# Method Bz2.Deflate()->create()

Method create

  `Bz2.Deflate Bz2.Deflate(`int(1..9)`|`void` `block_size`)`

Description

  If given, `block_size` should be a number from 1 to 9 indicating the block size used when doing compression. The actual block size will be a 100000 times this number. Low numbers are considered 'fast', higher numbers are considered 'slow' but give better packing. The parameter is set to 9 if it is omitted.

  This function can also be used to re-initialize a Bz2.Deflate object so it can be re-used.
