nucleo/image/encoding/JPEG.cxx uses libexif to figure out the
orientation of JPEG images and automatically rotate them.
docs/installation.html lists nucleo's dependencies. As it says,
OpenGL (AGL or GLX), libjpeg, libexif, libpng, freetype2 and dns-sd
will be used if available at compilation time. But nucleo should
compile fine without them.
Among these, I think OpenGL is the only one you really need to build
the Metisse compositor. You'll need libjpeg if you want to be able to
take screenshots, though.
As a Mac user relying on Fink for libs that are not part of a
standard OS X installation, I tend to think twice before adding a new
dependency. libexif seemed small and stable enough to me. Have you
had any problem with it?
I could probably replace libjpeg, libpng and libexif with a single
image manipulation library. Suggestions are welcome.
One last thing: I will soon commit some files that add basic XMPP
support to nucleo. This code uses expat to parse XML and gnutls for
secured communications. More optional dependencies...
