convert(1) has quite a bit of complex code to do non-integer
image resizing.
ImageMagick is a full on image management library, so expect
it will have much better image resizing/enhancement capabilities
than what I expect is probably simple integer resizing in fltk.
To do proper resizing outside of simple 'power of two' changes
usually involves linear or gaussian interpolation of pixels to
prevent artifacts.
You can link in ImageMagick to use its libraries to do more
advanced image manipulation, or try to limit your resizing
to power of two scaling.
