Hi - I have a TIF which when I am try to read it with PIL I get
'IOError("cannot identify image file")'.In it's original form PIL can read it. I then use ImageMagick to change it's colour managment from RGB to CMYK (script A at bottom of email shows the windows BAT files used). At that stage PIL won't read the output. The output of TIFFDUMP applied to that image (ZENDGraphOutput-Step1.TIF) is shown below. However I read in an earlier post (http://mail.python.org/pipermail/image-sig/2008-November/005263.html) that some TIF headers are needed by PIL which are sometimes lost by intermediate process so I used ImageMagick and TIFFSET to put them back in place (script B at bottom of email). Unfortunately even after that PIL won't read it. The output of TIFFDUMP applied to that image (ZENDGraphOutput-Step2.TIF) is also shown below. Is there anyone out there who can see why PIL is choking on this TIF ? I would be grateful for any advice.
