In any case, the LZW patent is now firmly

not be a reason to avoid a particular compressed

outperformed LZ78 variants like LZW.

LZW was the first compression method I am
able to understand and use... although the
compression/decompression does get very
slow.
I understand the (fixed) Huffman method in theory,
but am currently unable to implement it. I
certainly wouldn't even know where to start
for the variable Huffman method :(
Has anyone created their own compression
method or have any pointers for someone
wanting to create their own?
