granularity()

virtual float Digikam::DImgLoaderObserver::granularity ( )

inlinevirtualinherited

Return a relative value which determines the granularity, the frequency with which the DImgLoaderObserver is checked and progress is posted. Standard is 1.0. Values < 1 mean less granularity (fewer checks), values > 1 mean higher granularity (more checks).
