Gilles,

it is possible to set a higher threshold in
http://lxr.kde.org/source/extragear/graphics/digikam/libs/3rdparty/libpgf/PGFtypes.h#53
Set it to 31 to completely disable downsampling. However, no one should be able
to distinguish visually images compressed on q4 with downsampling en- or
disabled.

I recommend using the PGFconsole to experiment with encoding settings and
observing PSNR / size changes.
