It's strange ... on coming home, I see that my machine here can display

I'm still curious what that "USE flags" section in the package document
represents.
Without fetching an out-of-date repo I have no idea what 7.0.8.11
supported as it is no longer in the repo. However, 7.0.9.8 supports:
equery uses '=media-gfx/imagemagick-7.0.9.8'
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-gfx/imagemagick-7.0.9.8:

How are you coming to this conclusion?

That's good, the equery example.
