DeflateCompressor(;level=-1, windowbits=-1)

Create a deflate compression codec.

Arguments

• level: compression level (-1..9)
• windowbits: size of history buffer (8..15)
• memlevel: memory size used for internal compression state (1..9)
• strategy: compression strategy
  • 0 <-> ZDEFAULTSTRATEGY
  • 1 <-> Z_FILTERED
  • 2 <-> ZHUFFMANONLY
  • 3 <-> Z_RLE
  • 4 <-> Z_FIXED

DeflateCompressorStream(stream::IO; kwargs...)

Create a deflate compression stream (see DeflateCompressor for kwargs).

DeflateDecompressor(;windowbits=15)

Create a deflate decompression codec.

Arguments

• windowbits: size of history buffer (8..15)

DeflateDecompressorStream(stream::IO; kwargs...)

Create a deflate decompression stream (see DeflateDecompressor for kwargs).

GzipCompressor(;level=-1, windowbits=15)

Create a gzip compression codec.

Arguments

• level: compression level (-1..9)
• windowbits: size of history buffer (8..15)

GzipCompressorStream(stream::IO; kwargs...)

Create a gzip compression stream (see GzipCompressor for kwargs).

GzipDecompressor(;windowbits=15, gziponly=false)

Create a gzip decompressor codec.

If gziponly is false, this codec can decompress the zlib format as well.

Arguments

• windowbits: size of history buffer (8..15)
• gziponly: flag to inactivate data format detection

GzipDecompressorStream(stream::IO; kwargs...)

Create a gzip decompression stream (see GzipDecompressor for kwargs).

ZlibCompressor(;level=-1, windowbits=15)

Create a zlib compression codec.

Arguments

• level: compression level (-1..9)
• windowbits: size of history buffer (8..15)

ZlibCompressorStream(stream::IO)

Create a zlib compression stream (see ZlibCompressor for kwargs).

ZlibDecompressor(;windowbits=15)

Create a zlib decompression codec.

Arguments

• windowbits: size of history buffer (8..15)

ZlibDecompressorStream(stream::IO; kwargs...)

Create a deflate decompression stream (see ZlibDecompressor for kwargs).
