FreeImage

There is already (an old) Qt plug-in, listed in the main FreeImage page (http://freeimage.sourceforge.net/sourcecode.html)

May be you could check the way it is packaged.

Also, can you elaborate more on what the plug-in does and what allows you to do?

Im a Qt user also, and right now

It cannot be easier to use Fi with Qt!
Because both store images on compatible alignment (I guess) its is posible to call QImage constructor, passing the FI Bits and the dimentions, and Qt will use the image even without coping the pixel data! I use this all the time! (on windows)

Anyway, in general, I guess, it is possible to be included as separate project (folder) just as the other wrappers, but I doubt anyone will be willing to maintain it :(.
