Zopfli Compression Algorithm is a compression library programmed in C to perform
|
||
|
|
very good, but slow, deflate or zlib compression.
|
||
|
|
|
||
|
|
The basic function to compress data is ZopfliCompress in zopfli.h. Use the
|
||
|
|
ZopfliOptions object to set parameters that affect the speed and compression.
|
||
|
|
Use the ZopfliInitOptions function to place the default values in the
|
||
|
|
ZopfliOptions first.
|
||
|
|
|
||
|
|
ZopfliCompress supports deflate, gzip and zlib output format with a parameter.
|
||
|
|
To support only one individual format, you can instead use ZopfliDeflate in
|
||
|
|
deflate.h, ZopfliZlibCompress in zlib_container.h or ZopfliGzipCompress in
|
||
|
|
gzip_container.h.
|
||
|
|
|
||
|
|
ZopfliDeflate creates a valid deflate stream in memory, see:
|
||
|
|
http://www.ietf.org/rfc/rfc1951.txt
|
||
|
|
ZopfliZlibCompress creates a valid zlib stream in memory, see:
|
||
|
|
http://www.ietf.org/rfc/rfc1950.txt
|
||
|
|
ZopfliGzipCompress creates a valid gzip stream in memory, see:
|
||
|
|
http://www.ietf.org/rfc/rfc1952.txt
|
||
|
|
|
||
|
|
This library can only compress, not decompress. Existing zlib or deflate
|
||
|
|
libraries can decompress the data.
|
||
|
|
|
||
|
|
zopfli_bin.c is separate from the library and contains an example program to
|
||
|
|
create very well compressed gzip files. Currently the makefile builds this
|
||
|
|
program with the library statically linked in.
|
||
|
|
|
||
|
|
To build the binary, use "make". To build the library as a shared Linux library,
|
||
|
|
use "make libzopfli". The source code of Zopfli is under src/zopfli.

Zopfli Compression Algorithm was created by Lode Vandevenne and Jyrki
|
||
|
|
Alakuijala, based on an algorithm by Jyrki Alakuijala.
