- You will find in this directory four files:
- - codecs.tgz V1.5 contains several compressers/decompressers
- - a description of CompuServe-Unisys copyright, file LZW-COPYRIGHT
- - this file, README
- - the file LISEZMOI, the translation of README, but in French
-
- Only the first file is compressed with 'gzip' and is a 'tar' archive.
- How to recover the orginal files?
-
- UNIX or DOS or any Operating system>gzip -d codecs.tgz
- UNIX or DOS or any Operating system>tar xvf codecs.tar
- You obtain a tree of directory with several codecs (coders/decoders) and a file
- with some explainations (in the file compress.txt).
- The tar file is no more useful and can be removed:
- UNIX or DOS or any Operating system>rm codecs.tar
-
- How to get tar and gzip programs? Just read comp.compression news group FAQ.
- A copy of FAQ of comp.compression news group is available by ftp in
- rtfm.mit.edu:/pub/usenet/news.answers/compression.faq/part[1-3].
-
- One of the codecs is an LZW codec. LZW is is covered by U.S. Patent 4,558,302
- and foreign equivalent patents, which are owned by Unisys Corporation.
- The code may not be used for commercial or for profit purposes or incorporated
- in another product, without first obtaining a license from Unisys Corporation.
- Please read file LZW-COPYRIGHT.
- Furthermore, the LZW codec of the package is more than a GIF encoder/decoder,
- since it is able to handle general LZW file (as GIF, TIFF, etc).
