[Matplotlib-users] IOError: decoder jpeg not available

[Nils W. <nw...@ia...>]

Hi all,

I tried to read a jpg file.
How can fix the following problem ?

File "test.py", line 15, in <module>
     im = imshow(lena, origin='lower')
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/pyplot.py", 
line 1915, in imshow
     ret = gca().imshow(*args, **kwargs)
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/axes.py", 
line 5498, in imshow
     im.set_data(X)
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/image.py", 
line 282, in set_data
     self._A = pil_to_array(A)
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/image.py", 
line 751, in pil_to_array
     x = toarray(im)
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/image.py", 
line 736, in toarray
     x_str = im.tostring('raw',im.mode,0,-1)
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/PIL/Image.py", 
line 513, in tostring
     self.load()
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/PIL/ImageFile.py", 
line 180, in load
     d = Image._getdecoder(self.mode, d, a, 
self.decoderconfig)
   File 
"/data/home/nwagner/local/lib/python2.5/site-packages/PIL/Image.py", 
line 375, in _getdecoder
     raise IOError("decoder %s not available" % 
decoder_name)
IOError: decoder jpeg not available
  
Is it possible to plot different jpg's in subplots ?
