Compression Routines

[Lonewolf10]

Hi,

When studying compression routines at the end of 2005/start 2006 I wrote a simple compression routine which I got off the internet - well I got the theory behind how the code works, but I wrote a LZW (Lempel-Ziv-Welch) AMOS routine which is incredibly slow. Besides which, you would be stepping on a grey area if you don't have the appropriate license (the copyright to the LZW routine has expired, last I heard, but I wouldn't risk it).

Yesterday, whilst at work, I came up with a theory on how to do my own (hopefully much faster) compression routine. Unfortunately, with everything going on right now I won't have time to code it!!

Has anyone here written their own compression routine, and could it be used publicly, or perhaps within any NG AMOS?

I know some of the theory behind it but, if the PicPak compression routine doesn't pack enough, I usually use FImp and decompress it with the "Imploder Load" command on the AMCAF extension.

I wasn't particularly thinking of images, mainly music files as I have some great PD ones which are 100-200KB in size and am hoping to include 4 or 5 in a demo I am slowly working on. So slow, that I'm not expecting it to be finished until Xmas at the earliest.

FImp works on Protracker modules also.  In fact Imploder Load "filename.mod",-3 is the correct way to load a Protracker music module under the AMCAF extension.
