new :
stream : Stream *
mode : CompressionMode *
level : CompressionLevel -> ZlibStream
new :
stream : Stream *
mode : CompressionMode *
level : CompressionLevel -> ZlibStream Parameters
- stream (Stream)
- The stream to be read or written while deflating or inflating.
- mode (CompressionMode)
- Indicates whether the ZlibStream will compress or decompress.
- level (CompressionLevel)
- A tuning knob to trade speed for effectiveness.
Remarks
When mode is CompressionMode.Decompress, the level parameter is ignored.
The "captive" stream will be closed when the ZlibStream is closed.
Examples
This example uses a
ZlibStream to compress data from a file, and writes the
compressed data to another file.
