Member Function Documentation

accumulate()

template<class _CSTrait >

void KoMixColorsOpImpl< _CSTrait >::MixerImpl::accumulate ( const quint8 * data, const qint16 * weights, int weightSum, int nPixels )

inlineoverridevirtual

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

Implements KoMixColorsOp::Mixer.

Definition at line 316 of file KoMixColorsOpImpl.h.

    {
        result.accumulateColors(PointerToArray(data, _CSTrait::pixelSize), WeightsWrapper(weights, weightSum), nPixels);
    }

accumulateAverage()

template<class _CSTrait >

void KoMixColorsOpImpl< _CSTrait >::MixerImpl::accumulateAverage ( const quint8 * data, int nPixels )

inlineoverridevirtual

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.

Implements KoMixColorsOp::Mixer.

Definition at line 321 of file KoMixColorsOpImpl.h.

    {
        result.accumulateColors(PointerToArray(data, _CSTrait::pixelSize), NoWeightsSurrogate(nPixels), nPixels);
    }

computeMixedColor()

template<class _CSTrait >

void KoMixColorsOpImpl< _CSTrait >::MixerImpl::computeMixedColor ( quint8 * data )

inlineoverridevirtual

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

Implements KoMixColorsOp::Mixer.

Definition at line 326 of file KoMixColorsOpImpl.h.

    {
        result.computeMixedColor(data);
    }

currentWeightsSum()

template<class _CSTrait >

qint64 KoMixColorsOpImpl< _CSTrait >::MixerImpl::currentWeightsSum ( ) const

inlineoverridevirtual

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.

Implements KoMixColorsOp::Mixer.

Definition at line 331 of file KoMixColorsOpImpl.h.

    {
        return result.currentWeightsSum();
    }
