new :
stream : Stream *
mode : CompressionMode *
level : CompressionLevel -> DeflateStream
new :
stream : Stream *
mode : CompressionMode *
level : CompressionLevel -> DeflateStream Parameters
- stream (Stream)
- The stream to be read or written while deflating or inflating.
- mode (CompressionMode)
- Indicates whether the DeflateStream 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 DeflateStream is
closed.
Examples
This example uses a DeflateStream to compress data from a file, and writes
the compressed data to another file.
