Deflate Algorithm - Deflector Stream Format - Documentation Beyond RFC1951

I am interested in documentation on deflation stream format or descent algorithm that is outside the scope of RFC1951. Examples of streams, implementation hints that might be interesting.

I've been working on a streaming deflate implementation and found this description helpful:

I tried the zlib source first, but it's not easy to read.

Could you just use zlib instead of rolling around on your own?

To support precompressed preambles, you can:

Use the original API (the ones that use z_streamp

as a parameter), not higher level wrappers.



Initialize the compressed preamble with your own z_streamp

and buffer the output.

Then, for all subsequent uses of the preamble, copy the output preamble buffer to the output and copy the preamble z_streamp

and use that copy to compress subsequent bytes.
