Nevron.Nov.Compression Namespace / NCompression Class / CompressZlib Method / CompressZlib(Stream,Stream,ENCompressionLevel,Boolean) Method
The stream that contains the data to compress.
The stream to write the compressed data to.
The compression level to apply.
Determines whether to close the output stream when the compression has finished or not.

       ENCompressionLevel compressionLevel,
       System.bool closeOutputStream

    Parameters

    input
    The stream that contains the data to compress.
    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.
