[Image-SIG] Python Image Library problems with Tiff file using JPEG compression

[Leydon, Gary]

I've got PIL 1.1.7, Python 2.6.6, Libtif, libjpg, etc. Mac OS X 10.6.5. I've got some Tiff files with JPG compression , if I do

import Image

im = Image.open('myfile.tif')
im.info['compression']
'jpeg'

im.show()

I get the proper image but the colors are not remotely correct.

If I first do from the command line
tiffcp -c lzw myfile.tif lwfile.tif

python
import Image
im = image.open('lwfile.tif')
im.info['compression']
'tiff_lzw'
im.show()

The image looks fine

Is there some keyword or option or some other set of steps to open a jpeg compressed tiff properly and work on it with PIL?

thanks
