compress

 

 

Overview

The compress function uses the extremely fast LZRW1 compression algorithm, by Ross Williams, to convert a Byte Vector, String, or Symbol into a much smaller Byte Vector.

Usage

Use the compress function to reduce the size of the iput Byte Vector, String or symbol argument.

 

Syntax

Expression:

(compress input)

Arguments Name Type Description
Argument:inputByteVector String Symbol Byte Vector, String, or Symbol to be compressed.

Returns:

A Byte Vector that contains compressed version of the input.
