[gentoo-user] USE flags confusing on emerge gimp

[Harry Putnam]

After some resent discussion here of USE in thread:
   Subject: How to play quicktime (*.mov) videos with firefox

I'm a little confused by what I see when investigating the emerge of
gimp (wrapped for mail).

  Calculating dependencies... done!
  [ebuild  N    ] media-libs/babl-0.0.22  USE="-mmx -sse" 388 kB

  [ebuild  N    ] media-libs/gegl-0.0.22  USE="svg -cairo -debug -doc
   -ffmpeg -jpeg -mmx -openexr -png
   -raw -sdl -sse -v4l" 1,226 kB

  [ebuild N ] media-gfx/gimp-2.6.6 USE="alsa python svg -aalib
   (-altivec) -curl -dbus -debug -doc -exif -gnome -hal -jpeg -lcms -mmx
   -mng -pdf -png -smp -sse -tiff -webkit -wmf" 15,700 kB

Would anyone want things like -jpeg, -pdf, -png, -tiff, -exif - turned
off in an image (or photo) processing program?

What does it mean that those flags are turned off?
Should I turn them on before emerging?

seriously, are you using some very old server profile or something like that?

I agree with Volker, you must be using some profile which has disabled
them. Please post the output of "eselect profile show"

Yes, definitely. If you only want gimp to process the photos from your
digital camera you only need support for one format.

That you are using a minimal profile when you really want to use a more
generic one, like desktop, as others pointed out.

> Should I turn them on before emerging?

If you want support for those formats: yes.
