[A83] Re: Compression




That's not true at all. The best sorts of compression involve arithmetic
compression and some sort of predictive modeling or dynamic contexts. But
the Z80 isn't fast enough for any of that. Huffman can often be good for
images. But for data and levelsets, I have found Lite86 to provide nice
compression, and it requires no extra memory. It will work for any
calculator, not just 86. It sometimes works well for images and sprites
also.

In compression, the best you can get for all thing(data, sprite, image) is
huffman but the "negative" of huffman is it need a 1024 byte buffer to
decompress.... So Hope that help
