28 Args:
29 string (bytes): The input data.
30 mode (int, optional): The compression mode; value 0 should be used for
31 generic input (MODE_GENERIC); value 1 might be beneficial for UTF-8 text
32 input (MODE_TEXT); value 2 tunes encoder for WOFF 2.0 data (MODE_FONT).
33 Defaults to 0.
34 quality (int, optional): Controls the compression-speed vs compression-
35 density tradeoff. The higher the quality, the slower the compression.
36 Range is 0 to 11. Defaults to 11.
37 lgwin (int, optional): Base 2 logarithm of the sliding window size. Range
38 is 10 to 24. Defaults to 22.
39 lgblock (int, optional): Base 2 logarithm of the maximum input block size.
40 Range is 16 to 24. If set to 0, the value will be set based on the
41 quality. Defaults to 0.

43 Returns:
44 The compressed byte string.
