  16. I don't know what sort of performance figures you have heard, but fractal
  17. image compression is for real. It is quite amazing, actually, to
  18. see it in action. It is my understanding that fractal graphics compression
  19. schemes are typified by long compression times (yes, searching for
  20. the fractal "patterns" is a pain), quick decompression, and excellent
  21. compression ratios.  The matter of image degradation vs. other
  22. compression systems (like JPEG), has not been clarified to me.
