Description
Creates and initializes an instance of a TZCompressionStream object.
Call Create to instantiate a TZCompressionStream object.
The CompressionLevel parameter determines the type of compression algorithm to be used, and must be one of the following: clNone, clFastest, clDefault, or clMax.
The Dest parameter is a TStream object; compressed data will be written to this stream.
The WindowBits parameter determines the buffer handling. Zero indicates the zlib header to determine the buffer size. Values between 8 and 15 set the buffer size, negative values indicate the raw processing, and adding to 16 forces the gzip handling.
