Description Tamas Haraszti 2007-06-01 14:05:36 UTC 
The PIL has an issue opening 16 bit TIFF files in big endian format.
Such files are common is scientific applications. 
I found the imaging-1.1.6 is affected.

I found a post from Zach Pincus in the URL cited above, containing a fair description and fix of the bug.

Reproducible: Always

Steps to Reproduce:
1.open any TIFFs with big endian data
2. check the pixel values or the image in show()
3.

Actual Results:  
One can find the bytes swapped from 16 bit big endian TIFF images.

Patch of Zach Pincus

After a bit of tweaking, finally this patch from the python mailing list worked for me.

The attached patch isn't that good, includes whitespace changes.

Patch applied in imaging-1.1.6-r1. Thanks.
