The "autocrop" feature that it refers to means that oiiotool automatically
behaves as if they had specified --croptofull, if and only if outputting to a
file format that doesn't support separate data and display windows. That's the
default, and you turn it off with --noautocrop.
You're looking for something different -- if I understand properly, you want to
shrink the data window so that it encloses the minimal area with non-black
pixels, right?
There is no such functionality in oiiotool at the moment, but it would be easy
to add. I'll try to take a whack at it over the weekend.
