Thanks for the link.
Uhm... no, digikam does not use KDcraw::extractRAWData(). It uses
KDcraw::loadFromDcraw() instead, which then calls dcraw_make_mem_image()
(http://lxr.kde.org/source/KDE/kdegraphics/libs/libkdcraw/libkdcraw/kdcraw.cpp#679).
LibRaw docs do not mention the format of the data, but in
LibRaw-0.8.4/samples/mem_image.cpp there is a comment that says: "data in
img->data is not converted to network byte order. So, we should swap values on
some architectures for dcraw compatibility".

I think we should fix digikam. If we change libkdcraw we may break some other
apps which already convert the data.
