transform()

template<typename _channel_type_ , typename traits >

void KisBurnShadowsAdjustment< _channel_type_, traits >::transform ( const quint8 * src, quint8 * dst, qint32 nPixels ) const

inlineoverridevirtual

This function apply the transformation on a given number of pixels.

Parameters

src	a pointer to the source pixels
dst	a pointer to the destination pixels
nPixels	the number of pixels

This function may or may not be thread safe. You need to create one KoColorTransformation per thread.

Implements KoColorTransformation.
