There are two possible reasons for your problems:
- FOP 0.92beta introduces some support for color profiles which is
actually to improve the quality of the overall process.
- ...but FOP 0.92beta has a bug: It may assign an sRGB color profile to
an image the is not supposed to be in the sRGB color space so the color
may come out wrong. This particular bug has been fixed in FOP Trunk
(from the SVN repository).
If you could try without JIMI but with FOP Trunk....... At any rate,
there are no special procedures to influence image handling. But it
could be that there is still another bug lurking somewhere.
