Somes tools around zLib built by Gilles Vollant, maker of WinImage and
Smartversion.



ZLIB is a compression library compatible with the gzip format. It has been
written by Jean-Loup Gailly and Mark Adler. It is free software.
The official page is there, but if you are interested only in Windows
95/98/NT/2000/XP/2003 support, you have found the right place.
There is also a page with a discussion list, Zlib-devel -- zlib compression
library development discussions.

This page contains stuff built around zLib by Gilles Vollant, maker of WinImage
and Smartversion.
It provides a DLL version of the library and pointers to other projects like
MiniZip. It also intends to offer support for the DLL version and for assembly
code optimisation.

NEW: the source distribution of the zlib DLL is now merged with the standard
zlib.



--------------------------------------------------------------------------------

Current version (1.2.3):

zlib123.zip - zlib-1.2.3.tar.gz - sources of zlib

 * You need that if you want to use zlib in your programs. Officially, zlib does
   not have a "programmers manual", but a quick read to zlib.h will make your
   ideas clearer.
   If you need a Visual Basic interface to zlib, see cmp-z-it.zip or
   http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm and
   contrib/visual-basic.txt

zlib123dll.zip - pre-built zlib DLL, compiled with the Microsoft Visual studio
2003 compiler (the compiler is available as free download)

 * This DLL is for Win32-x86. There is also a DLL for Windows 64 bits, for
   AMD64/Intel EM64T and for Intel Itanium.
   Make sure to define ZLIB_WINAPI before including zlib.h. Read
   contrib\vstudio\readme.txt file whithin zlib123.zip for more information.

zlib122asm_v1a.zip - Latest assembly code for zLib 1.22, both 32 bits (x86) and
64 bits (x86-64 for AMD64/Intel EM64T).

 * This file contains latest optimized assembler code for Win32-x86 and
   Win32-x64 (64 bits for AMD64/Intel EM64T).
   It also contains a makefile for testzlib for Visual Studio 2005, for
   benchmarking and tests. You can also get 64 bits minigzip for x86-64 Windows,
   and both x86 and x64, with and without assembly code testzlib binary (or a
   more complete distribution) for doing benchmarks. I worked also on MD5
   optimisation for AMD64.

--------------------------------------------------------------------------------

Previous version (1.1.4):

zlib114.zip [146K] (or through FTP) - sources of zlib

 * You need that if you want to use zlib in your programs. Officially, zlib does
   not have a "programmers manual", but a quick read to zlib.h will make your
   ideas clearer.
   NOTE: this archive is now THE SAME of the standard distribution.
   
   Take a look at the Users Corner.
   If you are going to rebuild the library by yourself, read the build
   instructions.
   If you need a Visual Basic interface to zlib, see cmp-z-it.zip or
   http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm and
   contrib/visual-basic.txt

zlib114dll.zip [94K] - pre-built zlib DLL

 * This DLL contains both Win16 and Win32-x86 versions.
   Make sure to define _WINDOWS and ZLIB_DLL before including zlib.h. You can
   get the additional build file (buildzlib114dll.zip) to recompile this DLL if
   you want.

If you want the complete version history for zLib (from 0.95 to 1.1.4), get the
multiversion archive zlib.svf, or, from 0.95 to 1.23, zlibnew.svf, and open it
with SmartVersion.

--------------------------------------------------------------------------------

Other projects:

Minizip package - Source code that enables to unzip files from a .ZIP file.

 * Formerly named "Unzip package", this package is based on Zlib.
   You will also find an excellent sample that adds a "Send as ZIP-File" command
   to the MFC Scribble sample. I have included the corresponding Visual C++ 6.0
   project.

sfondo.zip [34K] - full source & exe of an MFC app that uses ZLIB.DLL

 * This is a quick & dirty utility that allows you to compress BMP images with
   gzip to obtain better compression than GIF images, and still use them as
   background for your desktop.
   To use this program, you need ZLIB.DLL and the MFC30.DLL that comes with 95.
   

gzip124xN.zip [32K] - NT version 1.24 of GNU gzip

 * It works also under Windows 95.
