1 Zopfli Compression Algorithm is a compression library programmed in C to perform 2 very good, but slow, deflate or zlib compression. 3 4 zopfli.c is separate from the library and contains an example program to create 5 very well compressed gzip files. 6 7 The basic functions to compress data are ZopfliDeflate in deflate.h, 8 ZopfliZlibCompress in zlib_container.h and ZopfliGzipCompress in 9 gzip_container.h. Use the ZopfliOptions object to set parameters that affect the 10 speed and compression. Use the ZopfliInitOptions function to place the default 11 values in the ZopfliOptions first. 12 13 Deflate creates a valid deflate stream in memory, see: 14 http://www.ietf.org/rfc/rfc1951.txt 15 ZlibCompress creates a valid zlib stream in memory, see: 16 http://www.ietf.org/rfc/rfc1950.txt 17 GzipCompress creates a valid gzip stream in memory, see: 18 http://www.ietf.org/rfc/rfc1952.txt 19 20 This library can only compress, not decompress. Existing zlib or deflate 21 libraries can decompress the data. 22 23 Zopfli Compression Algorithm was created by Lode Vandevenne and Jyrki 24 Alakuijala, based on an algorithm by Jyrki Alakuijala. 25
