Data Compression Libraries for C programmers
The data compression libraries are specifically designed for the real time decompression of graphical sprite type data. They may or may not be suitable for other purposes.
Fast free UNZIP program, with C source
PCDEZIP decompresses .ZIP files created with PKZIP through version 2.04g. PCDEZIP provides syntax and switch compatibilty with both Michael Mefford's PCUNZP and Phil Katz's PKUNZIP. Although PCDEZIP does not handle encrypted files or files which span multiple diskettes, it does however, process ...
Huffman Encoding in C
The code implements Huffman variable length data compression algorithm to achieve a Minimum variance encoding. Its pretty well commented and for enhanced understanding, try uncommenting the "Temporary Debugging statements" within the huffman_encode() function. The code is well-commented and I hav g...
Huffman Tree Encoder 1
Huffman Tree Encoder is an implementation of the HUffman algorithm. I wrote a simplified version of the Algorithm for this program. The Algorithm is also available with the program. The program can generate codes for the symbols entered as well as display the tree for them. An included illustrat...
HuffMTF - Data compression by Huffman algorithm v1.0
A simple tool for data compression that uses two algorithms.A file to be compressed is first encoded using an MTF encoder which prepares the file for better Huffman compression.Then the Huffman algorithm is used on it for compression. With C sourcecode.
InfoZip ZIP 1,9p1 sources (for DJGPP)
Zip 1.9 is a compression and file packaging utility. It is analogous to a combination of tar and compress and is compatible with PKZIP 1.93a (Phil Katz ZIP) for MSDOS systems. There is a companion to zip called unzip (of course) which you should be able to find the same place you got zip. (See t...
LAR cruncher source in C
Lar is a Unix program to manipulate CP/M LU format libraries. The original CP/M library program LU is the product of Gary P. Novosielski. The primary use of lar is to combine several files together for upload/download to a personal computer.
LZ77 Compression Algorithm v0.1
This is an lz77 compression algorithm implementation. It compresses binary or ascii files but for educational purposes the output file is an ascii file in order to be readed from a human eye.
LZO -- a real-time data compression library v1.00
IS a data compression library which is suitable for data de-/compression in real-time. This means it favours speed over compression ratio. I named it LZO standing for Lempel-Ziv -Oberhumer. LZO is written in ANSI C. Both the source code and the compressed data format are designed to be portable ...
LZW Data Compression Library for C ver 1.4
DSCR: LZW4C is a data compression library for C programmers which uses the LZW algorithm as published in research papers by Lempel, Ziv, and Welch. The LZW algorithm is probably the best generic compression algorithm known today. Supports Borland Turbo C, Microsoft C, and MIX Power C.
Lzw lib is a library of functions that will allow you to do, in
your C programs, some of the things you can do from the dos commandline with such programs as pkzip and pkunzip, arc, lharc, etc. While i've titled the library lzw, your files can have any extension you desire. In fact, there is no default extension. You should be aware that these files will probabl...
Lzwa - lempel-ziff-welch-archiver a.4.2k
This little program is a Lempel-Ziff-Welch archiver. It supports adding/extracting of sub-directories, repairing of archive-header, testing archive, etc. C-source code included.
miniLZO
Mini version of the LZO real-time data compression library. I've created miniLZO for projects where it is inconvenient to include (or require) the full LZO source code just because you want to add a little bit of data compression to your application.
Portable lossless compression library - LZW/deflate (C)
This directory contains source codes for 'lzpipe' library, which implements two most popular compression methods: LZW and deflate. Both of these methods are de-facto lossless compression standards; LZW is used in well-known 'compress' utility and deflate is used by number of utilities starting ...
Run length Compressor v1.0
Compress your data using RLC/RLE. Best to use for BMP compression. Mail me for the code. The source code is of maximum 30-40 lines.
Six-2-Four - Exepacker for 4Kb-intros.
Beats the s*it out of Compack, PKlite, EXEPACK, DIET. Can only compress .com-filez, but who uses exe's anyway? Includes full sources (BC30 / TASM30).
UnZip Version 2.0, Zipfile Extract Utility
It is written to be as small and portable as possible -- ideal as a starting point for handling .ZIP files in non-IBM environments. Source code is provided in C and Turbo Pascal. If you port this program to a non-IBM system, I would appreciate a copy of the ported source and exec files.
WIZUNZIP 2.0 source files
This archive contains the source files which you can use to re-create WizUnZip 2.0. WizUnZip is a non-profit Windows unzipper product, based on the Info-ZIP group's product, unzip. Johnny Lee and I, who wrote the Windows interface code, have chosen to place our code in the public domain for you ...
