 Protected Function GZip(Source As FolderItem, Destination As FolderItem, CompressionLevel As Integer = zlib.Z_DEFAULT_COMPRESSION, Overwrite As Boolean = False) As Boolean
 Protected Function GZip(Source As MemoryBlock, Destination As FolderItem, CompressionLevel As Integer = zlib.Z_DEFAULT_COMPRESSION, Overwrite As Boolean = False) As Boolean
 Protected Function GZip(Source As Readable, Destination As FolderItem, Overwrite As Boolean = False, CompressionLevel As Integer = zlib.Z_DEFAULT_COMPRESSION) As Boolean

##Parameters

Name	Type	Comment
Source	FolderItem, Readable, MemoryBlock	The data to compress
Destination	FolderItem, Writeable	The file or stream to which compressed data should be written. Methods which return a MemoryBlock do not have this parameter
CompressionLevel	Integer	Optional. If specified, the compression level (0=none, 1=fast, 9=best) to use

##Return value Returns True if there were no errors writing to a Writeable or FolderItem; or, a MemoryBlock containing the compressed data.

##Notes Compresses data from the Source argument into the Destination argument using GZip; methods without a Destination argument return the compressed data instead.
