Member Function Documentation

accumulate()

virtual void KoMixColorsOp::Mixer::accumulate ( const quint8 * data, const qint16 * weights, int weightSum, int nPixels )

pure virtual

Add nPixels pixels pointed by data to the mixing sum. The passed pixels are weighted by coefficients in weights.

Implemented in KoMixColorsOpImpl< _CSTrait >::MixerImpl.

accumulateAverage()

virtual void KoMixColorsOp::Mixer::accumulateAverage ( const quint8 * data, int nPixels )

pure virtual

Add nPixels pixels pointed by data to the mixing sum. The passed pixels are weighted uniformly, that is, each pixel has implicit weight of 1.

Implemented in KoMixColorsOpImpl< _CSTrait >::MixerImpl.

computeMixedColor()

virtual void KoMixColorsOp::Mixer::computeMixedColor ( quint8 * data )

pure virtual

Calculate the final mixed color. This function may be called as many times as needed on any stage of the mixing.

Implemented in KoMixColorsOpImpl< _CSTrait >::MixerImpl.

currentWeightsSum()

virtual qint64 KoMixColorsOp::Mixer::currentWeightsSum ( ) const

pure virtual

Return the current sum of the weights of the averaging algorithm. That might be needed to make a decision whether we had a meaningful amount of data passed.

Implemented in KoMixColorsOpImpl< _CSTrait >::MixerImpl.
