Hi guys!
I am sorry for posting threads, but I think this is the right approach, instead of asking 2 questions in 1 thread.
I have done ".jpeg" compression in C(DSP TigerShark processors), now I want to make a ".zip". The idea is to read a ".zip" file and uncompress it or to read a file and compress it.
Can anyone give me the formula and some basic explanations about the method. Please do not redirect me to other forums, books and etc.
Since you don't want to be redirected, you presumably have done your research but are stumped for some reason. So, how are you stuck?

I just need the formula. I know what a compression is and how to apply it. Also if there is some special procedure for the ".zip" compression(tricks of the trade).
Just a formula wouldn't be enough. I hope you're fine with reading technical documentation, because what follows is the ZIP specification:

If I wanted to read the documentation, I wouldn't ask for just the formula. Everything is a formula in life, especially in C, and when we add the tricks of the trade, from 100000000 pages you get 1 page.
zlib and RFC 1951 is what you are searching for...
That's obviously false: while a particular formula might be essential to an algorithm, not all algorithms can be reduced to a formula, unless you're using a non-mathematical meaning of "formula" such that it is equivalent to "algorithm".
Anyway, if you're not interested in reading the docs, why bother with implementing the algorithms yourself? A quick search of the Web shows that there are existing C libraries. Saves you the trouble of debugging too.

Thanks to both of you! Yes I meant non-mathematical meaning. I will look it up, but my searches until now were not successfull.
