CompressZlib(Byte[],Int32,Int32,Stream,ENCompressionLevel,Boolean) Method

In This Topic

Compresses the given bytes with the zlib algorithm.

Syntax

public static void CompressZlib( 
   System.byte[] input,
   System.int startIndex,
   System.int count,
   System.IO.Stream output,
   ENCompressionLevel compressionLevel,
   System.bool closeOutputStream
)

Parameters

input: An array of bytes to compress.
startIndex: The index in the byte array the compression algorith should start working at.
count: The total number of bytes from the byte array that should be compressed.
output: The stream to write the compressed data to.
compressionLevel: The compression level to apply.
closeOutputStream: Determines whether to close the output stream when the compression has finished or not.

Remarks

The zlib algorithm is an abstraction of the deflate algorithm used by the gzip compression and has become very popular because of its great performance. It is used in many file formats such as ZIP, PNG, PDF, flash movies (SWF), etc. and is a crucial part of many platforms like Linux, Mac OS X, iOS, XBox, Playstation, Wii and so on.

Requirements

Target Platforms: Windows 11, Windows 10, Windows 7, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later)
