when i try this: convert xaaa.tif dummy0.tif
the dummy0.tif will be displayed as negative when i try to embedd the Image into Microsoft Word.

i'm currently using version: ImageMagick 6.3.8 01/25/08 Q16 for Windows

Do you have any ideas, what i'm doing wrong?

Set your photometic interpretation like this:
  • convert -define quantum:polarity=min-is-white xaaa.tif dummy0.tif

Would this work the other way? I have printed rap sheets with forensic information on them which are totally reverse
in polarity when they conclude their operational process. I would like to flip the polarity on them so they look "normal".
