[PYTHON IMAGE-SIG] Reading, displaying, and manipulating sun-rasters

Seems as you've stumbled upon two problems with PIL at the same time:

1. Interlaced GIFs are not properly read, as I noticed myself
   a few days ago (found a "NYI" comment in the sources :-(.
   This is why the image looks so strange.  I'll fix this for
   the next release.

2. A (possible) problem with the type of Sun raster files you're
   using.  To help me track down this problem, could you mail me the
   output from pilfile.py?

	$ python pilfile.py -i <rasfile>

   And yes, what happens if you try to do "show" on that image.

	Image.open(file).show()

   If that fails, does this work?

	Image.open(file).convert("RGB").show()

Anyway, a quick workaround is to use PPM instead of GIF as the
intermediate format (or determine how to switch off interlacing in
ImageMagick).
