Member Function Documentation

◆ description()

QString OnlyIdenticalMergeStrategy::description ( ) const

Returns: a description of this merge strategy

Implements KisMetaData::MergeStrategy.

{
    return i18n("Keep only meta data that are identical");
}

◆ id()

QString OnlyIdenticalMergeStrategy::id ( ) const

Returns: the id of this merge strategy

◆ merge()

void OnlyIdenticalMergeStrategy::merge	(	Store *	dst,
		QList< const Store * >	srcs,
		QList< double >	scores ) const

overridevirtual

Call this function to merge a list of meta data stores in one.

Parameters

dst	the destination store
srcs	the list of source meta data store
scores	a list of score which defines the importance of each store compared to the other the sum of score is expected to be equal to 1.0. One way to attribute a score is to compute the area of each layer and then to give a higher score to the biggest layer. srcs and scores list must have the same size.
