how great a tool SWIG is.
