I think the fltk "resizing" just does (integer?) decimation of the source data... To get a "smoother" image you need to do some more complex interpolation/decimation process on the source data (functions that fltk does not provide for you.) So, you *might* be best linking in an image library to do that for you, if you need that functionality (unless you fancy writing your own, it might be fun!) Imagemagik and AGG both do smooth scaling of jpeg images, I assume all the many other image libs will do so too!
