Hello Everyone,

I've been pythoning for over a year now, but haven't used PIL until 
just recently.  I have a question -- has anyone successfully used 
GeoTIFF with PIL?  I have tried to read .tif files for USGS DRGs, 
which are GeoTIFF, but they don't work properly:

r>>> ima=Image.open('d:\\data\\python\\src\\drg\\test.tif')
>>> print ima.format,ima.size,ima.mode
TIFF (5419, 6804) P
>>> ima.show()
Traceback (innermost last):
  File "<pyshell#18>", line 1, in ?
  File "C:\Program Files\Python\Lib\Pil\Image.py", line 694, in show
    _showxv(self, title, command)
  File "C:\Program Files\Python\Lib\Pil\Image.py", line 972, in 
    file = self.convert(base)._dump(format=format)
  File "C:\Program Files\Python\Lib\Pil\Image.py", line 415, in 
    im = self.im.convert(mode, dither)

[NOTE:  Same thing happens in Linux-Mandrake 7.1]

Any ideas?  I know that GeoTIFF adds some attributes to the TIFF 
file, so that may be breaking it.

THANKS for any advice.
