Reimplemented in KoGenericRGBHistogramProducer, and KoGenericLabHistogramProducer.

◆ count()

qint32 KoBasicHistogramProducer::count ( )

◆ externalToInternal()

virtual int KoBasicHistogramProducer::externalToInternal ( int ext )

inlineprotectedvirtual

The order in which channels() returns is not the same as the internal representation, that of the pixel internally. This method converts external usage to internal usage. This method uses some basic assumptions about the layout of the pixel, so extremely exotic spaces might want to override this (see makeExternalToInternal source for those assumptions)

Definition at line 74 of file KoBasicHistogramProducers.h.
