Constructor & Destructor Documentation

pdftron::Filters::FlateEncode::FlateEncode	(	Filter	input_filter,
		int	compression_level = -1,
		ULong	buf_sz = 256
	)

Constructor for Flate encoder.

Parameters:

	input_filter	the input data stream
	compression_level	must be a number between 0 and 9: 1 gives best speed, 9 gives best compression, 0 gives no compression at all (the input data is simply copied a block at a time), -1 requests a default compromise between speed and compression (currently equivalent to level 6).
	buf_sz	filter buffer size (in bytes).
