[comp.sys.amiga.tech] IFF 8SVX Compression

You are what you eat.

I would like to add two compression schemes to 8SVX files.  They would be 
a simple Huffman coding and a delta Huffman coding.  What is required to 
have these adopted or listed in the IFF spec? (or is something similar 
already there)  The only documentation I have is the RKM which lists the
fib compression and hints of better things to come.

I would also welcome ideas as to how to store the tree or table holds the
compression codes.  I am thinking it might require two hunks.  One would be
the BODY chunk and the other would be a TREE? chunk.  What I would like to
do is get compression codes assigned to put in the 8SVX chunk and define
a new type of chunk, tentatively called TREE.  I would then write an article
with code showing how to encode/decode these chunks and present sample code
to accomplish this.

I would appreciate information on the proper channels to contact and ask that
FLAMES and useless comments get replied instead of followed.  If I get 
useful information I will summarize.
