hi,
 
sorry, if this is the wrong group, but all "compression"-
groups don't handle 'real' image compression.
 
o.k. my question:
 
i have seen a clip-art collection for PCs, that where
stored in "fractal compression methode".
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
they where NORMAL images (not fractals themself).
i think the theory is, that EVERY image could be stored als
a complex fractal function.

does anyone of you know implementations/sources of this method ?

Yes, this is the wrong group.  Try comp.compression -- fractal image
compression is covered in the FAQ posting there.

Actually, they were fractals.  They are encoded in such a way that the
specific fractal image is close to the original image -- it is lossy
compression.

>does anyone of you know implementations/sources of this method ?

Again, check the FAQ in comp.compression -- its covered there.
