Member Function Documentation

void libdar::compressor::change_algo	(	compression	new_algo,
		U_I	new_compression_level
	)

changes compression algorithm used by the compressor

Parameters:

[in]	new_algo	defines the new algorithm to use
[in]	new_compression_level	defines the new compression level to use.

Note:

valid value for new_compression_level range from 0 (no compression) to 9 (maximum compression).
