Another fractal compression program is available by ftp in
ftp://vision.auc.dk/pub/Limbo/Limbo*.tar.Z. It is also based on quadtrees,
as yuvpak20 and frac_comp.
The source code for the program published in the Oct 93 issue of
Byte is in
ftp://ftp.uu.net/published/byte/93oct/fractal.exe. This is
a self-extractible arc file (must be run on MSDOS for extraction).
The source code is for a TARGA video board. [Note from FAQ maintainer:
this code is taken from Barnsley's book "Fractal Image Compression";
it implements the brute force method and is thus very slow.]
Iterated Systems have released a beta version of their fractal imager.
It will let you view a number of formats including JPG and do
conversions to their fractal format. The program can be downloaded
from
"The Data Compression Book" (see [NEL 1996] in item 7 above) contains
a chapter on fractal compression; it includes source code for a simple
fractal compression program. The source is also available at
http://www.teaser.fr/~jlgailly/frac-1.0.tar.gz
Several fractal compression programs, including a volume coder, are available
