Example

This example creates an in-memory compression stream by calling Constructor(MemoryBlock), and writes some data that will be compressed using GZip at maximum compression:

  Dim output As New MemoryBlock(0)
  Dim compressor As New zlib.ZStream(output, zlib.Z_BEST_COMPRESSION, zlib.Z_DEFAULT_STRATEGY, zlib.GZIP_ENCODING)
  compressor.Write("Hello, world!")
  compressor.Close
