composite() [4/4]

template<typename _impl >

void KoCompositeOp::composite	(	quint8 *	dstRowStart,
		qint32	dstRowStride,
		const quint8 *	srcRowStart,
		qint32	srcRowStride,
		const quint8 *	maskRowStart,
		qint32	maskRowStride,
		qint32	rows,
		qint32	numColumns,
		float	opacity,
		const QBitArray &	channelFlags = QBitArray() ) const

Parameters

dstRowStart	pointer to the start of the byte array we will composite the source on
dstRowStride	length of the rows of the block of destination pixels in bytes
srcRowStart	pointer to the start of the byte array we will mix with dest
srcRowStride	length of the rows of the block of src in bytes pixels (may be different from the rowstride of the dst pixels, in which case the smaller value is used). If srcRowStride is null it is assumed that the source is a constant color.
maskRowStart	start of the byte mask that determines whether and if so, then how much of src is used for blending
maskRowStride	length of the mask scanlines in bytes
rows	number of scanlines to blend
numColumns	length of the row of pixels in pixels
opacity	transparency with which to blend
channelFlags	a bit array that determines which channels should be processed (channels are in the order of the channels in the colorspace)
