ImageMagick? You're kidding! Let's say you have half a dozen bitmapped
images,
named frame1.bmp through frame6.bmp (no, you don't have to use those
names!).
You do this:
convert *.bmp final.gif
Where's the complication? :-)

For this, you'll need to do a bit of alpha-blending. Not difficult. I
actually
wrote a cross-fading program not so long ago, for precisely this purpose.
It
takes a set of .bmp files and a tween rate, and produces bitmap frames
that
fade from A to B, B to C, C to ..., etc, ... to Z, and Z back to A again.
ImageMagick then takes the strain of merging them together into a GIF.
(And before you ask, no, you can't use my cross-fader, unless you're
prepared
to part with some cash, which strikes me as being rather unlikely. But it
really isn't that difficult to write your own. If I can do it...)
