flateDecode filter

hy!

is there anywhere on the net an explanation (with some sort of 
pseudocode or source code) of the mentioned filter (i.e. the 
deflate/inflate algorithm)? i've looked around the net (been to zlib, 
but didn't understand it), but i can't seem to find it. the pdf 
reference from adobe says very little about that filter, it just states 
it's similar to lzw.

thanks very much,
doorman

The algorithm is at http://www.zlib.org/zlib_docs.html and you have
the zlib source code in C and ports to other languages.

Look at the bibliography, the part about RFC1950 and RFC1951.
I'm not sure what you expect to find other than this.
