		int	bits = -1,
		const vec4i &	crop = vec4i::Zero() )

Set pre-processing options, possibly overriding some of the configured settings.

A value of -1 in the integer parameters means that this setting will not be changed.

Sets a Progress interface the algorithm can use to notify observers about its computing progress.
