[Image-SIG] What's wrong with this TIF ... IOError("cannot identify image file")

[Florian Höch]

Hi, it has nothing to do with missing TIFF headers.

PIL can't process 16-bit/channel images. You can use -depth 8
option in your ImageMagick commandline to force 8-bit/channel output
(as the original image is also 8-bit, I assume you use the Q16 version
of ImageMagick which always converts to 16-bit for supported fileformats
on output if you don't tell it otherwise).
