Class: zlib
Description
Return a string containing the compressed buffer according to the given parameters. <syntaxhighlight lang="lua"> (string) = zlib.compress(buffer,level,method,windowBits,memLevel,strategy) </source>
Parameters
buffer: (string) string to compress
level: (number) compression level, 0 no compression, 9 best compression, -1 default compression optional
method: (number) compression method, should be 8 for this version optional
windowBits: (number) from 8 to 15, larger values of this parameter result in better compression at the expense of memory usage optional
memLevel: (number) 1 uses minimum memory but is slow and reduces compression ratio; 9 uses maximum memory for optimal speed optional
strategy: (number) 1 - Filtered, 2 - Huffman, 3 - RLE, 4 - Fixed, 0 - default optional
Return values
Returns (string) compressed string
