I have posted an app based on my Image Gump shell that does some Fast
Fourier image transforms.

It isn't fancy, but can make a pretty picture, and you don't even have to
know how it works. :)

The beastie is commented well I think and demos also an implementation of
the following:

Importing a Quicktime image
Getting an image rect, setting also.
GWorld pixel poking and getting
FFT Forward and Reverse, with option for Forward RGB (slow)
Image invert
Save as Pict
Save as JPEG.

So on and so forth. It is a 415K download, binhexed, includes app, source,
and original C source the FFT is based on, courtesy Paul Bourke's site. URL
in the archive.

No guarantees of correctness, proper function or anything other than that
it seems to work.

Free.


This is an FB 3 project requiring Release 5 because of the dynamic arrays,
though you can certainly work around that using any release below that just
by changing the DIM conventions.
