Description:
The deflation algorithm used by gzip (also zip and zlib) is a variation of
LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
the input data. The second occurrence of a string is replaced by a
pointer to the previous string, in the form of a pair (distance,
length). Distances are limited to 32K bytes, and lengths are limited
to 258 bytes. When a string does not occur anywhere in the previous
32K bytes, it is emitted as a sequence of literal bytes. (In this
description, `string must be taken as an arbitrary sequence of bytes,
and is not restricted to printable characters.)

Description: This scheme is initiated by Ziv and Lempel [1]. A slightly modified version is described by Storer and Szymanski [2]. An implementation using a binary tree is proposed by Bell [3]. The algorithm is quite simple: Keep a ring buffer, which initially contains "space" characters only. Read several letters from the file to the buffer. Then search the buffer for the longest string that matches the letters just read, and send its length and position in the buffer. Platform: |

Description: Very simple class to ZIP and UNZIP files (Streams actually). Based on Ziv-Lempel basic algorithm.
Simple.. not fast nor really "compressive" :).
Create(A) a ZIP by passing in the stream A you want as source/destination. Call Add(B) to compress a stream B into A. Call Extract(B) to decompress stream A into B. Platform: |
