zlib.ZStream.Create

zlib.ZStream.Create

Method Signatures

 Shared Function Create(OutputStream As Writeable, CompressionLevel As Integer = zlib.Z_DEFAULT_COMPRESSION, CompressionStrategy As Integer = zlib.Z_DEFAULT_STRATEGY, Encoding As Integer = zlib.DEFLATE_ENCODING, MemoryLevel As Integer = zlib.DEFAULT_MEM_LVL) As zlib.ZStream
 Shared Function Create(OutputStream As FolderItem, CompressionLevel As Integer = zlib.Z_DEFAULT_COMPRESSION, CompressionStrategy As Integer = zlib.Z_DEFAULT_STRATEGY, Overwrite As Boolean = False, Encoding As Integer = zlib.DEFLATE_ENCODING, MemoryLevel As Integer = zlib.DEFAULT_MEM_LVL) As zlib.ZStream

Parameters

Name	Type	Comment
OutputStream	Writeable, FolderItem	Compressed output will be written to this object
CompressionLevel	Integer	Optional. The compression level for the stream. Valid levels are 1(fast) to 9(best)
Overwrite	Boolean	Optional. If True, the OutputStream FolderItem is overwritten if it exists.
CompressionStrategy	Integer	Optional. The compression strategy for the stream.
Encoding	Integer	Optional. The type of compression.
MemoryLevel	Integer	Optional. The memory level.

Return value

A new instance of ZStream, or Nil on error

Notes

Creates a new deflate stream for writing. Compressed data will be written to the OutputStream object.
