◆ canSave()

bool LASFilter::canSave	(	CV_CLASS_ENUM	type,
		bool &	multiple,
		bool &	exclusive
	)		const

overridevirtual

Returns whether this I/O filter can save the specified type of entity.

Parameters

type	entity type
multiple	whether the filter can save multiple instances of this entity at once
exclusive	whether the filter can only save this type of entity if selected or if it can be mixed with other types

Returns: whether the entity type can be saved
